Cp2 Circulator Pump Body Adapter - Kamco CF40 Operating And Servicing Manual

CP2 CIRCULATOR PUMP BODY ADAPTER

The CP2 adapter has been developed for use with heating
system power flushing pumps, to enable them to be
connected directly onto the body of standard heating
system circulator pumps, after removal of the motor
head.
The compact dimensions of the CP2 allow for easy
connection of a power flushing pump even in boilers
which contain the circulator pump within the casing, such
as combination and system boilers, where access is often
difficult, or which have non-standard connections.
When using the CP2, there is no need to physically
disconnect the circulator pump 1.1/2" unions, which are
often seized and difficult to remove.
During power flushing, the circulator pump body (volute),
which may often contain considerable corrosion debris, is
included in the cleaning process.
All radiators may be power flushed, as there is no need to
remove one to connect the power flushing pump onto
the radiator tails.
The central heating (primary) water side of the secondary
heat exchanger of combination boilers can be efficiently
flushed with the heat exchanger in place in the boiler
casing, giving useful time savings.

Instructions for use
Before you start:
Switch off or electrically isolate the existing circulation
pump and make safe the cable and connectors. Protect
the area around the pump from water leakage.
Close the circulator pump isolation valves (where fitted),
remembering that it is common for valves not to seal
completely even though they are apparently fully closed.
Procedure:
1. Remove the four hexagon head screws and then
carefully remove the circulator pump head and motor
assembly, leaving the circulator pump body installed as
normal.
2. As you withdraw the pump head, a small volume of
water (the capacity of the pump itself and a short length
of pipe work) should be collected in a drip tray, and
disposed of safely.
3. Clean the loose rust off the inside of the pump body
with a cloth and make sure that there is a clean surface
area for both of the supplied O rings to seat on. Use a flat
bladed screwdriver if necessary.
4. A small quantity of silicon
grease can be used to hold the
central 'O' ring in place on the
brass centre boss whilst securing
the CP2.
5. Offer up the adapter and attach
with the hexagon socket cap screws provided. Using a
hexagon key tighten the bolts evenly, using strong finger
pressure but no extra mechanical leverage.
6. Using the supplied large
hexagonal centre boss key, gently
tighten the brass centre boss until
you feel it seal on the inner 'O'
ring. Only medium finger pressure
is necessary.
NOTE: Do not overtighten, as this may damage the large
'O' ring, or the main body of the CP2 adapter.
7. Connect the hoses to the adapter and to the supply
and return hoses of your power flushing pump.
8. Open the isolation valves on the Clearflow power
flushing pump
9. Slowly open the circulator pump isolation valves, and
check the CP2 adapter and all hoses for leaks.
