Filling & Venting
Follow the steps below to
Fill and Vent
the
system in the correct order:
1. Ensure all system valves are open fully.
2. Fill the system using the incorporated
filling loop to the recommended pressure
(min 1.0 bar – max 1.5 bar).
While filling the system, air should be released
via the manual or automatic air vents within the
system.
During the filling process it is important to
release air from the heat pump. There is a
manual air vent on the top of the unit.
3. Ensure the system is watertight.
Follow the steps below to
Flush
the system in
the correct order:
1. Connect the fill & flush pump to the fill &
flush valve (as shown).
It is important to connect the feed hose from
the fill & flush pump to
Valve A
and the drain
hose to
Valve B
. This ensures the water flows
through the Heat Pump first and then out to the
open circuit. It also ensures that any trapped
air in the Heat Pump and/or the open circuit is
pushed back to the fill & flush pump’s reservoir
and expelled from the system.
2.
Valve C
is turned to the closed position
(90° to the pipe direction). Open valves A
and B and switch on the fill & flush pump.
3. Water is circulated through the system for
