1 Product Data Air Conditioning Fan Coil Sizes thru The Model Fan-Coil Unit is designed for light commercial applications, such as small stores, restaurants and office installations. AVAILABLE OPTIONS Designed for easy installation and service, the horizontal configuration is both accommodating and efficient. The unit can be installed above or below ceilings since overall height is only 18 or 22 in. depending on model choice. Spotwelded nuts at cabinet corners provide easy suspension from 3/8-16 NCV rods. Belt-driven blowers can be adjusted to match air delivery requirements precisely to building needs. This unit lends itself to quiet air delivery with multi-room service. Forward curve blower wheels are factory balanced and have factory-lubricated ball bearings. This unit is fully insulated with R-3, 3/4-in. fiberglass. The is overload protected with a PSC-type motor for quiet, economical operation. A 2-in. filter is a standard feature. FIELD-INSTALLED ACCESSORIES 2-row hot water heating coil offers year-round duty through interface with central boiler system Expansion valve kit available through Service Parts 4-way adjustable plenum NOTE: Field-supplied blower controls required. RCD Transformer/Relay Kit is P Copyright 2001 Carrier Corporation Form -5PD

Sensible Heat Capacity (1000 Btuh) BF Bypass Factor NOTES: 1. Net capacities shown include a deduction for evaporator fan motor heat. 2. Contact manufacturer for cooling capacities at conditions other than shown in table. 3. Formulas: sensible heat cap. Leaving db = entering db 1.09 x CFM Leaving wb = wb corresponding to enthalpy of air leaving coil (h wb ) total capacity (Btuh) h wb = h ewb 4.5 x CFM where h ewb = enthalpy of air entering coil. 4. Direct interpolation is permissible. Do not extrapolate. 5. SHC is based on 80 dg temperature of air entering coil. Below 80 subtract (correction factor x CFM) from SHC. Above 80 db, add (correction factor x CFM) to SHC. BYPASS FACTOR SHC CORRECTION FACTOR ENTERING AIR DRY-BULB TEMPERATURE () Under Over 85 Correction Factor Interpolation is permissible. Correction Factor = 1.09 x (1 BF) x (db 80) Use formula shown below 7
