TYPICAL INSTALLATION
(Cold Water, Negative Duty Single Pump System)
STEP 1: PRE-INSTALLATION ASSEMBLY
Pressure Check and Assembly of Pressure Vessel
a)
Your pump is supplied in two parts, the main pump and pressure vessel. The
pressure vessel is pre-charged with air at the factory (see table below). This
pressure should be checked at the schrader valve using a tyre pressure gauge and
adjusted if necessary using a car or bicycle pump prior to installation.
b)
To assemble, remove protective plastic cap from pressure vessel thread. Ensure that
the fibre washer is present at the bottom of the fitting point. Screw the pressure
vessel clockwise until hand tight to achieve a water tight connection.
