1. If you want to mend or maintain, please close the two-end taps
and let the pump cool down. Then you can maintain, avoiding
scalding or the steam or hot liquid, which come out from the inside
pressure system.
2. Cut off the power supply.
3. Only expert staff can install or perform maintenance.
4. If the above measures are not working, pls contact your local dealer

PUMP EXHAUST
①Before using, please exhaust first.
②If the pump continues working one week for hot water circulation,
please exhaust it one time per week.
Exhaustion methods:
At first, cut off the power and close the outer
tap, then slowly twist the exhausting screw,
and use
the screwdriver to turn the pump shaft 15-30
seconds later. There will be some
liquid coming out. After exhaustion, please
tighten the screw on time.
Note: To avoid being scalded by steam or hot water during
exhausting, please don't face the vent directly.
MAIN USE
Shield-type pipeline pump is suitable for floor heating systems, like as
Automatic pressured and circulated for water separator, water collector,
boiler, and hanging boiler; matching for water-cooled air-conditioning and
center air conditioning system; water supply for the washing machine when
lower pressure; increase the flux and pressure for the tap water, supply
and circulate liquid for industrial equipment. Part of the pump body is made

of copper or stainless steel materials, which more sanitary household
water.
MAIN FEATURES
1. This pump adopts a shielding set of stainless steel and keeps water
away from electrical machinery completely. A mechanical seal is not
required, thus completely solving pump leaking. Adopted the ceramic
bearing, stainless steel shaft, friction-resistant, corrosion-resistant,
automatic water circulation, it can be used for cooling lubricating motor,
also for lubricating the bearing and the motor won’t be damaged even
highest head working. If the method is on the right way, there is no need to
maintain it for three years, good quality and long time use.
2. This product adds a timer. The user can set the time period, and the
pump will run in the corresponding time period.
3. The noise of the pump is very low. It’s most suitable for indoor lowest
noise occasion installation and use.
4. All the inside motor materials adopted the heating-resistant, so it can be
completely used in a hot-water circulation booster system.
WORKING CONDITION
1. Medium transportation temperature: 2℃- +95℃
2. Max circumstance temperature: +40℃
3. Medium condition: clean, no solid substance, no mineral & oil substance,
no stickiness.
4. Chem. condition: near neutral, non-cauterization, non-explosion similar
water (glycol max-content: 30%).
5. If you want to use other kinds of liquids, please consult the factory.
6. Max working pressure: 3bar
7. Min. inlet pressure:
a. At +50℃0.05 bar
b. At +95℃0.3 bar

- 5 -
All above are only suitable for altitudes 300 m, much higher 100 m by 0.01
bar adding. To avoid air-causticity, which makes noise, you should keep
min. Pressure limitation.
The pump must be working at a rated voltage range of ±10%. If the voltage
is too low, the pump will come out low speed or hardly start up, easily
heating, lower head and pressure.
PRODUCT ACCESSORIES
1. Electric pump;
2. Water pipe sealing tape * 1;
3. DN20 to DN15 internal connector * 2;
4. DN15x50cm bellows * 2;
5. Filter screen.

SPECIAL WARNING
Before using, the pump must be reliable earth touch. Don´t change the
three-core wiring plug to avoid power leakage. To make sure everything is
safe, please u must install some security measures, such as the power
leakage broker or electric shock blocker and so on.
1. Earth wiring and nil wiring must be
separated. If there is no reliable earth
wiring, the accident will be no
business with us.
This type of water pump´s plug feet,
if "L" is Live Wiring, "N" is Nil Wiring,
and the longest one is "E" earth
touch wiring. Customers must pay
attention to the connection to the
plug when they install the three-core
socket.
Here we absolutely forbid u to unite
the Nil Wiring and Earth Wiring
together, which can make power
leakage dangerous.
2. Don´t use a blanket to cover the motor or the pumps. Keep ventilation to
avoid fire danger.
3. If you install our pump outdoors, please u should do some protection
measures. Or it will decrease the using life span because of the sun-baked
and raining. Worst it can cause an electric shock accident. If you install our
pump indoors, please avoid water spilling to make an electric shock; don´t
install it inside the bathroom to avoid the cream and water going inside.
4. After a few years of normal use, if you hear any sound in the motor,
please replace the internal shield components timely to prevent the danger
of electric shock hazard by water leakage.

PRECAUTION
1. When connecting to the power supply, let the pump work for several
seconds to inspect whether the start-up is normal or not. But don’t let the
pump work with no water for a long time to affect the ceramic bearing span.
Special the self-auto water pump, in case of no water suddenly, u should
pay more attention to avoid unnecessary loss.
2. Pls pay attention to the water drop on the wood floor or easily moisture
goods when exhausting the air or maintenance.
3. Don’t touch to avoid scald when our pump using in the heating system.
The wiring materials must be heating-resistant.
4. Before installation, make sure the pipeline is welding well and clean. If
there have foreign substances, welding clinker, or dirt, they will damage the
water pump.
5. The filter screen needs to be cleaned every 1 month.
6. The place where to install the pump should be convenient for
maintenance and change.
7. We suggest that you pls separately install the check valve at the inlet or
outlet for maintenance. Then it can avoid the leaking water drop to the
water pump and the junction box.
8. Current flow direction should be the same as the arrow on the pump.
9. When the direction of the junction box isn’t right, u can lose the
hexangular screw and return the motor to the right position. Pls don’t
damage the rubber gasket, then re-tighten the screw and check whether
the seal gasket is ok or not.
