Before connecting the unit to the primary circuit it is recommended to pressure test the system.

This can best be achieved by connecting mains pressure hose to the red ball valve and a hose or

bucket to the blue ball valve on the control unit. Open both valves fully & fill the system to purge

all traces of air from the system.

After all the air has been removed it is recommended to pressure

test the system with 6 bar pressure for 24 hours. We recommend maintaining

the system under pressure whilst screeding.

if there is a risk for the air temperature dropping below freezing, then you must protect the pipes

The Compact UFH System is designed for wall fixing and ideally should be

mounted in a horizontal position with the electrical connection box uppermost.

However, it can also be mounted vertical to pump up or down if desired.

Provision should be made to vent air to protect pump from cavitation.

The unit must not be floor mounted or in any position that inclines the pump shaft

vertical. Refer to the pump installation leaflet enclosed.

Choose the location for the unit ensuring adequate clearance and

accessibility

for pipework and any subsequent maintenance. This is particularly important

if

enclosed within a cupboard space for example.

Locate the unit on the wall and mark the hole fixing positions through the

bracket.

Take care to protect any electrical equipment and cables during handling.

When connecting the pipe to the manifold use the cutter supplied to cut the pipe square then

calibrate the cut end to round the pipe ready to accept the compression adaptor. As the adaptor has

integral ‘O’ rings it is not essential to use further sealant such as PTFE tape.
