Certified technician will diagnose your ductless mini split system, and offer professional repair estimate. Traditionally in North America ducted air heat pumps have been used for cooling, and also for heating in winter. Typically a large unit is installed which serves the entire house through a duct system installed during construction. The warm and cold sides of the pump are contained in a single unit. In recent years the ductless split heat pump has been introduced. The warm and cold sides of the pump are contained in separate units, connected by refrigerant lines.http://seftrade.cz/files/94-vitara-workshop-manual.xml
A mini-split unit can serve a single room, while a dual or triple split unit can serve two or three rooms with separate indoor units connected to a single outdoor unit. The compressor is located in the outdoor unit, while the indoor unit is relatively small and lightweight. Since the refrigerant lines are of modest diameter, and the indoor units small, these systems can be retrofitted to an existing house relatively easily with minimal disruption. Add Tip Ask Question Comment Download Step 1: Preparation (these instructions were written for the Senville Aura series; there are a number of similar units by other manufacturers such as Fujitsu and Lennox) The first step is to determine the correct size of heat pump. For a given location, climate records will give an outdoor temperature range. This may have already been done as part of the original building design. Alternatively, one might estimate it based on floor area and local construction practice. The next step is to determine suitable locations for the components (indoor and outdoor units). For the Aura, the indoor unit weighs about 10kg and is designed to be mounted high on an exterior wall. The outdoor unit weighs about 40kg and can be mounted on a concrete slab, on a bracket hung from a wall, or on a metal stand. Consult the installation manual for recommended clearances. The outdoor unit should not be exposed to severe weather and should not be located where it can suck in debris, dirt, leaves etc. In operation, it will blow warm air (when cooling), or cold air (when heating), so should probably not be sited next to a patio etc.For the Aura, the maximum allowed line length is 20m, and the maximum difference in height is 8m. In addition to the lines and cable, both units have a condensate drain, which should be routed outside using pipe with a consistent downward slope.http://www.czytamzezrozumieniem.pl/userfiles/94-volvo-850-service-manual.xml
If no engineering drawings are available for the units, it may be necessary to make measurements yourself to determine the location of mounting brackets and service lines. The outdoor unit is significantly noisier (54dBA) than the indoor unit (37dBA); it should probably not be near an open window. The smaller Aura set requires nominal 230V split-phase AC at 9A, on a 15A breaker. Larger sets may require 20A or 25A service. The indoor unit(s) are powered from the outdoor unit. Since regular outlets are probably nominal 115V, and the heatpump should have a dedicated breaker, it is probably necessary to run new cable from a breaker panel to the outdoor unit location. The Aura is shipped with refrigerant line stubs folded inside the back of the unit. There are cutouts on either side of the case, so the lines may be routed out the left side across the wall, through a hole in the wall behind the unit of the left, or the lines may be bent straight and routed directly through the wall behind the unit on the right. Alternatively they could, with care, be bent to the right. It is necessary after installation to connect the refrigerant lines, so the geometry must allow access (not locate the joins inside a wall, for instance). If the indoor unit is mounted on wood-frame construction, at least one bracket should be secured to a wall stud. Ideally a backing plate should be used if there are not two studs available at suitable locations, though cavity-wall toggles to hold 5kg should be adequate. All measurements and planning should be done before drilling a single hole - try not to have the coolant lines emerge behind a downpipe that cannot be moved, or sever a wall stud or water pipe. Add Tip Ask Question Comment Download Step 2: Tools You need regular tools to screw things to a wall - drill, screwdriver, wrench etc.You need a stud finder to locate studs in a wood-frame wall. You need fish tape to fish electrical wire - at least, it helps.
