APC Condenser 2 EC Fan ACCD75208 User Manual

The frame is constructed of 1.5 mm 
(16 gauge) formed steel for 
maximum strength. Cabinet is 
serviceable from the front and rear. 
All exterior panels and corner posts 
on the frame are powder coated for 
durability and an attractive finish. 
Front and rear exterior panel are 
constructed of 1.2 mm (18 gauge) 
perforated steel with 69.5% open free 
area. Insulation is 80.1 kg/m

density and complies with 

ASTM E84 rating of 25/50. All 
panels include a key latch for safety 
and security for easy access and 
removal.

The InRow RP unit is equipped with 
variable speed, electrically 
commutated, 400 mm (15.8-in) 
backward incline, direct drive fans. 
The chilled water unit is equipped 
with three fans while the air-cooled 
unit has two. In order to provide 
uniform airflow over the cooling coil, 
the fans provide a draw-through air 
pattern. Fans are easily serviced in 
the field.

The unit provides one field 
connection input for remote 
shutdown and one field connection 
alarm output.

Internal piping of the unit includes a 
flow meter wired into the 
microprocessor controller to display 
chilled water flow and determine 
operating performance.

A floating point valve is 
microprocessor controlled to regulate 
the amount of chilled water into the 
cooling coil to maintain desired 
conditions. The standard valve 
pressure rating is 4136.8 kPa 
(600 psig). The maximum operation 
pressure of the unit is 2068.4 kPa 
(300 psig). The valve is user 
configurable to be two-way or three-
way.

Designed for high sensible heat 
ratios, the coil is constructed with 
copper tubes, raised lance type 
aluminum fins, and 1.2 mm (18 
gauge) galvanized steel end plates. 
Coil headers are equipped with anti 
drip shields in case of condensation. 
Condensate pan is UL94 V-0 thermal 
formed non-ferrous material sloped 
for positive drainage for higher 
indoor air quality.

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.

The filtration of conditioned air is 
extremely vital to maintaining the 
clean, particle-free environment 
required by electrical equipment. The 
system uses a 30% efficient, 100 mm 
(4 in), deep loading, pleated filter. 
Deeper filters produce a lower 
pressure drop, requiring less energy 
during normal operation. The filter is 
moisture resistant up to a 100% 
relative humidity. Filters are easily 
replaceable from the rear of the unit.

Standard pipe connections are 
38.1 mm (1 1/2 in) NPSM 
(manufactured in accordance with 
ANSI B.1.20.1). 

Standard pipe connections are 
31.75 mm (1 1/4 in) 12 UNF female 
Rotolock (manufactured in 
accordance with ANSI B1.1). The 
adapter converts the rotolock to a 
sweat adapter.

Unit includes both top and bottom 
piping connections. Top piping 
connects to internal stubs and routes 
piping upward out of the unit. 
Bottom piping connects to internal 
stubs and routes piping downward 
out of the unit. All connections 
utilize unions or rotolok fittings for 
ease of installation and service
