Water Quality - Elecro EVO Manual Del Usuario

The flow rate of water into the heater must not exceed 17,000 litres per
hour (3,740 UK gallons/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 ie:
1,000 litres / hour (220 UK gallons/hour) for 2 ~ 6-kW heaters and
4,000 litres / 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 heaters with titanium heating elements are suitable for use on saline
(salt) pools.
Water chemistry is complicated if in doubt seek expert advise.
Operating Instructions
Upon completion of the installation, run the water-circulating pump to
purge the system & heater of air (i.e. Remove any trapped air in the
system & heater). TIP: You can encourage air out of the heater flow tube by
gently elevating the exit port of the heater when the pump is running.
On initial power up of the heater the amber light should illuminate.
The heater will only switch 'On' (red light indicator illuminated) and the
amber light switching 'Off' when the following criteria are met ie:
• Water circulating pump is 'On' delivering in excess of the minimum flow
rate of water (see flow requirement information)
• Temperature set point dial is set to a higher value than that of the water