For cutting and fitting the refrigerant lines, you need a tube cutter. The Aura uses flare nuts, so you need a flaring tool. You can bend copper tube by hand, but for a small radius you need a tube bending tool - the tube can buckle if bend too sharply by hand. To tighten flare nuts, ideally you should use a flare nut wrench of the correct size which is less likely to slip or damage the nut. It is possible to make these from ring spanners by cutting the ring with a carbide disk - the resulting slot fits over the pipe so the wrench can be slid sideways over the nut. The Aura installation specifies a particular torque for each pipe size. You can obtain a suitable torque wrench, use a socketed torque system with a crows-foot wrench, or use a spring balance with some simple math to account for the length of the flare wrench. Purging the refrigerant lines requires a vacuum pump and pressure gauge. Add Tip Ask Question Comment Download Step 3: Installing the Indoor Unit Check measurements to ensure that the through holes will be in a good location both inside and outside. You will need to measure carefully from an opening such as a door or window. Remember that floor and ground levels may be different inside and out, while interior walls may not line up between floors. Secure the mounting plate to the wall, or at least mark the location, then drill the through holes for the refrigerant lines, cable, and condensate drain. These holes should slope slightly downwards towards the outside to discourage water ingress. The Aura kit comes with a plastic liner and trim ring, though this is too short for a thicker wall. ABS plumbing pipe may be used to support or conceal the lines in a longer run. Route the terminated and insulated refrigerant lines, the drain line and the cable. The Aura requires 4-conductor cable (two supply lines for 230V, a signalling wire and ground wire). Mount the unit on the mounting plate and connect the inter-unit cable and condensate drain.
Fasten the flare nuts on the refrigerant lines but leave the fittings exposed for leak testing later. Add Tip Ask Question Comment Download Step 4: Installing the Outdoor Unit Locate the outdoor unit in the desired location with a good route for the refrigerant lines, mark the mounting bolt locations, and drill the mounting holes. Fasten the unit in position. If using wall brackets, make sure they are securely fastened to the wall - with wood-frame construction, secure them to studs with lag bolts. Connect the inter-unit cables to the outdoor unit. Route the cables with a downward loop so that water does not track down the cable into the unit. Cut the refrigerant lines to length, re-fit any insulation if required, thread the flare nuts onto the end of the pipe and flare the ends. Ensure there is enough slack to allow connection to the unit without sharp bends, and preferably enough to cut and re-flare the end if the first attempt is not satisfactory. Connect the lines. Connect the 230V power lines, ensuring that the unit is properly grounded. Add Tip Ask Question Comment Download Step 5: Purging the Refrigerant Lines Consult the installation instructions. The Aura is pre-charged with refrigerant, though if refrigerant lines more than 7.5m are required, additional refrigerant must be added. The refrigerant lines and indoor unit coils must be pumped down and allowed to outgas any moisture. Pump the lines down for at least 20 minutes, ideally longer, and make sure the pressure does not rise significantly when the pump valve is closed at the end of this period. Open the packed valves to allow refrigerant into the lines, disconnect the coupler (closing the Schrader valve), and leak-test all the joints including those on the indoor units. Close up the indoor units, connect the power, turn the system on and test it. While the Aura installation instructions suggest leak-testing using soapy water, this may be illegal in some jurisdictions.
Leak testing to a positive pressure with dry nitrogen prior to introducing refrigerant is preferred. In some jurisdictions, installation or even purchase must be done by a licenced technician. Add Tip Ask Question Comment Download Share it with us! I Made It! Recommendations Fermentation Quilt I'm not trying to be disrespectful but there is a lot wrong with the above Instructable. In the HVAC world you never come across flare fittings for a reason, they leak. Also you should never use a vacuum pump as a indicator of a leak. At the most you are putting 15psi pressure on the outside pulling in. Properly done you purge the lineset with dry Nitrogen to 150 psi and wait 30 minutes and check for a difference. Then you pull a vacuum but not just any vacuum you want a vacuum to 500 microns or lower. When your pulling a vacuum your extracting all the non-condensables out like air and water. If there is water in the lineset and pull a vacuum without a micron gauge you have no idea how good of a vacuum your pulling and running a risk of shortening the life of your compressor. Or hooking up a micron gauge to your vacuum pump directly to see if it can even pull 500 or lower microns. When you reduce pressure you lower the boiling point of water from 212 degrees f to 70 degrees or lower causing water to boil at room temperature and extracting all the water. 250 microns is considered a deep vacuum and is best but 500 is mandated by the EPA. As you can guess this is my first attempt at a heatpump system, and I'd probably do things differently a second time. There was a local rebate program, my ceiling heating was broken, so I bought the cheapest system I could find on the basis that if it worked I'd get the cost back fairly rapidly in lower heating bills, and anyway how hard could it be. The AURA series do indeed use flare fittings. Maybe more expensive or better engineered models don't. Some of what I wrote is more-or-less straight out of their installation manual.
