Instructions – Fuse Variants
1) Before working on this equipment, ensure that the device is fully isolated from any supply voltage, including connections to all relays and other
I/O connectors.
2) Open the Coldroom front panel by unscrewing the screw fixings at the top right and bottom right of the panel door. If an Isolator
switch is fitted to the Coldroom panel then this must be in the off position before the door will open.
3) Locate the Fused outputs.
4) Look at the PCB screen print to identify each output and the associated Fuse. Note the ratings of the Fuse are marked on each
Fuse and they should be checked to ensure the current Fuse rating is correct for the position in which the Fuse is fitted.
5) To swap the higher rated Defrost Fuse over with the Compressor/LLV Fuse firstly remove the rubber cover on each Defrost
and Compressor/LLV Fuse.
6) Now remove and swap the Fuse in position “F5 Defrost” to “F1 Compressor/LLSV” and the Fuse from “F1 Compressor/LLSV”
to “F5 Defrost”.
7) Ensure the Fuses are securely fitted and the desired rated Fuse is in the appropriate position.
8) Now reattached the rubber cover over each Fuse ensuring the fuse and holder is fully covered.
9) Close the Coldroom panel door and secure the front panel via the two screw fixings.
Warning : Only the Compressor/LLV and Defrost Fuse positions are interchangeable. No other Fuse positions can be altered.
