Rietschle ZEPHYR VLP Serie Instructions D'utilisation Et D'entretien page 6

Application
The units ZEPHYR are suitable for use in the industrial field i.e. the protection equipments corresponds to EN DIN 294 table 4.
The ZEPHYR VLR can be used for the evacuation of a closed system or for a permanent vacuum from: 150 mbar (abs.) ➝ VLR 100,
200 mbar (abs.) ➝ VLR 250/ 300 and 250 mbar (abs.) ➝ VLR 400/ 500.
Warning – Suction of explosive gases
Any non compliance may lead to severe injury to persons and damage to the ZEPHYR may occur!
Dangerous mixtures (i.e. inflammable or explosive gases or vapours), extremely humid air, water vapour, aggressive gases or traces of oil and
grease must not be handled.
The standard versions may not be used in hazardous areas. Special versions with Ex-proof motors can be supplied.
Caution – Do not exceed the temperature
At non compliance severe damage may occur on the ZEPHYR.
The ambient and suction temperatures must be between 5 and 40° C.
Caution – Noise Emission
Potential risks for operating personnel.
When working permanently in the vicinity of an operating ZEPHYR, we recommend wearing ear protection to avoid any damage to hearing.
Setting up (picture and
Warning – hot surfaces
Pumps that have reached operating temperature may have a surface temperature at position (Q) of more than 70°C.
Do not touch these hot surfaces (see also warning signs)!
The oil filler ports (H), oil sight glasses (I), oil drain plugs (K) must all be easily accessible. The cooling air entries (E) and the cooling air exits (F)
must have a minimum distance of 20 cm from any obstruction. The discharged cooling air must not be re-circulated.
Note
The ZEPHYR can only be operated reliably if they are installed horizontally.
For installations that are higher than 1000 m above sea level there will be a loss in capacity.
Installation (picture and
For operating and installation follow any relevant national standards that are in operation.
1. Vacuum connection at (A).
The air handled can be exhausted into the atmosphere through the exhaust silencer (ZSZ) or by utilising a pipe connection and pipeline.
Note
Long and/or small bore pipework should be avoided, as this tends to reduce the capacity of the pump.
2. The lubricating oil (recommended brands see under servicing) for the gears and bearings should be put into the oil filler port (H), until the oil
level shows at the middle of the oil sight glasses (I). After filling make sure the oil filler port is closed.
3. The electrical data can be found on the data plate (N) or the motor data plate. The motors correspond to DIN/VDE 0530 and have IP 54
protection and insulation class B or F. The connection diagram can be found in the terminal box on the motor (unless a special plug connection
is fitted). Check the electrical data of the motor for compatibility with your available supply (voltage, frequency, permissible current etc.).
4. Connect the motor via a relevant direct on-line motor starter. It is advisable to use thermal overload motor starters to protect the motor and wiring.
All cabling used on starters should be secured with good quality cable clamps.
We recommend that motor starters should be used that are fitted with a time delayed trip resulting from running beyond the amperage setting.
When the unit is started cold, overamperage may occur for a short time.
Warning – electrical installation
Danger to life through unprofessional electrical installation!
The electrical installation should only be made by a qualified electrician under the observance of EN 60204. The main switch must be provided
by the operator.
Initial Operation (picture and
1. Initially switch the compressor on and off for a few seconds to check the direction of rotation against the direction arrow (O).
2. Connect the suction pipe at (A).
3. Vacuum regulating valve:
The vacuum can be adjusted by turning the regulating valve (C) according to the symbols on the top of the regulating valve.
