Revision: 03
Date: 25/10/2024
Applicable to: E4
Change over date: 25th October 2024 (Serial number 2410**)
Please note, the 230V Compressor Control Board (CCB) fuse has been changed from T2A to T3.15A as of 25/10/24.
This change affects production units’ serial numbers 2410 and onwards.
To identify if a T3.15A fuse has been fitted to the CCB, a label has been added to the rear of the unit and the outer carton packaging:
In some instances, it may be necessary to insert an uprated fuse into the recently distributed E4 Compressor Control Board. The standard 2amp fuse is suitable for regular use and has passed all necessary safety and regulatory tests, even in accelerated wear conditions. However, in rare cases where external factors such as:
- Regulated power supplies
- Unusually heavy use or tough environments (e.g., dusty factories or high-temperature areas)
- High incoming water temperatures
- Circuits prone to power surges
- At present, we recommend using a 3.15A slow-blow fuse in the Compressor Control Board.
If the 2amp fuse does fail, the unit will continue to dispense ambient and hot water safely with absolutely no risk to the user. There is no need to replace all the fuses in all units as in most cases the 2amp fuse will be perfectly adequate. Only where necessary, simply insert a 3.15A slow-blow fuse, which we are providing free of charge (FOC), as needed.
