34 APC NetworkAIR CM Series: Guide Specifications

Smoke detector. A smoke detector shall ship loose for field installation into

ductwork. Upon smoke, the unit shall shut-down. If equipped with a

microprocessor, an audible and visual alarm shall be activated at the

microprocessor display/keypad.

Condensate pump. A condensate pump with a capacity of 36 GPH (37.8

mL/s) at 15 ft. (45 kPa) of head shall ship loose for field attachment to the

side of the unit. The condensate pump shall be complete with a 1.7qt. (1.6L)

reservoir, float switch, and pump/motor assembly.

Pre-cooling coil. The environmental control system shall be equipped with

a Pre-Cooling coil constructed of copper tubes/aluminum fins to serve as an

alternate source of cooling. pre-cooling shall be available when a pre-set

glycol temperature is available. If not available, the traditional DX cooling

mode will prevail. The pre-cooling coil shall have a total cooling capacity of

_____ MBH (_______ kW) and a sensible cooling capacity of _____ MBH

(_______ kW) based on an entering glycol temperature of _____° F (_____°

C) and leaving glycol temperature of _____° F (_____° C). The Pre-Cooling

coil shall require a flow rate of _______ GPM (_______ L/s) with a

maximum system pressure drop of _______ PSI (_______ kPa). The Pre-

cooling coil and water/glycol cooled condenser shall utilize the same inlet/

outlet connections.

ECWS cooling coil. The environmental control system shall be equipped

with an ECWS (External Chilled Water Supply) cooling coil constructed of

copper tubes/aluminum fins to serve as an alternate source of cooling. ECWS

cooling shall be available after verification of water flow and acceptable

water temperature. If not available, the traditional DX cooling mode will

prevail. The ECWS coil shall have a total cooling capacity of _______ MBH

(_______ kW) and a sensible cooling capacity of _______ MBH (_____ kW)

based on an entering water temperature of _______° F (_______° C) and

leaving glycol temperature of _______° F (_______° C). The ECWS coil

shall require a flow rate of _______ GPM (_______ L/s) with a maximum

system pressure drop of _______ PSI (_______ kPa). The ECWS coil and

water/glycol cooled condenser shall require separate inlet/outlet connections.
