It is permissible to fi t an isolating valves on the pipe-
work on either side of the heater. In these circum-
stances it is recommended to fi t a fl ow switch in the
heaters mains supply.
2.16 ELECTRICITY SUPPLY
Wiring external to the appliance MUST be in accord-
ance with the current I.E.T. Wiring Regulations and
any Local Regulations that apply.
This heater is supplied with a plug and lead for 230V
~ 50Hz. Single phase. Fuse rating is 5A.
The method of connection to the mains electricity
supply MUST facilitate complete electrical isola-
tion of the heater, preferably by the use of a fused
double pole switch having a 3mm (1/8in.) contact
separation in both poles and servicing only the
heater and its controls.
The point of connection to the mains should be
readily accessible and adjacent to the heater.
2.14 CONDENSATE DRAIN
(see 3.9 for details)
A 75mm condensate trap is provided on this heater
and is satisfactory when connected to soakaways,
gullies, rainwater pipework and internal drainage
systems. All pipework and fi ttings in the condensate
drainage system MUST be made of plastic, unless
they carry other liquid waste.
No other materials
may be used.
The pipework should be insulated if
run out of doors.
The drain outlet on the boiler is :
40 mm Hunter waste pipe.
2.15 POOL PUMP & PIPE WORK
This heater is an indirect design and uses two very
high performance heat exchangers. The pool water
passes through the secondary, the water in the
primary is completely separate. This heaters con-
trols modulate the input when approaching the set
temperature for greater accuracy and economy. It
is recommended that pool pump overrun is used to
maximise the life of this heater.
If a new pump is being fi tted consult the pressure
loss graph (
Fig 2.0
) to determine its size. This
heater is provided with 1½” plastic pool connections.
As built the connections are ‘From Pool’ on the left,
‘To Pool’ on the right, however these can be easily
reversed.
With the exception of automatic dosing equipment,
this heater should be plumbed as the last piece of
equipment before the pool.
