Davey POOL AND SPA GAS HEATERS - Manual (Page 10)

Part No: 96131430D 10 Rev: 2
RESET BUTTON
Your Davey pool or spa heater has been fitted with an additional safety feature and weather shielding.
The additional safety feature incorporates a red reset button located on either the front control panel or right hand side panel,
together with a power failure recovery circuit.
When power is first supplied to the heater, or restored after being interrupted or isolated, the red reset button will illuminate briefly
before the power failure recovery circuit operates. To operate the heater when power is first supplied or restored after being
interrupted or isolated:
1. The red reset light should go out and the control panel should display “OFF”. If the light does not go out, the heater must
be serviced by a qualified service technician.
2. Press and release the POWER button on the control panel. The control panel will display the current water temperature.
3. If power is being supplied for the first time the internal time clock will need to be set. This may also apply if power has
been interrupted or isolated for some time and then restored. To reset the heater’s internal time clock follow the procedure
‘Setting Time & Day’ located on page 9 of the Installation and Operating Instructions.
4. If power is being supplied for the first time any required auto mode time periods will need to be programmed. If power has
been interrupted or isolated and then restored, any auto mode time periods previously programmed may need to be
reprogrammed.
To program auto mode time periods follow the ‘Programming Mode’ procedure located on page 14 of the Installation and Operating
Instructions.
The heater can now be operated as normal.
If during operation the heater stops working and the red reset button illuminates, check the following:
1. Ensure skimmer box is not jammed and that the filter is not blocked.
2. Ensure all valves are in the correct position and that there is adequate water flow through the heater.
If these conditions are checked and found to be satisfactory and the red reset button cannot be reset and/or continues to be
illuminated; the heater must be attended by a qualified service technician. For service Ph 131031
WATER – PRESSURE, CONNECTIONS, & FLOW
Pressure Relief Valve
If the filtration system incorporates any valves or accessories that may isolate the heater from the pool or spa, a pressure relief
valve must be fitted to the heater. Specifications and installation advice relating to this valve can be obtained from Davey.
Pressure Switch Function
The heater is supplied standard with a Pressure Switch that when correctly adjusted will only allow the heater to operate when
there is sufficient water pressure. In every installation the Pressure Switch operation must be checked as part of the
commissioning process.
Caution! The Pressure Switch is only suitable as a means of ensuring adequate water pressure if the Inlet/Outlet piping of the
heater is less than 1500 mm above or below the water level of the pool. For installations which exceed this range a flow switch
must be installed. Specifications and installation advice relating to this switch can be obtained from Davey.
Pressure Switch Adjustment
Models: 131, P0200- 430 .

3. Start the system pump and ensure that water is flowing through the heater.
4. Turn the power on at the heater.
5. Adjust the set point of the heater to 40ºC.
6. If the heater lights the water pressure is within the pressure switch range and the pressure switch will not need to be adjusted.
7. If the heater did not light after Step 6, turn the Pressure Switch knurled adjustment wheel located on the pressure switch,
clockwise until the heater ignites, then continue a further ¼ of a turn.
