STANDARD SPECIFICATIONS

A. GeneralThese Air Handling Units are factory fabricated and assembled, consisting of forward-curved fan section with blower

motor, chilled/hot water coil, electric heaters (optional), filters & electrical control box and are suitable for indoor applica-

tions. The unit is ready to operate when connected to piping, power/controls and air ducts or plenums.

They should be ordered separately as horizontal air discharge or vertical air discharge units as per application require-

ments.

B. Unit EnclosureCasing Panels are of heavy gauge (G-90) galvanized steel. Removable access panels are provided for inspection and

access to all internal parts. These panels are insulated with 1/2" thick fiberglass insulation to prevent condensation from

forming on the unit casing. Insulation meets the requirements of NFPA 90A and is protected against deterioration and

errosion from air currents. Steel sheet is zinc-coated, galvanized by the hot dip process of lock forming quality conform-

ing to ASTM A 653 commercial weight G-90, followed by baked-on electrostatic polyester dry powder coat.

C. CoilsCoils are of the enhanced louvered fin-and-tube type, constructed of seamless copper tubes, mechanically bonded to

aluminum fins. As an option, corrugated copper or enhanced coated aluminum fins may be provided.

The standard chilled water coil is 3 row for BWY03, BWY05 & BWY07 and 4 row for BWY10 & above. For heating

application, the coils are split as 2 row chilled water + 1 row hot water for BWY03, BWY05 & BWY07 and 3 row chilled

water + 1 row hot water for BWY10 & above. End plates and tube support sheets are 18 gauge galvanized steel, formed

to provide structural strength.

Each coil is pressure tested in the factory at not less than 300 psi (2070 kPa) air pressure. Coils conform to ARI 410.

D. Drain PansDrain pans provided under cooling coil section are made of G-90 galvanized steel with mastic coated liner for additional

corrosion protection and the outer surface is thermally insulated. Drain outlets of 3/4" NPT is provided for field connec-

tion.

E. Evaporator FanEvaporator fan is of a centrifugal forward-curved blade design and sized to meet system airflow/pressure. Fan motor

(except for BWY03 & BWY05, which have direct drive motors) is mounted on an adjustable base and secured by a

locking device. Fan drive is through adjustable motor pitch pulley and belt-driven. Fan shafts are designed to operate at

less than 2/3rds of the first critical speed when the unit comes up to rated revolutions per minute (RPM). Units have

sealed, permanently lubricated ball or sleeve fan bearing and are statically / dynamically balanced in the fan housing

during final assembly. Fan motors are of the open drip-proof type (totally enclosed types are optional, for belt driven

only) and conform to NEMA MG-1 & MG-2. Motor starters are magnetic contactor, across-the-line type.

TYPICAL THERMOSTAT

OPTIONS AND ACCESSORIESA. Zone ControlTotal comfort zone control systems are available up to 19 zones and can provide a comfortable temperature to eachzone/room (field supplied).

B. Electric Heaters

Electric heaters are of the resistance open coil type and conform to the requirements of UL 573 or equivalent. Electricalcharacteristics, kW capacities and number of stages are as indicated. Thermal cut-outs, fusible links and airflow switchesare provided to shut-off power to heaters in case of airflow failure.

C. FiltersFilters are easily accessible through the filter access panel. Filters may be synthetic or permanent washable aluminum type, one or two inchthick (refer to model decoding for details). As an accessory, bag filter section can be provided for belt driven units (BWY07 - BWY25).

D. Discharge Air Plenum & Return Air GrilleAs an accessory, discharge air plenum with return air grilles can be provided on vertical units.

E. UV Flow™ Light EmittersThe damp & dark environment inside the AHU is ideal for the growth and development of hazardous bacteria & fungi. The UV

flow concept uses emitters of Ultra Violet light to simulate the effect of healthy sun radiation. This will inhibit the growth of these

microorganisms reducing in this manner mold related allergies and diseases. Breath safely with UV flow™.

To order the UV flow™ use the kit numbers in the table below.

F. Electronic ThermostatsGeneral Informations: Single stage or two stage thermostats provide low voltage control of one or two stage heating and/or

cooling applications. The thermostat normally displays room temperature, mode of operation and which system is currently on.

You may select different heating and cooling setpoints for the systems to maintain (example 700F in heating and 750F in

cooling). Raising or lowering the setpoints in heating or cooling is as simple as pushing a button.

The thermostat also allows you to select continuous fan operation, (useful when using an electronic air cleaner), or have

the fan on intermittent operation with the equipment.

The thermostat is best located about 1500 mm (5 Ft.) above floor level, on a partition wall (not an outside wall), and should not

be exposed to direct light from lamps, sun etc. It should be in return air stream, away from supply air registers /diffusers.

INSTALLATION INSTRUCTIONSA. GENERALBlower units are shipped completely wired. Only external power, control wiring & piping connections are needed tocomplete the installation.

B. UNIT LOCATION & ACCESS SPACEThe placement of the unit in relationship to the building is very important. A minimum of 36 inches clearance must be kepton the service access side and return air side.When making piping connections, be sure to provide clearance for electrical connections.

C. TUBING INSTALLATIONDo not remove plugs from the pipe stub out until tubing has been run and is ready for connection.

a. Make sure the tubing is round, without dent or burrs.

b. Cut tubing to the length required.

NOTE: When installing piping through walls or along side of any structural members, be sure the piping is isolated fromthese members or walls to avoid any transmission of vibration that may occur, while unit is running.

ELECTRICALSTEP 1: INSTALLATIONA) Please ensure power supply to the unit is as per unit nameplate (Volts/Ph/Hz) requirements.

Caution: Operation of the unit on improper power supply will result in damage to the unit.

NOTE: Use copper wires of proper rating for all field wiring.

Warning: Before servicing or installation of the unit, always TURN OFF all power to the unit. There may be more than

one disconnect switch. Ensure all of them are turned off. Electrical shock can cause personal injury or death.

B) Ground & power wires

Connect power wires to terminal block per wiring diagram.

Connect ground wire to the ground lug inside the control box.

C) Control wiring

Use 16 gauge color-coded wire for control wiring.

STEP 2: SEQUENCE OF OPERATIONWith power supplied to indoor unit, the unit starts responding to the thermostat mode requirement.

Cooling mode: When thermostat calls for cooling, the blower motor in the indoor unit is switched on.

As the conditioned space approaches the thermostat cooling set point, the unit cycles off.

Heating mode: When thermostat calls for heating, the blower motor in the indoor unit is switched on. The contactor for

electric heater is switched on to energize the heaters. If the room temperature is not satisfied and there are two heatersinstalled, the second heater also will be energized. Once, the conditioned space approaches the desired temperature setpoint, the heating stages cycles off.

Fan mode: In this mode the indoor unit blower motor is switched on alone.
