POOL WATER PIPE CONNECTIONS
The Heatstar requires connection into the pool water filtration pipe work :
POOL WATER FLOW SPECIFICATIONS :
The required pool water flow rates and resistance through the Heatstar are detailed in the data contained within
the
‘Installation Services’ document supplied with the product, further copy available on request.
PIPE WORK CONNECTIONS :
The inlet and outlet to the Heatstar are connected via the return line going back to the pool i.e. after the pump
and filter and before the chemical dosing.
The pool water inlet and outlet connections on the Heatstar are marked and must be connected as indicated.
The Heatstar has PVC stub connections suitable for solvent welds.
The Heatstar should be connected via unscrewable couplings.
It is suggested that the connection of the Heatstar is the last to be made in the pool water circuitry to prevent
damage to the pipe stub connections on the Heatstar.
ROUTING OF PIPE WORK :
Do not route pipe work across the service access panels of the Heatstar or the air filter access point.
All pipe work must be adequately supported for the operating weight when full of water with allowance made for
expansion and contraction.
POOL WATER BY-PASS :
A by-pass facility with isolation valves should be installed on the connections to the Heatstar. This will enable the
pool filtration system to be operated normally in the unlikely event of a leak within the Heatstar.
If any valve positioned after the Heatstar is closed whilst the pool water circulating pump is still running, the
increase in pressure may damage the Heatstar. It is therefore recommended that the handles be removed from
such valves and placed inside the access panel of the Heatstar.
CHEMICAL DOSING :
All purification devices and chemical injection systems must be fitted DOWN STREAM of the Heatstar.
If they are before the Heatstar in the line of flow, then serious corrosion damage may occur to the Heatstar.
This includes the practice of dosing slow dissolving tablets via the skimmer or pump basket, which can result in
concentrated corrosive liquids passing over metal components within the Heatstar.
This relates to any slow dissolving tablets of ANY description, whether chlorine based or not.
Please note that the installation and usage instructions for the chemical dosing equipment often recommend that
the chemical is introduced before the pool water filter. This should NOT be done unless the Heatstar is installed
on a completely separate pipe circuit fed from an additional pool water pump.
NON-RETURN VALVE :
If, when the pool water filtration pump is switched off or if the pool water pipe circuit is drained, chemicals
introduced into the filtration system can be drawn through the Heatstar, a non-return valve must be fitted.
