Additional Refrigerant Charge
8.3
Refrigerant cannot be charged until field wiring has been
completed.
Refrigerant may only be charged after performing the leak
test and the vacuum pumping.
When charging a system, care shall be taken that its
maximum permissible charge is never exceeded, in view of
the danger of liquid hammer.
Charging with an unsuitable substance may cause
explosions and accidents, so always ensure that the
appropriate refrigerant is charged.
Refrigerant containers shall be opened slowly.
Always use protective gloves and protect your eyes when
charging refrigerant.
Using the vacuum pump
When the pumping has finished, close the Lo-lever of the
manifold valve completely and turn off the vacuum
pump.Make pumping for 15 minutes or more and check that
the compound meter indicates -76cmHg(-1X10 Pa)
Loosen and remove the cap of stop valves A and B to open
stop valve A and B completely, then fasten the cap.
Disassemble the charge hose from the service port of stop
valve A, and fasten the nut.

Drainage test
Drainage test
Install the drain joint of the outdoor unit
Check whether the drainpipe is unhindered.
New built house should have this test done before paving
the ceiling.
Remove the test cover, and stow water of about 2000ml to the
water receiver through the stow tube.
Turn on the power, and operate the air conditioner under the
"COOLING" mode. Listen to the sound of the drain pump.
Check whether the water is discharger well (a lag of 1min is
allowed before discharging, according to the length of the drain
pipe), and check whether water leaks from the joints.
1
2
Stop the air conditioner, turn off the power, and reset the test
cover to its original position.
3
Fit the seal into the drain joint, then insert the drain joint into the
base pan hole of outdoor, rotate 90° to securely assemble them.
Connect the drain joint with an extension drain hose (Locally
purchased), in case of the condensate draining off the outdoor
unit during the heating mode.
The drain plug is used to empty the water-receiver for
maintenance of the air conditioner. Please stuff it imposition at
all times during operation to avoid leakage.
The body's pump pipe and the drainpipe (especially the
indoor part) should be covered evenly with the out-let pipe
sheath (fittings) and be bound tightly with the constrictor to
prevent condensation caused by entered air.
To prevent water from flowing backwards into the air
conditioner while the air conditioner stops, please lean the
drainpipe down toward outdoor (outlet-side) at a degree of
over 1/ 50. And please avoid any bulge or water deposit.
Do not drag the drainpipe violently when connecting to
prevent the body from being pulled. Meanwhile, one
supportpoint should be set every 1~1.5m to prevent the
drainpipe from yielding.Or you can tie the drainpipe with the
connecting pipe to fix it.
In the case of prolonged drainpipe, you had better tighten its
indoor part with a protection tube to prevent it from loosing.
If the outlet of the drainpipe is higher than the body's pump
joint, the pipe should be arranged as vertically as possible.
And the lift distance must be less than 200mm, otherwise the
water will overflow when the air conditioner stops.
The end of the drainpipe should be over 50mm higher than
the ground or the bottom of the drainage chute, and do not
immerse it in water. If you discharge the water directly into
sewage, be sure to make a U-form aquaseal by bending the
pipe up to prevent the smelly gas entering the house through
the drain pipe.

9. CONNECT THE DRAIN PIPE
Install the drainpipe of the indoor unit
You can use a polyethylene tube as the drainpipe
(out-dia.37-39mm, in-dia.32mm). It could be bought at local
market or from your dealer.
Set the mouth of the drainpipe onto the root of the body's
pump-pipe, and clip the drainpipe and the out-let pipe sheath
(fittings) together firmly with the out-let pipe clasp (fitting).
The outdoor unit is factory charged with refrigerant. Some
systems require additional charging of refrigerant depending
on pipe lengths. The additional refrigerant to be charged
can be calculated from the following formule:
