3. Additional charge

3.1. When the length of the one-way pipe is less than 5m, additional refrigerant charge after vacuuming is
unnecessary.
3.2. When the length of one-way pipe is over 5m, the additional charge quantity is as follows (unit in gram):
Calculation method
Refrigerant
R410A
Remark 1 The additional refrigerant charge is simply related with the liquid pipe diameter.

4. Water drainage

4.1. Gradient and Supporting

4.1.1 Keep the drainpipe sloping downwards at a gradient of at least 1/100. Keep the drainpipe as short as
possible and eliminate the air bubble.
4.1.2 The horizontal drainpipe should be short. When the pipe is too long, a prop stand must be installed to
keep the gradient of 1/100 and prevent bending. Refer to the following table for the specification of the prop
stand.
