Boiler water :
To test the internal boiler pipe work, with the boiler water circulating pump running :
-
Open all internal motorised heating valves manually using the levers on the ends of the valves. This will
allow boiler water to flow through all of the boiler pipe work.
-
Check the internal air vent on the L.T.H.W. air heating coil has not been left open.
-
Observe for any other signs of moisture.
Pool water :
To test the internal pool water pipe work, with the pool water circulating pump running :
-
Observe for any signs of moisture.
If a leak is apparent within the Heatstar, please contact Heatstar for advice.
If installed correctly, it should be possible to isolate the Heatstar from the pool water circuit using the by-pass
valves, enabling the filtration circuit to function normally.
With a new installation it should be noted that, during commissioning, it may be necessary to tighten the internal
connection nuts on the heating valves and the internal connection unions on the pool water heat exchanger. This
is due to normal expansion / contraction as the operating temperatures rise.
AIR TEMPERATURE PROBLEMS :
The heating of the pool room air is a very simple process :
The heated boiler water is circulated through a
‘car radiator’ type coil within the Heatstar. The pool room air is
blown through this coil, picking up heat as it does so.
The flow of hot boiler water into the heating coil is controlled by an electric valve:
When the valve is closed, no hot water from the boiler is allowed to enter the air heating coil, therefore air
heating will be
‘off’.
When the valve is electrically opened, hot water from the boiler is allowed to enter the air heating coil, therefore
air heating will be
‘on’.
The valve is electrically opened by the
‘AIR TEMPERATURE’ control which is a THERMOSTAT which measures
the pool room air temperature. If the pool room air temperature is colder than the setting on the thermostat, then
the electric heating valve will be switched
‘on’ and it will be motored open.
For
‘Super Elec’ or ‘Super Plus Elec’ versions, see dedicated notes on all electric heating models.
When the AIR TEMPERATURE
’ control believes that air heating is required, the corresponding green neon will
be lit.
