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.

  • 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.
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 neighbors 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.
INSTALLING THE OUTDOOR UNIT

BLEEDING

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 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. Disconnect the vacuum pump hose.
  8. Replace and tighten all the caps on the valves.
