Flow direction
Fig 6.
The flow rate of water into the heater must not exceed 17,000 litres per
hour (17m3 / hour / 3,740 UK gallons per hour). A higher flow rate will
require the installation of a bypass to prevent damage to the heater
elements. The heater will not operate unless the following minimum flow
rates are achieved:
1,000 litres / hour (1m3/hour / 220 UK gallons/hour) for 2 ~ 6-kW heaters
4,000 litres / hour (4m3/hour / 880 UK gallons/hour) for 9 ~ 24-kW heaters
Water Quality
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— 1,000ppm
Stainless Steel heaters are NOT suitable for use on saline (salt) water pools.
ONLY
