Features/Benefits

Versatility

If room fan coils are the answer to your job requirements, choose from Carrier’s extensive range of superior fan-coil units.

With Carrier’s 42 series fan coils, you can select from 5 horizontal, 6 vertical, 5 ducted or 3 stacked models; furred-in or cabinet style, slant top or low silhouette, in 150 through 2000 cfm capacities. Coils are available with 1, 2, 3, 4, or 5 rows (depending on model), to satisfy a variety of application requirements. The units are ideal for installation in motels, apartments, and other multi-room buildings. Many optional control packages are available, including 2-pipe heating and cooling, 2-pipe heating and cooling with auxiliary electric heat, 2-pipe cooling with total electric heat, and 4-pipe heating and cooling. Also offered are manual and automatic changeover controls and several thermostat options.

Casings and frame are fabricated from tough, heavy gage galvanized steel. Optional decorative colors allow the unit to blend with any interior design.

Low-cost installation and operation

Each unit is designed to occupy a minimum space. No complex system controls are required for Carrier fan coil units. Piping, drain, and wiring connections are readily accessible and mounting holes and slots are pre-drilled to save installation time and field labor expense.

42 Series quality reduces service and maintenance expenses

Condensate drain pan is heavy gage galvanized steel with closed-cell, fire retardant foam insulation. Units come standard with Tuf-Skin™ II insulation for energy savings, sound absorption and Indoor Air Quality (IAQ) preservation. Water never touches the pan, so corrosion is minimized and long, trouble-free life is assured.

Efficient operation

All units use permanent split capacitor motors for minimum electrical consumption. Blower wheels are centrifugal-type, forward curved, double width, and double inlet sized for maximum efficiency.

Quiet, dependable performance

All units are built to operate unobtrusively with quiet motors and fans. In ad-

dition,

/2-in. thick sound-absorbing, multi-density, matt faced, neoprenecoated fiberglass insulation is used to line the cabinet.

42C series horizontal, 42V series vertical units

Carrier room fan-coil units operate at exceptionally low sound levels. A generous amount of insulation absorbs operating sound and rugged, rigid construction ensures vibration free operation at all fan speeds.

Economical, three-speed fans deliver just the right amount of conditioned air for your comfort needs at any load, and each unit can be shut off when not in use. Permanent split capacitor motors deliver peak operating efficiency. By choosing Carrier units, you can match your application with a wide range of custom-designed options and accessories, including electric heat. Filters are cleanable or throwaway type.

Motor bearings are heavy-duty sleeve type, with oversize oil reservoirs to assure long bearing life. All coils are factory leak-tested at 350 psig minimum air pressure.

Carrier room fan-coil units provide unsurpassed year-round comfort, with heating and cooling performance certified in compliance with ARI (Air Conditioning & Refrigeration Institute) 440-98.

42D ducted units

A drip lip (removable drain pan extension) is provided for field installation on ceiling models 42DA,DC,DE and DF when a motorized valve package is ordered. The drip lip is also available as an accessory for use with other controls.

Motor/blower assembly can be easily removed from the unit for ease of service. Removing this assembly provides clear access to the entering air face of the coil, making coil cleaning a relatively simple matter. Removable panels make access to components and connections easy.

42S stacked units

Each Carrier stack unit comes factoryequipped with insulated supply, return, and drain risers. The design of the 42S units allow them to be set one on top of the other in a vertical column rising floor to floor up the building. Each riser has a 3-in. belled section at the top, so the riser piping can be

connected by only one sweat connection per riser. Field-installed couplings or internal pipe connections are not needed.

Each stack unit is factory pre-wired with all control, motor, and optional electric heat wiring conveniently terminating in a single, accessible junction box. Each stack unit requires only one field power connection.

Field-mounted accessories, such as the 3-speed switch/thermostat package for furred-in units, are equipped with a pre-wired quick disconnect plug for easy installation.

