IV. 6.10. Additional Refrigerant Charge
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.
!
CAUTION
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.
■ The outdoor unit is factory charged with refrigerant R410A. Calculate the added refrigerant according to the diameter
and the length of the liquid side pipe of the outdoor unit/indoor unit connection.
R (g)
No added refrigerant R(g) when L(m) is length less than 5m (one-way)
Added refrigerant when the pipe length L(m) is over 5m (one-way)
R(g): Additional refrigerant to be charged
L(m): The length of the refrigerant pipe (one-way)
D(mm): Liquid side piping diameter

NOTE: If a negative result is gotten for R from the formula at right, no refrigerant needs to be added nor removed.
IV. 6.11.. Connect the drain pipe
■ Install the drainpipe of the indoor unit
● You can use a polyethylene tube as the drainpipe (out-dia.29-31mm, in-dia.25mm). It could be bought at local market or
from your dealer.
● 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 support
point 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.
The lift distance must be less than 200mm, otherwise the water will overflow when the air conditioner stops.(Only
available for the unit with pump.)
