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.

this may affect drainage. In such a region, remove bush on the
bottom face of outdoor unit for better drainage. When using
drainpipe, consult our dealer.

WARNING
G
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:

, (fuse = 30A time delay)
G
Please refer to the installation manual for wire connection to the terminals of the units. The cabling must
meet the standards of electrical installation.
G
There is a AC voltage of 220-240V 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.
Do not make any connection in the middle of the connecting cable. It may cause the wire over heated,
G
emit smoke and fire.
Insulation And Maintenance Of Pipe Connection
1
The connected terminals should be completed sealed with
G
heat insulator and then tied up with rubber strap.
G
Please tie the pipe and power line together with vinly 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
G
condensation, please cover the outdoor part of the drain hose
and pipe with insulation pipe.
G
Completely seal any gap with putty.

If you cannot attach the side cover due to the connecting cord,
press the connecting cord in direction to the front panel to fix it.
!
Be sure that the hooks of the side cover is fixed in certainly.
G
Otherwise water leakage may occur and this causes short circuit
WARNING
or faults.
G
The connecting cord should not touch to service valve and pipes.
(It becomes high temperature in heating operation.)
Checking for the electric source and the
voltage range
Before installation, the power source must be checked and necessary wiring work
G
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.

Removal Of Air From The Pipe And Gas Leakage Inspection
Procedures of using Vacuum Pump for Air Removal
As shown in right figure, remove the cap
of valve core. Then, connect the charge
hose. Remove the cap of valve head.
1
Connect the vacuum pump adapter to
the vacuum pump and connect the
charge hose to the adapter.
Fully tighten the "Hi" shuttle of the
manifold valve and completely unscrew
the "Lo" shuttle. Run the vacuum pump
2
for about 10–15 minutes, then completely
tighten the "Lo" shuttle and switch off
the vacuum pump.
Completely unscrew the spindle of the
service valve (at 2 places) in anti-
3
clockwise direction to allow the flow of
coolant (using Hexagonal Wrench key).
Remove the Charge hose and tighten
the cap of valve head. Check the cap's
4
periphery if there is any gas leakage.
The task is then completed.
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.
