OB-SERVE PERSONAL PROTECTION MEASURES!In this connection make sure to observe the safety information on page 50.DAMAGE TO UNITWhen the fan is at a standstill and the unit heater control valve (water, steam orrefrigerant) is open, the temperatures inside the unit reach a rough equivalent of theinlet temperature of the heating medium (normally around 90 °C). This causesdamage through deformation of plastic parts (particularly to plastic dropleteliminators, humidifier honeycombs etc.).Furthermore, fan and motor bearings with permanent lubrication may be damagedat temperatures above 80 °C. Many electric built-in components (frequency convertersetc.) may only be operated at temperatures up to a maximum of 40 °C – also seethe relevant manufacturer's instructions.The following maintenance and inspection steps must be carried out:• Check that fans are securely mounted.• Check fans for dirt, damage and corrosion.• Check that anti-vibration mounts are functioning correctly.• Check that belt guards are functioning correctly, clean if necessary.• Check impeller for out of balance.PR-2006-0019-GB • Subject to modifications • Status 05/2009 55
