INSTALLATION SKETCHMAP

It is forbidden to install the motor upside down or tilt down to prevent water leakagefrom entering the motor and causing a short circuit and burning themotor.

USE OCCASION

• Condominium water tower pressurization
• Tap water pressurization
• Water heater pressurization

Please don’t install the pumps at the outlet of the water heater
Please don’t install the taps at the inlet of the water pumps

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.
2. Chem. condition: near neutral, non-cauterization, non-explosion similar water (glycol max-content: 30%).
3. If you want to use other kinds of liquids, please consult thefactory.
4. Max working pressure: 3 bar
5. The pump must be working at a rated voltage rangeof ±10%. Ifthevoltage is too low, the pump will come out low speed or hardly startup ,easily heating, lower head and pressure.

PURPOSE AND INSTALLATION PRECAUTIONS

1. The water pump is used for water supply and drainages of rivers, wells, boilers, etc., such as aquaculture, gardens, hotels, and pots. The boiler, canteen, high-rise building, and other pressurized water supply conditions are clean water. The water pump should be close to the water source, the water suction pipeline shall be as short as possible, and no air leakage is allowed. Otherwise, water cannot be absorbed.
2. The water pump shall be installed directly above the well as far as possible, but when the water pump can only be installed far away from the well, the maximum length between the pipe and the well depends on the suction head.Suction height is subject to dry season
   Suction height (m)| 8| 7| 6| 5| 4
   ---|---|---|---|---|---
   Horizontal piping length (m)| 3| 14| 26| 37| 49

▼When the water pump is installed together with the well and river, it is easy to absorb sand, and the end of the piping needs to be installed with a filtration device. Filters are available at the pump sales office.

3. It is strictly forbidden to run the water pump dry to avoid damaging the seal and causing the water pump to not work normally.
4.  The filter screen needs to be cleaned every 1 month.

MAIN FEATURES

JC pipeline pump is a high-pressure vortex pump. The motor and pump are coaxial, vertical, and horizontal dual-purpose integrated models. This series of products has two types of structure, namely ordinary type and automatic type. The common type is composed of a motor, main shaft, mechanical seal, impeller, pump body, fan blade, fan cover, wire box, and other parts. The automatic type consists of a common type equipped with an automatic water flow control device. The automatic control device is organically connected to the water pump so that the start and stop of the water pump are all controlled by the valve of the faucet.

SPECIAL WARNING

view

Before use, 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 place where to install the pump should be convenient for maintenance and change.
6. 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.
7. Current flow direction should be the same as the arrow on the pump.
8. 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.
