Congratulations . . .
On your purchase of one of the most versatile heat pump systems available in the industry today. This Stealth series high effi- ciency system has been precision designed, manufactured of high quality materials and has passed many vigorous inspections and tests to ensure years of satisfactory service.
This booklet is meant to increase your understanding of your system, tell you how to operate it efficiently and how to obtain the greatest measure of comfort at the lowest operating expense. Please read this booklet thoroughly.
We appreciate your interest in our product and your decision to purchase our system. Enjoy your comfort.
This Heat Pump has been specially developed and built as a heat pump - to meet the dual needs of heating and cooling. It's not just an air conditioner with extra parts. That's why you can rely on efficient,
Your system is fully automatic. Set the thermostat and forget it. And it's auto- matically protected from damage by voltage fluctuations or excessive heat- ing or cooling demands.
Your split system heat pump consists of two units - one installed outdoors and one installed indoors. The indoor unit may be installed in a basement, attic, or crawl space.
HOW YOUR HEAT PUMP WORKS
If your hand is wet and you blow on it, it feels cool because some of the mois- ture is evaporating and becoming a vapor. This process requires heat. The heat is being taken from your hand, so your hand feels cool.
That's what happens with a heat pump. During the cooling cycle, your system will remove heat and humidity from your home and will transfer this heat to the outdoor air.
During the heating cycle, your system will remove heat and humidity from the outdoor air and will transfer this heat to your home. This is possible because even 0°F outdoor air contains a great deal of heat. Remember that your heat pump doesn't generate much heat, it merely transfers it from one place to another
SYSTEM OPERATION
THERMOSTATS
Though thermostats may vary widely in appearance they are all designed to perform the same basic function, to control the operation of your air condi- tioning system. Regardless of size or shape, each thermostat will feature a temperature indicator; a dial, arm or push button for selection of the desired
temperature; a fan switch to choose the indoor fan operation; and a comfort switch for you to select the system mode of operation.
Your new unit will require a three stage heating / two stage cooling thermostat for optimum efficiency and energy sav- ings. Please be aware that many dif- ferent thermostats operate on batteries or “power stealing” princi- pals. UPG can not support such models to be trouble free when used with this unit.
The following illustrations and discus- sion will aid you to determine which type of thermostat you have for your system.
A complete operating instruction is pro- vided by the manufacturer for each thermostat. Familiarize yourself with its proper operation to obtain the maxi- mum comfort with a minimum of energy consumption.

FAN OPERATION SELECTION
A
AUTO
With the thermostat fan switch set to “AUTO”, the fan will run intermittently as required for either heating or cool- ing. This position will provide the low- est operating cost. If you purchased one of the recommended thermostats, they have an Intelligent fan mode which continually circulates the air dur- ing occupied modes or when you are
at home, and can cycle the fan during unoccupied mode or during the night while you sleep to further conserve energy.
ON
CONTINUOUS FAN OPERATION: With the thermostat fan switch set to “ON”, the indoor fan will not shut off. However, the cooling and heating sys- tems will still operate as required by room temperatures. This provides con- tinuous air filtering and more even tem- perature distribution to all conditioned spaces.
FAN ONLY OPERATION: On moder- ate days, usually during spring and fall, when neither heating nor cooling is required, you may want to run only the fan to ventilate, circulate and filter the air in your home or building. Set the comfort control switch to “OFF” and the fan switch to “ON”. Be sure to return the switches to their original positions for normal operation.
The Main power to the sys- tem must be kept “ON” at all times to prevent damage to the outdoor unit compressor. If necessary, the thermostat control switch should be used to turn the system “OFF”. Should the main power be disconnected or interrupted for 8 hours or longer, DO NOT attempt to start the sys- tem for 8 hours after the power has been restored to the outdoor unit. If heat is needed during this 8 hour period, use emergency heat.
HEATING CYCLE
With the thermostat in the heating position, and the outdoor temperature in the range of 20 to 30° or below, the outdoor unit will generally run 100% of the time.
