The flow switch can be disassembled or replaced by using a “Din 1810 Form A No.40 68-75 hook wrench” or other similar pipe wrench to unscrew the “Locking Ring (Part No. 22-4)”

The filling of suction piping and pump chamber must be very carefully to ensure no any air inside. Trapped-air will cause pump low discharge / pressure, and resulting abnormal operation. Trapped-Air evacuation can be accomplished by opening all discharge valves, or unscrewing the discharge side “Priming Plug (Part No. 21-2)” during pump operation.

PROBLEM – Pumps fail to start when the discharge devices are opened.

Test Schematic Status

Voltage is normal

Go to test “A-2".

A-1

Input Voltage Check

No power

Check the controller power source and circuit breaker.

Voltage is normal

1: Turn the power off, and check if the motor rotate manually. 2: If the motor or pump casing is overheating, the motor

winding or pump casing thermostat might be tripped due to motor overloading or pump dry running. The motor will start running automatically, when the motor winding or pump casing temperature back to normal.

Motor still running

1: Make sure if the flow switch is activated due to the leakage

of discharge piping or devices. 2: Clean the inlet check valve to ensure the flow switch can

back to normal position. 3: Replace the flow switch.

Motor Stops

The pressure switch function is normal.

Motor still running

1: Make sure the inlet water source is enough. 2: Check the suction piping for air-locked or leakage which

result low pump output pressure. 3: Lower the pressure switch setting. 4: Replace the pressure switch.

PROBLEM – Pumps cycle frequency or unstable under “Power ON”

Test Schematic Status

Motor back to normal

1: Avoid small discharge piping leakage or operation which

will cause unstable flow switch ON/OFF switching. 2: Recharge pressure tank air up to 1~1.2 kg/cm

3: Replace the flow switch.

Installation and Piping

For stable operation, please mount and bolt the booster pump securely. The

installation place must be dry with good ventilation and adequate space for

future maintenance and service. A proper shelter is required for outdoor

installation; exposure to rain will damage the insulation of electrical wiring.

The pump should be installed as close as to the reservoir or well. For hot

water (40~90ºC) pumping, negative inlet pressure application is required to

avoid cavitations. Piping joints should be fitted carefully to prevent leak. Leak in the suction piping will cause the pump suction capacity lost, while leak in the discharge piping will cause a high frequency ON/OFF motor operation while the faucets valves are closed.

*3 Parts or materials for hot water models only.

*2 Parts for 50 Hz models.

*1 Parts for 60 Hz models.

3. Protection rubber films within the center of suction/discharge flange gaskets (Part No. 15 & 18) muse be removed during installation.

Be careful not to allow the foreign objects (PVC adhesive gum, dirt, sand etc) into the pump, otherwise the pump will be damaged and shortened the life.

It is recommended to use a strainer to prevent that.

Check the voltage and wiring of the motor power according to the connecting diagram shown below or inside the cover. Be sure to arrange earth or circuit breaker against electric leakage in accordance with local government electrical

code.

The pump thermal protector (Part No. 31) is designed to protect the pump from dry run. It is also used to prevent hot water pumping which will damage the pump structure. The electrical power will be cut off after several minutes

while dry run occurs, and will be turned on periodically. Shut off the electrical power manually is recommended during the water shortage period to save the energy.

7. An auto-reset thermal protector is equipped with the motor winding. Power

will be cut off when the motor winding temperature is abnormal, and will restart when the abnormal temperature back to normal.

1. Before set the power on, the pump chamber and suction pipe must be filled with water in accordance with the following:

2. Insert a crossed screwdriver into motor shaft end, and turn the shaft several turns clockwise to check whether the pump can be rotated freely. If not,

disassemble and clean the pump chamber.

Double check the voltage and wiring of the motor power and then turn the

power switch ON. Open faucet or water appliances on the discharge piping side. The water should be delivered after several seconds.

4. If the water does not be delivered after several minutes, turn off the pump immediately. Repeat step 1 to pour water into the pump and suction piping,

and switch power ON and OFF continuously.

5. Once the water is pumped out, close and open the water appliances on the

discharge side repeatedly to check automatic ON/OFF operation.

Measure the motor current and check with the data shown on the nameplate.

If the current is over, check the voltage again.

7. When re-start the pump after long term shut down, please repeat step1~6 to

ensure the normal operation.

The pressure switch set is designed inside the control box. In general, the pressure has been set by factory properly to meet most situations. However, for some special cases, when the pump cannot operate normally, it can be adjusted easily. Please check the trouble shooting procedures, and read the following instructions carefully before to do it. For pressure adjustment, first remove the switch cover, and loose the lock nut counterclockwise by using a 12mm wrench.

1. Motor fails to stop

It is because of the pressure setting too high. By using a flat-end screwdriver, turn the screw counterclockwise slowly, until the motor stop; then, turn an extra small rotation, about 5 degrees. Finally, check if the motor can start normally.

2. Motor fail to start

It is because of the pressure setting too low. By using a flat-end screwdriver, turn the screw clockwise slowly, until the motor start, then an extra small rotation, about 5 degree, is added. Finally, check if the motor can stop normally.

3. After the pressure setting, screw the lock nut, and put the cover back.

◎

For the negative inlet pressure application ( inlet water level is below the pump input ), remove the priming plugs (Part No. 21-1 or 21-2), and pour water into

the pump via priming hole completely. Then, secure the priming plugs back.

◎

For the positive inlet pressure application ( inlet water level is higher than pump input ), loose the priming plug (Part No. 21-2), and then secure it after the water drain out from the priming hole.
