Mitsubishi Electric PAC-646BH-E Base Pan Heater 120W 230V

Product Description

The MITSUBISHI ELECTRIC PAC-646BH-E is a base pan heater designed for ductless mini-split outdoor condensing units. Operating at 230 volts and drawing 120 watts, this heater keeps the base pan free of ice accumulation during cold-weather operation. Ice buildup in the base pan can restrict drainage and interfere with defrost cycles, leading to reduced efficiency and potential equipment damage. This part is installed by HVAC technicians as part of cold-climate accessory kits or as a direct replacement when the original heater fails.

This base pan heater is used on outdoor units in residential and light-commercial ductless split systems. It is specifically listed for the MXZ-2C20NA2 outdoor condensing unit. Applications include installations in cold climates where outdoor ambient temperatures regularly drop below freezing. The heater helps maintain proper drainage clearance at the base of the unit during heating season operation.

Key Features

• Rated at 230 volts and 120 watts for reliable low-draw continuous heating
• Prevents ice accumulation in the outdoor unit base pan during cold-weather operation
• Supports proper condensate drainage and protects defrost cycle performance
• OEM part designed for direct replacement in compatible Mitsubishi Electric outdoor units

Compatibility

Installation Notes

Base pan heaters are installed by licensed HVAC technicians. Disconnect and lock out all power to the outdoor unit before accessing internal components.
