Lifting Method; Drain Piping; Refrigerant Charge - Acson ART 55 A Technical Manual

3. Lifting Method.

When the unit is to be lifted and moved, attach ropes to the hoisting
hangers (4 pieces) provided on the top corners of the unit.
When the unit is lifted, its center of gravity tends to shift the unit to
one side. Imbalance such as that in the figure should be attained.
The angles at which the ropes suspend the unit should be at
least 60º at the compressor end and at least 45º at the condenser
end. Care should be taken to avoid contact with the unit while it is
being lifted.

4. Drain Piping.

(1) The condensate drain fitting (R1) is provided. The drain pipe can
be led out at the right or left side. Please see Chapter 10:
Outlines & Dimensions for further details.
(2) The drain pipe must be provided with a trap on the outside of
the unit and also installed at an incline for proper drainage, as
shown below.
(3) To prevent condensate formation and leakage, provide the drain
pipe with insulation to safeguard against sweating.
(4) Upon completion of the piping work, check that there is no
leakage and that the water drains off properly.

5. Refrigerant Charge

An additional charge is unnecessary.
The table below shows the amount of the charge when the unit is shipped from the factory.
