Pump Motors
OPERATING REMINDERS
A. Locate the pump/motor in a clean, dust-free
area. Most pool and jet pump motors are
open drip proof designs which circulate exter-
nal air for cooling. Air contaminants such as
sweeping dust and grass clippings may clog
internal air passages leading to overheating.
B. Protect from excess moisture. Don't hose
down the area around the motor when it is
running. Elevate the pump/motor if it is in
an area that is prone to flooding.
C. If an external motor cover is used, be certain
it does not trap moisture or allow cooling air
to recirculate.
D. Don't store or use chemicals close to the
motor.
E. A running motor that is too hot to touch is
not necessarily overloaded. Class B motors
have a maximum operating temperature of
130˚ centigrade (266˚ F).
F. If pool or jet pump motors are removed from
service at the end of a season, do not wrap
them tightly in plastic. Temperature changes
may cause condensation with detrimental
effects.
G. Thinner air at higher altitudes has less cool-
ing ability. As a rule of thumb, the next high-
er horsepower rating may be used at alti-
tudes above 3300 feet to compensate.
