TESTING (MUST BE COMPLETED BY QUALIFIED PERSONNEL)
1. Double check that all plumbing is connected correctly and that the supply is
available for heater and control box.
2. Before switch on check that gate valves (if fitted) are open and the thermostat is
turned fully anti clockwise.
3. The heater lid should be off for setting up pressure switch adjustment.
4. Apply a voltmeter, neon indicator or such test device at element terminal or
control relay. If preferred, a current meter could be used.
5. Apply power. There should be no indication that the element is alive.
6. Start pump and check for water leaks, paying particular attention to the join
between heating head and body.
7. After checking the system is free of plumbing problems, allowing sufficient time
for all air to be purged, advance the thermostat setting to full on.
8. The test device should now indicate heating. Turning the thermostat control
through its full range should switch test indicators on and off.
9. Leave the thermostat setting at the fully clockwise position so the test indicator
is active and stop the pump. The indicator should switch off almost immediately.
If it fails to switch off restart pump quickly and adjust the screw on the pressure
switch clockwise until heating stops. Adjust back until heating restarts and then
one further full turn.
Stop/start pump several times until you are happy that
the heating is switching on and off consistent with the pump running.
REFER FIG 1.
N.B. If the heater is fitted to a portable pool or the equipment is
mounted at about the same level as the pool water the pressure
switch will probably not require adjustment. CHECK IT ANYWAY.
It the equipment is mounted nelow the level of the pool water
the static water pressure could be enough to hold the heating
on after the pump stops. It is important for safety that this
condition does not occur. FAILURE TO SET THE PRESSURE
SWITCH CORRECTLY WILL VOID THE WARRANTY.
