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. Location of electrical outlet. Place the equipment no farther than 2.4 m (8 ft) from a dedicated 115V, 60Hz, 20A branch circuit receptacle.
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 na0418a Condenser air intake duct Assemble the ceiling adapter Caution: The air deflector must face away from the air intake and obstructions such as walls or piping.
Install the adapter in a drop ceiling Use the ceiling adapter to provide an intake and exhaust outlet for the condenser. Note: Allow at least 305 mm (12 in) of open space above the ceiling adapter opening so exhaust air is not blocked. 1. Determine a location to install the ceiling adapter. 2. Remove the ceiling tile in the chosen location and save it for a future step. na0373a 3. Place the ceiling adapter into the ceiling tile grid. na0397a 4.
Assemble the ducts 1. Thread the duct collars counterclockwise onto each of the ducts until they bottom out. na0312a Note: The hoses used are directional and reduce airflow if not properly installed. Expand the length of hose to fit the required space. 2. Install each hose so that the leading edge of the compressed section of the hose matches air direction flow. na1235a Air Flow 3. Slide the duct collar of each hose over the ceiling adapter sleeves and turn the duct collar to lock in place.
Drain Line The equipment contains an on-board condensate pump for automatic condensate removal.The equipment ships with 15.24 m (50 ft) of hose and a quick-connect fitting for removing condensate. You can attach a different hose to the equipment if you follow these requirements: • You must use a 6-mm (1/4-in) outside diameter (OD), clear, polyurethane hose. • The hose length must not exceed 15.24 m (50 ft), and 4.88 m (16 ft) vertical maximum.
Accessories Temperature/humidity sensor The Remote Temperature/humidity sensor (AP9512TH) monitors the room temperature and relative humidity. This remote sensor monitors the environment surrounding the cooling equipment to ensure that the conditioned air is cooling the desired area. Note: The equipment cannot be controlled based on the temperature measured by the sensor. To install the sensor: 1. Determine a location that allows you to neatly route and secure the 3.
Relays and Contacts Overview The controller board provides connectors for output relays and input contacts. The connectors can be used with any dry-contact sensors. The connectors are designed to monitor circuits that have no voltage potential of their own. Connecting the contact or relay to any circuit other than a dry closure connector may result in damage to the main control board.
To connect an output relay: 1. Attach a 12-position terminal block (provided) to the output relay connector. 2. Strip the wire insulation on the sensor 6 mm (0.25 in) from the end. 3. Connect your sensor wires to the pins associated with one of the four positions on the output relay connector. 4. Configure the settings for the output relay through the display interface. See “Set Up Contacts and Relays” on page 26.
Start-Up Start-up checklist Before starting the equipment, check to see that the following conditions are met: • All electrical connections comply with national and local codes and safety standards. • All accessories and ductwork have been installed. • Air flow to and from the equipment is not blocked. • The condensate drain is connected and not kinked or pinched. How to apply power to the equipment Insert the IEC-320-C19 connector of the power cord into the back of the equipment.

Alarm messages Alarm Message Action Required High head pressure Ensure condenser exhaust air diverter is not blocked, facing a wall, or pointed at the condenser air inlet. Check the area above the ceiling where the condenser air is circulating for excessive heat buildup. Additional ventilation may be required. Check the condenser inlet filter for cleanliness. Supply temperature high Alarm setpoint may be too low. Alarm should normally be set to 10° (C or F) above the cool setpoint plus the dead band.
Alarm Message Action Required Remote temperature high Alarm setpoint may be too low. Check the sensor placement. Ensure that the sensor is able to sense the cool supply air from the unit. Check that the sensor is not near a direct heat source such as an equipment discharge fan, a room supply duct, a window, direct sunlight, or a room entrance. Equipment capacity may be too small for room load. Check that the equipment is cooling.

Maintenance and Troubleshooting Maintenance Replace the air filter Replace the air filter every 90 days or sooner if an alarm occurs. Keep the air filter clean to maximize the performance and life of the equipment. Note: For maximum efficiency and to prevent equipment damage, always replace the filter with the size and type given below. 1. Slide the filter element out from the rear of the equipment. na0153a 2. Insert a new air filter (APC part number ACPA4000RF).
Clean the condenser filter and test the LCDI plug The condenser filter traps large items that may fall into the ducts. Periodically check and clean the filter to prevent damage to the condenser. While power is off, test the LCDI plug for proper operation. 1. Turn off the equipment and unplug it from its electrical outlet. 2. Remove the condenser air intake duct from the back of the equipment. 3. Clean the filter (inside the air intake duct) using your hand or a dry cloth.
Troubleshooting Problem Possible cause Corrective action Equipment does not respond Main power is off. Check building fuse or circuit breaker. Equipment is not plugged in. Securely insert the plug into the outlet. LCDI power cord has tripped. If the green LED on the back of the LCDI plug is not on, press the RESET button on the plug. If the LED does not light, replace the power cord. Equipment circuit breaker has tripped.
