1. Set UI control to OFF. 2. Turn off gas supply to unit. 3. Turn off electrical power supply to unit. OPERATING YOUR UNIT The operation of your unit is controlled by the Evolutiont UI. You simply program theUIand it maintainsthe indoortemperature atthe level you select. See UI manual for detailed instructions. To better protect your investment and to eliminate unnecessary service calls, familiarize yourself with the following facts: Step 1—Cooling Mode With the SYSTEM control set to COOL, your unit will run in cooling mode until the indoor temperature is lowered to the level you have selected. On extremely hot days, your unit will run for longer periods at a time and have shorter “off” periods than on moderate days. Step 2—Hybrid Heating Mode Your Hybrid Heat system combines the strengths of two heating sources; an electric heat pump and a gas furnace. A Hybrid Heat system provides more control over your monthly energy bills by allowing you to choose the most economical method of heating. As conditions change, the system automatically switches between the two sources to maintain greater efficiency than with a single- --source heating system. 2 With the UI control set to HEAT, your unit will normally operatethe electric heat pump until the room temperature is raised to the level you have selected. If the demand for heat cannot be met by the electricheatpump, yourUIcontrolwillautomaticallyswitchtogas heat until the call for heat is satisfied. On colder days, your system may automatically switch to gas heat as the primary heating source to maximize the overall system efficiency and maintain your comfort level. MAINTENANCE AND SERVICE This section discusses maintenance that should be performed on your system. Most maintenance should be performed by your dealer. You, as the owner, may wish to handle some minor maintenance for your new unit. Routine Maintenance All routine maintenance should be handled by skilled, experienced personnel. Your dealer can help you establish a standard procedure. To assure proper functioning of the unit, flow of condenser air must not be obstructed from reaching the unit. Clearance from the top of the unit is 48 in. Clearance of at least 36 in. is required on sides except the power entry side (42 in. clearance) and the duct side (12 in. minimum clearance). Maintenance and Care for the Equipment Owner Before proceeding with those things you might want to maintain yourself, please carefully consider the following: ! WARNING FIRE, EXPLOSION, ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury, death or property damage. BEFORE SERVICING OR PERFORMING MAINTENANCE ON YOUR UNIT: 1. TURN OFF GAS SUPPLY TO YOUR UNIT. 2. TURN OFF ELECTRICAL POWER TO YOUR UNIT. WARNING! ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in death, personal injury and/or property damage. When removing access panels or performing maintenance functions inside your unit, be aware of sharp sheet metal parts and screws. Although special care is taken to reduce sharp edges to a minimum, be extremely careful when handling parts or reaching into the unit. Air Filters The air filter(s) should be checked every 3 or 4 weeks and changed or cleaned whenever it becomes dirty. Dirty filters produce excessive stress on the blower motor and can cause the motor to overheat and shut down. This unit must have air filters in place before it can be operated. These filters can be located in one of at least two places. In many applications, the installer will provide return air filter grilles mounted on the wall or ceiling of the conditioned structure. In the instance of filter grilles, the filters can simply be removed from the grille and replaced. The other typical application is an accessory filter rack installed inside the unit itself. The following information is given to assist in changing filters used in these internal filter racks. Table 1 indicates the correct filter size for your unit. Refer to Fig. 2 to access filters installed in the accessory filter rack. Table 1—Indoor Air Filter Data 24x30x1 677B042- ---060 24x36x1 UnitSizeFilterSize677B024---03020x24x1677B036 To replace or inspect filters in accessory filter rack (See Fig. 2): 1. Remove the filter access panel using a 5/16- --in. nut driver. 2. Remove the filter(s) by pulling it out of the unit. If the filter(s) is dirty, clean or replace with a new one. When installing the new filter(s), note the direction of the airflow arrows on the filter frame. If you have difficulty locating your air filter(s) or have questions concerning proper filter maintenance, contact your dealer for instructions. When replacing filters, always use the same size and type of filter that was supplied originally by the installer.
