4 Operation
4.1 Commissioning rules
Commissioning may only be carried out by skilled personnel and according to
the following check list and commissioning record (supplied with the cooling
unit). A copy of the commissioning record, after being signed by the person who
commissioned the unit, must also be signed by the seller before it is sent to the
IV Produkt Ordering Department.
The validity of the product warranty is conditional on the system having been
correctly commissioned. No modifications to the cooling unit may be made dur-
ing the warranty period without the approval of IV Produkt.
Follow the troubleshooting instructions in the troubleshooting chart before con-
tacting a service representative for servicing a unit under warranty. This will pre-
vent any unnecessary service calls.
4.2 Check list for commissioning cooling unit
The cooling unit must not be put into operation until all the items in the check list
have been checked off.
1. Visually inspect the cooling unit for damage after transport and as-
sembly.
2. Check that the cooling unit is correctly positioned and that the open
space in front of the unit for servicing is sufficient (1.5 x depth of the
unit, min. 1200 mm).
For more information, see the separate assembly instructions for each
unit series.
3. Check that the drain connection (evaporation water drainage) is con-
nected to a floor drain via a separate water trap. Check that the drain-
age pipe slopes correctly to the drain. For more information, see the
separate assembly instructions for each unit series.
4. Check that the incoming supply voltage, zero and earth are connect-
ed (see Section 3).
5. Check that control cables are connected (see chapter 3).
6.
Check that the automatic circuit breakers are set to the ON position
and switch on the voltage.
7. It is important that the oil is warm inside the speed controlled com-
pressor crankcase before starting the cooling unit. The crankcase
heating must be switched on long enough before the unit begins op-
erating so that the oil maintains a temperature of at least 30ºC. The
maximum warm-up time is approximately 2–3 hours. The temperature
can be measured externally at the bottom of the compressor.
8. Start the air handling unit (supply and extract air fans).
9. Check that there are supply and extract air flows and that they have
been adjusted and recorded.
