Personnel qualification
The personnel, who is carrying out assembly, operation and maintenence works must provide appropriate qualifications. The area of responsibility, competence and supervision of the personnel must be ensured by the operator. If personnel do not provide the required know-how, they must be trained or instructed accordingly. This device can be used by children aged form 8 years and above, as well as by persons with reduced physical, sensory or mental capabilties or lack of experience and know-how, only if they have been given supervision or instruction concerning use of the device in a safe way and if they understand the hazards involved. Children must not play with the device. Cleaning and user maintenance works must not be carried out by children without supervision.

Dangers, if safety instructions are not observed
Failure to observe the safety instructions may endanger persons, the environment and the system. Failure to comply with the safety instructions will result in the loss of any claims for damages.

Potential dangers include:

• dangers to persons due to electrical and mechanical effects
• failure of important functions of the system
• danger to the environment due to -leakage of liquids as result of a leak
• failure of prescribed repair and maintenence works

Safety-conscious work
Observe the safety instructions detailed in this manual, along with the current national accident prevention regulations. Should the system operator also have their own internalregulations, these must also be observed.

Safety instructions for the operator

• Any protection against contect with moving parts must not be removed or disabled, while the system is in operation.
• If liquids leak out, the must be collected or diverted in such a way, that no danger to persons or environment can arise.
• Hazards due to electrical energy must be excluded.
• For this purpose observe the instructions in local or general regulations (e.g. VDE etc.) and those of the local energy suppliers.
• If hazards sholud occur in the system due to hot or cold parts, these must be provided with a touch guard.
• Highly flammable substances must be kept away from the product.

Safety instructions for assembly

The system operator is responsible for ensuring that all assembly and maintenance works are carried out by qualified personnel. They must have previously familiarised themselves with the product, using the operating instructions. Conduction of works on the pump is only permitted when the system is shut down. Ensure that the device is securely disconnected from the power supply. Disconnect the device plug to achieve this. Prescribed instructions for shutting down the device can be found in the operating instructions. After completion of the works, all protective devices, such as touch guard, must be refitted in accordance with the regulations.

Unauthorised modification and use of spare parts
Modifications or alterations of the product are only permitted after prior consultation with the manufacturer. Only use original spare parts for repairs. Only accesories approved by the manufacturer can be used. If other parts are used, any liability of the manufacturer for the resulting consequences is excluded.

Inadmissable operating modes
If the pump is disconneted form the power supply, wait at least 1 minute before switching on again. Otherwise, the pump inrush current limit has no effect, which can lead to funtional errors or damage to any connected heating controller. The pump’s operational safety can only be ensured if it is used as intended. Point 4 of these instalaltion and operating instructions must be observed. Ensure compliance with the limit values detailed in the technical data.

Transport and storage
After receiving the product, inspect it immediately for damage caused in transport. If any transport damage is found, this must be claimed by the carrier.

Incorrect transport and storage can lead to personal injuries or damages to the product.

• Protect the product against frost, moisture and damage during transport and storage
• Only carry the pump by the pump housing, and never by the connection cable or terminal box
• If the packaging has been softened by moisture, the pump may fall out and cause several injuries

Intended use

The service water pump is used for circulation in detached and semi-detached houses with a pipe length of up to 50 m.

Product data
Technical specifications for Altech VVC Pump ECO15

Caution
Unpermitted pumped media can destroy the pump and cause personal injuries. Always observe the manufacturer’s instructions and safety data sheets!

Delivery range:

• Original installation and operating instructions
• Pump
• 2 flat gaskets
• Insulation
• Power plug

Operation

As soon as the pump is connected to the supply voltage, the LEDs in the control panel indicate which level is set.

• Level 1 – the first LED lights up (1)
• Level 2 – the first and the second LED light up (2)
• Level 3 – all three LED’s light up (3)

By pressing the button (4), the levels are switched through continuously.
The pump can be optimally adapted to the system by selecting of the most suitable characteristic curve. Flashing LEDs signal a fault.

Assembly

Warning
A check valve must be installed on the pump’s discharge side (primary side) to prevent pump backflow when the tap is opened.

A shut-off valve is installed at the suction point (secondary side) of the pump to simplify maintenance. A voltage-free assembly must be carried out with the horizontally positioned pump motor (the direction arrow on the pump body indicates the flow direction).

The circulation pump is installed in the pipe, usually directly in front of the service water storage tank, and in such a way that the water is pumped back from the central tapping point into the storage tank via the circulation pipe. When carrying out thermal insulation works, make sure that the pump motor and the electronics housing are not insulated.

Observe the permissible assembly positions:

Caution! Danger to life!

Improper assembly and improper electrical connection can be life-threatening. Hazards due to electrical energy must be excluded.

• Assembly and electrical connection may only be perfromed by qualified personnel and in accordance with the aplicable regulations (e.g. IEC, VDE etc.)!
• The type of current and voltage must comply wih the specifications on the type plate.
• Observe the regulations of the local energy suppliers!
• Observe the accident prevention regulations!
• Never pull on the mains cable.
• Do not bend the cable.
• Do not place any objects on the cable
• When using the pump in systems with temperature above 90°C, an appropriately heat-resistant connection cable must be used.
• There is a danger of personal injuries due to sharp edges or burrs during performing of assembly works
• Never transport the pump by carrying it by the mains cable.
• There is a danger of personal injuries due to dropping the pump.

Caution!
Mains voltage! Always observe the necessary safety measures, VDE regulations and local regulations.
Connect the mains cable to the pump as shown in the figure. The cross section of the cable must not be smaller than 0,75 mm2. When using fine-wire cables, use wire-end ferrules.

Filling and venting the system

Warning! Danger of burns!
Depending on the operating status of the system, the entire pump can become very hot.

NOTE!
Before putting the pump into operation, the system must be thoroughly flushed to ensure that no impurities or foreign bodies remain in the system. To vent the system, the pump must run at its maximum speed. Incomplete venting will result in increased noise during operation of the pump and the system.

Service and maintenance

The pump is almost maintenance-free. If the pump has not been in operation for a long time or if the system is heavily contaminated, the rotor may block. This is indicated by the upper LED flashing.
By removing the pump head (loosen the union nut and remove the pump head), the impeller is accessible and can be removed. This allows a blockage to be released and/or the pump to be cleaned. Then tighten the union nut with a torque of 30 Nm.
Before carrying out maintenance, cleaning and repair works, disconnect the system from the power supply and secure it against being switched on again by unathorized persons. At high water temperatures and system pressures,wait for the pump to cool down beforehand.
