Introduction

To ensure safe operation of your KleeBlower compressor/vacuum pumps, please read this instruction manual and pay particular attention to instructions marked with the following signs:

DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING: Indicates a potentially hazardous situation which, if not avoided, will result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which, if not avoided, will result in minor or moderate injury.

Application The KleeBlower is a complete unit ready for immediate installation either as a vacuum pump or as a compressor. It is designed for handling air and other non-flammable, non-corrosive and non-explosive gases only.

Vacuum and compression pressures
The drive motor can be loaded with total differential pressures given in the technical data. Blowers with limited performance curves in the high pressure range should be fitted with the relative pressure relief valves in order to avoid an overload of the motor. Pressure relief valves can be mounted directly on the outlet and the vacuum relief valves directly on the inlet of the blower.

Temperatures
The permissible ambient temperature and gas temperature at the inlet is -10 to +40 ºC. The maximum allowed humidity is 80%

Operation

Transport and storage
When lifted by a crane, Kleeblower units must be secured at the eye bolt on the pump casing.
Pay attention to the load-bearing capacity of the hoisting equipment. See previous page for weight data.
The rolling contact bearings should be regreased or enclosed. They should be replaced with new ones if more than four years have elapsed between delivery and machine commissioning under favourable circumstances
(storage in a dry, dust free and vibration free room). Under unfavourable circumstances, this period is considerably reduced.

Installation
A) Kleeblower units can be installed in vertical, horizontal or slantwise position. However take bearing load into consideration when installing the blower: The following examples are for your reference:

• CORRECT
• INCORRECT

B) An awning is required for the blower if it is installed outdoors, avoiding motor from being damaged.
C) The base with which the blower is fastened must be 3 times as heavy as the blower.
D) Install a filter onto the suction inlet of the blower to prevent it from sucking impurities if the suction inlet is not connected to a pipe.
E) Keep ventilation gratings and openings clear. The direction flow is indicated by arrows on the motor end shield and casing.

WARNING: On installation or after maintenance, it is needed to check that the pump rotation is correct as specified by the arrows. Do not operate the blower with the inlet or outlet blocked or restricted, direct or via nozzles.

F) Piping needs to be installed to the same level as the central line of the blower outlet and inlet.
G) Piping needs to be installed without becoming narrowed, expanded or being bent at 90 degrees to avoid affecting blower’s operation efficiency.
H) Piping needs to be fastened independently. Do not mount the piping to the blower flange or casing to avoid damaging the blower.
I) The sectional-area curve of the pipe diameter should be no less than 60% of the sectional-area curve of the blower outlet.
J) Since the pressure and current of the blower are in direct proportion, it is necessary to enlarge the diameter of the wind suction/extraction piping to avoid overloading of the motor.
K) Keep the fan motor of the blower away from walls or any stuff at a distance of 50mm to avoid affecting the heat dissipation efficiency of the motor, preventing it from overheating.
L) Since the pressure and current of the blower are in direct proportion, it is necessary to install a pressure relief valve at the air suction/extraction port to avoid overcurrent failure of the motor. The pressure relief valve listed below can used in both compressor and vacuum applications.

• Mounting:
• Outline:

M) Pressure and air friction can easily build up heat around the outlet of the blower. To lead away the heat, an iron pipe at minimum 1 meter is thus needed to be connected to the outlet.
N) On the discharge side, the cover, impeller and silencer housing must not come into contact with flammable materials (i.e. wood)
O) The flow noise is reduced by build-in silencers. In the case of free air intake or exhaust, the noise can be further reduced by attaching additional silencers. In order to reduce noise emission even further, these units should not be attached to components that conduct or radiate sound (such as thin walls, metal plates etc.). If necessary provide intermediate sound- absorbing layers.
L) Serial and parallel connected blowers feature:
Serial connection: (Pressure increases)

Pressure = 90% of (Model A + Model B) Air flow = Model A

Parallel connection (airflow increases)

Pressure = Model A or Model B Air flow = Model A + Model B

CAUTION: Blowers of different horse power can not be connected with one another.

