GENERAL INSTALLATION INSTRUCTION
Mounting instruction
The heat exchanger can be either installed horizontally or vertically allowing
enough space for the pipe connections.
Caution : If the heat exchanger is unused during the winter months, it must be drained to prevent frost damage. Water must not be allowed to freeze in the heat exchanger, as this will cause severe damage.
Pipework
The heat exchanger should be installed at a low point in the filtration
system. It should be positioned downstream of (after) the filter and upstream
of (before) any dosing or other water treatment plan. (see Fig. 3).
Horizontal wall mounting
Your G2 Heat Exchanger should be connected to the two independent water circuits as follows:
Connection to Water Filtration Circuit (Secondary)
The Heat Exchanger should be plumbed in-line, after the filtration pump and
filter and before any water treatment equipment. It must be fed with clean
water. Weed/debris should not be allowed to enter the Heat Exchanger.
Universal 1.5” / 50mm ABS unions for connection to rigid PVC or ABS pipe are
included (stepped internal diameter to accommodate both sizes). The Heat
Exchanger should be installed as close as possible to the boiler/heat source
to minimize heat loss. To assist with correct air purging and to ensure that
the Heat Exchanger remains full of water during operation, it should be
installed at the lowest point in the filtration circuit. If the Heat
Exchanger is installed in a vertical plane, it is essential that the pool/pond
water (secondary circuit) enters low and exits high.
Connection to Heating or Cooling Circuit (Primary)
The Heat Exchanger should be connected directly to the primary circuit i.e.
boiler/chiller via the provided 1” BSP male brass connectors.
NOTE: The circulation pump of the primary circuit should be controlled by a thermostat, which should be connected via the filtration pump to allow heating only when the filtration pump is running.
Air bleed valves should be installed at the high points of the primary circuit. To ensure correct temperature detection, the thermostat/thermistor must be positioned at the pool/pond water inlet of the Heat Exchanger. The thermostat pocket and blanking cap use a common port and can thus be swapped as required.
- Care should be taken not to over-tighten any connections, as this could result in damage to the heat exchanger.
- Only use the supplied brass connectors as other uncertified connectors may leak or cause damage to the unit.
Circulation Direction
The primary and secondary circuits should be installed so water flows are
counter current i.e. The water from the primary circuit should flow in the
opposite direction to the water in the secondary circuit.
CAUTION:
If the Heat Exchanger is not used during the winter months, it must be drained
to prevent frost damage.
NOTE : For Winterising/maintenance, it is recommended that the Heat Exchanger is installed with isolation valves on both the water input and output sides of the primary and secondary circuits. This will allow the water to be shut off on both sides and aid removal from the system when required.
Water quality
To prevent damage to your heat exchanger, the water quality MUST be within the
following limits:
- PH : 6.8 – 8.0
- Total Alkalinity (TA): 80 – 140 ppm (parts per million)
- Chloride Content MAX: 150 mg/litre
- Free Chlorine: 2.0 mg/litre
- Total Bromine: Max 4.5 mg/litre
- Total Dissolved Solids (TDS)/Calcium hardness : 200 – 1,000 ppm
