Removal Of Air From The Pipe And Gas Leakage Inspection
Gas Leakage Inspection
Please use gas leakage detector to check if
leakage occurs at the connection of Flare nut
as shown on the right.
If gas leakage occurs, further tighten the
connection to stop leakage.

Procedures of using Vacuum Pump for Air Removal
As shown in figure on the right,
remove the cap of valve head and
valve core and then connect them
to the vacuum pump and manifold
valve.
Fully tighten the “Hi” shuttle of the
manifold valve and completely
unscrew the “Lo” shuttle. Run the
vacuum pump for about 10–15
minutes, then completely tighten the
“Lo” shuttle and switch off the
vacuum pump.
2
Completely unscrew the spindle of
the service valve (at 2 places) in
anti-clockwise direction to allow the
flow of coolant (using Hexagonal
Wrench key).
3
Remove the Charge hose and
tighten the cap of valve head. The
task is then completed.

Preparation of Pipe
1
●
Use a pipe cutter to cut the copper pipe.
●
Jagged edge will cause leakage.
●
Point the side to be trimmed downwards during trimming to prevent copper
chips from entering the pipe.
●
Before flaring, please put on the flare nut.

You may not be able to close the side
cover due to the connecting cord, under
such situation, please press against the
wall of side cover to fix it.
●
Be sure that the hooks (6 places) are
plugged in.
Otherwise, water leakage may occur and
this causes short circuit or faults.
Checking for the electric source
and the voltage range
●
Before installation, the power source must be checked and
necessary wiring work must be completed. To make the
proper wiring capacity, use the wire gauges list below for
the lead-in from a pole transformer and for the wiring from a
switch board of fuse box to the outlet in consideration of the
locked rotor current.
●
Investigate the power supply capacity and other
electrical conditions at the installation location.
Depending on the model of room air conditioner to
be installed, request the customer to make
arrangements for the necessary electrical work etc.
The electrical work includes the wiring work up the
outlet. In localities where electrical conditions are
poor, use of a voltage regulation is recommended.

●
The naked part of the wire core should be 10 mm and fix
it to the terminal tightly. Then try to pull the individual wire
to check if the contact is tight. Improper insertion may
burn the terminal.
●
Be sure to use only power cables approved from the
authorities in your country. For example in Germany: Cable
type: NYM 3x1.5mm

, (fuse = 20A time delay)
●
Please refer to the installation manual for wire connection
to the terminals of the units. The cabling must meet the
standards of electrical installation.
●
There is a AC voltage of 240V between the L and N
terminals. Therefore, before servicing, be sure to remove
the plug from the AC outlet or switch off the main switch.

OUTDOOR UNIT
●
Please mount the Outdoor unit on stable ground to prevent vibration
and increase of noise level.
●
Decide the location for piping after sorting out the different types of
pipe available.
●
When removing side cover, please pull the handle after undoing the
hook by pulling it downward.
Please face this side (suction

BASE
DRAIN PIPE
CONDENSED WATER DISPOSAL OF OUTDOOR UNIT
There are holes on the base of Outdoor unit for condensed
water to exhaust.
In order to flow condensed water to the drain, the unit is installed on a
stand or a block so that the unit is 100mm above the ground as shown
figure. Join the drain pipe to one hole.
At first insert one portion of the hook to the base (Portion A), then pull the
drain pipe in the direction shown by the arrow while inserting the hook
into the base. After installation, check whether the drain pipe cling to the
base firmly.
When Using and Installing In Cold Areas
When the air conditioner is used in low temperature and in snowy
conditions, water from the heat exchanger may freeze on the base surface
to cause poor drainage. When using the air conditioner in such areas, do
not install the bushings. Keep a minimum of 250mm between the drain
hole and the ground. When using the drain pipe, consult your sales agent.
For more details, refer to the installation Manual for Cold Areas.

●
The connected terminals should be completely sealed with
heat insulator and then tied up with rubber strap.
●
Please tie the pipe and power line together with vinyl tape as
shown in the figure showing the installation of Indoor and
Outdoor units. Then fix their position with holders.
●
To enchance the heat insulation and to prevent water
condensation, please cover the outdoor part of the drain hose
and pipe with insulation pipe.
●
Completely seal any gap with putty.
Installation Of Remote Controller

●
The remote controller can be placed in its holder which is
fixed on wall or beam.
●
To operate the remote controller at its holder, please ensure
that the unit can receive signal transmitted from the controller
at the place where the holder is to be fixed. The unit will beep
when signal is received from the remote controller. The signal
transmission is weaken by the fluorescent light. Therefore,
during the installation of the remote control holder, please
switch on the light, even during day time, to determine the
mounting location of the holder.
Power Source
CAUTION
!
●
Please use a new socket. Accident may occur due to the use of old
socket because of poor contact.
●
Please plug in and then remove the plug for 2 – 3 times. This is to
ensure that the plug is completely plugged into the socket.
●
Keep additional length for the power cord and do not render the
plug under external force as this may cause poor contact.
●
Do not fix the power cord with U-shape nail.
Operation Test
●
Please ensure that the air conditioner is in normal
operating condition during the operation test.
●
Explain to your customer the proper operation
procedures as described in the user’s manual.
The controller must
be hooked onto the
hook at the lower
part of the holder.
Push in the remote
controller in the
direction as shown
in figure below.
