For the best air distribution, the unit should be centered against the longest wall, distributing the cold air as close
to heat load as possible, unless the unit is ducted. The unit should not be placed near any corner of the room or at
the end of a long, narrow room. Multiple units should be evenly spaced, as far apart as possible.
NOTICE
Condensation formation and frequent humidifier flushing are
normal functions of this equipment. Proper drain connections must be
made to ensure proper removal. Unit will require water connections for
condensate removal and possibly for humidifier makeup water, chilled
water and/or hot water. Installation of units above equipment that
could sustain water damage should be avoided.

Upflow Units
All floor mounted gPods have an upflow configuration. Upflow units will typically be supported by vibration isolation
pads and/or floor stands which may also include leveling screws. An air discharge plenum may be factory provided
which ships loose and must be attached at the top of the unit frame.
Alternately, an air distribution plenum must be field fabricated with supply grilles to distribute the air. Units are
shipped with Electronically Commutated (EC
) motors and “plug fans”. Fan speed is factory set based on order. Fan
speed can be changed in 1% increments through the unit’s microprocessor controller, Data Alarm Processor 4
(dap4). Other fan speed control options are available, and some require optional hardware to facilitate the optional
control. See the dap4 operation manual for details and recommended settings.
Locating Ceiling Units
The unit is intended for above the ceiling installation and is typically suspended from structural members in the
building above the ceiling. The Design Engineer must determine the necessary strength of the supporting structures
and follow national and local building codes.
Appropriate service access above the ceiling is required around all service and electrical access panels. There must
be unobstructed clearance below the unit allowing ladder access to enable routine maintenance and service.
Consult local building codes and National Electric Code for special installation requirements.
NOTICE
There are many available unit configurations for ceiling mounted
gPods. Be sure to identify the unit type and style before installing. For
instance, there may be split condenser sections requiring separate or
shared power.
NOTICE
Condensation formation and frequent humidifier flushing (when
humidifier is installed) are normal functions of this equipment. Drain
connections must be made to ensure proper water removal. Unit will
require drain connections for condensate removal and wat er
connections possibly for humidifier (when installed) makeup water,
condenser water, chilled water and/or hot water. Installation of units
above equipment that could sustain water damage should be avoided.
