Setup: Cadet Com-Pak Bath Owner Guide

Overview

The Com-Pak Bath is a compact fan-forced electric bathroom heater designed to deliver fast warmth during morning routines and other short heating needs. It is intended for fixed wall installation and combines a built-in thermostat, a timer, and a high-temperature safety shutoff in one assembly.

This guide is most useful for homeowners, installers, and replacement buyers who need a reliable bath heater that fits a wall can and is set up for either 120-volt or 240-volt operation depending on the model. The Com-Pak Bath is also a practical option when you want direct, localized heat without relying on a central system.

Detailed description

The Com-Pak Bath uses a fan and heating element to move warmed air into the room quickly. Its design includes a built-in thermostat on the right side and a timer on the left side, so the heater can run continuously at a set temperature or temporarily override the thermostat for a timed boost of heat.

Inside the unit are the heater element, fan and motor, and a high-temperature safety shutoff that interrupts power if the heater becomes too hot. The assembly installs into a wall can, and the grille finishes the front of the unit once wiring and mounting are complete. The Com-Pak Bath is not designed for ceiling, floor, or recessed wet-area installation.

The CB103T is the multi-volt version, which can be changed from 240 volts to 120 volts during installation. The CB132T is the multi-watt version, which stays on 240 or 208 volts but can be adjusted to different wattage settings before the heater is installed.

Safety

Safety depends on correct voltage, proper mounting, and keeping air passages open. The heater must be installed in a permanent location, used only as intended, and disconnected from power before any work is done on it.

• Keep bedding, curtains, furniture, papers, clothing, and other combustibles at least 3 feet away from the front and clear of the sides.
• Do not install directly above a bathtub or sink, and do not place it inside a shower stall.
• Do not install it in a floor, ceiling, behind a door, or under a towel bar.
• Never block the air intake or exhaust openings.
• Do not use the heater where gasoline, paint, or other flammable vapors or liquids are present.
• Do not operate the heater if it malfunctions; shut off power and have it inspected before reuse.
• Do not insert objects into the heater openings.
• Use the correct supply voltage listed for the model, since incorrect voltage can damage the heater and create a fire risk.
• Always turn off power at the main disconnect before servicing, cleaning, or wiring.

Setup and operation

Installation begins with confirming the supply voltage, preparing the wall opening next to a stud, routing electrical supply wire, and mounting the wall can so the arrows point upward. The heater assembly is then inserted into the wall can, wired to the supply, secured at the top, and covered with the grille. The unit must remain mounted with the element up.

For wiring, the ground lead connects to the grounding screw in the wall can. The remaining wires are connected according to the model and voltage in use. The CB103T requires a voltage change if it is being used on 120 volts, while the CB132T requires a wattage selection before installation. Multiple heaters can be wired on one 240-volt or 208-volt circuit if local code permits, the heaters are in the same room, and the circuit is not overloaded.

Once installation is complete, reinstall the grill, slide the knobs onto their shafts with the timer on the left and thermostat on the right, and restore power. To use the thermostat, turn it fully right, then back left until it clicks off at the desired comfort point. To use the timer, set the left knob to the desired minutes; while the timer runs, it overrides the thermostat, then returns control to the thermostat when time expires.

After the first start-up, the heater should be run on the highest setting for about 30 minutes. A brief smell or light smoke can occur as manufacturing residue burns off.

Cleaning and maintenance

The Com-Pak Bath should be cleaned at least twice a year or more often if needed. Power must be turned off before the grill is removed.

• Turn off power at the main disconnect panel.
• Allow the heater to cool completely.
• Remove the knobs and grille.
• Wash the grille in hot soapy water and dry it.
• Blow dust out of the heating element using a hair dryer or a shop vacuum set to blow.
• Vacuum the fan area.
• Reinstall the grille and knobs, then restore power.
• Do not lubricate the motor.

Any service beyond routine cleaning should be handled by an authorized service technician.

Troubleshooting

The heater includes clear built-in failure responses, especially when airflow is restricted or wiring is incorrect. Most issues can be traced to thermostat settings, blocked airflow, loose connections, voltage mismatch, or a tripped safety shutoff.

• If the heater smells after installation, it may be burning off manufacturing residue or dust inside the unit.
• If it does not heat, first check the thermostat setting and then check whether the high-temperature safety shutoff has tripped.
• If the breaker trips immediately, inspect for wiring shorts, an overloaded circuit, or a faulty breaker.
• If the heater blows cold air or stays cool, the heating element may have failed or the supply voltage may be wrong.
• If the fan does not spin, the motor may be defective or out of alignment.
• If the heater will not turn off, the room may need more capacity, or the thermostat may be faulty.
• If the safety shutoff trips repeatedly, check for blocked airflow and restore the required clearances.

To reset the high-temperature shutoff, turn off power, allow the heater to cool for about 10 minutes, remove any blockage, confirm the unit is clean, and press the reset button behind the plastic plug.

Warranty

The Com-Pak Bath heater includes a limited three-year warranty against defects from the date of purchase. Coverage is limited to repair or replacement and applies only when the heater has been installed and maintained correctly.

• Damage from incorrect installation or incorrect supply voltage is not covered.
• Damage from misuse, abuse, accident, alteration, or poor maintenance is not covered.
• Unauthorized accessories or components void the warranty.
• Replacement parts carry the same warranty terms as the original product and do not extend the original coverage period.

Pros & Cons

• Pros: Fast bathroom heat, built-in thermostat and timer, flexible wiring options, and a safety shutoff for added protection.
• Pros: The Com-Pak Bath is designed for compact wall installation and can be used in single-heater or multi-heater setups where code allows.
• Cons: Installation requires careful voltage selection and electrical knowledge.
• Cons: It must be kept clear of moisture zones and airflow obstructions, which limits placement options.
