Warnings
Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When
these symbols appear in the body of this manual or o n warning labels, refer back to these Warnings. Product-specific
hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.
FIRE AND EXPLOSION HAZARD
When flammable fluids are present in the work area be aware that flammable fumes can ignite or
explode. To help prevent fire and explosion:
• Use equipment only in well ventilated area.
• Eliminate all ignition sources, such as cigarettes and portable electric lamps.
• Ground all equipment in the work area.
• Keep work area free of debris, including rags and spilled or open containers of solvent.
• Do not plug or unplug power cords or turn lights on or off when flammable fumes are present.
• Use only grounded hoses.
• Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment until
you identify and correct the problem.
• Keep a working fire extinguisher in the work ar ea .
ELECTRIC SHOCK HAZARD
This equipment must be grounded. Improper grounding, setup, or usage of the system can cause electric shock.
• Turn off and disconnect power cord before servicing equipment.
• Connect to grounded outlet protected by Class A GFCI.
• Use only 3-wire extension cords.
• Ensure ground prongs are intact on power and extension cords.
PRESSURIZED EQUIPMENT HAZARD
Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause
serious injury.
• Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning,
checking, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or
swallowed.
• Read Safety Data Sheet (SDS) to know the specific hazards of the fluids you are using.
• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

Warnings
PERSONAL PROTECTIVE EQUIPMENT
Wear appropriate protective equipment when in the work area to help prevent serious injury, including
eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not
limited to:
• Protective eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
• Do not operate the unit when fatigued or under the influence of drugs or alcohol.
• Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all
equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information
about your material, request Safety Data Sheet (SDS) from distributor or retailer.
• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.
• Check equipment regularly. Repair or replace wo rn or damaged parts immediately with genuine man ufacturer’s replacement parts only.
• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create
safety hazards.
• Make sure all equipment is rated and approved for the environment in which you are using it.
• Use equipment only for its intended purpose. Call your distributor for information.
• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.
• Do not kink or over bend hoses or use hoses to pull equipment.
• Keep children and animals away from work area.
• Comply with all applicable safety regulation s.

Installation
NOTICE
It is recommended that adequate surge protection be used
in order to protect products from voltage changes in your
application.
Grounding
The equipment must be grounded to reduce the risk
of static sparking and electric shock. Electric or static
sparking can cause fumes to ignite or explode.
Improper grounding can cause electric shock.
Grounding provides an escape wire for the electric
current.
• Never remove ground wire from plug. Connect to
grounded outlet protected by Class A GFCI.
Pump: grounded through electrical cord.
Fluid lines: use only electrically conductive lines.
Fluid supply container: follow local code.
NOTICE
In order to prevent over pumping at low back pressure (less
than 50 PSI) install an inline check valve on the outlet line.
Flush Before Using Equipment
The equipment was tested with water. To avoid contaminating your fluid with water, flush the equipm en t with a
compatible solvent before using the equipm en t. See
Flush the Equipment, page 9.
Location Requirements
Select a mounting location convenient to both the chemical supply and a source of power for the pump.
NOTICE
Do not install the pump in a location where the ambient
temperature exceeds 120
will affect the output as well as the useful life of the pump.

Plumbing Requirements for Stainless Steel / Plastic Fluid Sections
The Mongoose pump uses carefully matched components to achieve a predictable metering output. This
predictability can only be maintained if all fitting sizes
remain unaltered.
All connections should be double checked to insure
against leakage. If hazardous chemicals are being
pumped, use shielding around outlet fluid lines. NOTES:
• There is an approximate 2.5 psi capability lost for
every 1 foot of vertical rise of the outlet fluid line to
the injection point.
• Do not attempt to reduce tubing size; this may
reduce performance of unit.
Stainless Steel Fluid Section Models
Inlet and outlet valves are both 1/4 in. NPT fittings.
NOTE: Apply PTFE tape to threads on NPT fittings.
Plastic Fluid Section Models
Inlet and outlet valves use 3/8 in. or 1/4 in. tubing connectors, and 3/8 in. or 1/4 in. tubing. See F
IG. 1.
NOTE: The prime/bleed valve on the plastic fluid section
includes a 1/16 in. clear poly tubing. This tubing is to be
used only with the prime/bleed valve and is not intended
for pressurized use. Do not use with the inlet and outlet
valves.
Tighten connectors no more than a 1/4 turn after the
connection feels snug. Hand tighten only. Do not overtighten.
NOTE: Do not apply PTFE tape to threads.

Mounting and Chemical Supply
Connection
Failure of the diaphragm or a rupture in the fluid lines
may cause exposure to toxic fumes or a loss of solution in the tank. Install a fluid line shutoff valve as
close to the chemical tank as possible to minimize the
loss of, and exposure to, potentially toxic chemicals.
Flooded Suction Mounting
The fluid end (9) of the pump, shown in FIG. 2, is set up
to accommodate mounting of the pump next to the
chemical supply container (G), shown in F
NOTE: The inlet valve (2 or 102) must be kept in a vertical position for proper operation. The fluid end (9 or 109)
can be removed and rotated 90° if needed.

Injection Check Valve Connection (Plastic
Fluid Section only)
The injection check valve is designed to prevent a back
flow and to inject chemical into a piping system. This
valve must be mounted within 45° of vertical (see F
3).
1. Install the 1/2 in. NPT end into the piping system.
Apply PTFE tape to this end only.
2. Connect the outlet fluid line (E) from the Mongoose
pump to the to the other end of the injection check
valve.

The pump is mounted on top of a chemical supply container, shown in F
pump to the bottom of the container does not exceed
5 ft.
A weight is provided to hold the inlet fluid line (D) and
foot valve (H) in a vertical position at the bottom of the
container. Keep the inlet fluid line (D) relatively short,
and avoid high spots or bends.
NOTE: Do no allow the foot valve (H) to lie horizon ta lly
in the tank. This defeats the action of the valve and
causes the pump to lose prime.

Three-Function Valve Injection Assembly
(Plastic Fluid Section only; Optional)
The optional three-function valve injection assembly
provides three functions in one injection valve asse mbly.
• Anti-siphon - which allows metering of liquids into
the inlet side of a circulating pump. It provides protection against an accidental application of suction
pressure at the fluid injection point. A PTFE coated
diaphragm provides a positive anti-siphon action.
• Back pressure - which permits metering into atmospheric discharge (such as an open container) without overpumping.
• Line check - which permits removal of outlet tubing
without release of system fluid.
