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.

The above square footages are based on 300 F.P.M. face velocity. If permanent filters are used, size per mfg. recommendation with clear resistance of 0.05" WC. 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 weatherproof 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 18. 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: Unit must be grounded for ignitor to operate properly. Gas pipe to unit is not an adequate ground. Ground the unit internally as provided. See wiring diagram for location. 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 Figures 3 and 4 for the control entry location. Make connections as shown on the unit wiring diagram and in Figure 18. Do not short thermostat wires since this will damage the control transformer. Recommended wire sizes and lengths for installing the unit thermostat are provided in Table 5. The total resistance of these low voltage wires must not exceed one (1) ohm. Any resistance in excess of 1 ohm may cause the control to malfunction because of the excessive voltage drop.

IMPORTANT: Upon completion of wiring check all electrical connections, including factory wiring within the unit, make sure all connections are tight. Replace and secure all electrical box covers and access doors before leaving the unit or turning on the power to the unit. Page 16 Page 17 YCZ-F FIELD WIRING DIAGRAM the Thermostat System Switch until power has been applied long enough to evaporate any liquid R-22 in the compressor. It is recommended that the sump heater be energized for eight (8) hours prior to starting. After all electrical wiring is complete, set the thermostat system switch in the OFF position so that the compressor will not run and then apply power by closing the system main disconnect switch. This will activate the compressor sump heat. Do not change ELECTRICAL WIRING i START - U P PRE-START QUICK CHECKLIST . Is the unit properly located and level with the proper clearance? See Figure 4. . Is the duct work correctly sized, run, taped, insulated, and weatherproofed with proper unit arrangement? See Ductwork Installation section. .
