KCASERIES6STORM WINDOW APPLICATIONSIf the window is blocked by a storm window frame andthe storm window frame cannot be removed, a mount-ing board (field provided) will need to be added to thewindow sill. The air conditioner needs to be pitcheddownward to the back in order for condensate to drainproperly. The frame of the storm window (or any otherobstruction) must be at least 3/ 4-in. lower than thewindow sill. If the storm window frame is not at least3/4 -in. below the window sill, then a mounting boardwill need to be added to raise the height of the windowsill. See Fig. 9. The board will need to be provided andcut by the installer.1. The wood mounting board should be a minimumof 1 1/2 -in. wide and should run the length of thewindow. The thickness of the mounting board isdependent on the height of the storm windowframe. The mounting board should raise the frontof the air conditioner high enough so that the unitwill be pitched downward at least 5/8 -in. when theback of the unit is resting on the storm windowframe. See Fig. 9.2. Cut the wood mounting board to fit the window.3. Install the wood mounting board on the windowusing 2 field-provided nails or screws.4. Drain holes or slots in storm window frame mustnot be caulked or painted shut. Holes are neededto drain rain water and condensate. Ensure thattrapped water can drain out.OPERATIONThe mechanical-type control is used on your KCA051DCarrier air conditioner. The electronic-type control isused on your KCA061P and KCA081P Carrier airconditioner. Refer to the correct section for your airconditioner.The mechanical controls consist of a dial which can beset to different modes of cooling and fan operation anda thermostat dial to set desired room temperature. SeeFig. 10.The electronic control consists of a control panel and aremote control. Both the control panel or the remotecontrol can be used to set cooling and fan modes andadjust the desired temperature. See Fig. 11. Otheradditional features are provided.MECHANICAL CONTROLS■ TURN UNIT OFF — To turn the unit OFF, set thedial to the OFF position. The air conditioner will notoperate when the dial is set to OFF.■ COOLING MODES — The air conditioner can beset to two different cooling modes — LOW COOL orHIGH COOL. HIGH COOL mode is recommended forvery warm days or when a fast initial cooling of theroom is desired. LOW COOL mode is recommended onslightly warm days or after the room temperature hasreached its desired setting.NOTE: After setting a mode, allow 3 minutes to passbefore changing modes.■ FAN MODE —The air conditioner can be set toLOW FAN or HIGH FAN mode. In FAN mode, the fanoperates to circulate the air in the room, but there isno cooling operation. This mode is used to keep theroom air circulating when cooling is not needed. Thefan can be set to HIGH FAN for maximum air circula-tion without cooling or LOW FAN for moderate air cir-culation without cooling.■ THERMOSTAT — The thermostat dial is numberedfrom 1 to 9. The lowest (least cooling) setting is 1. Thehighest (most cooling) setting is 9. Turn the thermo-stat dial clockwise to lower the room temperature.Turn the dial counterclockwise to raise the roomtemperature.ELECTRONIC CONTROLSEither the remote control or the control panel on theair conditioner can be used. The battery of the remotecontrol will need to be installed before it can be used.FIGURE 9 — STORM WINDOW APPLICATIONS THERMOSTATKNOB MODE KNOBMODETHERMOSTATFIGURE 10 — MECHANICAL CONTROLS
