ELECTRICAL CONNECTIONS
WARNING! – ALL ELECTRICAL WORKS MUST BE COMPLETED BY A LICENSED ELECTRICIAN
DANGER! This heater may be coupled to two sources of 240V AC power. Isolate all power sources prior to commencing any
installation, service, or other work. See also warnings included on the heater.
POWER CONNECTION(S)
The heater includes a loosely coiled 3-pin 240VAC power lead for connection to a mains power 10A GPO. This connection is
required for operation of the heater.
The heater should be properly connected to a GPO that is suitable for either indoor or outdoor use. Prior to connection inspect the
supplied power connection lead for any damage.
DO NOT connect the heater to any power source if there is any sign of damage.
For models 200, 280, 350, and 430 a second 3-pin 240VAC power lead is connected to the underside of your heaters control panel,
inside the door.
This power lead is included for use when a filtration system pump is to be connected to the heater for control by both the heater
and the filtration system.
Where two 240VAC connections are to be made it must be ensured that both operate of the same supply phase.
PUMP CONNECTION
Models: 200, 280, 350, 430 Only
The above model pool heaters are fitted standard with a 240V AC power socket to enable connection of a pool/spa circulation
pump. In most circumstances this pump will be the system pump, required also for filtration and would normally be connected to a
filtration system time clock.
To enable operation of the pump via the heater controller the pump must be connected to the heater power socket located inside
the heater cabinet on the underside of the controller housing. This is accessed by removing the front door of the heater.
If the pump is required to operate with the filtration system (as is normally the case), the additional lead included with the heater
(coiled inside heater cabinet) must be connected to the pump power outlet located on the filtration system time clock controller. If
this connection is not made the pump will fail to operate the filtration system correctly. If the pump is not required to operate in
conjunction with the filtration system it is possible to connect the additional 3-pin lead and plug included with the heater to a
suitable GPO. This GPO should normally be left in the “off “position. Switching the GPO “on” will override and heater control of the
pump and power the pump directly from the GPO.
Once the correct pump power connection is made, the pump will operate as per the approximate time periods of the following table.
Condition Period
At start up
3 mins
At shut down (when heating) 5 mins
Each 30 min’s from switching on. 3 mins
In spa mode Continuous
In pool mode and below temp. Continuous
Filtration operating Continuous
Filtration in manual operation Continuous
In Auto mode Program
In the connection diagram shown, power supply to the pump will be provided under normal conditions by the Filtration Controller.
Failure to connect the pump via the Filtration Controller will in most cases cause the filtration system to operate incorrectly.
It is also possible to connect a non filtration system pump to the heater. This is done by leaving the labelled power lead inside the
heater coiled and unused. This will enable manual operation of the pump as required.
