*
All available options (tonnage, ductwork connections, AC options etc.) are shown. Refer to the submittal
and other relevant documentation for your equipment options, dimensions etc.
** The pool water heating option relies on compressor ‐ created excess heat and is used as an additional
heating source. It does not eliminate the need for a main pool water heater.
*** For specific details on space heating (hot water, gas, electric) option, refer to the submittal and other
documentation:

Gas ‐ fired duct heater can be incorporated with the dehumidifier (installed on the top of it) for some models (NE004 to
NE007 only); this configuration limits the RA and SA options to a “loop ‐ back” arrangement. For other models, a similar
gas heater can be provided for field installation (to be fitted in the supply air ductwork).

Electric heater , depending on various factors (capacity, model, size, etc.), can be installed externally (mounted on the
top of SA opening) or internally. Refer to your dehumidifier’s submittal documentation.
Dehumidifier External Systems Connection
Pic. C.1 shows provisions for external systems connections, including ductwork, electric power and control wires
and various piping connections.

Except for the condensate, all other piping systems are optional and may not be present in each dehumidifier.

Air Conditioning (AC) Connection. Normally, the dehumidifier has only one AC option – air ‐ cooled (requiring
connection to the outdoor air condenser) or water ‐ cooled (requiring connection to the fluid cooler or other
external water ‐ cooled system such as geothermal, cooling tower, etc.). Therefore, only one of these options
present with the actual dehumidifier.

Gas line . If the dehumidifier is equipped with a gas heater (boiler, gas furnace etc.) for space heating
purposes, the gas line connection is to be brought to the gas heater directly.
NOTE.
Dehumidifier MUST be equipped with a P ‐ trap at the condensate connection for proper operation! If
dehumidifier is requested/provided from the factory without P ‐ trap, one MUST be installed on site prior to
dehumidifier being commissioned. Refer to the dehumidifier stickers and Installation Manual for details.
CAUTION!
Current manual shows general/default connections’ location. For details regarding specific
dehumidifier’s connections (actual location, piping sizes and position dimensions, circuit type and flow direction
etc.), refer to the dehumidifier’s submittal documentation as well as dehumidifier’s labels and stickers.
WARNING!
Gas Line. The gas line must be installed in accordance with respective device documentation
(boiler, furnace, etc.) and local codes and regulations.
Attention! Equipment Clearances and Dimensions!
CAUTION!
For equipment proper operation, maintenance and service, respective clearances should be
maintained. Generally, 30” clearances to the equipment must be kept for the maintenance and service purposes.
For the specific required clearances information, as well as dehumidifier overall dimensions, distances to pipe
connections, duct connections etc., refer to the submittal documentation.
Attention: R3 Module
Note:
If the dehumidifier is equipped with the R3 Module (see your equipment submittal documentation), refer
to the R3 Module chapter in this manual for additional information about module options, layout, and operation.
