1. Test for earth continuity. This test is to verify that in no instance should the resistance between the earth
conductor (or control panel main earth terminals) and the metal parts exceed 0.1 ohm.
The electrician MUST ensure that the resistance in the earth conductor between the mains incoming supply and
our control panel earth terminal does NOT exceed the figure quoted above. It is also the responsibility of the
electrician to ensure that the earth conductor into our control panel is sized in accordance with the latest edition of
I.E.E. regulations.
A current of 25 amps should be passed between the control panel main earth terminal and all exposed metal parts
in turn. The test shall be made at a voltage not exceeding 6v ac.
Small isolated metal parts on, in or through non-conducting material, and separated by such material from current
carrying parts in such a way they cannot become live, should not be included in the test.
2. A test of polarity should be made and it should be verified that all fuses and single pole control devices are
connected in the phase conductor only.
13.3 Evacuation
Before startarting the vacuum procedure it is necessary to open by hand the high pressure valve (HPV), see
section 11 above. Also you can refer to P&ID attached in this maunal. For this operation the magnetic tool shown
below needs to be used.
CAREL Product Reference & name: EEVMAG000 Valve actuator
The operator can stop the vacuum procedure when the standing vacuum pressure (SVP) reaches 0.5 Torr.
13.4 Charging Refrigerant into the System
Initial charging should only be completed once the system has been proven to be leak free and after proper
vacuum. The charging point is located on the liquid line adjacent to the drier assembly. Liquid or gas should not be
added through the low pressure side of the system. Break vaccum with ONLY CO2 vapour (vapour off take
cylinder) up to 8 to 10 bar pressure. By using vapour CO2 up to that pressure you can avoid any dry-ice formation.
Make sure that compressor is off during this operation.
Maximum amount of refrigerant can be found in section 16.
