Maintenance

Before starting maintenance work, always switch off the main switch and repair
switch(es) and lock them in the OFF position.
Wait until the fan runs down to a standstill before opening the inspection door.

Lubricatable fan bearings must be lubricated with lithium-saponified grease every
2500 operating hours.
Maintenance-free bearings have life-long lubrication and are labeled accordingly.

Standard three-phase motors are maintenance-free.
Comply with the manufacturer's instructions for special motors.

Retension the Vee-belts for the first time after 50 operating hours. Thereafter,
check tension at regular intervals depending on operating conditions, but every
4 months at the latest.

Always replace the belts of a multi-groove drive as a complete set.

The drive motor of the KG 40-100 Standard is mounted on a rocker. To tension the
drive belt, slacken the locknut on the tensioning screw, tighten the tensioning
screw until belt tension is correct and retighten the locknut.

The drive motor of the KG 160/250 and 630-1000 can be moved on its rectangular-
section mounts. To tension the drive belt slacken the securing screws of the
rectangular-section mounts and the locknuts of the tensioning screws. Tighten the
tensioning screws until belt tension is correct, while checking that the belt pulleys
are in perfect alignment.
Tighten the locknuts and the securing screws.

Correct Vee-belt tension:
The Vee belt is correctly tensioned if thumb pressure applied midway between
motor and fan shaft deflects the belt approximately 15 mm.

Make sure that the vee-belt pulleys are in correct alignment.

At regular intervals, check for foreign-matter accretions and clean.
Clean the heat exchangers by:
- Vacuum extraction
- Blowing clean with compressed air
- Spraying with water or steam

Make sure the pressure of the air/water/steam for cleaning is not in excess of
5 bar.

Check the condensate drains.
Open the siphon, clean and refill with water.
Use commercially available scale removers to clean the drip-separator sections.

Do not oil the louver-flap shaft.
Blow clean with compressed air: no other maintenance is required.
