Maintenance and repair
Careful and regular maintenance, inspections and revisions are necessary to detect and clear faults in time,
before consequential damages will happen. As individual operating conditions can not be defined for all ap-
plications the listed terms represent a general advice for undisturbed operation. Individual local conditions
(degree of pollution, load, etc.) must be taken into account when adjusting these terms.
What to do?
Time period
Terms
First inspection
After about 500 operating hours
½ year at the latest
Control of air circulation
and surface of motor
Depending on local environmental pollu-
tion
Relubrication (as option)
See name plate or relubrication sign
Main inspection
After about 10,000 operating hours
Once a year
Remove condensate water Depending on the local environmental
conditions
The necessary relubrication intervals for anti-friction bearings are different to these inspection inter-
vals. They have to be observed as well!
The motors up to size 315M are equipped as standard with anti-friction bearings with life-time lubrication.
From size 315MX upwards they are equipped with relubrication devices which can be ordered for smaller
motors as option. Information about bearings and relubrication can be found in the general installation,
maintenance and operation manual or on the name plate or relubrication sign.
Maintenance works (without relubrication) has to be done at standstill of the motor.
It has to be assured that the machine is secured against re-connection and labelled with an appro-
priate sign.
In addition the security advices and accident prevention regulations of the manufacturers for the use of oils,
lubricants and detergents has to be observed!
Adjacent live parts have to be covered or secured! It has to be assured that the auxiliary circuits like anti-
condensation heating are dead (zero potential).
For design versions with condensate drain hole please observe that the drain plug screw has to be lubricated
with a suitable sealant (for example Epple 28) before relocking.
Spare parts
Except for standard, commercially available and equivalent parts (like anti-friction bearings) only
original spare parts (see spare parts list) shall be used; this applies especially for seals and connec-
tion parts.
For spare parts orders the following information is necessary:
Spare parts name
Motor type
Motor number
Long term storage (more than 12 months)
Long term storage must be done indoors in vibration-free, dry rooms with temperatures not below -20°C and
not above +40°C. The storage environment must not contain aggressive gas, vapours, dusts and salts. Pref-
erably motors shall be moved and stored only in original packing. Storage and transport with motors standing
on their fan covers is not allowed. Additionally unprotected metal surfaces like shaft ends and flanges must
be protected with a medium for long-time corrosion protection in addition to the exisiting factory-provided
temporary corrosion protection. If there is a risk of motors being covered by moisture from condensation,
please provide precautionary measures against humidity. Than a special packing in airtight sealed plastic foil
is necessary or as alternative packing in plastic foil with desiccants. Please put desiccant bags in the termi-
nal box as well.
For the transport please use the eye bolts/attachment eyes of the motors together with suitable lifting acces-
sories. The eye bolts/attachment eyes must only be used for lifting the motors without additional mountings
like foundation plates, gears and others.
Motors with reinforced bearings are supplied with a transportation safety device. The transportation safety
device at the shaft end must only be removed during installation of the motor and before switching on.
Disposal
When disposing of the motors please observe applicable national law.
In addition please take care that all oil and grease is disposed according to the ordinance of waste oils
(Altölverordnung). They must not be contaminated with solvents, cold cleaners and paint residues.
