INSTALLATION.
PRIMARY
The primary inlet connection is made into the 3 port valve, whilst the outlet is from the
lower BSP threaded connection. Both primary connections should be made using the
correct counter flanges and suitable isolating valves, to enable servicing of the unit
after installation.
To ensure correct operation, water at the design flow temperature should be available
to the plate heat exchanger at all times. This is necessary because the plate heat
exchanger itself, under no load conditions, does not flow water through the boiler.
Consequently when a demand for hot water occurs the boiler would be unable to
respond fast enough to prevent temperatures dropping.
On systems with a sealed secondary circuit, operating with primary temperatures over
90
0
C, where a flow can persist even when the primary pump is switched off and/or
motorised valve is closed, by the inbuilt high limit, additional primary shut of valves
operated by a high limit thermostat may be required.
The “Typical installation schematic” shows an ideal example.