Electrical connection

DANGER: The electric power must be disconnected before any work is performed on the equipment.

A) The system voltage and frequency must be the same as stated on the stamp plate. ±5% voltage and ±2% frequency deviations from the rated values are permitted without the necessity of derating the output. The joints should be arrange and connected according to the circuit diagram in the terminal box. The protective earth conductor should be connected to the terminal

CAUTION: High surface temperatures of more than 70ºC can occur at the blower. No heat-sensitive parts, such as standard cables or electronic components, must be attached or make contact to the surface. If necessary, protection measures must be provided!

B) The rated motor current applies for +40ºC air inlet and ambient temperatures. However at temperatures of +25ºC a 6% higher motor current is permissible.
C) Select motor circuit-breakers to match the rated motor current. Where frequency drives are used as power supply, high frequency current and voltage harmonics in the motor cables can cause electromagnetic interference. Therefore shielded motor cables are recommended.
D) Exceeding the operating speed (see stamp plate) worsens performance with respect to noise and vibration, and also shortens the life of bearing grease and the bearing replacement interval. To prevent damage arising from excessive speeds, it is advisable to consult the supplier concerning speed limits. Generally rule is approx. 65Hz maximum.

Commisioning

CAUTION: If the blower is started up without being connected or fastened, for example for test purpose, the initial torque of the motor may cause suddenly movement resulting tilt of the blower.

Note: for safe operation of the blower the following conditions as a minimum must be observed:
A) The blower is assembled and operated in accordance with the data on the stamp plate and information supplied by this manual. (voltage, current, frequency, connection model and type of protection)
B) When frequency drives are used, operating speeds are not to be exceeded according to permitted data on stamp plate. Generally rule is approx. 65Hz maximum.
C) The blower is properly assembled, aligned and connected to piping or hoses as appropriate.
D) The elevation of the installation location is taken into account when adjusting the pressure control valves
E) The direction of the rotation of the blower is as specified.
F) All fastening screw/bolts, fasteners and electrical connections are tightened.
G) The earthing and equalizing potential bonding connections have been made properly.
H) All measures have been taken to protect against contact with moving or energized parts.

CAUTION: The inlet must be arranged so that no foreign elements are sucked in and ejected through the outlet. (hazard for eyes and skins) When air is sucked in from the atmosphere, the inlet must be covered with protective devices (i.e. gratings) in order to prevent foreign elements including parts of the body and clothing being sucked in. Covers which prevent contact with active or rotating parts are not to be opened during operation.

Maintenance

DANGER: Before any work is performed on the blower or equipment, especially covers over moving parts are removed, the blower should be properly disconnected from the power supply or frequency drive. Wait until the rotation of the blower is stopped completely. Do not connect the power supply or frequency drive until the blower has been completely assembled.

Cleaning
A) When there are any deposits of fluff or dust, clean the entire surface of the KleeBlower unit.
B) When required by operating conditions, dismantle by removing screws or nuts from blower cover. Do not lose these nuts; they will be required for reassembly! Remove and clean the cover. Clean impeller and housing after carefully covering rolling-contact bearing. Reassemble in the reverse order.

WARNING: After fastening screws/bolts are removed, some parts are just in centring fits. Even during proper dismantling it is still possible that some heavy parts suddenly become loose and drop off, possibly causing injuries and damage. Take suitable measures to secure all parts being worked on.

Lubrication
A) The following applies in connection with normal operating conditions (air intake and ambient temperatures +40ºC max. and permissible total differential pressure): After approximately 20.000 hours of operation or after two and a half years at the latest, the rolling-contact bearings and adjacent spaces should have the old grease removed and be recharged with new grease. About 50% of the free space in the rolling-contact bearings and about 65% of the adjacent grease spaces should be filled with grease.

B) Closed rolling-contact bearings should be replaced with new ones; their adjacent grease spaces are not filled with grease.
C) The information given concerning bearing life and grease life applies to only this product. Always avoid mixing different types of greases.
D) Type of grease used in bearings is Mobilgrease XHP220
