Prior to inserting the pipe, mark the insertion depth with a soft pencil at a
distance of 31 mm from the end to be inserted (see Fig 8).
7.
Check in the mouth of the fitting that the 'O'-ring, nylon washer and collet are
in position as shown (see Fig. 8).
8.
Push the pipe firmly into the fitting, until the pencil mark is level with the top
of the collet. At the same time the pipe should hit the internal stop inside the
fitting.
9.
To release the joint, push pipe firmly into the fitting, hold the collet down and
gently remove the pipe. If the system has been filled with water, care should
be taken to isolate the pump and towels used to absorb any spilled water.
10.
Make sure that any pipework that could become frozen is properly insulated.
Fitting the Hose to Pump
The pump inlet and outlet ports have factory assembled fittings which are specifically
designed for connection to the G ¾ female captive nut on the flexible hoses.
The hose end is fitted with a rubber sealing washer which is held captive within the
nut assembly.
11.
Locate the hose into position and screw the nut fully onto the pump fitting by
hand. Use a spanner or appropriate grip tool to make a water tight seal.
Do not overtighten!
