M120 Product Line

High Efficiency R-410A Heat Pump
13 SEER — 3.5, 4, and 5 Ton Capacities

The MSH4BD-KA Series of

heat pumps offers exceptional
performance. The unit, when
combined with our engineered

coils or air handlers, offers a

full line of quality, split system
cooling equipment.

Features and Benefits

• Designed using galvanized steel – with a polyester urethane coat
finish. The 950 hour salt spray finish resists corrosion 50% better than
comparable units.

• Micro-Channel Coils – All aluminum coils in all models which provides
high corrosion resistance.

• Permanently Lubricated Motor – A heavy duty PSC motor for long lasting
reliability and quiet operation. Requires no maintenance and is completely
protected from rain and snow.

• Removable Top Grille Assembly – Allows ease of service from the top
without disconnecting fan motor leads.

• High Pressure Switch – Protects against abnormally high system
pressures. Auto-reset feature prevents nuisance service visits.

• Liquid Line Filter Drier – Included with unit, field installed.

• One Piece Top/Orifice – Designed for maximum airflow and quiet
operation.

• Easy Compressor and Control Access – Designed to make servicing
easier for the contractor, access panels are provided to all controls and
the compressor from the side of the unit.

• Composite Base Pan - Absorbs sound and is corrosion resistant. Composite
is also stronger and lighter than steel.

• Fixed Orice – Integrated in liquid line service valve for easy change-out.
