SPLIT SYSTEM HEAT PUMP
USER’S
MANUA
Congratulations . . .Congratulations . . .
On your purchase of our Heat Pump. This energy efficient system has been precision designed , manufactu red of high quality
materials and has passed many vigorous inspections and tests to ensure years of satisfactory service.
Please read this booklet thoroughly. It will help you unders tand your heat pump and will tell you how to operate it ef ficiently
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 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, trouble-free operation.
Your system is fully automatic. Set the
thermostat and forget it. And it’s automatically protected from damage by
voltage fluctuations or excessive heating 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 moisture
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.
Set your thermostat for heating or for
cooling. Then set it for the desired temperature. 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 w ill increase your operating cost substa nti a lly.
CAUTION: 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 the outdoor temperature in the range
of 20 to 30° or below, the outdoor unit will
generally run 100% of the time.
All E*FH systems are equipped with balance point control to provide even mor e
efficient operation. This control will prevent the electric heater from being energized when the outdoor air is above
some predetermined temperature setting (0 to 45°F). At higher temperatures,
your system will provide all the heat your
home will ever need. At lower temperatures, the supplemental electric heat will
be energized to keep your home comfortable.
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. The
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°.
Comfort sensations vary with individuals. The lower the indoor temperature
desired, the greater will be the number
of hours your unit must operate.
Set your thermostat 2 or 3 °F below nor mal 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 oversized
system would operate much less efficiently at all other conditions.
SYSTEM OPERATION
Your thermostat puts full control of the
comfort level in your home at your fingertips.
DO NOT switch your thermostat rapidly
“On” and “Off” or between “Heat” to
“Cool”. This could damage your equipment. Always allow at least 5 minutes
between changes,
