RB SERIES ENGINEERING GUIDE
Internally Mounted Solenoid Valve Option
When variable speed circulating pump systems are designed, low
pressure drop (high Cv) solenoid valves are specified at each unit
to vary the pump according to flow required. It is important that
these valves be low pressure drop to avoid unwanted pump watts.
This option factory installs this valve inside the unit.
Secondary Drain Connection Option
Some local building authority’s interpretation of codes require more
condensate overflow protection than standard microprocessor
based condensate sensors offer. In these areas a full secondary
drain pan might be required causing both increased cost and
unit service access issues. In many of these cases a secondary
drain connection option can be added to the unit to pass this local
interpretation of condensate drain redundancy. This option adds a
second PVC drain connection to the drain pan at a higher level.
Phase Guard
Factory mounted phase guard device is available to protect the
compressor against loss of phase.
Disconnect
An optional factory mounted, internally
wired disconnect is available to avoid
scheduling problems with the electrical
contractor. Other features include:
• Non-fused, ‘dial’ type switch with
“on/off” position
• Compact design
• “Lockout/Tagout” feature to keep the
unit “off” during service
Low Ceiling Height Requirement (Horizontal 006-012)
Utilizing a raised drain pan, the condensate drain trap on horizontal
models 006 through 012 can be made within the height of the
cabinet. This allows the RB Series to be installed without any
additional ceiling height, or in areas where ceiling height is at a
premium. The RB Series 006-012 models have the lowest ceiling
height installation requirements of any AHRI listed manufacturer.
Factory Quality
• All refrigerant brazing is performed in a nitrogen environment.
• Computer controlled deep vacuum and refrigerant
charging system.
• All joints are leak detected for maximum leak rate of
less than 1/4 oz. per year.
• Computer bar code equipped assembly line ensures all
components are correct.
• All units are computer run-tested with water to verify
both function and performance.
