General Information
Overview
About the NetworkAIR ACPA4000
Your NetworkAIR ACPA4000 is a portable, compact air conditioner designed for spot-cooling,
emergency-cooling, and after-hours cooling of server closets, data centers, conference rooms, home
offices, or rooms that house heat-sensitive equipment.
The ACPA4000 provides 3.8 kWh (13,000 BTU) of cooling power. It automatically adjusts room
temperature and reduces moisture while filtering the air. Additional features of the equipment include:
• Electronic control panel with LCD display
• On/Off scheduling
• Automatic restart after power failure
• Two condenser ducts; one for inlet and one for exhaust
• High-head pressure cut-out to prevent compressor damage
• Hot gas bypass to prevent coil freeze-up
• Remote Web monitoring
• On board condensate pump

Safety
Warning: Use the equipment on a flat surface.
Do not obstruct the equipment air outlets.
For indoor use only.
Do not attempt to service the equipment except to clean and replace the air filters. The equipment
contains no other user-serviceable parts.
Do not place the rear of the equipment closer than 203 mm (8 in) to any wall or obstacle.
Do not install the equipment where there are fumes or flammable gases, or in an extremely humid
space such as a greenhouse.
Do not place this equipment on its side. If the equipment has been tipped, place it upright on a
flat, solid surface and keep it in this position for a minimum of 12 hours before operating.
Electrical Hazard: Connect the equipment to a 3-wire AC outlet (two poles plus a ground).
The receptacle must be connected to a dedicated, properly grounded 115 volt 60Hz branch circuit
rated for 20 amp main protection (fuses/circuit breaker). Connection to any other power source
may result in a shock hazard or damage to the equipment.
Use the equipment with the supplied power cord only.
Do not use an extension cord.
Inspecting the Equipment
Your equipment has been tested and inspected for quality assurance before shipment. To ensure that the
equipment has not been damaged during transit, carefully inspect both the exterior and interior
packaging of the equipment immediately upon receipt.
Verify that all parts ordered were received as specified. See “Inventory” on page 4.
Filing a claim
If damage is identified on receipt of the equipment, note the damage on the bill of lading and file a
damage claim with the shipping company. Contact APC for information on filing a claim with the
shipping company. The shipping claim must be filed at the receiving end of the delivery.
Note: In case of shipping damage, do not operate the equipment. Keep all packaging for
inspection by the shipper and contact APC customer support at one of the numbers listed on the
back cover of this manual.
Storing the Equipment Before Installation
Caution: Leaving the equipment uncovered and exposed to the elements can cause damage
and voids the factory warranty.

Installation
Where to locate the equipment
When deciding where to locate the
equipment, consider your cooling needs, air
flow, the location of the electrical outlet (no
more than 2.4 m (8 ft) from the equipment),
and access for the condenser intake and
exhaust.
Cooling needs. Position the equipment as
close as possible to the main source of heat
that requires cooling.
Air flow. Position the equipment so that its
rear is at least 200 mm (8 in) away from a
wall or other equipment.
Location of electrical outlet. Place the
equipment no farther than 2.4 m (8 ft) from
a dedicated 115V, 60Hz, 20A branch circuit
receptacle.
na0143a
Dimensions are shown in mm (in).
Electrical Hazard: Do not use extension cords with this equipment. Using an extention
cord reduces circuit protection and voids the warranty.
Caution: To help avoid loss of cooling, only connect this equipment to a single-outlet
dedicated circuit.
Lock the rolling casters
To prevent the equipment from rolling, press down on the
locking tabs on the two front casters.

Intake and Exhaust Vents
Hose connections
The equipment requires the installation of intake and
exhaust ducts for the condenser. See the drawing to
identify the intake and exhaust sides of the equipment.
Building structural support
10-gauge (minimum) steel wire
Ceiling adapter
Air deflector
Condenser exhaust duct
Condenser air intake duct
Assemble the ceiling adapter
Attach the air deflector to the exhaust side of the ceiling adapter
using three M6 nuts.
Caution: The air deflector must face away from the
air intake and obstructions such as walls or piping.
Failure to position it in this way reduces cooling
capacity and could cause alarms.
