INSTALLING THE OUTDOOR UNIT
INSTALLER
Location
Use bolts to secure the unit to a flat, solid floor.
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.
Install the drain fitting and the drain hose(for
model with heat pump only)
Condensation is produced and flows from the outdoor unit
when the appliance is operating in the heating mode. In order
not to disturb neighbours and to respect the environment,
install a drain fitting and a drain hose to channel the condensate water. Install the drain fitting and rubber washer on the
outdoor unit chassis and connect a drain hose to it as shown
in the figure.
Do not install the outdoor unit in pits or air vents
Installing the pipes
Use suitable connecting pipes and equipment for the
refrigerant R410A.

Caution: Installation Must be Performed in Accordance
with the NEC/CEC by Authorized Personnel Only
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.
