Check After Installation - Vivax ACP-18CH50GEEI Service Manual

7.4.2 Air Purging and Leakage Test
1. Connect charging hose of manifold valve to charge end of low pressure valve
(both high/low pressure valves must be tightly shut).
2. Connect joint of charging hose to vacuum pump.
3. Fully open the handle of Lo manifold valve.
4. Open the vacuum pump for vacuumization. At the beginning, slightly loosen joint nut
of low pressure valve to check if there is air coming inside. (If noise of vacuum
pump has been changed, the reading of multimeter is 0) Then tighten the nut.
5. Keep vacuuming for more than 15mins and make sure the reading of multi-
5
meter is-1.0 X10 pa(-76cmHg).
6. Fully open high/low pressure valves.
7. Remove charging hose from charging end of low pressure valve.
8. Tighten lid of low pressure valve. (As shown in Fig.6)
7.4.3 Outdoor Condensate Drainage (only for heat pump type )
During heating operation, the condensate water and defrosting water should be
drained out reliably through the drain hose. Install the outdoor drain connector in
a Φ25 hole on the the base plate and attach the drain hose to the connector,so
that the waste water formed in the outdoor unit can be drained out .The hole diameter
25 must be plugged.
Whether to plug other holes will be determined by the dealers according to actual conditions.

7.5.1 Check after Installation

Has the unit been fixed firmly?
Have you done the refrigerant leakage test?
Is thermal insulation sufficient?
Is water drainage satisfactory ?
Is the voltage in accordance with the rated
voltage marked on the nameplate?
Is the electric wiring or piping
connection installed correctly and securely?
Has the unit been securely earthed?
Is the power cord specified?
Is the inlet or outlet blocked?
Is the length of connection pipes
and refrigerant capacity recorded?
