Checking the control board fuses, and replacing the board
There are two relays and fuses located in the control board. These control the compressor and
electrical heater. If these are not working, you should check the fuses and relays. The control board
may also need replacing.
1.
Firstly, check that the power is turned off to the system.
2.
The white cowling cover will have to be removed from the side of the cylinder to gain access
to the compressor unit. This has two screws, one each side.

The controller board is located at the bottom of the compressor unit under a black plastic
cover, hanging under the right-hand corner of the metal frame that the compressor sits on.
4.
There is one screw at the top centre holding the black plastic cover in place over the
controller, remove the screw and gently slid the black cover down. Do not use excessive
force.
5.
The fuses are located in the two black cylinders. Use a screwdriver to push, twist and release
the fuse. The fuses are 10A, 5x20mm normal blow. There are are spare fuses taped to the
inside of the compressor cover.
6.
The main power supply wiring needs to be unscrewed with a screwdriver, but all the other
connections can be unplugged.
7.
Note that the plugs for the COMP and RES are interchangeable. The plug with the orange
and yellow wires goes in the left hand ‘COMP’ port, while the plug with the
blue and brown
wires go into the right hand ‘RES’ port.

There is one screw in the bottom left corner of the board to hold the controller in place.
