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 units ZEPHYR KLR produce simultaneously pressure and vacuum between 0 and the maximum limits, which are shown at the data plate (N).
They may be operated continuously.
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 ZEPHYR KLR may not be used in hazardous areas.
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. For temperatures outside this range please contact your supplier.
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 glass (I), oil drain plug (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.
Caution – Do not operate without the limitation valves (ZBD) and (ZUV)
Do not exceed the permissible maximum pressure or vacuum (see data sheed) severe damage may occur on the KLR.
The ZEPHYR KLR may not be operated without the standard limitation valves fitted.
1. Vacuum connection at (A) and pressure connection at (B).
Note
Long and/or small bore pipework should be avoided as this tends to reduce the capacity of the pressure/vacuum 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 plug-connector (J) if fitted or 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
Maximum number of starts per hour: 12 (KLR 80), 10 (KLR 140)
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) and pressure pipe at (B).