The unit is probably manufactured in China for a US company, but the instructions were written in the US and translated to metric for the Canadian market, which is where I bought it. So I was basically following the manufacturers instructions rather than using a textbook. I was using a Tri Vac roughing pump as used for physics experiments, with an Pirani pressure gauge. I figured that was probably good enough - no need to go to a turbo pump and get 10 microns or whatever, seeing as the installation manual shows a bourdon gauge and the only point I could see in pumping down was to remove any moisture from the system as you say. 0 OpticHash adaviel I hope I didn't sound critical or harsh about my opinions. Most mini-splits have flare fittings but I prefer not to use them. Flares are great, they are easy to disconnect. You don't really need a micron gauge but without one your not sure if your still drawing out moisture. Actually I lied in the US your required to pull a vacuum of 500 microns or less according to the EPA so basically implying you need something to measure microns. Are you happy with your heat pump? 0 mspice2 Nice simple how to for people not in the know how though 0 bestchoicecar.nyc Can these pre existing lines be used. And what would be the results of using a bigger diameter line? 0 Jamesmiller When we are going for installation of heat pumps, many times we are not satisfy with the service or price. To get a satisfactory service we have to choose a right - experienced service provider.Thanks for such an insightful posting. 0 adaviel Some jurisdictions may have regulations which mandate alternate installation or commissioning steps. It may be required to use the services of a professional HVAC technician for commissioning. 0 OpticHash EPA is performing random inspections, responding to tips, and pursuing potential cases against violators.

NOTICEUse appropriate oil with R410A systems. Oil type is found at the bottom of Connection Pipe Requirements table (included in the outdoor unit installation manual). R-410A systems utilize POE (Polyolester) or PVE(Polyvinyl Ether) oil. Both oil types absorb moisture readily, yet, lubrication properties vary. 4 Do not leave the sealed System open to atmosphere except during service for a short period of time. If the sealed System is left open longer than four hours, the compressor oil must be changed. These systems utilize strainers placed before and after the expansion device in the outdoor unit, if debris or moisture is suspected, these strainers must be changed. Do not break a vacuum with air. Do not leak check the sealed System with compressed air. Unless instructed by factory service representative, external refrigeration driers are prohibited.In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain chlorofluorocarbons (CFC's) and those containing hydro-chlorofluorocarbons (HCFC's). 5 Not all refrigerants containing these compounds have the same potential impact to the environment. The Company advocates the responsible handling of all refrigerants, including industry replacements for CFC's such as HCFC's and HFC's.
Responsible refrigerant PracticesThe manufacturer believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified. The Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for responsible management of refrigerants.

If it is not running, make sure the breakers in your home’s breaker box or electrical panel are in the ON position. Make sure it’s in the ON position. If the system is set for cooling, the blower motor should be running. If not, check to make sure your indoor unit switch is in the ON position. If you have one-inch-thick furnace filters, a once-a-month change is recommended. If you don’t change it, the filter will eventually block the proper airflow and cause your outdoor air conditioner unit to shut down. Return air grilles are larger and are located on a wall or the ceiling in newer homes. Older homes frequently have return air grilles on the floor. NOTE: If your system control has a “Constant ON” feature, you will not always feel warmth, even though air may be blowing. If it isn’t, your system won’t know to provide heating. Try turning the fan to ON using the fan switch on the control or thermostat to test for power to the furnace. If you have one-inch-thick furnace filters, a once-a-month change is recommended. If you don’t change it, the filter will block the proper airflow and strain your furnace. Return air grilles are larger and are located on a wall or the ceiling in newer homes. Older homes frequently have return air grilles on the floor. NOTE: If your system control has a “Constant ON” feature, you will not always feel warmth, even though air may be blowing.
