The outdoor housing of the
unit has been re-engineered.
Removing only a few screws
allows complete removal of
the compressor housing top
panel, side panel and corner
post. This gives the mechanic
quick, unrestricted access to
the compressor, all controls
and components located
within the compressor
compartment. Or, just a
single panel can be removed,
depending on the requirements
of the service call.

The large control panel has abundant space for the controls you choose. The components are intelligently
arranged and laid out in a logical fashion which is easy to understand and work with. Each control and wire is
clearly marked with a name or number as shown on the wiring diagram which is permanently affixed to the
control panel door.

RUSS-SAVER

The initial cost of quality refrigeration equipment is a substantial investment. But the costs of
installation and operation are also formidable. Rising to the challenge, Russell engineers

have designed the RUSS-SAVER system to meet the highest standards of performance and
reliability while effectively addressing the problem of these profit draining costs.

· REDUCED INSTALLATION COSTS

The installation of a refrigeration system which uses RUSS-SAVER requires a smaller refrig­erant charge than equipment which uses other types of low ambient controls. As the more
expensive zero ozone depleting refrigerants become the refrigerants of choice, the reduced
charge requirements provided by RUSS-SAVER affords

saving benefits.

substantial and immediate cost

· REDUCED OPERATING COSTS

The most expensive part of an
the compressor. Day and night, year after year, the cost of electricity to operate your equip­ment is unrelenting

The RUSS-SAVER system is designed to take advantage of reduced ambient conditions dur-
ing non-peak requirements. As the outside air temperature decreases, head pressures are
allowed to drop. This action results in the compressor pumping more refrigerant per stroke
while requiring less energy; saving

. These dollars are pulled right from your bottom line.

substantial amounts of energy and

your

money!

· RUSS-SAVER even saves money during high ambient conditions.

The sub cooling loop provided in the condenser of the RUSS-SAVER condensing unit
increases the system efficiency 1/2% for each degree of sub cooling provided, thereby mak­ing the compressors job easier. Combined with Copelandʼs energy efficient DISCUS compres­sors, RUSS-SAVERʼs efficiency saves you money during summer operation and even more
during the winter months.

RUSS-SAVER

To estimate your average monthly savings:

1) Select a RUSS-SAVER system that meets your refrigeration requirements.

2) Determine the Average Annual Outdoor Air Temperature from the table below.

3) Using the Projected Monthly Savings graph, locate the system nominal horse power at the
bottom of the graph.

4) Go straight up to the appropriate Annual Average Outdoor Temperature curve, then go
horizontally to the left to determine your Estimated Monthly Savings.

5) To calculate your Estimated Monthly Savings for energy costs other than $0.10 KWH, divide
the Estimated Monthly Savings by 0.10 and multiply the result by your local electric utility rate.

6) To determine your Estimated Yearly Savings, multiply the Estimated Monthly Savings by 12.
