replace if necessary.  Check the ten-
sion on the belt. A 3 lb. force should 
defl ect the belt 3/4 inches (see Fig. 
4).  Readjust belt if needed.

•  Clean pump.  Cleaning the pump 

is necessary once a year at start-up.  
For your safety, turn unit off and unplug unit and pump.  Remove 
the pump from the mount slot.  Remove the base of the pump (Fig. 
5).  Clean the pump and turn the impeller to ensure free operation.  
Remove the pump spout and check for any blockage.  After clean-
ing, reinstall the base onto the 
pump.  Press fi rmly to make sure 
it is secure.  Reattach the pump 
to the mount in the cooler using 
the plastic retainer to ensure that 
the pump will not overturn.  Do 
not forget to replace the spout 
and water delivery tube onto the 
pump outlet.

•  Drain water.  It is recommended to drain the water from the 

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.

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.

•  Oil bearings.  The blower bearings (M401A & RM401A 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.

  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 models 

(R)M401A which are belt driven.    Models M201A and (R)M301A 
have direct drive motors.  Check the belt for any cracks or wear and

  Note:  Do Not Overfi ll.  Fill water to a maximum height of 2 1/2 

inches (approximately 1 inch from the top of the bottom pan).  If 
using a garden hose, the fl oat will need to be adjusted to maintain 
this water level.  This can be accomplished by bending the fl oat 
rod.
