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.
