Vacuuming And Charging - Acson CK20E Installationsanleitung

• All wires must be firmly connected.
• Make sure all the wire not touching the refrigerant piping, compressor or any moving parts of the fan motor.
• The connecting wire between the indoor unit and the outdoor unit must be clamped on the wire clamps.
• The power supply cord must be equivalent to H07RN-F (245 IEC65, 245 IEC66) which is the minimum requirement.
• When attaching the terminal box lid, make sure do not pinch any wires.
• After all the wiring connections are done, fill in any gaps/holes with insulation (procured locally) to prevent small animals
and insects entering the unit from outside.
• Use round crimp-style terminal for connecting wires to the power supply terminal block. Connect the wires by matching to
the indication on terminal block. (Refer to the wiring diagram attached on the unit).
Step to connect the installation wire:
• Used the correct screwdriver for tightening the terminal screws. If the block is too small, the mad of the screw might be
damaged and the screw will not be properly tightened. If tightening too hard, screw might be damaged.
• Do not connect wire at different gauge to the same proper supply terminal.
• Use specified electric wire. Connect the wire securely to the terminal. Lock the wire down without applying excessive
force to the terminal.
• Keep wiring in mat order and not to obstruct other equipment such as popping open the terminal box lid.

Vacuuming is necessary to eliminate all moisture and air from the system. The series II Outdoor Unit is provided with flare
valve fittings.
Vacuuming for indoor unit
Before vacuuming, perform leak check for refrigeration circuit. After the system piping are properly connected, connect the
flexible hoses to the correct charging nipples as shown in the diagram. Ensure that flexible hose from charging nipples are
connected to the vacuum pump via standard servicing valves and pressure gauges (gauge manifold). Vacuum the air conditioner
system to at least 500 microns Hg. Do not start the unit when the system is engaged in vacuuming. The outdoor is pre-charge.
