Danger plates (see page 42)

The plates fitted on the compressor unit are part of the machine; they have been applied for safety purposes and must not be removed or spoiled for any reason.

3.0 PLACING

The AIRPRESS compressor should be placed in such way that all points, destined to carry it will really do so. Take also care of a horizontal position.

The engine should get sufficient cooling air; so never cover the ventilating openings. Place the compressor in cool dust free and well-ventilated surroundings with clean air. Never place the compressor in a room where will be sprayed or in an environment with aggressive substances in the air. Good ventilation is essential to discharge the cooling air. Mind that the drain tap for condensation water (16), the oil drain tap (17) and the oil level glass (8) will always remain attainable. We suggest to leave a space of approximately 50 cm for ventilation and maintenance.

The temperature in the compressor room must not be lower than +5^ or higher than +40^ .

Notice: Insufficient air supply, too high temperature and fouling of the air filter reduce the efficiency of the compressor considerably.

3.1 ELECTRIC CONNECTION

At the factory the machine is already fully equipped with cables. The machine now has to be connected to your own electricity supply. Connect the machine to a separate group. Beware that voltage and amperage of your electric circuit meet the needs of the motor. Use only cables with the right diameter. The factory suggests to use cables of at least 2.5 qmm (for motors over 10 HP: 4 qmm).

It is well advised to place a main switch between the compressor installation and the electric circuit, so you can shut off all the electricity before maintenance. Use only skilled personnel for electric connections.

Before first use first read chapters 3.2 and 4.0.

3.2 AIR CONNECTION

Best use for connection of the compressor to an air circuit a flexible hose, to isolate fibrations from the machine. The diameter of the hose must meet the connection of the ball cock.

4.0 FIRST USE

1 Check if the instructions mentioned above have been executed.
2 Check the oil level of the compressor. The oil level has to be on the red dot on the inspection glass (8). Possibly oil has been lost during transport. Fill if necessary with AIRPRESS compressor oil through desaeration motor case/oil refill cap (11).
3 Check tension on the V-belt. At the right tension the V-belt can easily be turned by hand approximately 45 degrees. If necessary improve tension (see chapter 5.0 point 5).
4 Let the compressor run for a short while so you can check if the turning direction is correct (see arrow on belt protector (3)). If the motor runs in the wrong direction, switch two phases of the electric plug. Disconnect electricity!
5 For daily operation of the compressor see chapter 5.0.
6 After 20 working hours fix the head bolts. See below: TIGHTENING MOMENTS BLACK PUMPS BUILD ON: K 100-300 t/m K 300-600 head bolts: 27 Nm. (from 2002) K 300-700 t/m K 500-700 S head bolts: 55 Nm. (from 2002) K 500-1000 t/m K 500-1500 S head bolts: 94 Nm. (from 2002)

Check if the pressure switch is turned off. Connect electricity. Turn on the pressure switch. If the air pressure in the air tank is lower than the 'switch on pressure', the compressor will turn itself on, until maximum pressure has been reached. Is the pressure in the tank higher than the 'switch on pressure' the machine will not start, but will be stand by to start when the pressure drops too low.

When switching of the compressor, first switch the pressure switch to "0" before turning off the electricity. The pressure switch takes the pressure off the compressed air circuit, so that the compressor can run freely when it starts again. This prevents damage to the motor.

The electric motor of your compressor is protected against burning by a thermal overload device. This device turns off the motor automatically, if the motor should get overloaded, or if one phase should fall out. By pressing the reset button on the thermal overload device after a short time, the compressor will function again.

6.0 MAINTENANCE

Before carrying out any maintenance jobs it is obligatory to stop the machine and disconnect it from the power mains.

1 After the first 50 operating hours and then every 250 operating hours the oil should be refreshed. Therefore, turn out the oil draintap (17) and also remove the desaeration motor case/oil refill cap (11). Collect the oil. If the oil does not come out any longer, turn in the oil draintap (17) and fill with fresh oil through the desaeration motor case/oil refill cap (11) up to the red dot on the oil level glass (8).

