3. Monitor the intake and discharge master gauges. When the pump is
primed, the intake reading falls below zero (0), and the discharge pressure
starts to increase. You may also hear or see water discharging from the
primer, indicating the pump is primed.
4. Gradually open the discharge valve until water emerges in a steady stream.
Then open the other discharge valves to the desired setting.
5. Gradually open the engine throttle until the desired pressure or flow is
achieved.
CAUTION !
DO NOT CAUSE A WHIRLPOOL AT THE STRAINER. THIS ALLOWS AIR INTO THE
PUMP CAUSING ROUGH OPERATION AND PULSATION. REPOSITION THE
STRAINER OR REDUCE FLOW.
DO NOT USE THE PRIMER TO EVACUATE AIR FROM LDH SUPPLY HOSES.
NFPA SPECIFIES AIR BLEEDS FOR THIS PURPOSE. HIGH PRESSURES CAN
DAMAGE THE PRIMER.
Note: Holding the primer ON for about one (1) or two (2) seconds while discharging
water after prime helps keep the primer clean of debris and promotes longer primer
life.
