The heater option includes the electrical heater, ambient blower,
bimetal thermostat, heater thermostat and limiter thermostat. All of the
thermostats are installed in the discharged enclosure airstream. When
the enclosure discharge air goes below 70°F, the ambient blower
thermostat shuts off the ambient blower. When the enclosure
discharge air goes above 85°F, the ambient blower thermostat turns
on the ambient blower.
When discharge enclosure air goes below 40°F, the heater
thermostat turns on the heater. When the discharge enclosure air
goes above 60°F, the heater thermostat shuts off the heater. See
wiring diagram on page 6.
1.
Attach the mounting bracket to the enclosure using the mounting hardware supplied
by Kooltronic.
2.
Route the power cord through the top cut out in your enclosure. Hang the unit on the
mounting bracket.
3.
Tighten the unit’s bottom flange to the enclosure using the hardware supplied
by Kooltronic.
The main component of the heat exchanger is the counterflow aluminum element through which the heat
transfer occurs.
Ambient blower draws ambient air from the bottom inlet through an aluminum mesh air filter, and the element,
and exhausts it through a discharge grill.
Cabinet blower draws cabinet air from the top inlet, blows it through the element and exhausts it through the
bottom discharge into the cabinet.
Kooltronic Heat Exchangers have been engineered to be installed easily. To avoid damaging your
Heat Exchanger, please read the following information before installation:
