NAMEPLATE DATA

FIG 1 TYPICAL INSTALLATIONS

GENERAL PUMP INSTALLATION / SETUP (FIG 1)
City booster pump installation is shown per FIG 1. During pump use, ensure ball valves #1 and #2 are open, and ball valve #3 is closed.

#1 An Adjustable Pressure Regulator (APR#1) is required on the suction side of the pump (see fig 1) if the incoming water pressure can exceed the maximum input pressure.

#2 An Adjustable Pressure Regulator (APR#2) is required on the Discharge (see fig 1) to ensure maximum water pressure does not exceed local plumbing codes.
#3 A Pressure Relief Valve (PRV) connected to a drain is required (see fig

1. to safe guard plumbing from exceeding max pressures if the Pressure Regulators fail. Typically  the PRV would be set 5 psi higher than the APR#2.
   NOTE: Optional external water tank can be used to decrease the on/off cycle rate of the pump system, which can extend the life of the pump. (Typical tank 3 gallon draw down.) Set tank PSI equal to pump tank PSI.

The entire system must be air and water tight to maintain prime. Use thread tape on all connections to ensure no leaks. Hand tighten all threads and then add additional half turn with wrench.

FOR NEW PUMP INSTALLATION

1. The inlet and outlet flanges are tightened to the pump casing before shipment. For new pump installations, do not remove the flanges (FIG 2). Because of the use of  self-tapping screws, please use extra care when you have to remove the flanges for future maintenance.
2. Install unions on inlet and outlet piping prior to attaching them to the pump flanges. (FIG 3).
3. The pump foundation should be rigid enough to absorb any vibration from the motor, and the pump should be securely bolted to the foundation.
4. Please provide an adequate draining system to avoid damage in case of leakage, particularly when installed indoors. When the pump is installed outdoors, it should be  covered by a weather-proof, well ventilated housing.
5. The pump and all piping must be protected from freezing. When the pump will be exposed to temperatures less than 32°F (0°C), relocate it to a heated area.

FIG 2 DO NOT REMOVE FLANGES

FIG 3 INSTALL UNIONS

Indoor/outdoor area – ensure draining through 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, ensure 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. Ensure 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 (FIG4). 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 4 PRIMING ILLUSTRATION
a. Open ball valves #1 and #2, close 3.

b. Loosen the air relief plug.

c. Ensure water fills chamber from city water. Replace plug immediately to avoid excess moisture on pump.

d. Tighten the air relief plug.

If unit is shut down for an extended period of time or air enters into the system, it may be necessary to repeat the above priming instructions to ensure the internal pump  cavity is running with water to avoid dry running damage to the internal seals.

Checking and Setting Tank PSI
Pressure Tank Charge – Pressure tank air charge should be checked at regular intervals of every six months and after the pump has not been used for a prolonged period. To  check the tank pressure, turn off power, open the tap on discharge line to release pressure from the pump, unscrew the black plastic cover, and place a pressure gauge on it as shown (FIG 5).  Pressure should be adjusted to the original pre-charge as follows:
VP05 1/2 HP – 25 psi (1.8 Kg/cm2 )
VP10 1 HP – 35 psi (2.5 Kg/cm2 )
FIG 5 SET TANK PRESSURE

NOTE: If using optional water tank (FIG 1), set both tanks to the same pressure.

GENERAL OPERATION GUIDELINES

1. 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).
2. 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.
3. 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.
4. 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.
