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 brass connectors, see
diagram below.
NOTE: The circulation pump of the primary circuit should be
controlled by a thermostat, which should be connected via the
ltration pump to allow heating only when the ltration 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. The thermostat pocket and ow switch use a common port,
and can thus be swapped as required.
Use two wrenches to fasten ttings.
Wrench No. 1 should remain steady. NOTE: The Thermostat Control is
only included with the ’Optional’
fully equipped kit. The standard
unit is supplied only with a
Thermostat pocket and blanking
cap.
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 uncertied
connectors may leak or cause
damage to the unit.
