Drain pipe trash gains easily at the drainage controller. Be sure
to install a stopper and a structure that cleans up trash easily.
Trial draining of the drain pipe
Open the side panel of the indoor unit, fill water inward, and
check whether the water can be drained smoothly. Check water
leak at the joint.
Heat insulation of drain pipe
After making sure that the water drains smoothly and no water is
leaked, use adiabatic wool bushes to preserve heat of the drain
pipe. Otherwise, condensate will occur.
NOTE

ELECTRIC CONNECTION
Use special power supply for the air conditioner. Design power
supplies specific to the indoor unit and outdoor unit. The supply
voltage must comply with the nominal voltage.
The external supply circuit of the air conditioner must have a
ground wire, and the power supply ground wire of the indoor unit
must be connected with the external ground wire firmly.
The wiring must be performed by professional technicians
according to the circuit diagram labels.
Distribute the wires according to the relevant electric technical
standards promulgated by the State, and set the Residual
Current-operated Circuit Breaker (RCCB) properly.
The power wire and the signal wire shall be laid out neatly and
properly, without mutual interference or contacting the connec-
tion pipe or valve.
No power cable is attached to this equipment. The user can
select the power cable by reference to the stipulated power
supply specifications. No joint of wires is allowed.
Upon completion of wire connection, double check it and then
connect the power supply.
An all-pole disconnection device which has at least 3mm
separation distance in all pole and a residual current

in the fixed wiring according to the national rule.
The appliance shall be installed in accordance with national
wiring regulations.

Procedure of using stop valve
Open the spool until it touches the stop block. Do not attempt to
open further.
Use a spanner or a similar tool to tighten the bonnet. The bonnet
tightening torque is shown in aboveTable “Tightening torque”.
Upon completion of installation, open all valves before trial run.
Each unit has two valves of different sizes located at the outdoor
unit side. Of the two valves, one is gas valve and the other is
liquid valve. The procedure of opening/closing the valve is
shown in the right figure (
Fig.6-5)
.
Procedure of opening the valve: Open the square-head cover,
use a spanner to capture the square head and open it
thoroughly. Then tighten the square-head cover.
Procedure of closing the valve: Same as the procedure of
opening the valve, but rotate the spanner clockwise thoroughly.
Use soap water or a leak detector to check whether gas leakage
exists at the adapters.
Use heat insulation materials to wrap the part protruding outside
the flared pipe joint and the refrigerant pipe of the liquid pipe and
the gas pipe, and ensure that no gap exists between them.
Imperfect heat insulation may lead to condensate drips.
Install the drain pipe of the indoor unit
In order to prevent drain overflow, install a drainage controller at
place 1 of the drain pipe. (The drainage controller is designed to
smoothen the drainage when the static pressure outside the unit
is high, especially at the air inlet, in addition to remove stink
through the drain pipe.)
The drain of water is natural. In the construction, the external
pipe of the outdoor unit slants downward at a gradient of
a
The number of bends and folds of the drain pipe should not
exceed 2. Try to avoid bends in order to prevent trash accumula-
tion.
In the construction, do not drop trash into the drip tray or drain
pipe of the indoor unit.
Upon completion of installing the drain pipe, remove the inspec-
tion panel. Put water into the drip tray to check whether the water
can be drained levelly and steadily.
