Congratulations...

on your purchase of our heat pump. This energy efficient unit has been precision designed, manufactured of high-quality materials and has passed many rigorous inspections and tests to ensure years of satisfactory performance. Please read this booklet thoroughly. It will help you understand your heat pump and will tell you how to operate it efficiently and how to obtain the greatest measure of comfort at the lowest operating expense. We appreciate your interest in our products and your decision to purchase our heat pump. Enjoy your comfort.

This heat pump has been specially developed and built to meet dual needs of heating and cooling. That’s why you can rely on efficient, trouble-free operation.

Your system is fully automatic. Set the thermostat and forget it. And it’s automatically protected against damage by voltage fluctuations or excessive heating or cooling demands.

GENERAL INFORMATION

HOW YOUR HEAT PUMP WORKS

If your hand is wet and you blow on it, it feels cool because some of the moisture is evaporating and becoming a vapor. This process requires heat. The heat is being taken from your hand, as 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 structure 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 structure. Remember that your heat pump doesn’t generate much heat, it merely transfers it from one place to another.

*This is possible because even 0°F outdoor air contains a great deal of heat.

SYSTEM OPERATION

Your thermostat puts full control of the comfort level in your structure at your fingertips.

Set your thermostat for heating or cooling. Find the temperature that is most comfortable for you, and then leave your thermostat alone. Manually moving the thermostat up or down to extreme settings will not speed up temperature changes. Avoid moving the thermostat up during heating - particularly where a demand type electric meter is installed. This will increase your operating cost substantially.

The Main power to the system 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 system 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 outdoor temperature in the range of 20 - 30° or below, the outdoor unit will generally run 100% of time.

When the outdoor air is cool and moist, frost may form on the surface of your outdoor coil. When this frost builds to a certain point, your system will switch to a defrost cycle. Although you may feel cooler air coming from your registers, DO NOT adjust your thermostat. This frost will melt quickly, and your system will return to normal operation automatically.

COOLING CYCLE

Switch your thermostat to cool. Select a comfortable thermostat temperature setting, typically between 75 and 80 degrees. Comfort sensations vary with individuals.The lower the indoor temperature desired, the greater the number of hours your unit must operate.

Set your thermostat 2 or 3°F below normal several hours before entertaining large groups during hot weather. People give off considerable heat and moisture.

On an extremely hot day, the indoor temperature may rise 3 to 6°F above the thermostat setting. Properly selected equipment does not have the capacity to maintain a constant indoor temperature during this peak load. Over-sizing your system to handle this peak load isn’t practical because the over-sized system would operate much less efficiently at all other conditions.

AIDS TO MAXIMUM OPERATING EFFICIENCY

HEATING CONSERVATION

For the most efficient operation, keep storm windows and doors closed all year long. They not only help to insulate against heat and cold, but they also keep out dirt, pollen and noise.

Closing drapes at night and keeping fire place dampers closed when necessary, will help you to retain the air you have already paid to heat.

COOLING CONSERVATION

To comfortably cool your home, your heat pump must remove both heat and humidity. Don’t turn your system off even though you will be away all day. On a hot day, your system may have to operate between 8 and 12 hours to reduce the temperature in your home to a normal comfort level.

Keep windows closed after sundown. While the outdoor temperature at night may be lower than indoors, the air is generally loaded with moisture which is soaked up by furniture, carpets and fabrics. This moisture must be removed when you restart your system.

The hotter the outside temperature, the greater the load on your system. Therefore do not be alarmed when your system continues to run after the sun has set on a hot day. Heat is stored in your outside walls during the day and will continue to flow into your home for several hours after sunset.

Use your kitchen exhaust fan when cooking. One surface burner on “High” requires one ton of cooling. Turn on your bathroom exhaust fan while showering to remove humidity. You can also help your system in the summer by closing drapes or blinds and lowering awnings on windows that get direct sunlight.

MAINTENANCE

Prior to any of the following maintenance procedures, shut off all power to the unit.

In order to insure long and trouble free service from your system, we recommend periodic inspection, cleaning, lubrication and adjustment by your installing Dealer/Contractor. Be sure to ask about this service.

For those buildings with in-house maintenance, please follow the instructions listed below to care for your system.

LUBRICATION

Both the indoor blower motor and outdoor fan motor are permanently lubricated and require no maintenance.

FILTER CARE

Filters must always be used and must be kept clean. When filters become dirt laden, insufficient air will be delivered by the blower, decreasing your units efficiency and increasing operating costs and wear-and- tear on the unit and controls.

AIR FILTERS

Single phase units are shipped without a filter and is the responsibility of the installer to place a high velocity filter into the return air duct system. If an economizer or outdoor air accessory is used, install a filter/frame kit (1FF0114). See Figure 1. The filter rack and filters are standard on three phase units.

Filters should be checked monthly especially since the unit is used for both heating and cooling. You must have high velocity permanent filters. High velocity permanent filters may be removed for cleaning. Remove filters, vacuum or wash with a stream of water directly from a faucet or hose. Allow filters to dry and replace.

High velocity permanent filters should last for many years. However, if they ever need replacing, they must be replaced with the same size and type.

NOTE: Filters must be installed with Air Flow arrows pointing inward toward the indoor coil.

REGISTERS

Supply and return air registers must be open when the unit is in operation. Furniture must not block airflow in or out of the registers.

CONDENSER COIL

An annual check and cleaning of the outdoor coil should be done. Clean any debris and dirt from the outside coil face with a brush being careful not to damage the fins. If extremely dirty, a hose can be used to wash the coil from the inside out while brushing a soapy solution on the outside.

BLOWER ASSEMBLY

Even with good filters properly in place, blower wheels and motors will become dust laden after long months of operation. The entire blower assembly should be inspected annually. If the motor and wheel are heavily coated with dust, they can be brushed and cleaned with a vacuum cleaner.

CHARACTERISTICS OF HEAT PUMPS

A CONSTANT HEAT

Heat pumps have a noticeably cooler supply air temperature than furnaces. The common practice of oversizing furnaces contributes to an "off-and-on-again" operation with short blasts of hot supply air. The heat pump system is sized more closely to the heating needs of your home. Heat is supplied at a lower temperature over a longer period of time to provide a more constant heat, and it may give you the impression that your system "never stops running".
