IMPORTANT: This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with these instructions may cause radio interference. It has been tested and found to com- ply with the limits of a Class A computing device as de®ned by FCC regulations, Subpart J of Part 15, which are designed to provide reasonable protection against such interference when operated in a commercial environment.

SAFETY CONSIDERATIONS

Installation and start-up of air-conditioning equipment can be hazardous due to system pressure and electrical compo- nents. Only trained and quali®ed service personnel should install, start up, or service air-conditioning equipment.

When working on air-conditioning equipment, observe pre- cautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply.

Follow all safety codes, including ANSI (American National Standards Institute) Z223.1 (latest version). Wear safety glasses and work gloves.

Disconnect all power to the unit before performing main- tenance or service. Unit may automatically start if power is not disconnected. Electrical shock and personal in- jury could result.

Do not store or use gasoline or other ¯ammable vapors and liquids in the vicinity of this or any other appliance.

GENERAL

The Product Integrated Control (PIC) option is available for 39L and 39NX indoor units with a draw-thru con®gu- ration. The PIC control box can be supplied as part of a dedi- cated PIC section; it is factory-installed and wired and has the same hand (orientation) as the fan section. The control box can also be shipped separately for remote mounting with- out a PIC section. For the remote control box option, all con- nections from the control box to the unit are made to a junc- tion box in the unit's fan section.

The control box includes electronic modules, fuses, re- lays, transformers, terminal blocks, low-limit air tempera- ture protection (optional), static pressure transducer (VAV

[Variable Air Volume] units only) and high-pressure switch (VAV units). An ON/OFF switch is included to shut off the power to the control box.

PIC environmental limitations are as follows:

Shipping Temperature

Ð −20 to 165 F

Shipping Humidity

Ð 10 to 95%

Operating Temperature Ð 32 to 125 F

Operating Humidity Ð 30 to 90%

INSTALLATION

Follow all basic installation instructions for 39L or 39NX units as described in the 39L or 39NX Installation, Start-Up, and Service Instructions shipped with the unit. To verify the PIC and PIC option con®gurations according to the model numbers, see Fig. 1 and 2.

Leave protective coverings on the unit until it is installed inside and protected from the elements, construction debris, and dirt.

Use one of the keys provided in the 39L or 39NX instal- lation packet (located in fan section) to open the control box door. Visually inspect all components and wiring for any dam- age. Remove the valve assembly packages and the sensor packages from the fan section. For units with PIC sections, remove protective plastic caps from the bulkhead ®ttings (located on the top edge of the control box) and discard.

Verify that the 10.0 amp ON/OFF switch located on the PIC control box door is in the OFF position. Do not turn the power supply on at this time.

NOTE: The 39NX and 39L air handlers are designed for in- door applications. Modi®ed units are available for outdoor applications on pier or slab mounts (not curb mounts). Prod- uct integrated controls are not available for outdoor appli- cations. Consult your Carrier sales representative for further details.

Service Area Requirements Ð Article 110-16 of the NEC (National Electrical Code) describes electrical instal- lation. All 39L and 39NX PIC installations must comply with the minimum clearances required for electrical installation as listed in Table 110-16(a) of the code. Make sure to pro- vide the necessary clearance from the PIC unit to any ad- joining wall. Refer to the base unit installation instructions for detailed dimensions for each unit section.

Remote Control Box Option Ð This option allows the PIC control box to be mounted away from the unit; the remote control box (Fig. 3) must be wired to the supply fan section. Mount the remote control box assembly to the mechanical room wall near the unit using ®eld-supplied Unistrut metal framing or equivalent supports. The control box has 4 mounting holes in the back of the enclosure for this purpose.
