WARNING:

off and unit is unplugged. This is for your safety.

Annual Maintenance

• Oil bearings. The blower bearings (RMMB14 only) and cooler
motor in this unit should be oiled with a few drops of non-detergent
20/30 weight oil once each year. The motor does not need oil if it
has no oil lines for oiling. Motors that have no oil lines are lifetime
oiled at the factory and require no further oiling for the life of the
unit.
CAUTION:
Do not over oil. Over oiling can cause motor burn
out, due to excessive oil getting into motor winding.
• Change Pads. Pads should be replaced once or twice a season,
depending upon the length of the season. At the beginning and at
mid season a clean pad is more absorbent and effi cient and will
deliver substantially more cool air.
• Check belt and belt tension. This applies only to model RMMB14
which is belt driven. Models MMB10 and RMMB12 have direct
drive motors. Check the belt for any cracks or wear and replace if

cooler at least once a week. Keeping fresh water in the pan will
help prevent scale and mineral deposits accumulation on the pads.
Always drain all of the water out of the cooler when not in use for
prolonged periods, and particularly at the end of the season.
• Unplug unit from power supply during extended periods of
non-use.
• Cover unit or store inside when not in use.
By following the operating, installation, and maintenance suggestions
as outlined, you can get many years of effi cient and satisfactory
service from your cooler. In the event additional information is
desired, your dealer will be more than glad to assist you in every
possible way.
