Caution: Installation Must be Performed in
Accordance with the NEC/CEC by Authorized
Personnel Only.
Install the drain fitting and the drain hose
(for model with heat pump only)
Use bolts to secure the unit to a flat, solid surface.
When mounting the unit on a wall or the roof, make
sure the support is firmly secured so that it cannot
move in the event of intense vibrations or a strong
wind.
Do not install the outdoor unit in pits or air vents.
Installing the refrigerant lines
Use suitable refrigerant lines and equipment for
refrigerant R410A.

Wrap all the refrigerant pipes and joints.
Tighten the connections using two wrenches working in opposite directions.
BLEEDING
INSTALLER
Humid air left inside the refrigerant circuit can cause compressor malfunction. After having connected the indoor
and outdoor units, bleed the air and humidity from the
refrigerant circuit using a vacuum pump.
(1) Unscrew and remove the caps from the 2-way and 3way valves.
(2) Unscrew and remove the cap from the service valve.
(3) Connect the vacuum pump hose to the service valve.
(4) Operate the vacuum pump for 10-15 minutes until an
absolute vacuum of 10 mm Hg has been reached.
(5) With the vacuum pump still in operation, close the
low-pressure knob on the vacuum pump coupling.
Stop the vacuum pump.
(6) Open the 2-way valve by 1/4 turn and then close it
after 10 seconds. Check all the joints for leaks using
liquid soap or an electronic leak device.
(7) Turn the body of the 2-way and 3-way valves. Disconnect the vacuum pump hose.
(8) Replace and tighten all the caps on the valves.
