COMPACT DIMENSIONS Ideal to fit into tight spaces. EASY MAINTENANCE / ONE SIDE ACCESS Filters can be easily removed by sliding. Piping and controls are on one side for easy access. BACK AND BOTTOM RETURN AIR OPTIONS SINGLE COIL FOR RH & LH APPLICATIONS (FIELD CHANGEABLE FOR RH & LH APPLICATIONS) SPLIT COILS, CHILLED + HOT WATER OPTIONS VALVE PACKAGES FOR PIPE & 4 PIPE SYSTEMS WIDE RANGE OF HEATER SIZES QUIET, PULSE FREE AIR DELIVERY Centrifugal fans that are statically and dynamically balanced, handle up to 0.5 w.g. external static pressure allowing you to keep the unit away from your comfort zone. STANDARD SPECIFICATIONS UNIT CONSTRUCTION These units are fabricated of heavy gauge galvanized steel to ensure lasting durability and dependable performance with minimum maintenance. The panels are insulated to provide positive protection against sweating and maximum damping of air noise. This unit is designed for those concealed overhead installations which require supply ductwork. A duct collar is provided into the front panel for supply air duct connection. The standard arrangement provides return air from the rear side. This arrangement may be reversed to provide bottom return air by simply interchanging the bottom and rear panel. This reversal can be easily accomplished in the field. Access to the blower motor assembly is provided through the removable bottom panel from where the complete fan/motor can be removed for servicing. FANS The centrifugal, forward curved, double width fan wheels are statically and dynamically balanced for quiet and smooth performance. Blower housing is rugged galvanized steel to provide added rigidity and assure quiet & smooth operation. 3 GE_ACWL_series.indd 3 3// : PM

4 STANDARD SPECIFICATIONS MOTORS Motors are permanent split capacitor type with three speed windings and built-in thermal overload protection. The bearings are of sleeve type. FILTERS All models are furnished with / thick permanent washable type aluminum filters as standard. COILS Coils are 3/8 OD copper tubing, constructed of enhanced copper tubes and mechanically bonded to aluminum As fins. an option, corrugated copper fins or coated aluminum fins may be provided. Manual air vents are provided on all chilled water coils. The standard chilled water coil is 3 rows for all models & 4 row chilled water coil is also provided as an option. A 4 pipe coil consisting of 3 rows of cooling coil and row of heating coil is used for heating application. Each coil is pressure tested in the factory at not less than 300 psi (00 kpa) air pressure. Coils conform to ARI 40. DRAIN PAN The condensate drain pan is fabricated of 8 gauge galvanized steel. The drain pan is powder coat painted. The outer surface is thermally insulated. DRIP LIP The purpose of a drip-lip is to capture any condensate from the valve packages and direct it to the drain pan. It is fabricated of a single metal formed to fit on the side of the drain pan. They may be installed in the field and should always be pitched towards the drain pan to assure proper drainage. This will be supplied loose for field installations along with valve packages. OPTIONS ELECTRIC HEATERS The heater element is of the resistance open coil type. Thermal overheat cut-outs and fusible links are provided to shutoff power to heaters in case of airflow failure. VALVE PACKAGES Valve packages are available as an option (3D for two pipe system and 4D for four pipe systems). These valves can be factory installed or supplied loose for field installation. THERMOSTAT An attractive wall mount three speed electronic thermostat with all required functions and features for safe and smooth operation which can be used for cooling & heating requirements. 4 GE_ACWL_series.indd 4 3// : PM

18 INSTALLATION The complete shipment should be inspected for damage. Any damage, visible or concealed, should be reported immediately to the delivery man or driver and noted on the shipping invoice. Place unit in position and make sure that unit is level. This is important to assure proper drainage and operation. Slots provided in the mounting brackets should be used for installing the units. ELECTRICAL Please ensure power supply (V-Ph-Hz) to the unit is as per unit nameplate requirements. Caution: Operation of the unit on improper power supply will result in damage to the unit. Warning: Before installation or servicing, always TURN OFF all power to the unit. There may be more than one disconnect switch. Ensure all of them are turned off. GROUND & POWER WIRES Connect power wires as per wiring diagram. Connect ground wire to the ground lug inside the control box. MAINTENANCE COIL Coil may be cleaned by removing and brushing between fins with a stiff wire brush. Brushing should be followed by cleaning with vacuum cleaner. The coil may also be cleaned by using a high pressure air, if compressed air source is available. It should be pointed out that if air filters are used and periodically cleaned, the coils will not be clogged up prematurely. DRAIN PIPE Drain pipe should be checked before summer operation of unit. If it is clogged, steps should be taken to clear the debris so that condensate will flow out easily. A standard pipe cleaner for / ID pipe may be used. Periodic checks of the drain pipe should be taken during summer operation, as there is a possibility of it becoming clogged with dirt. FILTER CLEANING Remove access panel, slide filter out of filter rack, and clean as follows: Tap filter on solid surface to dislodge heavy particles. Wash under stream of hot water. If filter has been put to exceptional service, a mild solution of Sal-Soda, Tri-Sodium Phosphate or any other commercial solvent can be used. Set filter on end with slots in frame down, which allows it to drain. Filters should dry thoroughly before reuse. REPLACEMENT PARTS When writing for replacement parts, refer to model number and serial number on the nameplate of the unit. 8 GE_ACWL_series.indd 8 3// : PM
