Before Start Up

Pool water must be 

fl

 owing through the heater and  the 

pressure gauge must be showing between 1.0 and 2.5 
bar for it to operate

Quick Start

Check that the electricity and gas supplies are 
turned on. Turn on the pool pump. Using the switch 
on the front facia turn on the heater. Adjust the pool 
temperature set point using the pool temperature 
control knob. Within a few seconds the heater will 
begin its ignition sequence.

 

Summary of Controls

 

(Left to Right)

 

Pressure Gauge - 

This should normally be between 

1.5 to 2.0 bar, re-pressurise if too low.

ON/OFF Switch - 

Turns the heater On and O

 .

Lock/Reset Button

 - 

If it is pressed for 2 seconds 

it locks the pool temperature setpoint so the pool 
temperature knob is inoperative. To unlock, press 
again for 2 seconds. When locked a short press 

fl

 ashes the set temperature.

It also resets gas control lockouts, GAS and OH2.

Pool Temperature Display

 - 

This normally shows 

the pool temperature but also shows the pool set 
point when the pool temperature control knob is 
rotated. The display is also used for commissioning 
and diagnostic purposes. (see 5.2 for details)

If the display alternates the temperature with ‘SEr’ it 
is recommended that the heater is serviced. In the 
mean time the heater will continue to function.
