- Unpumped units use the same pipework to the pressure vessel for both filling and
emptying the vessel. This should be connected to the mains as shown in Figures 1 & 3.
- Pumped units have a seperate inlet and outlet. Arrows on the brass end of the pump
clearly show the inlet and outlet, refer to Figure 6. The included anti vibration hoses should
be used to make the connections between the pipework and AccuBoost unit. The supplied
flat washers should be used when attaching the hoses. The hoses should be finger tight
plus one quarter turn. Do not twist or bend the hoses so that they kink as this will restrict
the flow and also invalidate the warranty.
