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.

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.
