The pump may be used either
horizontally or vertically with the hose
end downwards. The pump is
equipped with a pressure relief valve
factory set at the maximum operating
pressure. Before use unscrew transit

volume available.

automatically switch from low pressure
(high flow) operation to high pressure
(low flow) as the pressure increases.
