California Proposition 65 Warning

WARNING This product and related accessories contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.
Deep Well Installation
Under certain conditions, horizontal multistage pumps can develop extremely high pressure. Install a pressure relief valve capable of passing entire pump flow at 75 PSI.
**Do not allow pump, pressure tank, piping, or any other system component containing water to freeze.
Freezing may damage system, leading to injury or flooding. Allowing pump or system components to freeze will void warranty.
NOTICE: Support pump base to avoid strain on casing adapter or pump. Lack of support can damage adapter or pump.
Figure 2 shows casing adapter bolted directly to pump body.
Shallow Well Installation
NOTICE: If no foot valve is used, install 1” check valve in horizontal line.
Priming the Deep Well Pump
To prime pump, completely close the priming valve located just below the suction opening by turning screw clockwise. This valve will be left closed during operation in a deep well installation. See Figure 1. Figure 1 – Deep Well Installation
Close regulator adjusting valve, located on end of regulator, by turning stem clockwise. See Figure 1.
Remove priming plug from top of regulator valve. Fill with clean water. Replace plug. See Figure 1.
Start pump and run a few moments.
If pressure does not build up, remove priming plug and refill with more water. All of the trapped air in pump body was not removed.
Restart pump.
When pump is completely primed and builds up pressure, slowly open the regulator valve, (turn counter-clockwise), and observe the pressure reading on the pressure gauge.
When the pump reaches a point where it will lose prime, cavitation noise can be heard.
The best, or correct, pressure gauge setting is approximately 3 pounds higher than the pressure gauge reading was when the pump started to lose prime.
If pump loses prime, repeat the priming procedure above and this time open regulator valve only until the correct pressure reading is reached.
If a vacuum gauge is available, screw it into the 1/8” AVC tapping on front of tank body. Adjust regulator until 20” of vacuum is registered on the gauge. Tighten locknut on
regulator. This method will give maximum performance of the unit.
Figure 2 – Well Casing Adapter bolted directly to pump
Figure 3 – Shallow Well Installation
HMSC pumps come equipped with pressure switch set to operate within a 20-40 PSI range. HMSD, HMSE, and HMSF pumps have 30-50 PSI pressure switches. When pump is used with precharged tank in system, set tank pre-charge at 18 PSI with a 20-40 PSI switch; set tank precharge at 28 PSI with a 30-50 PSI switch. Check tank precharge annually with an ordinary tire gauge. Pre-charge is set with no water pressure on system.
Priming the Shallow Well Pump
CAUTION 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  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.
To prime the pump, completely open the priming valve located just below the suction opening on the tank body by turning the valve stem counter-clockwise all the way until it stops.
This valve may be left open during operation as a shallow well pump with no jet. See Figure 3 and “NOTICE” below.
Remove priming plug from top of elbow (see Figure 3), and fill with clean water. Replace plug.
Start pump and between 45-60 seconds. If water is not being pumped, turn off pump and repeat priming process.
NOTICE: If a bolt-on jet is being used, after pump is primed, close the priming valve during operation as a shallow well pump.
Service – Draining for Winter
CAUTION   Do not touch an operating motor.
Modern motors are designed to operate at high temperatures. To avoid burns when servicing pump, allow it to cool for 20 minutes after shut-down before handling.  When the pump is to be disconnected from service, or is in danger of freezing, it should be drained. The pump has a drain plug which must be removed. Remove the priming plug to vent the pump.
If pump and motor are damaged due to freezing, the Warranty is void.

MOTOR SWITCH SETTINGS
Your motor terminal board (located under the motor end cover) should look like one of those below. If the motor can operate at either 115 or 230 volts, it is set at the factory to 230 volts. Do not change motor wiring if line voltage is 230 volts, or if you have a single voltage motor.
CAUTION   Never wire a 115 volt motor to a 230 volt line.
Plug Type Voltage Selector Figure 4: Voltage set to 230 volts, Plug Type**
Voltage is factory set to 230 volts. To change to 115 volts:

1. Make sure power is off.
2. Pull the voltage change plug off of the tabs.
3. Move the voltage change plug to the 115 volt position. The plug will now cover 2 metal tabs and the arrow on the plug will line up with the 115V arrow on the label (see Figure 5). Figure 5: Voltage set to 115 volts, Plug Type
4. Attach the incoming power leads to the two outer screws on the pressure switch as shown in Figure 4.
5. Attach the ground wire to one of the grounding connections, shown in Figure 4.
6. If there are other wires, they should be capped.
7. Reinstall the Motor end cover. Figure 6: Voltage set to 230 volts, Dial Type

WARNING Hazardous voltage. Can shock, burn, or kill. Connect ground wire before connecting power supply wires. Use the wire size (including the ground wire) specified in the wiring chart. If possible, connect the pump to a separate branch circuit with no other appliances on it.
WARNING Explosion hazard. Do not ground to a gas supply line.
WIRING CONNECTIONS
WARNING Fire hazard. Incorrect voltage can cause a fire or seriously damage the motor and voids the warranty. The supply voltage must be within ±10% of the motor nameplate voltage.
NOTICE: Dual-voltage motors are factory wired for 230 volts.
If necessary, reconnect the motor for 115 volts, as shown. Do not alter the wiring in single voltage motors.
Install, ground, wire, and maintain your pump in compliance with the National Electrical Code (NEC) or the Canadian Electrical Code (CEC), as applicable, and with all local codes and ordinances that apply. Consult your local building inspec- tor for code information.

Connection Procedure:

1. Connect the ground wire first as shown in Figure 4. The ground wire must be a solid copper wire at least as large as the power supply wires.

2. There must be a solid metal connection between the pressure switch and the motor for motor grounding protection.
   If the pressure switch is not connected to the motor, connect the green ground screw in the switch to the green ground screw under the motor end cover. Use a solid
   copper wire at least as large as the power supply wires.

3. Connect the ground wire to a grounded lead in a service panel, to a metal underground water pipe, to a metal well casing at least ten feet (3M) long, or to a ground electrode provided by the power company or the hydro authority.

4. Connect the power supply wires to the pressure switch as shown in Figure 4.
