Additional Refrigerant Charge
7.2
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.
NOTE
CAUTION
If a negative result is gotten for R from Table 7-4, no
refrigerant needs to be added nor removed.
Additional refrigerant will be twice of R from Table 7-4 if
the indoor unit installed throttle assembly.
Outdoor unit is equiped with a drain piping. Its position is
shown figure below.
The outdoor unit is factory charged with refrigerant. Calculate
the added refrigerant according to the diameter and the
length of the liquid side pipe of the outdoor unit/indoor unit
connection.
Refrigerant containers shall be opened slowly.
Always use protective gloves and protect your eyes when
charging refrigerant.

8. 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 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 heat pump
while the heat pump 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. ( Refer to Fig.5-17.a
in the figure page)
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 (Refer to Fig.5-17a in the figure page).
Or you can tie the drainpipe with the connecting pipe to fix
it.(Refer to Fig.5-17.c in the figure page)
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 heat pump stops. (Refer to
Fig.5-18 in the figure page)
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.
Drainage testDrainage test
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. ( Refer to Fig.5-18 in the
figure page)
Turn on the power, and operate the heat pump 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 heat pump, turn off the power, and reset the test cover
to its original position.
3
The drain plug is used to empty the water-receiver for
maintenance of the heat pump. Please stuff it imposition
at all times during operation to avoid leakage.
NOTE
Install the drain joint of the outdoor unit
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.
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.
