Table 9- Standards steps to go through before starting the unit
Tick when
checked
1
Check for external damage
2
Install main fuses, earth leak detector and main switch. Recommended fuses: aM according to
IEC
standard

3
Supply the main voltage and check if it is within the allowable ±10% limits of the nameplate rating. The
electrical main power supply must be arranged so, that it can be switched on or off independently of the
electrical supply to other items of the plant and equipment in general. Refer to the wiring diagram, terminals
N,
L1, L2, L3 and PE.
4
Supply water to the evaporator and condenser and verify if waterflow is within the limits as given in the table
under “Water charge, flow and quality”.
5
The
piping must be completely purged. See also chapter “Checking the water circuit”.
6
Connect flowswitch and pump contacts, so that the unit can only come in operation when the water pumps
are running and the waterflow is sufficient. Make sure a water filter is installed.

Connect the field wiring pumps start-stop.
8
Connect the fiels wiring for remote control.
I do confirm having executed and checked all the above-mentioned items.
