Installation
Tightening Threaded Fasteners Before
First Use
After unpacking the pump, and before using it for the first
time, check and retorque all external fasteners. See the
Service
section for torque specifications. After the first day
of operation, retorque the fasteners again. Although pump
use varies, a general guideline is to retorque fasteners every
two months.
Use a compatible thread sealant on all male threads.
Tighten all connections firmly to avoid air or fluid leaks.
CAUTION
To avoid pump damage, do not overtighten the fittings
to the pump.
Grounding
WARNING
FIRE AND EXPLOSION HAZARD
This pump must be grounded when using
flammables. Before you operate the pump,
ground the system as explained below. Also
read the section
FIRE AND EXPLOSION
HAZARD
on page 2.
The polypropylene pumps
are
not
conductive. When
you pump conductive flammable fluids,
always
ground
the fluid system.
Never
use a polypropylene pump with
non-conductive flammable fluids as specified by your
local fire protection code. Consult your fluid supplier to
determine the conductivity or resistivity of your fluid.
To reduce the risk of static sparking, ground the pump and
all other equipment used or located in the pumping area.
Check your local electrical code for detailed grounding
instructions for your area and type of equipment.
Note:
This pump is shipped with an optional 90
_
mounting
bracket. In applications where priming is problematic use
this bracket to mount the pump horizontally to improve
performance.
Air Exhaust Ventilation
WARNING
TOXIC FLUID HAZARD
Read the
USING HAZARDOUS FLUIDS
and
FIRE AND EXPLOSION HAZARD
sections on page 2 before you operate this
pump with flammable liquids.
Be sure the system is properly ventilated for
your type of installation. You must vent the
exhaust to a safe place, away from people,
sources of ignition, animals or food
handling areas when pumping flammable
or hazardous fluids.
If the diaphragm ruptures, the fluid being pumped is
exhausted with the air. Place a container at the end of
the air exhaust line to catch fluid in case the diaphragm
ruptures, and disconnect the pump.
Mountings
CAUTION
The pump exhaust air may contain contaminants. If
needed, ventilate to a remote area to reduce possible
fluid contamination. See
Air Exhaust Ventilation
on
page2 and above.
D
Be sure the mounting can support the weight of the
pump, hoses, and accessories, as well as the stress
caused during operation.
D
For all mountings, be sure the pump is secured with
screws and nuts.
WARNING
To reduce the risk of serious injury, splashing in the
eyes or on the skin, and toxic fluid spills,
never
move or lift a pump under pressure. If dropped, the
fluid section may rupture. Always follow the
Pres-
sure Relief Procedure
on page 7 before you move
or lift the pump.
