STANDARD MODEL NUMBERING SYSTEM
The standard model numbering system is used for models up
to -500. Numbers -500 and over are used for variations from
standard assemblies such as special pump or tank
specifications. Consult the factory for special models to meet

DESCRIPTION
The FLOJET 2820 series Booster Pump Systems are
designed to provide a constant water pressure of 45 to
70 psi (3.1 - 4.8 bar) and maximum flow of 1.5 GPM at
10 psi (0. 7 bar). The pump is fully automatic with a builtin 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
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.
before the pump is
MOUNTING
The FLOJET 2820 Series Water Pressure System should
be mounted in a dry and adequately ventilated ar
ea.
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.
Vertical Horizontal
PLUMBING
Fasten strainer in a visible and accessible location for
future cleaning. Use 1/2” ID hose between pump inlet &
strainer. Connect strainer inlet (1/2” hose) 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, such as Flojet 1750 series.
Regulator may be installed at any convenient location
between water supply and inlet strainer.
.
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).
Open inlet side to pump (Remove inlet hose to the
2.
Booster System).
3. Run Pump for approximately 2 minutes, (Dry) or
until system is out of fluid.
Leave discharge. value open and inlet hose
4.
removed until next usage.
