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
Nano Stainless Steel heaters with yellow enclosure (Incoloy 825 Heating
element) are
NOT
suitable for use on saline (salt) water pools.
Nano heaters with white enclosure (Titanium Heating element)
are suitable for use with salt water pools with a salt concentration
up to 8000ppm (8g/litre).
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.
The heater will only switch ‘On’ (red light indicator illuminated) when the
following criteria are met ie:
l Water circulating pump is ‘On’ delivering in excess of 1,000 litres /
hour (220 UK gallons/hour)
l Temperature set point dial is set to a higher value than that of the water
Q:
How long will it take to heat my pool?
A:
Assuming no heat losses, and a heater sized in the ratio 1.5-kW per 1,000
UK gallons of water (4,545-litres): it will take 2 days of continu-ous running
to raise the temperature of a pool from tap temperature to swimming
temperature. Heat loss will slow the heating process, particu-larly during
periods of cold weather, hence the higher the water tempera-ture is to be
maintained above average ambient air temperature, the slower the heating
process will become.
The only influencing factors are the level of insulation and the location of
the pool with regard to wind shelter.
