On the Electrical Chassis
To access these items fi rst remove the Front Top
Panel and then the Chassis Cover.
Fuse (See Fig. 13.0)
There is one in line 3A fuse on the 24V supply
between the Transformer and the Pool Thermostat.
The Fuse Holder bayonets apart to allow its replace-
ment.
Transformer (See Fig. 13.0)
The Transformer includes its own, internal thermal
fuse on the primary. If this has gone open circuit the
cause should be established before replacing the

• Slide out the thermostat.
• Replacement is the reverse.
Condensate Pressure Switch
(See Fig. 13.0)
• Undo the single fi xing screw.
• Pull off the two electrical connectors and transfer
to the new switch. They connect to the ‘C’ and
‘NC’ connections.
• Replacement is the reverse

Water Pressure Switch
This is located on the Inlet connection to the secondary
heat exchanger and its removal will require the draining or
isolation of the pool water in the heater. (See Fig.14.6)
• Pull off the electrical connectors
• Unscrew from the secondary heat exchanger.
• Replacement is the reverse.
• If the water pressure switch needs adjustment See
Page 12 for details.
Control Thermostat
This is located on the outlet connection of the heat ex-
changer. (See Fig.14.4)
• Un-clip the sensor from the connection.
• Transfer the push on electrical connectors to the
replacement and clip back on.
