First Co. commercial – duty SVW chilled or hot water blower coil units are designed for installation within the conditioned area or as remote units with duct systems.

SVW SERIES
First Co. commercial – duty SVW chilled or hot water blower coil units are designed for installation within the conditioned area or as remote units with duct systems. Standard 4 row coils can be used for cooling or heating. These air handlers are compact, with large removable panels for installation and ease of service. Separate filter panels are provided on both sides of unit. Optional accessories include 6 row cooling coils, hot water coils, various motor options, mixing boxes, motor starters, and discharge plenums. All models feature positive slope drain pans. Standard models are available in 8 popular sizes 800 through 8000 nominal CFM (2 through 20 tons). All standard models are ETL listed and rated in accordance with ARI Standard 430.
CABINET
Fabricated of heavy gauge galvanized steel. Seismic resistant mounting brackets are standard on 2-5 ton models.
BLOWER
Resiliently mounted, heavy duty, double inlet, forward curved blade, centrifugal type. Each wheel is dynamically balanced for smooth, quiet operation. All blowers are belt driven with field adjustable pulleys to permit variations in static pressure and air requirements. All blowers have ball bearings.
COILS
Fabricated of 3/8” or 1/2” OD seamless copper tubes mechanically expanded to highly efficient aluminum fins to maximize heat transfer. All coils have manual air vents. All models have positive slope drain pans.
INSULATION
The entire interior of the cabinet is insulated with one (1) inch insulation.
FILTER
One inch throw away filters are provided as standard in all 2 – 5 ton units. One inch permanent filters are provided as standard in all 7-1/2 – 20 ton units.
Filters can be changed without tools. Space available for 2”.
FACTORY WIRED
All standard motors are field or factory installed and wired at voltage specified by customer. (If not specified, multi-voltage motors will be wired at highest voltage)
MOTOR
Standard motor is 1725 RPM. The adjustable motor mount permits easy belt adjustment. A variable pitch pulley allows balancing of the system to the desired CFM. Standard motors have internal overload protection. Therefore, units shipped with standard motors will be ETL listed. Most non-standard motors (i.e. 575V, 2-speed, TEFC, some 50 Hz., etc.) are not available with internal overload protection. Therefore, most units shipped with non-standard motors can be ETL listed with the addition of a factory installed motor starter (contact the factory for starter information and ETL verification.)
MISCELLANEOUS – Slotted mounting rails for easy installation. Rails are turned down 1/2” on each end for safer and easier installation.
– 4 x 4 junction box accepts a field installed (24/120V) relay / transformer for low voltage control.
– 3/4 inch NPT drain connections on both sides of cabinet.
– Header connections on the right side as standard.
Knockouts are provided for conversion to the left side. (Looking with air flow).
– Drain pans are coated for corrosion protection.

UNIT SELECTION PROCEDURE

1. Complete as much of the “INFORMATION REQUIRED FOR UNIT SELECTION” on page 2 as possible.
   Example:
   INFORMATION REQUIRED FOR UNIT SELECTION
   System Type ( circle one) : 2 – pipe (1 coil ) or 4 – pipe ( sep. htg. & clg. coils )
   CFM 3900
   E.S.P. .80 MOTOR: HP:____VOLTAGE:230PHASE:3
   COOLING: INDOOR: DB WB ____OUTDOOR:
   DB____
   TOTAL BTUH____158,000SENS. BTUH ____ GPM __EWT 45
   HEATING:
   TOTAL BTUH ____GPMEWTEAT
   MISC:

2. Select the unit model that meets the required total MBH cooling and heating at the required conditions from tables on pages 16 – 23 (capacities and air are the same for SHW and SVW models).
   Example: Required clg. capacity = 158,000 BTUH clg. @ 45 degree EWT Unit selected = 120SHW6

3. Refer to page 7 for the balance of the selection procedure: If the required CFM falls within the range for the selected model, proceed to number 4. If not, use the First Co. Computer Selection Program or contact the factory for assistance.

4. Determine the required motor horsepower by matching the selected model (i.e. 120SHW6) with the closest CFM at the required External Static Pressure (ESP). Note the horsepower (HP) at the top of the CFM range that is needed.
   Example: Required CFM is 3900 at .80 ESP.
   HP required = 2 HP

5. Select the motor voltage, phase, and horsepower and then the appropriate Motor Drive Assembly Number that applies.
   Example: Above example requires Motor Drive Assembly Number 984120-G3

Notes:

1. All drain connections are 3/4” MPT and located on same side as coil connections.
2. All units have knockouts on both sides for either (standard) or left side coil stub outs.
   (Looking with airflow) All coil connections must be on the same side of the unit.

Notes:

1. Shaded area indicates the R.P.M. and C.F.M. range of the standard motor and pulleys.

2. To determine available brake horsepower (BHP), take above nominal HP and multiply as follows:
   For 1/4 HP to 3/4 HP motors: BHP = nominal X 1.25
   For 1 HP to 5 HP motors: BHP = nominal X 1.15

3. Special pulleys and motors can be factory furnished at an additional charge.

4. Horsepower tabulated indicates minimum recommended motor H.P.
   Rated in accordance with ARI Standard 430.

HOT WATER HEATING CORRECTION FACTORS

Notes:

1. To determine heating capacity at other than 180 deg. E.W.T. and 70 deg. E.A.T. multiply the selected heating capacity at 180 deg. times the appropriate correction factor from above chart.
2. These correction factors may be used on all First Co. published 180 deg. heating capacities.
3. When SHW units are used for hot water heating the leaving air temperature must not exceed 150 degrees. At high altitude conditions, blower motor may cutout at a lower LAT. Contact factory for information.

GUIDE SPECIFICATIONS

Furnish and install First Co. SVW Series Blower – Coil units as indicated on the plans.
CABINETS
Cabinets shall be manufactured of heavy gauge galvanized steel. The entire interior of the cabinet shall be insulated with one inch thick IAQ type insulation. Removable access panels shall be provided on both sides of the cabinet for maintenance and service. All cabinets shall have 2” supply and 1” return flanges.
INSULATION
The entire interior of the cabinet shall be insulated with one (1) inch insulation. This insulation must meet the requirements of ASTM C 1071, ASTM G 21, ASTM G 22, NFPA 90A, UL-181, and the cleaning practices of NAIMA.
MOTOR / BLOWERS
Blowers shall be resiliently mounted, with ball bearings, forward curved blade, and of centrifugal type. Each wheel shall be dynamically balanced for smooth, quiet operation. Blowers shall be belt driven with field adjustable pulleys to permit variations in static pressure and air requirements. Standard motors are 1725 RPM either single or three phase. All motors to be field or factory installed and wired at voltage specified by customer.
COILS
All SVW series coils shall consist of aluminum fins mechanically bonded onto 3/8” or 1/2” OD seamless copper tubing. All coils shall be leak tested at 350 PSIG minimum air pressure. Manual air vents shall be standard on all coils.
Drain pans shall be coated for corrosion protection.
FILTERS
One inch throw away filters are standard in 2-5 ton SVW units. One inch permanent filters are provided as standard in 7-20 ton SVW units. Filters shall be accessible without tools.
LISTING
All standard motors are ETL Listed. All air handlers shall be rated in accordance with ARI Standard 430. Standard motors have internal overload protection. Therefore, units shipped with standard motors will be ETL listed. Most non-standard motors (i.e. 575V, 2-speed, TEFC, some 50 Hz., etc.) are not available with internal overload protection. Therefore, most units shipped with non-standard motors can be ETL listed with the addition of a factory installed motor starter (contact the factory for starter information and ETL verification.)
