PRE-INSTALLATION ASSEMBLY
Pressure Check and Assembly of Pressure Vessel
a) Certain models are supplied in two parts, the main pump and the 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 (Fig. 5) using a tyre pressure
gauge and adjusted if necessary using a car or bicycle pump prior to installation.
b) To assemble the vessel (when applicable), remove protective plastic cap from fitting
point. Ensure that the ‘O’-ring is present and correctly fitted in the location groove at
the bottom of the fitting point. Screw the pressure vessel clockwise into the fitting
point until hand tight to achieve a water tight connection.
NOTE: Do not over tighten pressure vessel.
