PRE-INSTALLATION

APPLICATION
This unit is a single stage jet pump designed for shallow water well applications, where the water level is less than 25 ft. deep. If the water level to the pump is deeper than 25 ft., a convertible jet pump or a deep well submersible pump should be used. A pressure switch pre-set at 30 psi “on”, 50 psi “off” has been installed on the pump. The pressure switch will automatically turn the pump on and off based on the system pressure. Do not use for sewage pumps, if do this, will void the warranty.
TOOLS REQUIRED SPECIFICATIONS

DETERMINE THE DEPTH OF YOUR WELL
Tie a small but heavy weight to the end of a piece of string. Lower the weight into the well until it reaches the bottom. Make a mark on the string at ground level. Pull the weight out of the well and measure from the bottom of the weight to the ground level mark. This is the depth of your well. Subtract 5 ft. from the depth of your well. This number should not exceed the maximum rated depth for your pump. If it does, it will greatly hinder or prevent the proper operation of the pump.
LOCATION OF THE PUMP
Decide on the area for the pump installation. Select a pump location with adequate space for future pump maintenance. It can be located in the basement or utility room of the house, at the well, or between the house and the well. If installed outside of the house, it should be protected by a pump house with auxiliary heat to prevent possible  freezing. Protect the pump against flooding and excess moisture. The well also should be protected for sanitary reasons. Mount the pump as close to the well as possible.
TANKS – PRE-CHARGED STORAGE
For best performance of the pump, it is recommended that you use a diaphragm pressure tank (sold separately). It is best to have this in place before installing the pump. A pre-charged storage tank has a flexible bladder or diaphragm that acts as a barrier between the compressed air and water. This barrier prevents the air from being absorbed  into the water and allows the water to be acted on by compressed air at initially higher than atmospheric pressures (pre-charged). More usable water is provided than with a conventional type tank. Air pressure in the tank must be 2 psi lower than the “cut-in” of the pressure switch.
CAUTION: In order for the pump and tank to operate properly, the pressure tank needs to be drained of all water BEFORE INSTALLING THE NEW PUMP. After draining, if you are using the supplied 30/50 psi pressure switch at the pre- set settings, add or adjust the air pressure in the tank to 28 psi of pressure BEFORE start up.
PREPARATION
Parts you may need for assembly not include（Fig.1）

Optional Parts For Assembly not included (Fig.2)

SHALLOW WELL APPLICATION

Shallow well systems are identified by one pipe going to the well, lake or river.

1. CASED WELL APPLICATION, 4” OR LARGER CASING (Fig.1)
   A hole bored into the earth with machinery. Depths range from a few feet to 25 feet. Common well diameters are 4″, 5″, 6″ and 8″ for domestic water wells.

2. WELL POINT (DRIVEN POINT) APPLICATION (Fig.2)
   Pipe with a pointed screen is driven into the ground below the water table. The depth is usually less than 25 feet. Available diameters are 1″ through 2.

3. APPLICATION FOR SURFACE WATER (Fig.3)
   One pipe goes into lake, river, cistern or ponds，suction lift is less than 25′. Install a screen around the inlet pipe to prevent the entrapment of swimmers, wildlife and debris.
   CAUTION: Possible contamination. Do not use surface water for drinking. The installation shown could be used for sprinkler applications.

INSTALLATION

Flexible pipe is prohibited on suction pipe (inlet pipe). Unions or hose couplings can be installed near pump to facilitate removal for servicing or storage. A rubber hose installed between the water system and the house piping will reduce the noise transmitted to the house.
INSTALLING PIPING IN WELL
CAUTION: Dry-fit entire assembly to ensure proper fit before gluing or taping parts. Follow all proper gluing procedures as specified by the glue manufacturer. Always glue in a vertical direction whenever possible to prevent glue from dripping inside pipe or fittings Use pipe tape and pipe paste compound on all male threads.

PUMP PRIMING&STARTUP

CAUTION: Risk of burns. Never run pump dry. Running pump without water may cause pump to overheat, damaging seal and possibly causing burns to persons handling pump. Fill pump with water before starting.
WARNING: Risk of explosion and scalding. Never run pump against closed discharge. To do so can boil water inside pump, causing hazardous pressure in unit, risk of explosion and possibly scalding persons handling pump.

1. Remove the priming plug or tee from the pump and fill the pump, fill all piping between the pump and the well, and make sure that all piping in the well is full. If you have also installed a priming tee in the suction piping, remove the plug from the tee and fill the suction piping. (Fig. 1)
2. Replace all fill plugs, Open the faucet closest to the pump/tank a small amount to allow air to escape the system.
3. Power on! Start the pump.
4. If you don’t have water after 2 or 3 minutes, stop the pump and remove the fill plugs. Refill the pump and piping. You may have to repeat this several times in order to get all the trapped air out of the piping.
5. After the pump begins building pressure in the system, shut the faucet off. Let the pump build pressure until it shuts off. Check the pressure switch operation by opening a faucet or two and running enough water out to bleed off pressure until the pump starts. The pump should start when pressure drops to 30 PSI and stop when pressure
   reaches50 PSI. Run the pump through one or two complete cycles to verify correct operation. This will also help clean the system of dirt and scale dislodged during installation.
   If you were unsuccessful, please refer to Troubleshooting or call our customer service technical staff.

CARE AND MAINTENANCE

WARNING: Disconnect power and release all pressure from the system before attempting to install, service, relocate or perform any maintenance.
