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.
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.

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.

The refrigerant pipes must not exceed the maximum

heights 10m(18Kx2&24Kx2&24Kx3&28Kx4&30KX4
&36KX5&42KX5).

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 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.

CHECK AFTER INSTALLATION INSTALLER

Check Items

Is the installation reliable?

Has the gas leakage been checked?

Is the thermal insulation of the unit
sufficient?

Is the drainage smooth?

Does the power supply voltage accord
with the rated voltage specified on the
nameplate?

Are the lines and pipelines correctly
installed?

Has the unit been safely grounded?

Problems Owing to Improper Installation

The unit may drop, vibrate or make noises

May cause unsatisfactory cooling (heating)
effect

May cause condensation and water dropping

May cause condensation and water dropping

The unit may bread down or the components
may be burned out

The unit may bread down or the components
may be burned out

Risk of electrical leakage

Are the models of lines in conformity
with requirements?

Are there any obstacles near the air
inlet and outlet of the indoor and out­door units?

Have the length of refrigerating pipe
and refrigerant charge amount been
recorded?

The unit may bread down or the components
may be burned out

The unit may bread down or the components
may be burned out

It is not easy to decide the charge amount
of refrigerant.
