Release system pressure then drain the pipe run where the device is to be
located (it may be necessary to drain the whole system). When installing
below a boiler or other object, allow 250mm clearance from the top of the
canister to beneath the object, to enable the lid assembly to be removed
when servicing.
The device has been designed to facilitate various inlet and outlet
configurations. Most configurations will require Elbows. For soldering we
recommend 28x Yorkshire Solder Ring Elbow YP1222mm (code08290), or
for compression we recommend 2 Yorkshire copper KS61522mm (code
61124K) and the fitting instructions (which follow) are based around
dimensions of these elbows. For clarity the recommended solder and
compression fittings require the same dimension of cutout.
Vertical pipe run: Measure and mark a 110mm section for a 22mm unit,
as shown below. Remove this marked section using a pipe cutter as
shown. Now create 64mm and 106mm of 22mm copper pipe to attach
between the respective elbow and compression fitting on the inlet/
outlet. Tip: Reuse the cut out section.
Horizontal pipe runs: Measure and mark 73mm section and remove
the marked section with a rotary tube cutter. Create 64mm and 134mm
lengths of 22mm copper pip to attach between the respective elbow and
compression fitting on the inlet/outlet. Tip: Reuse the cut out section.
Prepare the pipe and fittings, lubricate the olives and connect the
valves on the pipe work, only hand tighten the connections at first.
