On the Electrical Chassis
To access these items first remove the Front Top
Panel and then the Chassis Cover.
Fuse
( See Fig. 13.0 )
There is one inline 3A fuse on the 24V supply be-
tween the Transformer and the Pool Thermostat. The
Fuse Holder bayonets apart to allow its replacement.
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
Transformer.
 Disconnect from the terminal strip and fuse
holder.
 Undo the two screws holding it to the chassis and
replace.
Pool Thermostat
(
See Fig. 13.0
)
 Pull off the Pool Thermostat Knob.
 Release the Rear Retainer by undoing the Wing
Nut.
 Pull off all the PCB connectors.
 Slide out the Thermostat.
 Replacement is the reverse.
Condensate Pressure Switch
(See Fig. 13.0 )
 Undo the single fixing screw.
 Pull off the two electrical connectors and transfer
to the new Switch. They connect to the ‘C’ and
‘NO’ connections.
 Replacement is the reverse
Relay
(See Fig. 13.0 )
 Pull off the three electrical connectors and
transfer to the new Relay.
 Undo the two fixing nuts and secure new relay in
position.
Heater Components
The remainder of the parts can be accessed
through the front.
Heat Exchanger Flow Sensor
This is located on the front connection to the Heat
Exchanger. (
See Fig.14.4 )
Condensing Pool Heater
26
22/12/08
 Unclip the sensor from the connection.
 Transfer the push on electrical connectors to the
replacement and clip back on.
Heat Exchanger Pool Sensor
This is located in a pocket in the ‘From Pool’ side of
the Secondary Heat Exchanger.
( See Fig.14.6)
 Pull out the retaining slipper, and pull out sensor.

Diisconnect from the six way terminal strip on the
Electrical Chassis.
 Replacement is the reverse.
Water Pressure Switch
This is located on the Inlet connection to the Second-
ary 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
Exchanger. (
See Fig.14.4 )
 Unclip the sensor from the connection.
 Transfer the push on electrical connectors to the
replacement and clip back on.
Heat Exchanger Combustion
Temperature Sensor
This is located on the top of the Heat Exchanger, on
the right hand side. (
See Fig.14.1 )
 Release the electrical connector by pressing the
latch and pulling up.
 Twist the Sensor a quarter turn clockwise and
withdraw.
IMPORTANT Ensure the O ring seal is fitted correctly
to the replacement before fitting.
 Replacement is the reverse.
Flue Thermostat (manual reset)
This is located on the Flue Adapter. ( See Fig.14.1 ).
 Pull off the electrical connectors.
 Slide out from under the clip.
 Replacement is the reverse.
Ignition Control
( See Fig.14.3 )
 Undo the single screw holding the Ignition Control.
 Release the two electrical connectors by pressing
the latch and pulling apart.
 Pull the Ignition Control away from the Gas Valve.
 Replacement is the reverse.
