Continuous product development may give rise to specification changes without notice.
4 Operation
4.1 Commissioning
Commissioning of the unit must be carried out by competent personnel accor-
ding to the commissioning procedure, see
ThermoCooler HP, Commissioning record
, which is available to download from
.
The validity of the product warranty is conditional on the system having been
commissioned correctly. Working on the unit during the warranty period without
the approval of IV Produkt shall render the warranty void.
The unit was designed and manufactured based on given operation cases
that must comply with the unit’s use for optimal function and a good operating
economy.
External circumstances should not be changed without checking that such
changes are within the unit’s intended area of operation.
NB!
It is important that the oil is warm inside the speed controlled compres-
sor crankcase before starting the cooling unit. The crankcase heating
must be switched on long enough before the unit begins operating so
that the oil maintains a temperature of at least 30 ºC. The maximum
warm-up time is approximately 2–3 hours. The temperature can be
measured externally at the bottom of the compressor.
NB!
For units in size 600-980 (2-circuit), the compressor for the second
circuit is dependent on the correct phase sequence. Compressor 2
starts briefly 30 seconds after powering up the unit in order to check
the phase sequence. Check whether the alarm is displayed.
If necessary, switch two of the incoming phases.
Prior to commissioning, the contractor must:
NB!
Wiring of connections and other electrical work may only be carried out
by a qualified electrician or by service personnel recommended by IV
Produkt.
1. Connect the unit to the power supply via a lockable safety switch.
2. Connect all ducts.
WARNING!
Rotating fan impeller. The unit must not be energised until all
ducts have been connected.
Follow the troubleshooting instructions in the troubleshooting chart before
contacting a service representative for servicing a unit under warranty. This will
prevent any unnecessary service calls.
