To reduce the risk of serious bodily injury including
fluid injection and splashing in the eyes or on the
skin, which may be caused if a component ruptures,
all accessories added to the reciprocator power
supply side must have at least a 1500 psi (105 bar)
maximum working pressure and those to the pump
fluid outlet side must have at least a 375 psi (26 bar)
maximum working pressure.

Low–level Cutoff Valve To install, screw the low–level
cutoff valve into the bottom of the pump intake tube or the
suction tube. This valve closes the pump intake when the
fluid level is low, causing the pump to stall to avoid run-
ning dry.
WARNING
Pump Outlet Drain Valve
A pump outlet drain valve (D) is required in your sys-
tem. This valve helps relieve pressure in the dis-
placement pump and hose when shutting down the
system and in case of a clogged outlet hose. Install
the valve close to the pump outlet.
Pump Outlet Drain V alve Install a drain valve (D) close
to the pump fluid outlet to assist in relieving fluid pressure
in the pump when the pump is shut off.
Ground Wire A ground wire is required. See Acesso-
ries, page 22.
