2.1 Installing the device
The PHP device must be installed on a horizontal and solid
floor and it must be set up vertically by using the adjustable
stands (1). The four holes on side of the socket can be
used to transport the device (for example by inserting
2 pipes, max. 1”).
The implementation into the system return must be executed
acc. to the hydraulic diagrams in
Chapter 3 “Hydraulic
diagrams”.
PHP series devices can be used in plants with max.
temperature of 70 °C at the connection point. If the max.
temperature at the connection point exceeds 70 °C,
cooling vessels must be installed.
The implementation into the system return must be done
at a position where no external pressure can occur.
External pressures could affect the trouble-free operation
of the pressure maintenance device.

makeup module PHP EMCF-1 V
(Model EMCF-1 V included when
break tank fitted).
PHP series devices factory provided are delivered without
