•Leave enough room around the unit for air intake, exhaust and possible maintenance.

INSTALLING THE WALL BRACKET:

To install the wall bracket, follow the procedures below. One hole is required for the tubing and may be either on the left or right side.

1.Determine the type of wall (sheetrock, concrete, etc.) and make sure it is strong enough to hold indoor unit. Select an approximate position for the unit, taking the required distances away from walls/AC outlet into consideration.

2.Determine if the hole is to be made at the left or right hole location.

30mm

10mm

CAUTION

•Before making hole, make sure there are no studs, pipes, electrical wiring or conduit directly behind the area to be cut.

3.Using drill with hole-cutting attachment or equivalent, cut a hole 65mm (2.56") in diameter. The hole should be made at a slight downward slant to the outdoor side. Measure the thickness from the inside to outside edges and cut a PVC pipe at a slight angle 1/4" shorter than the thickness of the wall and insert pipe in wall.

4.For sheetrock, wooden or similar wall, measure down from the ceiling using a level or tape measure and attach the wall bracket to the wall using 4 screws. If you are not able to line up the holes with the beams, use toggle bolts. Make sure the wall bracket is even and flush against the wall.

CONNECTING COPPER TUBES

To connect the copper tubes, follow the procedures below:

1.Remove the flare nut stoppers from the inside unit. Determine the location of the copper tubing and where the bends will be. Gently bend the copper tubing, making sure to use big angles so no crimping will occur. Try to do this on the first try as repeated bending may break or crimp the tubing.

2.Remove the plastic stoppers from the tubing. Connect the large and small copper tubing to the respective extension and rotate the flare nut with your finger until a smooth match is made. Make sure the copper extension has foam rubber (insulation) on it.




coupler			Flare Nut

NOTE:

When removing the flare nut stopper from the inside unit, confirm “Ping”, sounds because the mixed gas is charged in the inside unit,

3.Once a smooth match is made, tighten the flare nut using a wrench. Be very careful not to strip the threads or flare nut. Repeat this process for the small and large tubing. When tightening the flare nut, use another wrench to securely hold the coupler from twisting and possibly damaging the tubing.

5.Perform a leak test on all copper tube connections. To prevent heat loss and damage to walls from condensation, the copper tube connections coming from the wall must be insulated. Do this by wrapping foam rubber or equivalent around the connection approximately 8mm thick so no copper tubing is exposed.

4.Remove the flare nut stoppers from the outdoor unit’s valves. Connect the larger copper tubing to the larger valve on the outdoor unit. Connect the smaller copper tubing to the smaller valve on the outdoor unit.

NOTES:

•As with all wiring and hookups on this unit, make sure the AC plug on the indoor unit is unplugged.

•Be very careful not to strip the threads or flare nut.

•When insulating the connections, use foam rubber or equivalent.

CONNECTING THE DRAIN HOSE

To connect the drain hose, follow the procedures below:

1.Connect the drain hose extension to the drain hose coming from the indoor unit by loosing the clamp on the extension using a phillips screwdriver, attaching the hoses together and then tightening the clamp.

2.Run the drain hose, slanted downward, outside. If the drain pipe is exposed

indoors, make sure it is thoroughly insulated so condensation does not ruin walls or furniture or come in contact with the AC connection or extension. Also, do not crease or form a trap in the tubing.
