Duo-Pak

Multi-Circuit Condensing Unit
(Equal to Two Condensing Units)

The Duo-Pak condensing unit will perform the functions of two
condensing units. It will replace either a 99M (1 hp) or 69M
(3/4 hp) medium temp condensing unit, and a 249L (2-1/2 hp) or
199L (2 hp) or 149L (1-1/2 hp) condensing unit. This combo unit
will supply refrigeration to both a walk-in cooler and a freezer.

Duo-Pak is available as PCL (pre-charged with refrigerant and
up to 40' of pre-charged lines provided), PC (pre-charges with
refrigerant for up to 50' line length) or PR (pre-assembled
remote system shipped with nitrogen holding charge).

Duo-Pak Advantages:

• Installer only has one unit to mount.

(reduces the amount of space required).

• Single point electrical.

• Easy access electrical panel.

• Timer for freezer is pre-wired and mounted in electrical box.

• Compressors are branch circuited and individually fused.

• Crank case heaters (outdoor models) only come on when unit

is in off-cycle (reduces excess heat that the compressor has

to overcome during warm conditions and reduces energy

consumption overall).

• Shipping cost is reduced.

• Outdoor models come standard with headmaster valves.

(optional on individual units) Note: headmaster valves allow

refrigerant to bypass the condenser coil during cold weather

conditions by maintaining a minimum head pressure.

• Color-coded wiring.

• All units have standard liquid line sight glass.

• Energy efficient PSC fan motors are standard.

• Two large 14" fan blades.

• Individual oversized receiver tanks allows capacity for

additional refrigerant during pump down when long line runs

are required on remote units.

• Units ETL listed to UL Standard 1995.

• Outdoor unit provided with weatherproof housing.

• Indoor unit provided with special indoor housing.
