990-4617 InRow™ Direct Expansion Air Conditioners Technical Specifications 7
Condensate pump
ACRD100 and ACRD200 series:
A condensate pump is factory wired and piped internally to the condensate drain pan. The pump is capable of
pumping 34 l/h (9 g/hr) against head pressures of up to 50 ft (15.2 m) of total run. Of that run, 16 ft (4.9 m) can
be vertical lift as measured from floor level. Dual floats are included with the unit. One float is used for
condensate pump control, and the other float generates a condensate pump failure alarm. The InRow DX can
be set to either continue running in an alarm condition or shut down to prevent condensate pan overflow.
ACRD500 and ACRP100 series:
A condensate pump is factory wired and piped internally to the condensate drain pan. The pump is capable of
pumping a maximum of 18 m (60 ft) at 32 l/h (8.45 g/hr), which may include a maximum lift of 3.5 m (11.5 ft)
as measured from floor level. Within the condensate pump, there is a dual position float. The first position is
used for condensate pump control and the other float generates a condensate pump failure alarm to prevent
condensate pan overflow.
Remote temperature sensors
To control the unit based on rack inlet temperature, remote temperature sensors are provided. The ACRD100
and ACRD200 series units come equipped with one temperature sensor, and the ACRD500 and ACRP100
series units come equipped with three. These sensors measure temperature at a point 4 m (13 ft) from the
connection inside the InRow DX unit. These sensors are used for remote placement in the field on an adjacent
IT rack.
Electric reheat (ACRP100 series only)
Electric reheat elements are low watt density, wired for three-phase and loaded equally on all three phases, and
electrically and thermally protected by both automatic and manual reset thermal cut outs. Reheat elements are
stainless steel, fin tubular construction.
Pipe adapters (ACRD500 and ACRP100 series only)
Standard pipe connections are 31.75 mm (1 1/4 in) 12 UNF female threaded ring seal (manufactured in
accordance with ANSI B1.1). The adapter converts the threaded ring seal to a sweat adapter.
Humidifier (ACRP100 series only)
The humidifier is a self-contained, steam-generating type, factory piped and wired, with a disposable cylinder
and an automatic solid state control circuit. Humidifier canisters are replaceable. The humidifier controller
communicates directly to the microprocessor controller and provides complete status and control at the
operator interface.
