• 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 leakage.
Assembling the Hose to the Valve
The end of the valve is specially tapered to
form a leak free seal when the hose is
properly installed.
Be sure to seat the hose completely so that
there is no gap. Push the hose until it covers
the end of the valve completely.
Suction and Discharge Valves
The suction and discharge valves located
on the pump head should not be inter-
changed 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.
