Checking and Setting Tank PSI – Factory tank

PSI settings are 26 PSI (1/2 hp) and 36 PSI (1 hp).

If the inlet PSI is HIGHER than the factory settings,

increase the tank PSI to be approximately 5 PSI

higher than incoming pressure. To check the tank air

pressure, turn off power, open a tap on the discharge

line to release pressure from the pump, unscrew

the black plastic cover and apply a pressure gauge

to the valve as shown in FIG 3. Add tank pressure

as required, due to the tanks small volume, minimal

air volume is needed to increase tank pressure.

Reinstall black plastic cover.

FIG 3 SET TANK PRESSURE

IL1307

NOTE: If using optional water tank (FIG. 1), set both

tanks to the same pressures.

GENERAL OPERATION GUIDELINES
• What Causes The Unit To Start? – The pump

will turn ON when the flow rate is greater

than 0.7 GPM or when the pressure output is

less than the pump pressure activation point

(approximately 25 psi - 1/2hp, 35 psi - 1hp).

• Dry Run Protection - After the unit recognizes

a continual low flow of water, the unit will

shut down to protect itself from running dry.

Hourly, it will turn on to sample the water flow

requirements, and return to shut down if running

dry. The home owner can fix the run dry issue

and return the pump to normal operation by

unplugging the pump for 5 seconds.

• Dead Head Protection - If there is no water

demand (discharge is shut off), the unit will shut

down to protect the pump from damage. Once

water flow is restarted, the pump will re-start the

power automatically.

• Rapid Cycle Protection – If the unit cycles

repeatedly on/off, the unit will shut down to

protect the pump life. The optional water tank

not maintaining pressure could be a potential

cause. Hourly, it will turn on to sample the water

flow requirements, and return to shut down if the

problem persists. The home owner can fix the

concern and return the pump to normal operation

by unplugging the pump for 5 seconds.

LOCATION

Indoor/outdoor area – insure draining thru pressure

relief valve is available in order to avoid damage in

case of leakage.
Outdoor area – unit should be covered by a weather

proof housing, insure adequate ventilation.
FREEZING (OR REMOvING PUMP FOR

MAINTENANCE)

The pump and all piping must

be protected from freezing. If freezing weather

is forecast, and the unit will be exposed to

temperatures less than 32ºF (0ºC), remove the pump

by closing off ball valves #1 and #2, (see FIG. 1) and

removing the pump, using the union connections.

Store pump in a heated area. Open ball valve #3 to

allow city water to pass forward if desired. Insure

the piping is adequately protected from the cold

environment.
OPERATING CONDITIONS
Ambient temperature range 32ºF (0ºC) to 104ºF

(40ºC).

PRIMING
After installation (with the pump OFF), open ball

valves #1 and #2, and slowly unthread the air relief

plug (FIG 2). Allow inlet water pressure to fill the

pump cavity and remove in-line air pockets. After

the pump cavity fills with water, retighten the air relief

plug.

FIG 2 PRIMING ILLUSTRATION

a. Open ball valves #1 and #2, close 3.

d. Tighten the air

relief plug.

c. Ensure water fills

chamber from city water.

Replace plug immediately

to avoid excess moisture

on pump.

IL1207

b. Loosen the air relief plug.

If unit is shut down for extended

period of time or air enters into the system, it may be

necessary to repeat the above priming instructions to

insure the internal pump cavity is running with water

to avoid dry running damage to the internal seals.
