Features

• Molded Lexan® fan guards
• Coils have copper tubes with aluminum fins, mechanically-
	bonded for efficient heat transfer. The coils are dehydrated	Application
	and sealed
•	Textured aluminum cabinet	Models BB are compact, wall-mounted units whose low
•	Knockouts are conveniently located for refrigerant lines	height makes them ideal for undercounter reach-in or drawer-
•	Screws are hardened, stainless steel with a bright	type fixtures.The unit draws air in at the bottom and discharges
		out the front. An optional air deflector is included and can be
	zinc plating
		mounted over the center of the fan to direct air up and out. The
• Expansion valve mounts inside the cabinet and		deflector can be field-formed to direct the air where needed,

•	Motors are thermally protected and	preparation fixtures. An S-type mounting angle is included
		to position the unit 3/4” off the wall which gives optimum air
	permanently lubricated
		circulation and performance.
•	Master units include the basic unit plus factory mounted
		The BBM (medium temperature) model is designed for 35°
	expansion valve, solenoid, and temperature control. Also
		to 40°F fixture temperature with off-cycle defrost. The unit
	right-hand piping extended 8” - 12” outside the housing,
		is designed to operate at 10° to 17° TD and 16 hours per day
	sealed and pressurized to 20 - 30 PSI. A 1/4” OD liquid feed	compressor run time.
	to slave is included	The BBL (low temperature) model is designed for 0° to -10°F
• Slave units include the basic unit plus factory mounted		fixture temperature, and has automatic electric defrost. The
	expansion valve with left-hand piping extended 8” - 12”	unit is designed to operate at 8° to 15° TD with 18 hours per
	outside the housing, sealed and pressurized to 20 - 30 PSI	day compressor runtime. The BBL has an incoloy sheath heater
		embedded in the bottom fin surface for efficient and fast
Sweat inlet connection to reduce leaks		defrosting. A drain pan heater is included to insure complete
