NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation. Note: Installer: This manual should be left with the equipment user. ! WARNING FIRE, EXPLOSION, ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury, death, and/or property damage. Installation and servicing of this equipment can be hazardous due to mechanical and electrical components. Only trained and qualified personnel should install, repair, or service this equipment. ! WARNING FIRE, EXPLOSION, ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury, death or property damage. Do not use this unit if any part has been under water. Immediately call a qualified service technician to inspect the unit and to replace any part of the control system which has been under water. ! WARNING ELECTRICAL SHOCK HAZARD Failure to follow this warning could result in personal injury or death. Before performing recommended maintenance, be sure the main power switch to unit is turned off and a lock- -- out tag is installed. OPERATING YOUR UNIT The operation of your heat pump system is controlled by the indoor thermostat. You simply adjust the thermostat and it maintains the indoor temperature at the level you select. Most thermostats of heat pump systems have 3 controls: a temperature control selector, a FAN control, and a SYSTEM or MODE control. Refer to your thermostat owner’s manual for more information. To better protect your investment and to eliminate unnecessary service calls, familiarize yourself with the following facts: 1. During heating, increasing the desired temperature setting more than 2°F(1.1°C) may cause the supplemental heaters to be turned on for a short period of time to satisfy the demand. Needless use of the supplementary heat reduces potential energy savings. 2. Ice or frost tends to form on the coil during winter heating operation. Your unit is designed to automatically melt the ice. When in this defrost cycle, it is normal for steam or fog to rise from the outdoor unit, and for water to drain from the outside of unit. Do not be alarmed! To start the unit: 1. Turn on the electrical power supply to unit. 2. Set MODE control to desired mode and select temperature. To shut off unit: Note: If the unit is being shut down because of a malfunction, call your dealer as soon as possible. 1. Set system MODE control to OFF. 2. Turn off the electrical power supply to unit. Cooling Mode With the SYSTEM or MODE 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. Heating Mode With the SYSTEM or MODE control set to HEAT, your unit will run in heating mode until the room temperature is raised to the level you have selected. Of course, your unit will run for longer periods to maintain a comfortable environment on cooler days and nights than on moderate ones. Supplemental Heat Your unit is your primary heating source. Your system may also be equipped with a supplemental heating source such as electric heat. On cold days and nights, your system will automatically turn on the supplemental heat, as needed, in order to maintain the level of comfort you have selected. When your heat pump needs additional heat to keep you comfortable your thermostat will turn on the supplemental heat (if equipped). Defrost Mode When your unit is providing heat to your homeor officeand theoutdoor temperature drops below 45°F(7.2°C), moisture may begin to freeze on the surface of the coil. If allowed to build up, this ice would impede airflow across the coil and reduce the amount of heat ab 2 sorbed from the outside air. So, to maintain energy- --efficient operation, your unit has an automatic defrost mode. The defrost mode starts at a preset time interval of 60 minutes, although, it may be reset to 30, 90 or 120 minutes. Defrost will start at the preset time only if the ice is sufficient to interfere with normal heating operation. After the ice is melted from the coil, or after a maximum of 10 minutes in defrost mode, the unit automatically switches back to normal heating operation. Do not be alarmed if steam or fog appears at the outdoor unit during defrost mode. Water vapor from the melting ice may condense into a mist in the cold outside air. During certain weather conditions such as heavy snow and freezing rain it is not uncommon for ice to build up on the unit grille. This is normal for these weather conditions. Do not attempt to remove the ice from the unit grille. This condition will not affect the proper function of the unit and will clear within a few days. Emergency Heating Mode In the event of primary unit heat failure, the emergency heat mode allows your supplemental heating source to keep your home or office warm until your unit can be serviced.
