1.
Unlock the front access panel
Unlock and lower the front access panel using the
keys supplied.
2.
Fix unit to wall
Fix the unit to the wall via suitable fixings.
3.
Connect the pipes
Connect the heating system flow and return pipes
to the heater pipe work. Pipe entry/exit can be
made through either the back of the unit or by
using the pipe knockouts on the bottom of the
unit. Do not use soldered fittings to the heater
pipe work as the heat generated may cause
damage to internal wiring and components.
Compression fittings should be used.
Installation
Note: We recommend the use of full-flow service
valves. The valves should be accessible after
completion of the installation. We also advise the
fitting of an air vent at the highest point on either
the flow or return pipe to remove any air trapped
within the system.
4.
Open the service valves
Open the full flow service valves and check for
water leaks. Remove any trapped air from the
unit via the built in bleed screws as shown in the
diagram below. Note: Ensure the motorised valve
is set to the auto position.
5.
