1. For Concrete or similar type wall make holes into the wall and insert concrete nails instead of screws MOUNTING THE INDOOR UNIT The Indoor unit must be mounted before connecting the indoor outdoor wire drain hose and copper tubing To mount follow the procedures below 1 The tubing can be extended in 4 directions as shown below No cutting is necessary for left rear and right rear tubing connections If using left or right tub ing connections remove the plastic area with a hack saw so pipes can go through Left Rear 2 Make sure the drain hose and copper tubing are wrapped with the rubber insulation Using the tape wrap the indoor outdoor wire copper tubing and drain hose together CAUTION Make sure the Indoor units cord is not connect ed to AC power when performing these procedures Be sure to comply with local codes on running a wire from the indoor to the outdoor unit DO NOT LET THE INDOOR OUTDOOR WIRE COME IN DIRECT CONTACT WITH THE TUBING OR HOSE 3 Shape the tubing so it can easily go through the hole in the wall Push the indoor outdoor wire copper tub ing and drain hose through the hole in the wall angling downward Situate the indoor unit on the wall bracket by lifting the indoor unit slightly above the wall bracket and then down so it is securely locked in
2. Air and moisture remaining in the refrigerant system may create adverse conditions as indicated below pressure in the system rises operating current rises cooling efficiency drops moisture in the refrigerant circuit may freeze and block capillary tubing water may lead to corrosion of parts in the refrigerant system Therefore the indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated to remove any noncondesables and moisture from the system AIR PURGING WITH VACUUM PUMP TEST RUN Confirm each tube narrow and wide tubes between the indoor and outdoor units has been properly connected and all wiring for the test run has been completed Remove the valve caps from the wide and narrow service valves on the outdoor unit Note that both narrow and wide tube service valves on the outdoor unit are kept closed at this stage shipping position Charge Hose Leak Test 1 With the service valves on the outdoor unit remaining closed remove the threaded cover on the wide tube service port Save for reuse 2 Attach a manifold valve with pressure gauge and dry nitro gen gas cylinder to this service port with charge hoses Nitrogen Gas Cylinder Vertical Position CAUTION Be sure to use a manifold valve for air purging If it is not avail able use a stop valve for this purpose The Hi knob of the manifold valve must always be kept closed
