Carrier WEATHERMASTER 2000 - Important Facts

WELCOME TO EFFICIENT
YEAR-ROUND COMFORT
Congratulations on your excellent choice and sound invest¬
ment in year-round home comfort!
Your new heat pump represents both the latest in engineer¬
ing development and the culmination of many years of expe¬
rience from one of the most reputable manufacturers of
comfort systems.
Your new unit is among the most energy-efficient and reli¬
able heat pump products available today. To assure its
dependability, spend just a few minutes with this booklet
now. Learn about the operation of your heat pump, and the
small amount of maintenance it takes to keep it operating at
its peak efficiency.
With minimal care, your new heat pump will provide you
and your family with year-round home comfort—both now
and for years to come.
YOUR COMFORT SYSTEM
Identifying Your System
Take the time to familiarize yourself with the type of sys¬
tem you have. This knowledge will be of use in understand¬
ing the basic operation of your new heat pump.
The triple split-system type has an indoor fan coil, indoor
compressor section and an outdoor unit, two of which con¬
tain a coil. These units are interconnected by refrigerant
tubes, as shown in Fig. 1.
Each unit has a rating plate affixed to it. A rating plate pro¬
vides necessary information for specific identification of a
unit. You should familiarize yourself with the product,
model, and serial numbers listed on each rating plate.
IMPORTANT FACTS
To better protect your investment and to eliminate unneces¬
sary service calls, familiarize yourself with the following
facts:
• Your heat pump system should never be operated with¬
out a clean air filter properly installed. Plan to inspect the
filter periodically. A clogged air filter will increase operating
costs and shorten the life of the unit.
• Supply-air and return-air registers should not be
blocked. Drapes, furniture, and toys are some of the items
commonly found obstructing grilles. Restricted airflow less¬
ens the unit's efficiency and life span.
• The outdoor unit must have unrestricted 2 drflow. Do not
cover the unit, lean anything against it, or stand upon it. Do
not allow grass clippings, leaves, or other debris to accumu¬
late around or on top of the unit. Maintain a twelve-in. mini¬
mum clearance between the outdoor unit and tall grass,
vines, shrubs, et cetera.
• Your multipurpose indoor thermostat is the control cen¬
ter for your heat pump system. You should familiarize your¬
self with its proper operation. Attempting to control the
system by other means—for instance, switching the electri¬
cal supply power ON and OFF—may cause damage to the
unit.
• Thermostat “jiggling" causes rapid-cycling, which is
potentially damaging to the compressor. Do not move the
temperature selector on the thermostat for any reason for at
least 5 minutes after the compressor has shut off.
• During the heating season, never increase the indoor
thermostat setting more than one or two-degree increments.
If larger adjustments are made, the supplementary heating
source will be turned on automatically. Needless use of the
supplementary heat reduces potential energy savings.
• You may find that you can maintain greater personal
comfort by running the fan continuously. “Air pockets” can
form due to the structure of the house, placement of regis¬
ters, et cetera. These air pockets may be too cool or warm
for your liking. Continuous fan operation minimizes any
temperature differences. Also, systems equipped with elec¬
tronic air cleaners and/or humidifiers offer the added bene¬
fits of having the air continuously cleaned year-round, and
humidified during the winter season.
• Your heat pump will remove humidity from your home
during the cooling season. After a few minutes of operation,
you should be able to see water trickle from the condensate
drain of the cooling coil. Check this occasionally to be sure
the drain system is not clogged. Of course, don't expect to
see much drainage if you live in a very dry environment.
• During the heating cycle, air from your registers may
seem cooler than you might first expect. This is because the
air is being delivered at a higher velocity and a more con¬
stant flow than air supplied by a conventional furnace. Also,
your heat pump supplies air at 85 to 90 degrees Fahrenheit
instead of in sudden bursts of hot air as with a conventional
furnace. The air may feel cool because it is slightly less than
your body temperature. However, it is sufficiently warm to
keep you comfortable.
• Ice or frost will tend to form on the outdoor coil during
the winter heating operation. Your heat pump is designed to
automatically melt the ice. When in this defrost cycle, it is
