NEMA 4X Constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental
contact with enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, snow,
windblown dust, splashing water, and hose-directed water; and that will be undamaged by external formation
of ice on enclosure.
IP66 No ingress of dust; complete protection against contact. Water projected in powerful jets against enclosure
from any direction shall have no harmful effects.

5.1 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 maintenance.
NOTE: It is recommended to have a pressure relief valve at the discharge side of the of pump to prevent
premature wear and damage to the pump, in the event that the discharge line becomes blocked.
NOTE: The does not require back pressure. Back-pressure valve may be desired to maintain consistent pump
flow into inconsistent system pressure.
5.0 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.
!
CAUTION
!
CAUTION
Check system pressure and piping pressure limits before installation.
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).
