SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extinguishers available for all brazing operations.

Recognize safety information. This is the safety--alert symbol

. When you see this symbol on the furnace and in instructions or manuals, be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, and CAUTION. These words are used with the safety--alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies a hazard which could result in personal injury or death. CAUTION is used to identify unsafe practices which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could cause personal injury or death.

Before performing service or maintenance operations on unit, turn off main power switch to unit and install lockout tag. Ensure electrical service to rooftop unit agrees with voltage and amperage listed on the unit rating plate.

WARNING

FIRE, EXPLOSION HAZARD

Failure to follow this warning could death and/or property damage.

Disc onnect gas piping from unit when leak testing at pressure greater than psig will cause gas valve damage resulting in hazardous condition. If gas va lve is subjecte d to pressure greater than

/2psig, it must be replaced before use. When pressure testing field-supplied gas piping at pressures of less, a uni t connected to such piping must be i solated by manual l y closing the gas valve(s).

WARNING

INSTALLATION

Unit is shipped in the vertical discharge configuration. To convert to horizontal discharge application, remove duct opening covers. Using the same screws, install covers on duct openings in

48HE,HJ

basepan of unit with insulation-side down. Seals around openings must be tight. (See Fig. 1.)

Fig. 1 --- Horizontal Conversion Panels

Step 1 —Provide Unit Support

CURB

ROOF

Assemble and install accessory roof curb in accordance with instructions shipped with curb. (See Fig. 2.) Install insulation, cant strips, roofing felt, and counter flashing as shown. Ductwork must be attached to curb, not to the unit. If electric control power or gas service is to be routed through the basepan, attach the accessory thru-the-bottom service connections to the basepan in accordance with the accessory installation instructions. Connections must be installed before unit is set on roof curb.

IMPORTANT: The gasketing of the unit t o the roof curb is critical for a watertight seal. Install gasket supplied with the roof curb as shown in Fig. 2. Improperl y applied gasket can result in air leaks and poor unit performanc e.

Curb should be level. Unit leveling tolerances are shown in Fig.

3. This is necessary for unit drain to function properly. Refer to Accessory Roof Curb Installation Instructions for additional information as required.

SLAB MOUNT (Horizontal Units Only)

Provide a level concrete slab that extends a minimum of 6 in. beyond unit cabinet. Install a gravel apron in front of

C06108

condenser-coil air inlet to prevent grass and foliage from obstructing airflow.

NOTE: Horizontal units may be installed on a roof curb if required.

ALTERNATE UNIT SUPPORT

When the curb or adapter cannot be used, support unit with sleeper rails using unit curb or adapter support area. If sleeper rails cannot be used, support the long sides of the unit with a minimum of 3 equally spaced 4-in. x 4-in. pads on each side.

Step 2 —Field Fabricate Ductwork

Secure all ducts to roof curb and building structure on vertical discharge units. Do not connect ductwork to unit. For horizontal applications, field-supplied isolation flanges should be attached to horizontal discharge openings and all ductwork should be secured to the flanges. Insulate and weatherproof all external ductwork, joints, and roof openings with counter flashing and mastic in accordance with applicable codes.

Ducts passing through an unconditioned space must be insulated and covered with a vapor barrier.

If a plenum return is used on a vertical unit, the return should be ducted through the roof deck to comply with applicable fire codes.

A minimum clearance is not required around ductwork. Cabinet return-air static pressure (a negative condition) shall not exceed

0.35 in. wg with economizer or 0.45 in. wg without economizer. These units are designed for a minimum continuous return-air

temperature in heating of 50_F (dry bulb), or an intermittent operation down to 45_F (dry bulb), such as when used with a night setback thermostat.

To operate at lower return-air temperatures, a field-supplied outdoor air temperature control must be used to initiate both stages of heat when the temperature is below 45_F. Indoor comfort may be compromised when these lower air temperatures are used with insufficient heating temperature rise.

Step 3 —Install External Trap for Condensate Drain

The unit’s bottom and side of the unit. Unit discharge connections do not determine the use of drain connections; either drain connection can be used with vertical or horizontal applications.

When using the standard side drain connection, ensure the plug (Red) in the alternate bottom connection is tight before installing the unit.

To use the bottom drain connection for a roof curb installation, relocate the factory-installed plug (Red) from the bottom connection to the side connection. The center drain plug looks like a star connection, however it can be removed with a socket drive extension. (See Fig. 4.) The piping for the condensate drain and external trap can be completed after the unit is in place.

All units must have an external trap for condensate drainage. Install a trap 4-in. deep and protect against freeze-up. If drain line is installed downstream from the external trap, pitch the line away from the unit at 1 in. per 10 ft of run. Do not use a pipe size smaller than the unit connection (

Step 4 —Rig a nd Place Unit

Inspect unit for transportation damage, and file any claim with transportation agency. Keep unit upright and do not drop. Spreader bars are not required if top crating is left on unit, and rollers may be used to move unit across a roof. Level by using unit frame as a reference. See Table 1 and 2 and Fig. 6 for additional information. Operating weight is shown in Table 1 and 2 and Fig. 6.

