NOTE: Some of the information in this manual may not apply if a special unit was ordered. If additional drawings for a special unit are necessary, they have been inserted. Contact nVent Equipment Protection if further information is required.
WARRANTY AND RETURN POLICYhttps://hoffman.nvent.com/en/hoffman/warranty-information
RECEIVING THE THERMOELECTRIC COOLERInspect 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 file 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 COOLERTEST 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 five (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 OPERATIONThe thermoelectric cooler is configured 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 configured for cooling or heating.
MAINTENANCEBeyond occasional inspection for dust or dirt buildup no special maintenance should be required.

INSTALLATION INSTRUCTIONS1. 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.

WIRINGRecommended wire gauges for wiring:
Power and earth ground leads 14 AWGAlarm Leads 20 AWG
Connect the controller and TEC as shown in the wiring diagrams. Use a protected power supply or inline fuse; 20 amp limit for 24 Vdc unit and 10 amp limit for 48 Vdc units. Ensure that higher potential input power conductor is connected to the (VIN+) terminal and lower potential is connected to the (VIN–) terminal. Input power conductors shall be no longer than 10 feet.

SETUPCooling and heating temperature setpoints are factory set to 77 F/25 C for cooling and 59 F/15 C for heating.These setpoints can be changed by adjusting the 4-position dip switch on the printed circuit board assembly (S1). See Table 1 - Cooling and Heating Setpoints.
Note: The heating function includes a disabled position.

OPERATION OF ELECTRONIC CONTROLEach time power is applied, the controller will step though a start-up sequence. This consists of indicating the current cooling and heating settings, and turning on the cooling and heating function such that proper operation of the TEC can be verified. The sequence is as follows:
1. The blue cooling LED blinks for a half second ON and half second OFF for the appropriate number of times (see Table 1 - Cooling and Heating Setpoints).
2. The red heating LED blinks for half second ON and half second OFF for the appropriate number of times (see Table 1 - Cooling and Heating Setpoints).
3. The TEC ramps up in cooling mode for 5 seconds. The blue cooling LED flashes rapidly.4. The TEC ramps up in heating mode for 5 seconds. The red heating LED flashes rapidly.
The controller will command the TEC to cool if the temperature read by the thermistor is above the cooling setpoint, and to heat if the temperature is below the heating setpoint. If heating is called for, the controller will automatically reverse the DC voltage to the TE modules. During cooling, H+ is a higher potential than H-. During heating, H- is a higher potential than H+. The controller logic will apply power to the peltier chips. If the temperature read by the thermistor is between the cooling and heating setpoints, the controller will be in a standby mode with no power applied to the TEC modules. The external fan runs only in cooling mode.The normally open (NO) alarm dry contact will close when an alarm occurs, including loss of power. The normally closed (NC) contact will open when an alarm occurs.
