4 Operation
4.1 Commissioning
Commissioning of the cooling unit must be carried out by competent personnel
according to the commissioning procedure, see
EcoCooler, Commissioning record
, which is available to download from
.
The commissioning procedure applies to units that are supplied with control
equipment (code MX).
The validity of the product warranty is conditional on the system having been
commissioned correctly. Working on the cooling unit during the warranty period
without the approval of IV Produkt shall render the warranty void.
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.
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.
