Assembling the Hose to the Valve
The end of the valve is specially tapered to
form a leak free seal when the hose is prop-
erly installed.
Be sure to seat the hose completely so that
there is no gap. Push the hose until it cov-
ers the end of the valve completely.
Suction and Discharge Valves
The suction and discharge valves located
on the pumphead should not be interchanged
as they are different internally. The discharge
valve is fitted with a valve guide and will not
function properly if used on the suction side.
• Repeat the same installation procedure for
the hose connections on the discharge end
with the injection assembly (HI721004).
• Secure the hose so that its movement is
minimized when the pump is operating.
Excessive hose movement could cause
the connectors to loosen and result in leak-
age.
