Below is an overview of how the settings on a pressurisation unit must be considered for normal operation.
Close, conflicting or overlapping settings will cause system instability and nuisance alarm conditions. If in any
doubt please seek advice from a Sealed System professional.
A typical venting allowance is 0.3 bar, added to the static height to give the cold fill pressure.
The Differential setting represents the allowable pressure loss before the pump activates and restores the cold
fill pressure. The Differential setting must not be greater than the system venting allowance. This will ensure
that the system remains fully flooded during normal topup conditions.

Pressurisation Equipment

Equipment Overview
The function of this pressurisation unit is to provide a means of automated water top-up to sealed heating and
cooling systems. The equipment is designed to provide periodic water top-up to compensate for minor losses in
system pressure (e.g. slow leaks, air venting, etc.).
This equipment is not designed to cope with sudden losses of system pressure (e.g. manual draining)
or major water losses (e.g. large leaks). The equipment is also not intended to be used for water
boosting applications.
Principal of Operation
The following schematic shows the internal arrangement of a pressurisation unit:
The ProDose unit is fitted with a break tank (1) which is filled from the mains water supply (2) via a float operated
valve (3). The break tank is fitted with an overflow (4) in case the break tank overfills, and a weir overflow (5) in
case the primary overflow fails. Also fitted is an additive tank (14). Additive tank is filled with either Ethylene or
Propylene-Glycol, to add to the system a required mixture is required. To do these two balancing valves are placed
after each of the tanks to control the mixture water (12) and Additive (13). (See Balancing valve settings table)
The pressurisation unit is connected into the heating system (6) via an isolation valve (7).
The pressure sensor (8) monitors the system pressure.
If the pressure sensor detects a drop-in pressure, the pump (9a) will pump water from the break tank into the
system. Once the required pressure has been reached, the pump will stop.
On twin pump models, a second pump (9b) is provided. The two pumps will run in a duty/standby configuration (i.e.
the active pump will alternate with each pump start).
The pump(s) are fitted with non-return valves (10a, 10b) to prevent backflow.
A drain valve (11) is provided for draining down the unit and for commissioning purposes.

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.

Electrical Power Supply
This equipment must be electrically isolated before removing the covers. Cables connected to the volt
free contacts may be supplied from another source and may remain live after the unit is isolated. These
must be isolated elsewhere.
All electrical connections must be carried out by a suitably qualified and competent person.
The mains power supply to the pressurisation unit must be connected into the fused terminal block as shown below:
On some larger models, the fused terminal block is replaced by a fused spur. If this is the case, the power supply
must be connected into the fused spur, as shown below:
It is recommended to supply power to the pressurisation unit via a lockable isolator. This should be
installed within 2 m of the equipment.
This equipment can be damaged by the high voltages produced by electrical installation testing
equipment. When performing electrical installation tests, the equipment must be isolated from the
supply.

If a drain valve is fitted to the break tank, ensure that it is closed. Then, turn on the mains water supply and
allow the break tank to fill.
When the float valve operates for the first time, it may not close immediately, causing the break
tank to overfill. Once the internals of the valve have been fully wetted this should not occur again.

This step is only necessary for Pro PDS units.
Make sure that the internal isolation valve within the pressurisation unit is closed. Failure to do
this may cause injury or damage to the equipment, system or property.
