Water Quality - Elecro Engineering In-Line + Swimming Pool Heater Installation Instructions & Operating Manual

F R
LOW EQUIREMENTS
Your heater is factory set to accept input water flow entering on the left and exiting on the right,
this can be reversed by rotating the flow switch 180° (i.e. ½ turn) (see diagram below).
Warning!
The flow switch paddle can be damaged when reversing the flow direction if it is lifted by more
than 5-mm from its housing and turned with force. If the flow switch has been rotated it is
important to ensure that it is finally locked in the correct orientation perpendicular (at right
angles) to the flow of water.
The flow rate of water entering the heater must not exceed 17,000-litres per hour (3,740 UK
gallons per hour). A higher flow rate will require the installation of a by-pass to prevent damage
to the element(s).
The heater will not operate with a flow rate of less than 1,000-litres per hour (220 UK gallons per
hour).
W Q
ATER UALITY
The water quality must be within the following limits:
PH 6.8-8.0
TA (Total Alkalinity) 80 - 140ppm (parts per million)
Chloride Content MAX: 150-mg/litre
Free Chlorine: 2.0-mg/litre
Total Bromine MAX: 4.5-mg/litre
TDS (Total Dissolved Solids) / Calcium hardness 200 - 1000ppm (parts per million)
Stainless steel heaters are NOT Suitable for use on saline (salt) water pools.
Only heaters with Pure Titanium Flow Tube And Pure Titanium elements are suitable for use on
saline (salt) water pools.
Water chemistry is complicated if in doubt seek expert advise.
