❑ Per NFPA 1962 requirements, large diameter hose, marked “supply
Hose 3-1/2” to 5” (89 - 127 mm) diameter” shall not be used at operating
pressures exceeding 185 PSI (13 BAR). Large diameter hose, marked
“Supply Hose 6” to 5” (152 mm) diameter” shall not be used at operating
pressures exceeding 135 PSI (9 BAR).
❑ If leakage from the drain hole in the pump head is noticed or suspected,
the impeller must be removed and the mechanical seal must be
inspected and/or replaced.
❑ If a pump is operated without water for extended periods, or without dis-
charging water, it could overheat. This can damage the mechanical seal,
impeller or the drive mechanism.
❑ DO NOT attempt to pump until all the GREEN pump indicators in the cab
and panel are ON. Also see Section 3 “Basic Operation” on page 27 for
additional information.
❑ DO NOT advance the throttle unless the OK TO PUMP indicator is illumi-
nated. Also see Section 3 “Basic Operation” on page 27 for additional
information.
❑ DO NOT leave the cab, after selecting the PUMP mode, until all the
GREEN pump indicators in the cab and panel are illuminated. Also see
Section 3 “Basic Operation” on page 27 for additional information.
❑ DO NOT attempt emergency manual shift procedures while the engine is
running. Also see Section 3 “Basic Operation” on page 27 for additional
information.
❑ Never attempt to shift the pump (PUMP-to-ROAD, vise versa) while the
truck transmission is in gear. Always shift the truck transmission to NEU-
TRAL (N) and verify the speedometer is ZERO (0) before shifting the
pump. Also see Section 3 “Basic Operation” on page 27 for additional
information.
❑ DO NOT reduce the pressure on the INTAKE gauge below zero (0).
Serious damage to the water main could result.
❑ Some vehicles maintain air on the shift cylinder continuously regardless
of transmission setting, and some only have air applied when the vehicle
transmission is in NEUTRAL.
Use caution when servicing.
❑ Use only PAC-EASE Rubber Lubricant Emulsion (or equal) on the rubber
mechanical seal parts to ease installation. DO NOT use other lubricant
types as damage to the mechanical seal and seat could occur.
❑ Before connecting any cord sets or wiring harnesses, inspect the seal
washer in the connector.
If the seal washer is missing or damaged, water can enter the connector
causing corrosion. This could resulting in possible system failure.
