GENERAL SAFETY INFORMATION

Protect yourself and others by observing all safety
information. Shut off power and drain pressure from
system prior to service.

DESCRIPTION

The FLOJET 2840 series Booster Pump Systems are
designed to provide a constant water pressure of 25 to
45 psi (1.7 - 3.1 bar) and maximum flow of 3.5 or 4.5
GPM at 10 psi (0. 7 bar). The pump is fully automatic
with a built-in switch and check valve to maintain
system pressure and will supply smooth water flow from
a trickle to full flow Typical uses are; Commercial Ice
Machines, Pure Water Dispensing, Water Purifiers,
Small Domestic and Commercial Appliances where the
water supply pressure is very low or fluctuates widely.

OPERATION

IMPORTANT - For correct operation, the tank must be
properly pressurized on the air side before the pump is
started. Follow instructions on the tank label and check
air pressure after filling and before starting the pump.
The air valve is a standard tire valve. Compressed air
hose or hand pump may be used to pressurize.
Pressure can be reduced by pressing the center pin in
the valve.

Make sure pump inlet connection is securely connected
to the water supply and no inlet valves are open. Open
all valves or taps on outlet side to purge air from the
system. Turn power on to the pump, pump will start up.
Allow system to pump for a minute or until all the air has
been purged from the system. Close all valves in the
system, the pump will pressurize the tank, shut off and
operate automatically to maintain pressure In the system.

To completely fill the pressure tank for maximum
volume, shut off power to pump and open faucet (or valve)
closest to tank. Trapped air will be expelled. Turn on
power to pump. and close faucet when water is free of air.

WINTERIZING TIP

When units are exposed to freezing conditions.

1. Open discharge valve (Faucet nearest to the
Booster System).

2. Open inlet side to pump (Remove inlet hose to the
Booster System).

3. Run Pump for approximately 2 minutes, (Dry) or
until system is out of fluid.

4. Leave discharge. value open and inlet hose
removed until next usage.

DO NOT USE PUMP IN A FLAMMABLE

ENVIRONMENT. DO NOT USE TO PUMP

FLAMMABLE OR EXPLOSIVE FLUIDS

SUCH AS GASOLINE, FUEL OIL,

KEROSENE, ETC.

MOUNTING

The FLOJET 2840 Series Water Pressure System should
be mounted in a dry and adequately ventilated area.

Select a location where the plumbing is as direct as
possible and the inlet strainer is visible and accessible
for cleaning.

The unit can be floor or wall mounted. If wall mounted,
the Pump head should be down or lower than the motor.

Fasten base securely with the four rubber mounting feet
assembled to base as shown below.

PLUMBING

Fasten strainer in a visible and accessible location for
future cleaning. Use 3/4” ID hose between pump inlet &
strainer. Connect strainer inlet to water supply line and
clamp all hose connections securely to avoid air leaks.
IMPORTANT - if water supply line has pressure
fluctuations that may exceed 30 psi (2.1 bar) - use a
pressure regulator to limit inlet pressure to 30 psi (2.1
bar) maximum.

Regulator may be installed at any convenient location
between water supply and inlet strainer.

ELECTRICAL

RISK OF AN ELECTRICAL SHOCK!

When wiring an electrically driven pump, follow all
electrical and safety codes, as well as the most recent
National Electrical Code (NEC) and the Occupational
Safety and Health Act (OSHA).

RISK OF PRODUCT DAMAGE!

Make certain the power source conforms to the pump
voltage. Be sure all power is disconnected before
installation or removal.

Use the maximum recommended fuse for pump
protection. Recommended fuse amp rating is located
on pump label. Failure to provide correct overload
device may result in motor failure.

For 115V AC plug AC cord into a conventional 115V AC outlet.
