values an stop and from the charging port and
service port for gas stop valve.
2.
3.
Insert a key hexagon socket screw into the valve
inside of charging port for gas stop valve.
Meanwhile, unscrew the liquid stop valve open anti-
clockwise for half circle continuing 8-10 sec. Then
open the valve of charging port.
4. Open the gas stop valve an d liquid stop valve
completely using a key hexagon socket screw for
unscrewing the valve inside anti clockwise.
5. Screw the caps of service ports (for both liquid and
gas) and the charging port.
Leakage D etecting
After connecting the pipes check every joint port, service ports and the charging port and the charging port
for gas leakage with a leak detector or soapy water.
Insulation of joints and binding of piping
1. Insulate flare joints of the indoor heat exchanger and the connection piping with insulation so that no parts
of them are exposed, which will eliminate dripping of condensation.
2. The connection piping between indoor and outdoor unit should be bound with tape.
3. If the connection piping goes through the roof, washing room or other high temperature and high humidity
places, additional insulation material (optional) must be used to prevent condensation.
CAUTION
Do not let dirt moisture or other matter get in connection piping during installation
The bending radius of piping should be more than 100mm
It is better to use torque wrenches. Do not use adjustable wrenches. If you use a solid wrench, the
tightening torque can
be estimated as follows: when a flare nut is tightening with a spanner and the
tightening torque starts to increase r
apidly, stop temporarily, then turn through 60-90 angle.
If the pipe length is more than 3m, charge the system with additional refrigerant.
Draining P iping Work
In order to confirm that the waste water is drained out reliably, install the drain pipe so that it slopes downward
(Diagram 1)
Do not Install is as shown from (diagram 2) or Diagram 5)
(Diawing 1)
Remove the air in the indoor unit and piping
The air, moisture and other foreign matter in the indoor unit or piping may cause operation current overloading
and cause blocking of capillary tube. This leads to operation failure. Remove the air or moisture as follows:
Remove the caps from the service port of liquid stop
Sealing of the wall hole and fixing of the piping
1. Seal the gap between socket and wall hole using sealing compound
2. Fix the piping to the wall or pointed position with band.
If the drainage hose provide in the indoor unit is not long enough the drainage hose provided in the
accessories box can be joined together.
If the drain hose passes through an indoor area, bind it with tape together with the connection piping
(about its mounting requirements refer to p15)