To install the humidistat:

1. Route humidistat cable through hole provided in unit control box.

2. Some models may be equipped with a raceway built into the corner post located on the left side of control box (See Fig. 15). This raceway provides the required clearance between high--voltage and low voltage wiring. For models without a raceway, ensure to provide the NEC required clearance between the high--voltage and low--voltage wiring.

3. Use a wire nut to connect humidistat cable into lowvoltage wiring as shown in Fig. 18.

To install Thermidistat device:

1. Route Thermidistat cable through hole provided in unit control box.

3. A field-supplied relay must be installed between the Thermidistat and the Humidi-Mizer circuit (recommended relay: HN612KK324). (See Fig. 19.) The relay coil is connected between the DEHUM output and C (common) of the unit. The relay controls the Humidi-MiZer solenoid valve and must be wired between the Humidi-MiZer fuse and the low-pressure switch. Refer to the installation instructions included with the Carrier Light Commercial Thermidistat device for more information.

premierlink

 control

The PremierLink controller is compatible with Carrier Comfort NetworkR (CCN) devices. This control is designed to allow users the access and ability to change factory--defined settings, thus expanding the function of the standard unit control board. Carrier’s diagnostic standard tier display tools such as Navigatort or Scrolling Marquee can be used with the PremierLink controller.

The PremierLink controller (see Fig. 24 and 25) requires the use of a Carrier electronic thermostat or a CCN connection for time broadcast to initiate its internal timeclock. This is necessary for broadcast of time of day functions (occupied/unoccupied). No sensors are supplied with the field-- mounted PremierLink control. The factory--installed PremierLink control includes only the supply-- air temperature (SAT) sensor and the outdoor air temperature (OAT) sensor as standard. An indoor air quality (CO2) sensor can be added as an option. Refer to Table 5 for sensor usage. Refer to Fig. 26 for PremierLink controller wiring. The PremierLink control may be mounted in the control panel or an area below the control panel.

NOTE: PremierLink controller versions 1.3 and later are shipped in Sensor mode. If used with a thermostat, the PremierLink controller must be configured to Thermostat mode.

Install the Supply Air Temperature (SAT) Sensor

When the unit is supplied with a factory--mounted PremierLink control, the supply--air temperature (SAT) sensor (33ZCSENSAT) is factory-- supplied and wired. The wiring is routed from the PremierLink control over the control box, through a grommet, into the fan section, down along the back side of the fan, and along the fan deck over to the supply--air opening.

The SAT probe is wire--tied to the supply--air opening (on the horizontal opening end) in its shipping position. Remove the sensor for installation. Re-- position the sensor in the flange of the supply-- air opening or in the supply air duct (as required by local codes). Drill or punch a 1/2--in. hole in the flange or duct. Use two field--supplied, self--drilling screws to secure the sensor probe in a horizontal orientation.

NOTE: The sensor must be mounted in the discharge airstream downstream of the cooling coil and any heating devices. Be sure the probe tip does not come in contact with any of the unit or heat surfaces.

Outdoor Air Temperature Sensor (OAT)

When the unit is supplied with a factory-mounted PremierLink control and economizer, the outdoor-air temperature sensor (OAT) is factory-supplied and wired.

Install the Indoor Air Quality (CO

Mount the optional indoor air quality (CO

)Sensor

) sensor according to

manufacturer specifications. A separate field-supplied transformer must be used to power the

sensor.

Wire the CO

sensor to the COM and IAQI terminals of J5 on the

PremierLink controller. Refer to the PremierLink Installation, Start-up, and Configuration Instructions for detailed wiring and configuration information.

Enthalpy Sensors and Control

The enthalpy control (HH57AC077) is supplied as a field-installed accessory to be used with the EconoMi$er2 damper control option. The outdoor air enthalpy sensor is part of the enthalpy control. The separate field-installed accessory return air enthalpy sensor (HH57AC078) is required for differential enthalpy control.

NOTE: The enthalpy control must be set to the “D” setting for differential enthalpy control to work properly.

The enthalpy control receives the indoor and return enthalpy from the outdoor and return air enthalpy sensors and provides a dry contact switch input to the PremierLink controller. Locate the controller in place of an existing economizer controller or near the actuator. The mounting plate may not be needed if existing bracket is used.

A closed contact indicates that outside air is preferred to the return air. An open contact indicates that the economizer should remain at minimum position.

Outdoor Air Enthalphy Sensor/Enthalpy Controller (HH57AC077)

T o wire the out door air enthalpy sensor, perform the following (See Fig. 27 and 28):

NOTE: The outdoor air sensor can be removed from the back of the enthalpy controller and mounted remotely.
