Connect the vacuum line to the vacuum pipe connector (6). The outlet air can exit the pump through the exhaust
silencer (2), or can be piped away through an additional pipe connector.
The vacuum performance will be reduced if the vacuum line is either too restrictive or too long.
The electrical installation should only be made by a qualified electrician and according to EN 60204 and the
regulations of the local power supplier. The main switch must be provided as disconnecting device by the
operator.
The electrical data can be found on the motor nameplate (20). The connection diagram can be found on the inside of the
terminal box (unless a cable and plug is fitted). Check the motor data with available power supply (voltage, frequency,
maximum current).
A suitable cable strain relief must be provided (e.g. via a cable clamp).
The pump shall be protected against short-circuit with circuit-breaker. We recommend also that any motor protection
switch should be fitted with a time delayed trip. This is due to the brief high ampere draw when starting from cold.
If the connecting cable is damaged or broken, it shall be displaced by the manufacturer or a qualified electrician to
prevent electrical hazard.
The appliance must only be assembled or used according to its protection type.
Storage:
The VTE should be stored at a relative air humidity valve from 30% to 80% and a temperature from -20°C to + 60°C.
Above 80% relative air humidity suitable additional packing with a drying agent should be used.
Initial operation (B 1):
The vacuum port (6) should be open or not restricted; otherwise the vanes may break if the pump rotates in the
wrong direction.
Check motor direction by briefly starting the pump and comparing the direction of rotation with that on the motor
nameplate (20).
Vacuum regulation valve: (Pos 3 – Accessories): The setting of the vacuum regulation valve determines the maximum
vacuum as described in the operation instructions.
During operation:
Pumps which have reached their operating temperature may have a surface temperature up to 100°C. To avoid
burning, do not touch.
Do not manually transport the pump whilst in operation.
The internal pump parts are self-lubricating. To avoid damage, do not allow lubricants to enter the pump.
Regularly clean the air filter and check the condition of the vanes (see service information).
Noise emission:
The use of ear protection for longer exposures to operating pumps is recommended.
Service and maintenance (B1):
During service the pump must be isolated from the power source and made certain that re-connection is not
possible. To prevent burning injuries due to hot parts, servicing should not be undertake on pumps which are at
operating temperatures. To ensure satisfactory opeartion, only use original service parts.
In the case of devices without thermal protection, you must check whether they are suitable for continuous
operation in accordance with the manufacturer's catalogue.
If you ignore this, it can result in overheating leading to the motor blocking.
In this case, you must immediately disconnect the device from the mains supply, since there is a fire risk.
