specification plate or motor can
overload. Only qualiJ'led persons A _ _
with proper electrical
equtpraent and knowledge
should adjust variable pitch _
sheaves. Do not allow water to _ I _
get on the motor, as it will burn _V_
out the windings. _
Disconnect all electrical
power to the cooler and insure that belt
is not rotating before adjusting belt tension by
changing diameter of adjustable sheave. Adjust
belt tension only by adjusting motor bracket.
