Connect the flow and return water circuit pipe work by means of the 15mm stubs which are
provided on the side of the machine. The connections project 40mm out from the left hand side
of the DH44 and the right hand side of th DH66.
Attention! Flow - bottom connection

The 3 way, motorised, diverting valve fitted to machines with the LPHW option is operated by a
remote 12V AC air temperature thermostat (available from Calorex).
When the valve is energised the flow is through the LPHW coil.
When the valve is unenergised the flow is diverted.
NOTE :- When the fan switch is set to cycle and the fan is not running, a demand on the LPHW
valve will cause the fan to automatically start.
