2. Connection to Heating or Cooling Circuit (Primary)
The heat exchanger should be connected directly to the primary heating
circuit i.e. boiler, via the provided 1" BSP male connectors, see diagram
below.
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, it is essential that
the thermostat / thermistor is positioned at the water inlet of the heat
exchanger.
NOTE: The Thermostat Control is only included with the 'Optional'
fully equipped kit. The standard unit is supplied only with a
Thermostat pocket.
Care should be taken not to over tighten any connections, as this could
result in damage to the heat exchanger.

Circulation direction:
The primary and secondary circuits should be installed so water flows are
counter current i.e. The hot water from the primary circuit should flow in
the opposite direction to the water in the secondary circuit.
