Mounting Location
1. Choose an area located near the chemical supply tank, chemical injection point, and electrical supply. Also,
choose an area where the pump can be easily serviced.
2. Finding a secure surface and using the provided mounting hardware, mount the pump close to the injection
point. Keep the inlet (suction) and outlet (discharge) tubing as short as possible. Longer discharge tubing
increases back pressure at pump head.
NOTE
: Mounting the pump lower than the chemical container will gravity-feed chemical into it. This “flooded
suction” installation will reduce output error due to increased suction lift. A shut-off valve, pinch-clamp, or
other means to halt gravity-feed to the pump must be installed during servicing.
NOTE
: Install a back flow prevention check valve at the discharge side of the pump to prevent the system fluid
from flowing back through pump during pump maintenance.
NOTE
: It is recommended to have a pressure relief valve at the discharge side of the of pump.

INSTALLATION
All diagrams are strictly for guideline purposes only. Always consult an expert before installing
metering pump on specialized systems. Metering pump should be serviced by qualified persons
only.
Always wear protective clothing, face shield, safety glasses and gloves when working on or near
your metering pump. Additional precautions should be taken depending on solution being
pumped. Refer to MSDS precautions from your solution supplier.
Risk of chemical overdose. Be certain pump does not overdose chemical during backwash and
periods of no flow in circulation system.
Be sure that installation does not constitute a cross connection with drinking water supply.
Check your local plumbing codes.
The pump should be serviced by qualified persons only. If equipment is used in a manner not
specified in this manual, the protection provided by the equipment may be impaired.
The pump should be supplied by an isolating transformer or RCD (operating current less or
equal 30 mA).
