Carrier 58B - Manual (Page 2)

STOPPING YOUR UNIT - Follow these simple
procedures to put your unit into “retirement” for
the summer.
1. Close the main burner manual gas shutoff valve.
2. Close the pilot manual gas shutoff valve.
3. Turn the unit electric switch to “Off.”
4. Close humidifier water supply valve (if unit is
equipped with a humidifier).
MAINTAINING YOUR UNIT - The life of your
system depends on the care you give it. Proper care
assures good performance; lack of it can damage
the unit (and invalidate your warranty).
Here are the things you should do, or have your
dealer serviceman do for you.
NOTE: Before you start, turn off all electrical
power to unit and turn thermostat to “Off. ”
Keeping Filters Clean — As a homeowner, this is
your most important responsibility. A dirty filter
reduces efficiency of your system, causing erratic
performance of controls and resulting in damage to
the motor or heating element.
1. Inspect filters at regular intervals depending
upon dirt conditions. On new homes, check the
filter every week for four consecutive weeks to
begin with. In all cases, inspect your filters at
least every two or three weeks when the system
is in constant operation. Replace filters at the
beginning of each season — and thereafter as
needed.
2. If you have disposable-type filters and they are
moderately dirty, clean with vacuum or tap
lightly over newspaper. Replace filter with
arrows pointing in the direction of air flow.
(Turn dirtiest side toward return air stream to
prevent dirt from being blown into supply air
when the blower is started.) Replace disposable
filters with same type after one cleaning.
3. If you have permanent-type filters and they
become extremely dirty, they can be cleaned
with hose and water. Be sure to spray expand­
able aluminum-type filters with a filter coat
after each washing. Your dealer has this avail­
able in handy spray cans. If your filter is a
Duralast type, this coating is not necessary.
(Ensure that filters are thoroughly dry before
replacing them.) Some permanent-type filters
may be vacuum cleaned or shaken out. It’s not
necessary to wash them. Check the manu­
facturer’s recommendations.
NOTE: Do not operate unit with blower door
remo ved.
Lubricating Motors — Direct drive motor and
blower assemblies are factory lubricated and sel­
dom requite oiling. Frequency and amount of
oiling depends upon usage and climatic conditions.
Consult your dealer serviceman for specific in­
structions. Belt drive motor and blower assemblies
should be oiled at the beginning of each season
with a good grade of non-detergent SAE No. 20
motor oil. Oil cups are at each end of the motor.
NOTE: Do not overoil motor. Three drops in
each oil cup is enough. (More will attract dirt.)
Keeping Heater Element Clean — In your general
furnace housekeeping, don’t forget the heater
element. It’s a good idea to have your dealer
serviceman check the heat exchanger at the start of
each heating season, and if necessary perform the
following procedures.
1. Make sure that all utilities are turned off.
2. Remove burners, manifold assembly, vent con­
nectors, and draft diverter.
3. Remove flue baffles from upper flue outlet.
4. Clean flue ways with brush or vacuum cleaner.
5. Replace baffles, ensuring rear of baffle engages
dimple in heating element. Secure screws care­
fully so that heating element will be leak tight.
6. Replace remaining parts; turn on utilities.
7. Test for leaks.
Here's A Handy Checklist
If your furnace fails to operate properly, first
check the following. It may save you the cost of a
service call.
1. Is your room thermostat set correctly? On
heating/cooling systems, the thermostat system
switch should be turned to “Heat;” the fan
switch to “Auto.” or “Cont” (continuous fan
operation).
2. Are the power and gas both on?
3. Are the filters clean?
If the answer to these questions is “Yes,” and
the furnace still doesn’t operate properly, call your
Authorized Carrier Dealer for service.
