Pressurisation Equipment

Installation
This pressurisation unit is not designed to be installed in an outdoor environment. The unit must be
installed in a frost free environment, away from precipitation and water sprays/jets. If there is a risk of
flooding, the unit must be installed on a raised plinth.
The unit is equipped with a Category 5 Weir overflow arrangement and must not be installed / sited
where damage to the local environs can occur on water egress
Please refer to the appropriate datasheet for the maximum working pressure and temperature of the
pressurisation unit. The conditions at the point of connection to the system must not exceed these
values.
Pipe Connections
To avoid damaging the float valve, the mains water supply pipe must be flushed before connection to
the pressurisation unit.
All pipe connections must be made with appropriate jointing compound/PTFE tape. If PTFE tape is
used, care must be taken to ensure that the tape does not obstruct the orifice of the fitting.
Non-return valves, pressure reducing valves and RPZ valves must not be installed between the
pressurisation unit and the heating/cooling system. These devices will prevent the pressure sensor
from reading the system pressure.
The pressurisation unit and expansion vessel should be connected to the system at the same point,
to provide a neutral pressure reading. This point of connection should be in the system return, on the
suction side of the circulation pump.

Connections to the return header of the system must be made in the horizontal plane, to prevent
system borne debris entering the equipment. Where 2 connections are required to the system
return header, they must join the header at 2 distinctly separate points at least 500 mm apart
