Figure 17-1. Pressure Relief Valve Layout

The Pressure Relief Valve will be fitted between the pump in the pressure hose and the Fast Valve.

The Pressure Hose is a 1 ¼" hose; it will need to be cut to add the Pressure Relief Hose.

A Skin Fitting (supplied) must be fitted to the tank, for the relief chemical. Fit the Skin Fitting approximately 20 centimetres above the base of the tank, so that "frothing" does not occur and agitation is not enhanced.

The dealer/end users will have to supply an appropriate 1 ¼" chemi- cal resistant hose, to connect the Pressure Relief Outlet and the Skin Fitting. An appropriate hose clamp will also have to be supplied.

Once the pressure relief valve is fitted to the pump. Pressure Outlet Hose and then connected to the tank skin fitting, wind the Pressure Regulating Adjuster fully out, this will result in all fluids being "dumped".