The riser size for the stack units can be specified to match building requirements so that cutting, sorting, and handling of the risers is not necessary. All units arrive tagged as specified by the customer for efficient delivery to the correct building location.

Units can be loaded onto delivery trucks so that they can be off-loaded in the proper installation sequence.

washers which allow air in the pipes to pass through, automatically bleeding the system, and eliminating the need to manually remove air from the system. When wet, washers swell and seal the system.

Decorative wall panels — Wall panels are available for use with fully recessed 42VA units.

Drip lips (removable drain extension) — Drip lips are frequently used when valves are added after unit installation and space limitations will not permit use of an extended drain pan. The drip lip is placed on the end of the drain pan and is pitched toward the pan to ensure proper drainage. The drip lip gives positive control of condensate from valves and controls on 42DA, DC units (available as an option on 42DE, DF units). Provided as standard on these units when factory-supplied motorized valve package is ordered. The drip lip is also installed on the 42C series ceiling fan coil units when 2-way or 3-way motorized valve packages are ordered.

Options and accessories (cont)

Return-air grilles — Stamped-type return-air grilles are standard on 42C, V, S units. Anodized aluminum hinged bar-type grilles are installed on 42CG, CK and DF (available as an option on 42DA, DC, DE, DD) units.

Risers — The 42S series units can accommodate ¾-in. (supply and return) and 1-in. (drain) to 2½-in. riser sizes in 2-pipe systems. For other applications, such as reverse return risers or 4-pipe systems, it may be necessary to accommodate the additional risers.

Condensate drains are available in sizes down to 1-in. for greater cost economy. Riser size-reducers are factoryinstalled and for risers of over 115-in. length, filler pieces can be furnished for field installation.

Riser expansion — When necessary, the 42S series units are provided with factory-installed expansion loops. These expansion loops provide up to 1 ½-in. of riser expansion within the standard unit construction. This means that the unit can be used on installations of up to 20 floors without any additional expansion devices.

Risers material and insulation — The 42S series unit factory-installed supply, return, and drain risers can be furnished in type M or L copper. All factory-furnished risers are insulated with flexible closed foam insulation in ½-in. or ¾-in. thickness.

Supply-air grilles — Two types of double deflection supply-air grilles are available for horizontal and vertical units; an integral steel grille painted to match the unit or a separate unpainted anodized aluminum grille. Not applicable to 42VG units.

Tell-tale drain pan — A secondary drain connection is located above the primary drain to act as a “tell-tale” in the event that the primary drain becomes obstructed. They can be applied to either the main drain pan or an extended main drain pan. This option only available on the 42C, 42V (except 42VG), and 42DA, DC, DE, DF.

Thermostats control packages — The standard thermostat control option is line voltage. Wall-mounted line voltage and 24-v thermostats are available on the 42 series fan coil units. 24-v thermostat is not available on the 42VC,VE,VG unit. Thermostat control packages options refer to page 10-12.

Trim strips — Strips are available for use with partially recessed vertical 42VA units and 42S only.

Wall boxes — Wall boxes are all aluminum with insect screen behind louvers. The wall boxes are available on all 42V series units except the 42VG units.

Four-pipe thermostat, model TH104 — With this thermostat, heating and cooling are sequenced (automatic changeover) with 6 degree separation between HEATING ON and COOLING ON. The standard temperature range is 60 to 90 F.

Two-pipe thermostat, model TF103 — Single-pole double-throw (SPDT) thermostat has snap action contacts. The standard temperature range is 60 to 90 F.

Automatic changeover (Summer-Winter switch) —

The automatic-changeover thermostat is a single-pole double-throw (SPDT) thermal switch in a moistureproof and dust-proof enclosure. Thermostat mechanism and lead ends are hermetically sealed in a polypropylene enclosure with epoxy resin. Device clamps on coil supply pipe with end snap-on clip.

The set point temperatures are factory set. When water temperature rises above 80 F (approximately), the thermostat switches to the winter cycle. When water temperature drops below approximately 70 F, the thermostat switches to the summer cycle. Switch reset is automatic.

