AUTO RANDOM RE-START FUNCTION
2. Sealing Material
•
It is possible to seal one of
the four air discharge outlet.
(Sealing two or more air dis-
charge outlet could cause a
malfunction).
•
Remove the front panel and
insert the sealing material
into the air discharge outlet
on the indoor unit to seal the
air outlet.
•
The sealing material is the
same length as the longer air
discharge outlet. If it is
desired to seal the shorter air
discharge outlet, cut the
sealing material to shorten it.
•
Push the sealing material in
about 10mm beyond the
bottom surface of the indoor
unit so that it does not touch
the air louver. Be sure not to
push the sealing material in
any farther than about 10mm.
ACCESSORY PARTS
3. Charge Operation
This operation must be done by using a gas cylinder and a precise weighing
machine. The additional charge is topped-up into the water source heat pump
unit using the suction valve via the service port.
•
Remove the service port cap.
•
Connect the low pressure side of the charging gauge to the suction service
port center of the cylinder tank and close the high pressure side of the
gauge. Purge the air from the service hose.
•
Start the air conditioner unit.
•
Open the gas cylinder and low pressure charging valve.
•
When the required refrigerant quantity is pumped into the unit, close the
low pressure side and the gas cylinder valve.
•
Disconnect the service hose from service port. Put back the service port
cap.

•
The indoor unit is provided with air discharge and air intake “knock-out” hole for duct
connection. However the connection of the short duct for air discharge is possible on
only one side.
•
The use of short duct for air discharge will improve airflow distribution if there is an
obstruction (such as a lighting fixture) or in a long, narrow room or an L-shaped room.
It also use for air-conditioning of two rooms simultaneously.
Note:
•
Avoid using the short duct on which the air discharge grille can be completely closed, to
prevent evaporator freezing.
•
In order to prevent condensation forming, be sure that there is sufficient thermal
insulation and no leakage of cool air when installing the short duct.
•
Keep the introduction of fresh air intake within 20% of total air flow. Also provide a
chamber and use a booster fan.
If there is a power cut when the unit is operating, it will automatically resume the same operating mode when the power is
restored. (Applicable only to units with this feature).
