RECEIVING THE THERMOELECTRIC COOLER
Inspect the thermoelectric cooler. Check for concealed damage that may have occurred during shipment. Look
for dents, scratches, loose assemblies, etc. Damage evident upon receipt should be noted on the freight bill.
Damage should be brought to the attention of the delivering carrier -- NOT to nVent Equipment Protection -- within
15 days of delivery. Save the carton and packing material and request an inspection. Then le a claim with the
delivering carrier.
nVent Equipment Protection cannot accept responsibility for freight damages; however, we will assist you in any
way possible.
HANDLING & TESTING THE THERMOELECTRIC COOLER
TEST FOR FUNCTIONALITY BEFORE MOUNTING THE THERMOELECTRIC COOLER TO THE ENCLOSURE.
Refer to nameplate for proper electrical current requirements, then connect power cord to a properly grounded
power supply. Minimum circuit ampacity should be at least 125% of the amperage shown in the design data
section for the appropriate model. No other equipment should be connected to this circuit to prevent overloading.
Operate the thermoelectric cooler for ve (5) to ten (10) minutes. No excessive noise or vibration should be
evident during this run period. The ambient and enclosure fans should be running.
PRINCIPLES OF OPERATION
The thermoelectric cooler is congured for direct power application through the input connections on the
supplied wire harness. The thermoelectric cooler can be used for cooling or heating and is automatically
controlled by the included electronic control. Note the fan wiring will not change to match the peltier module
wiring. The fan wiring is the same regardless of whether the thermoelectric cooler is congured for cooling or
heating.
MAINTENANCE
Beyond occasional inspection for dust or dirt buildup no special maintenance should be required.

INSTALLATION INSTRUCTIONS
1. Inspect thermoelectric cooler. Verify functionality before mounting the thermoelectric cooler, see
HANDLING & TESTING THE THERMOELECTRIC COOLER on page 2.
2. Using the cutout dimensions shown in this manual, prepare the air openings, and mounting bolt
hole pattern for the enclosure.
3. Remove ground screw to prevent interference with cutout during installation.
4. During installation, remove power/alarm harness and grommet from the shroud to prevent the
wires from interfering with the enclosure cutout.
5. Mount the thermoelectric cooler on the enclosure using the mounting fasteners provided.
6. Reinstall the power/alarm harness and grommet into the thermoelectric shroud.
7. Reinstall the ground screw with the customer supplied grounding cable.
8. Refer to the top of the nameplate for the electrical requirements. Connect the thermoelectric
cooler to a properly grounded power supply. Class 2 or SELV power source is required for fans.
