INSTALLING THE OUTDOOR UNIT

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.

Do not install the outdoor unit in pits or air vents

Installing the pipes

Use suitable connecting pipes and equipment for the

refrigerant R410A.

The refrigerant pipes must not exceed the maximum

heights 10m.

Wrap all the refrigerant pipes and joints.

Tighten the connections using two wrenches working

in opposite directions.

Caution: Installation Must be Performed in Accordance

with the NEC/CEC by Authorized Personnel Only.

BLEEDING

Humid air left inside the refrigerant circuit can cause com-

pressor 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 3-

way 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. Discon-

nect the vacuum pump hose.

(8) Replace and tighten all the caps on the valves.

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 conden-

sate 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.
