The outside ductwork must be weatherproofed between the unit and the building. When attaching ductwork to a horizontal unit, provide a flexible watertight connection to prevent noise transmission from the unit to the ducts. The flexible connection must be indoors and made out of heavy canvas. NOTE: Do not draw the canvas taut between the solid ducts.

Fiberglass dust and ceramic fibers are believed by the State of California to cause cancer through inhalation. Glasswool fibers may also cause respiratory, skin, or eye irritation. CONDENSATE DRAIN PIPING A 3/4-inch female NPT condensate drain connection is provided on the evaporator access panel end of the unit. See TYPICAL CONDENSATE DRAIN PIPING e Figure 4. Provide a trap and fill it with water before starting the unit to avoid air from being drawn through. Follow local codes and standard piping practices when running the drain line. Pitch the line downward away from the unit. Avoid long horizontal runs. See Figure 13. NOTE: Do not use reducing fittings in the drain lines. The condensate drain must be: . Made of 3/4" pipe size. . Pitched 1/4" per foot to provide free drainage to convenient drain system. . Trapped. . Must not be connected to closed drain system. 3/4" PVC OR COPPER TUBING AND FITTINGS 1-1/2" MIN. Page 11 FILTER INSTALLATION AIR FILTERS Filters are to be used with the WCY024-060G heating/cooling units. The basic unit does not have filters in it. However, a filter frame accessory is offered that will allow filters to be installed within the unit. Otherwise a filter rack must be installed by the installer in the duct work. Affix the filter label supplied with the unit adjacent to the filter area.

ELECTRICAL WIRING ELECTRICAL CONNECTIONS Electrical wiring and grounding must be installed in accordance with local codes or, in the absence of local codes, with the National Electrical Code ANSI/NFPA 70, Latest Revision. ELECTRICAL POWER It is important that proper electrical power be available for the unit. Voltage variation should remain within the limits stamped on the unit nameplate. DISCONNECT SWITCH Provide an approved weather-proof disconnect either on the side of the unit or within close proximity and within sight of the unit. OVER CURRENT PROTECTION The branch circuit feeding the unit must be protected as shown on the unit rating plate. POWER WIRING The power supply lines must be run in weathertight conduit to the disconnect and into the bottom of the unit control box. Provide strain relief for all conduit with suitable connectors. Provide flexible conduit supports whenever vibration transmission may cause a noise problem within the building structure. Be sure all connections are made tight. See Figure 14. NOTES: For branch circuit wiring (main power supply to unit disconnect), wire size for the length of run should be determined using the circuit ampacity found on the unit nameplate and the N.E.C. For more than 3 conductors in a raceway or cable, see the N.E.C. for derating the ampacity of each conductor. GROUNDING: THE UNIT MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES OR THE NATIONAL ELECTRIC CODE. NOTE: Ground the unit internally as provided. See wiring diagram for location. Page 12 CONTROL WIRING (CLASS II) Low voltage control wiring should not be run in conduit with power wiring unless Class 1 wire of proper voltage rating is used. Route the thermostat cable or equivalent single leads of No. 18 AWG colored wire from the thermostat subbase terminals through the rubber gromment on the unit. See Figure 5 for the control entry location. Make connections as shown on the unit wiring diagram and in Figure 14. Do not short thermostat wi...
