INSTALLATION (CONTINUED)
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.
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.
5.Perform a leak test on all copper tube connections. To prevent heat loss and damage to walls from con- densation, the copper tube connections coming from the wall must be insulated. Do this by wrapping foam rubber or equivalent around the connection approxi- mately 8mm thick so no copper tubing is exposed.
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 con- nection or extension. Also, do not crease or form a trap in the tubing.
