8 Residual risks

•

Sharp edges & corners

There is a substantial risk of injuries due to sharp edges and corners of coil and casing. Make

sure to wear reliable protection during any handling of the unit and maintenance activities.

•

Drip tray

Ensure the drip tray is empty before lowering or disassembling. The weight of any leftover water

or ice could injure the operator if the drip tray fell open accidentally.

•

Side plates

Removable side plates may only be opened by qualified staff. Ensure the side plates are

properly secured after closing.

•

Fans

Rotating fans can cause injuries to fingers. Never operate fans without the mounted protection

grid and take care of loose clothing. Switch power off before any maintenance.

•

Electrics

Power must be switched off before any work or maintenance on electrical parts of the unit.

Secure the unit against unintentional switching on.

•

Burns or frostbite

(Distributor) tubes can be extremely cold, whereas defrost heater elements can get very hot.

Use reliable protection.

•

Working fluids

Working fluids might be toxic and/or flammable. These substances may only be handled by

qualified staff while taking all necessary precautions and following any applicable regulations.

•

Fan vibrations

Continuous fan vibrations can cause material failure and hence a risk of injury or damage due to

loose parts. Therefore vibrations must be reduced to a minimum at all times.

9 Troubleshooting

Fault

Possible cause

Required action

Fan motor not functioning

No power supply

Check/restore power supply.

No control signal (EC motors)

Check/restore control signal.

Fan blade blocked

Remove obstruction.

Fan motor burnt

- Check for fan blade obstructions.

- Check thermal protection device.

- Replace fan motor.

Excess motor noise

Defective fan motor bearing

Replace fan motor.

Excess vibrations

Loose fan fasteners

Tighten fasteners.

Unbalanced fan blades

Replace fan blades.

Insufficient capacity

Heat exchanger coil dirty/blocked

Clean coil.

Coil partly blocked by solid ice

- Check defrost cycle settings.

- Check defrost heaters.

- Perform 100% coil defrost to remove all ice.

Fans not (properly) functioning

Check fans.

Refrigerant supply/pressure insufficient

Restore refrigerant supply/pressure to reference values.

Refrigerant leakage

Refrigerant containing parts damaged

- Stop fans.

- Close refrigerant supply.

- Repair leak.