Fan coil control relay board — The fan coil relay board is used in conjunction with the Debonair thermostat or a CCN fan coil controller to regulate a single-speed or multispeed fan. The fan coil relay board can also be used to connect the fan coil controller to a line voltage valve actuator.

The fan coil relay board is factory shipped as a PC board

with four

/2-in. stand-offs attached for field mounting.

NOTE: One fan coil relay board is used for each application. Fan coils with two or more fan motors use a fan coil relay board for each fan motor. A maximum of three fan coil relay boards can be wired to one fan coil control.

Unit hand — When facing the supply air outlet from the

front of the unit (air blowing in your face), your right hand will be the right hand side of the unit and your left hand the left hand side of the unit.

UNIT HAND

Same end connection (2 pipe or 4 pipe) — All piping

connections are on the same end (side) of the unit. Controls and electrical connection will be on the end (side) opposite the piping connection.

Standard 2-pipe units will be the same end connection.

Opposite end connection (4-pipe option) — Hot water (HW) piping connections and electrical will be on the end (side) opposite the chilled water (CW) and drain connections.

OPPOSITE END CONNECTION

System piping

The following diagrams show some common methods used to pipe the 42S series units. Only the 2-pipe systems are shown; however, the methods would be the same for 4-pipe systems.

System 1, the “direct return” system, is the most common. It is economical to install since it supplies and returns the water for a riser column from the same location, at the top or the bottom of a building. This type of riser arrangement does require more attention to individual unit water flow balancing. The risers are normally capped at the end as shown in the diagrams.

System 2, the “reverse return” system, is used to minimize the requirement for individual unit balancing. This system is usually referred to as the self-balancing system. The arrangement of the risers allows the water flow for each unit in a column to be equalized. In the reverse return system both the supply and return mains are located at the top or the bottom of a building requiring an additional return riser to be furnished in the units.

System 3, the “common reverse return” system, typically has the supply and return mains located remotely from each other — such as one at the top and one at the bottom of a building. This eliminates the need for a reverse return riser in the units.

SYSTEM 2 — REVERSE RETURN

SYSTEM 3 — COMMON REVERSE RETURN

Risers

Riser diameter is an important consideration in the design of stack series systems. Standard units can accommodate

/4-in. to 21/2-in. riser sizes in 2-pipe systems. For other applications, such as reverse return risers or 4-pipe systems, it may be necessary to accommodate the additional risers.

Riser size is based on the water flow needed for a given tier of units. Unit risers are sized according to the diameter and length requirements as specified by the customer. To determine riser size, water velocity should be limited to 5 to 8 ft/second. Thus, if 10 units are to be stacked vertically with each unit requiring 3 gpm, the maximum flow in the risers is 30 gpm. Through 1 of 7.5 ft/second. The maximum flow rate of 30 gpm occurs only at the supply and return points. As the water moves upward, the flow in the supply riser is reduced by 3 gpm per floor, so that after 3 floors, the total flow is 21 gpm and riser size can be reduced to one inch. See chart on page 103.

/4 in. risers, this is a velocity

Condensate drains are available in sizes down to one

inch for greater first cost economy.

Riser size-reducers are factory installed and caps are pro-

vided at customer request.

For risers of over 115 in. length, filler pieces can be fur-

nished for field installation.

Typical arrangements

Typical arrangement applications for each model type are shown below. The fan coil units feature almost an unlimited number of arrangements to meet the needs of new construction, renovation, or reconstruction. Consult the factory for the arrangement (standard or special) to meet your particular need.

There are limitations on physical size of pneumatic valves, quantity and type of matching components, and required control interface. See Symbols and Placement of Valves diagram.

Consult factory before ordering any special valve pack-

age components that are not covered in this book.

SYMBOLS AND PLACEMENT OF VALVES

Valve packages are shipped with the units or in unit cartons. Valve packages include belled ends for field soldering to coil connections.

