1. Hose connections to the Quantum
1a. Ensure that both valves are in the closed position
(horizontal).
1b. The Quantum has two 5 metre flow and return
hoses, fitted with ¾” female brass hose
connectors on either end of each hose.
One end of both flow and return hoses should be
screwed onto the corresponding ¾” brass nipples
on either side of the Quantum pump. The other
ends of these hoses will be connected into the
heating system.
1c. Connect the brass overflow hose connector to
the 3/4" BSP male overflow fitting on the rear of
the pump tank, and lead to a suitable drain point.
1d. Connect the 8mtr dump hose to the brass nipple
on the reverse of the valve plate, and lead the
hose to a toilet pan or drain pipe gully leading to a
foul sewer.
1e. Connect mains water supply hose 3/4" BSP
female hose connector securely to the 3/4" BSP
male fitting attached to the rear of the orange
water inlet valve. Fill the Quantum tank with water
to 15cm above the minimum liquid level, and then
close the water inlet valve.
1f. Plug in the Quantum to a suitable 13 amp supply
fitted with an RCD adapter.
2. Hose connection to the system
Connect the flow and return hoses of the
Quantum pump to the system at the selected
point. This may be either:
2a. Across the 1.1/2" BSP unions left once the
circulating pump has been removed. The
circulating pump isolating valves should be closed
to isolate the flushing pump from the system until
power flushing is commenced.
A pair of 0. 5 metre long
adapter hoses, enabling
the Quantum to be
connected across the
1.1/2" unions, are
supplied as standard.
When used, these are
screwed directly onto
the ¾” female brass
hose adaptors of the
flow and return hoses,
giving a total hose
length of 5.5 metres.
2b. Connection via the
optional CP2 pump
head adaptor (see page
G.2). Remove the allen
bolts that attach the
circulation pump head
to the pump body.
Attach the adaptor to
the pump body and the
flow and return hoses to
the short lead hoses.
2c. Across the "tails" of a
radiator (having drained
and disconnected the
radiator) using
appropriate 1/2" or 3/4"
BSP adaptors
to
connect to the valves.
The radiator valves
should be closed to
isolate the flushing
pump from the system
until power flushing is
commenced.
This is likely to be the
least effective method
due to the restrictive effect that valves
(particularly thermostatic) may have on the flow
rate.
The above method is generally used on a
combination boiler system when a CP2 adaptor is
not available.
2d. Across the flow and return connections at the
boiler, isolating the boiler itself. This is the
preferred method when flushing a heating system
prior to installing a new boiler, as corrosion debris
may be purged from the heating system before
the new boiler is attached. This is important with
all modern boilers, particularly so if the new boiler
incorporates a plate type heat exchanger with
complex and narrow water passages.