Always respect the regulations in force for disposing of old oil!

2 Regularly drain condensation water. The drain tap is situated at the bottom of the tank. Draining with pressure in the tank is the easiest way.

Condensate must be disposed of in conformity with the local regulations in force (not in the sewer!).

As an alternative you can place an oil/water separator. Ask your dealer for information.

3 The oil level should also be checked regularly. The oil level must be on the red dot on the oil level glass (8). If necessary refill with AIRPRESS compressor oil (article code 36380) through the desaeration motor case/oil refill cap (11).

Checking daily can prevent a lot of troubles!

Use oil of the same type as that already in the machine; do not mix different types of oil!

4 The air filter element should be cleaned or changed regularly. This change depends on the amount of fouling and should be done more often in dusty situations and less often in a clean situation. For cleaning the filter element, take out the filter container with the filter. Then clean the filter by blowing off the dust.

5 The V-belt should be checked after every 1000 hours. At the right tension, the V-belt can easily be turned 45 degrees by hand.

If tension is too high, strong corrosion will occur or eventually the spindle of motor or pump may break. At too little tension, the efficiency of the compressor decreases considerably.

Tightening the V-belt goes as follows:

Dismount the belt protector (3).

Unscrew the fastening bolts on the motor sledge.

Remove the V-belt. Place the motor at the right distance from the pump.

Make sure that the pulley of the motor runs in the same line parallel with the flywheel on the pump (see drawing). Tighten the fastening bolts and replace the V-belt. Worn V-belts should be replaced by new ones with the same size.

Note: Regular maintenance of your compressor will increase durability and reliability.

7.0 FUNCTIONING (see functional diagram)

The pressure switch controls the compressor. In the factory the pressure switch is set to start and stop the machine at a specific pressure. When the maximum pressure has been reached, the pressure switch works as follows:

• Types with thermal overload device: the compressor stops and relieves the pressure from the internal air circuit. If pressure drops below the starting pressure, the motor wilt start and the pump delivers air to the tank.
• Types with star-delta switch: the compressor stops and the internal air circuit is being relieved from its pressure through the electric valve (14). If pressure drops below the starting pressure, the following happens: the electric valve is open and the compressed air is being released. A time relay leaves the compressor to run freely for a few seconds in star position. Then the compressor switches to delta position and the electric valve is being excited and closes. Now the pump is working and pressure is being built up in the tank until the maximum pressure is reached.

Valid for all Airpress compressors model K:

Sound power level: Lw(A) = 99dB(A) (re 1 pW).

Sound pressure level: Lp(A) = 87dB(A) (re 20~ Pa

Measured according to NEN-EN 12076.

8.0 POSSIBILITIES OF FAILURE

1 When pushing the pressure switch the compressor does not run:

*blown fuse - renew the fuse
tank at pressure
motor broken - repair/renew
thermal failure - reset thermal relay (see point 2)
defective pressure switch - repair/renew
- blown control current fuse - renew fuse
- defective star-delta switch - consult repair service

2 Repeating thermal failure:

*blown fuse - renew fuse
* loose wire - repair
pressure switch does not relieve - repair/renew valve air circuit
too low voltage - remove extension cable or use heavier
- defective electric valve - repair/renew
* overloading - reduce loading

3 Compressor keeps blowing off air:

• defective non-return valve - repair/renew

4 Too little air production:

• dirty air filter - clean/renew filter
• V-belt too loose - tighten V-belt
• defective valves - renew

5 Leaking safety valve:

• pressure too high - set pressure switch
• defective safety valve - renew

* general failures

- failures only with types with star-delta switch

Note:

to obtain conditioned dry air it is recommended to use a compressed air dryer in combination with a pressure reducing valve for a constant operating pressure. Ask your dealer for more information.
