CONDENSATE EVAPORATOR
The
MPM/QMPM
is designed to operate in an environment of 75
°
ambient and 55% relative humidity. When
the conditions are applicable for condensation such as high temperature and high humidity, a large capacity
condensate evaporator has been installed in the
MPM/QMPM
to ensure proper evaporation.
POWER TOGGLE SWITCH
The toggle switch turns the power ON or OFF and is accessible through a slot at the back of the
MPM/QMPM-
36
and
MPM/QMPM-48
cabinet.
