R3 Module Operational Options.
1. Additional Blower option: additional blower, installed in R3 Module, could serve as:
o
Main Blower Parallel Booster Fan, to increase dehumidifier’s total air flow, OR
o
Minimum Exhaust Fan.
2. Full Flow Pool Water Heater option allows for direct piping into main pool circulating loop as well as
maximum compressor heat rejection to pool water.
3. Full AC with NO Outdoor Condenser option combines the Full Flow Pool Water Heater and Minimum Exhaust
Fan with Evaporative Condenser, installed in the exhaust airstream.
R3 Module External Systems Connection.
R3 Module is integrated with the dehumidifier ‐ most external systems are connected to the module with or via
the dehumidifier, including electric power, control, ductwork and piping connections (except for pool water
connections for Full Flow Pool Water Heater option).

Air duct connections for return and discharge air are brought, respectively, to the joined module and
dehumidifier return air collars and discharge air damper (ducted per the module’s option – main booster fan
or exhaust fan).
o
No duct connections needed if the module’s only one option is Full Flow Pool Water Heater.
Full Flow Pool Water Heater connections are normally brought through the module piping connection panel. Pic.
K.1 shows front ‐ right located piping connection panel, however its location may vary (front ‐ center or side ‐ right)
depending on R3 Module size and other features. Refer to your equipment submittal and other documentation for
more details.
o
For piping connections sizes and flow direction ‐ refer to R3 Module and the dehumidifier labels and
stickers.

Condensate (drain line) is to be connected underneath the module floor (see Pic.K.1). Normally the R3 module
condensate connection comes with a P ‐ trap; if the P ‐ trap is not installed at the factory, one must be installed
on ‐ site. Refer to the Installation Manual for additional information.
R3 Module Layout and Components.
R3 Module basic layout, shown on Pic. K.2 (components, sensors, systems connections, etc.) is similar for all sizes
and models; however, there might be some variances. Refer to your equipment submittal and other documents.

Pic. K.2 and description below covers all options. Each R3 Module has the requested options only and may not
have all options shown below – refer to submittal documentation for details.

The fan (booster or exhaust) and full flow pool heater options could be installed together or separately
(independently from each other), while Full AC with NO Outdoor Condenser option requires an exhaust fan
AND full flow pool heater for proper operation of the dehumidifier overall.
CAUTION!
Current manual shows general/default connections’ location. For details regarding specific
dehumidifier and R3 Module connections (actual location, piping sizes and position dimensions, circuit type and
flow direction etc.), refer to the equipment submittal documentation as well as equipment labels and stickers.
