Features and Benefits
The PRO3 Top Mount packaged refrigeration systems combine evaporator and condensing unit into one unit —
simplifying installation and reducing refrigerant charge, which saves time, money and energy. Not only that, it’s
environmentally friendly.
The PRO3 Top Mount is designed to maximize storage area inside a cooler or freezer and is ideal for small- to
medium-sized restaurant and convenience store applications where holding temperature is the primary goal.
If greater pull-down capacity is required, see the PRO3 Side Mount packaged refrigeration system (model PST).

Ease of Installation and Service
• Installation takes a fraction of the time required for a split
system: no piping or loose components to install, refrigerant is
pre-charged at factory and a field superheat adjustment is not
required (see installation manual for more information)
• No drain line required: indoor models come with a
condensate evaporation pan
• Flexible design allows for multiple installation methods:
optimized for indoor use, but outdoor models available with
weatherhood installed. Outdoor models also come with:
crankcase heater, drain line heater and fan-cycling for head
pressure control
• Maximizes storage area in a cooler or freezer: evaporator grill
mounts flush on a standard 4" or a recessed 5 1/2" ceiling panel

Ease of Use
• System is factory-assembled, evacuated, charged, run-tested
and wired; no additional components or refrigerant charging
required; most models come with a 26" power cord ready
to plug-in
• Controls preset for typical applications: +35° F for coolers, -10° F, for
freezers and are easy to adjust (019L6 set for 0° F)

Energy Efficient | Environmentally Friendly
• Energy Solutions® energy-efficient motors from InterLink™
Commercial Refrigeration Parts:
• PSC motors optional in both condensing unit and
evaporator section
• EC motors optional in evaporator section only
• Reduced refrigerant charge: system uses approximately
10 percent* of refrigerant required for a comparable
split system

Most indoor PRO3 Top Mount
systems come standard with a 26"
power cord and 3-prong electrical
plug for quick installation and
start-up which may eliminate
the need for a field installed
disconnect. See the data tables
in this brochure for electrical
receptacle specifications.

The PRO3 Top Mount
evaporator grill sits
flush in a standard 4"
thick ceiling panel.

New EC Motors for PRO3 Packaged Refrigeration Systems
Introducing the most-energy efficient motor available for packaged refrigeration systems. Choosing energyefficient motors for your packaged systems can provide significant energy savings and lower operational costs.
Additionally, because these motors can help reduce heat load (and system run-time), they can improve the
reliability and longevity of refrigeration equipment.
Electronically Commutated (EC) motors even further improve energy efficiency and equipment reliability. EC
motors by InterLink™ are up to 75% efficient – that’s a 51-59% increase over shaded pole motors and a 30-35%
increase over PSC motors. As with PSC motors, you save money both directly from a decrease in motor watts and
also from a reduction of heat gain into the refrigerated space.
Permanent Split Capacitor (PSC) motors can significantly lower your energy costs. PSC motors average 30-35%
higher efficiency than shaded pole motors and offer dual energy savings by reducing motor watts and heat gain
into the refrigerated space.
