Instruction Manual
Automatic Booster Pump
TP8-P Series
TP8-P Series
ISO 9001 Certied

Operation Conditions:
1. Ambient temperature: Max. +40°C
2. Liquid temperature: +4°C ~ +40°C
3. Inlet pressure: Lower than the pressure
switch ON setting. ( See Specication )
4. Operating pressure: Max. 6 kg/cm²
OPERATION
1. Make sure connect the correct voltage.
2. Remove the water plug and pour water into
the pump and suction piping ,then secure
the plug.( FIG.1 )
In suction lift application, please follow below
instruction ll up water to the chamber
1. Remove 4 screws and water cover
2. Remove check valve
3. Fill up water
3. Insert a screw driver cross into the shaft slot ,
and turns the shaft 2-3 rounds to check if the
pump runs normally , then open one faucet
on the delivery side , the turn the power
switch ON.( FIG.3 )
4. After the power switch on, the motor
should turn immediately . After a few
seconds, the water should be delivered .
5. If the water does not be delivered immedi-
ately turn the power OFF. Repeat step 2 and
set power ON/OFF continuously to make
the suction piping be lled with water.
6. Once the water is pumped out, close the
faucets on the delivery side to check the
automatic stopping and pumping opera-
tion.
IMPORTANT NOTE
1. Use the correct voltage and wiring by the
connecting diagram. Motor must be
grounded in compliance with applicable
electrical code to avoid accident.
2. please use a sturdy foundation and bolt the
pump to it securely.
3. Be sure to arrange earthling or circuit
breaker against electric leakage.
4. The pump should be installed as close as to
the reservoir or well to avoid the low
eciency due to the long suction pipe.
5. The location must be dry with good ventila-
tion and adequate space.
6. Do not run without water actually pump-
ing. Do not operate hot water (more than
60 °C ), or the other liquid except normal
water.
7. Be careful not to allow the foreign matter
(chips, dirt, sand, glue, etc) into the pump,
or the will damage and shorten the life of
pump.
8. Piping joints should be tted carefully to
prevent leakage.
a. Leakage in the suction piping will cause
the pump does not function well.
b. Leakage in the discharge piping will
cause a high frequency ON /OFF motor
operation while all the faucet and valves
are closed.
9. Keep the faucets opened fully to get more
ecient operation. Never keep continuous
operation under the condition of half open.
10. TO avoid your furniture damage, do not
install the pump on ceiling, carpet or any
place close to electrical appliance, outdoor
installation must covered by tent.

TROUBLE SHOOTING
(Turn the power switch OFF before xing.)
1. MOTOR FAILS TO START OR RESTART
AFTER A SHORT-TERM RUNNING
The overheating protector is mounted direct-
ly on the motor windings. It will stop the
motor automatically when the motor
temperature is up to abnormal, and restart
the motor after the temperature back to
normal in 20 minutes.
a. Check the electrical power source, fuse,
and circuit breaker.
b. Check if pump is locked by rust or foreign
objects.
c. Check if the ventilation of the location is
bad for causing the overheating of motor.
2. PUMP CYCLES FREQUENTLY WHILE ALL
THE FAUCETS AND VALVES ARE CLOSED:
a. Check and x the leakage in discharge
piping, faucets, and valves.
b. Clean pump check valve (FIG.5-8) which
may be locked by foreign objects.
3. PRESSURE SWITCH FAILS TO FUNCTION
The pump's pressure switch has been set
accurately. Please do not try to adjust except
by qualied personnel.
a. If the motor does not start after any of the
faucets or valves are opened, adjust the
pressure setting screw to the "+"
direction (counterclock- wise) until the
motor starts.(FIG.4)
b. If the motor fails to stop after all the
faucets and valves are closed, adjuts the
pressure setting screw to the "-" direction
(clockwise) until the motor stops.(FIG.4)
c. Repeat step (a) and (b) until the pump
work normally.
Coverage of Application:
1. Directly and automatically supply water to
the building without roof water tower.
2. Automatically increase pressure as soon as
the insucient water pressure in top oor.
3. To be used on supplying water for washing
machine and heater if water pressure is too
low.
4. To drain accumulated water for civil and
architecture engineering, to be applicable
to the skyscraper villa, pond and farm.
5. To be used on circulating water for garden
and on supplying water for auto car-washer.