All factory-furnished cooling valve packages are arranged to position as much of the package as possible over an auxiliary drain pan or drip lip. This helps minimize field piping insulation requirements.

Coil Connections (Positions A & B) — When isolation valve only is added to supply or return line, the isolation valve will be factory brazed to the coil stub-out. Addition of any other component or connection to the supply or return line will change the respective coil connection(s).

Service Fittings (Positions C & D) — Optional fittings for attaching pressure/temperature sensing devices to obtain pressure drop or temperature differential across coil. Used with ball valve or balance valve where extremely accurate water flow balancing is required.

Water Flow Balancing (Positions E, F, & H) — Only one device per total valve package to be used for balancing water flow through the coil. When isolation valve (ball valve or ball valve with memory stop at position H) is used for water flow balancing, do not specify additional balancing device at position E or F. When balancing device is specified at position E or F, isolation valve does not require balancing feature at position H (with a 3-way motorized valve, a bypass balancing valve may be specified in the bypass line to permit equal flow balancing).

Strainer (Position G) — Does not include blow down fitting and should not be used in lieu of main piping strainers. Isolation Valves (Positions H & J) — Normally requires one each on supply and return line (see exception under circuit setter). When

position H is used for balancing (ball valve or ball valve with memory stop), check specifications for service valve requirements.

Electric heat

Electric heaters are available for installation on Carrier fan coil units in the following applications.

Total electric heat — This system provides complete heating during the heating season; no boiler is required. Heating and cooling are now available on an individual basis throughout the year with a 2-pipe system.

Chilled water is used for cooling and the electric heater is used for heating. Individual room controls can be supplied for either manual or automatic changeover.

Auxiliary electric heat — This system is used for heating between seasons or during the cooling season when chilled water is being circulated. Individual room controls are supplied to provide electric heat only when chilled water is being circulated through the system. Water flow through the unit is shut off when the heater is turned on.

During the winter heating season, heating is provided by hot water circulated through the system. A changeover device locks out the electric heat when the hot water is circulated.

Heater construction

Strip heaters are used with Model 42C ceiling units,

Model 42D ducted units and Model 42S stack units.

These heaters consist of coils of the highest grade resistance wire, insulated by ceramic insulators in aluminized brackets.

All heaters except those used in 42S stack units are positioned on the incoming (preheat) side of the unit coil. On

42S stack units, the strip heater is located in the fan discharge on the leaving side of the coil.

Sheath heaters are used with Model 42V vertical units. These heaters consist of the highest grade resistance wire, centered in a The wire is insulated from the sheath by magnesium oxide powder packed around it. To increase the heater surface exposed to air, a 1 wound around the sheath in a continuous spiral that makes 5 turns per lineal inch. Sheath and fin are permanently bonded together by copper brazing.

The heaters are positioned on the leaving (reheat) side of the unit coil. On special units with high efficiency motors, a strip heater will be installed in the fan discharge on the incoming (preheat) side of the unit coil.

= 15.2 x 0.98 x 1.00 = 14.9 MBtuh

8. Calculate water pressure drop. From the Cv Factor by Coil and Unit Size table on page 86, find the Cv value for unit size 06 with four rows.

Cv = 4.00 ∆P = [GPM/(0.658 x Cv)

= [10.0/(0.658 x 4.00)

= 14.4 feet of H2O

LEGEND FLA — Full Load Amps NOTES:

1. All heaters are single-stage and single-phase.

2. In all units using over 48 amps, the heating elements are sub-

divided and protected. Additional cost is incurred because of added components.

3. A separate power source is required for motor and heaters except

when motors and heaters of same voltage are ordered in conjunction with a single power source wiring option. This option, which meets NEC requirements, consists of a factory-furnished and installed junction box and fuse for 6.25 amp (max) fan and control circuit connection to a single power source. Power supply circuit to unit must be field furnished and installed in accordance with applicable codes.
