- DO NOT run pumps continuously for longer then 30 minutes under a no flow (dead headed) situation.
- DO NOT over tighten plastic threaded connections. Breakage can occur, resulting in fluid exposure.
- If valve on end of hose is equipped with an internal check valve that does not allow air removal the pump
may need to be primed first in order to build up enough pressure to expel air in the system. The length of
hose, fluid level of tank and additional accessories will affect pump priming. It may be necessary to first fill
pump with water or chemical before connection of the hose.
- Teflon Tape is the recommended thread sealant on all pipe connections.
- Replace cartridge O-ring and Bottom Gasket if Pump Cartridge is removed or replaced.
- Flush pump assembly with water prior to any maintenance or new installation, as exposure to chemicals
can cause bodily harm. Gloves and proper eye protection should be worn.
