BEFOREYOU REQUEST A "SERVICE CALL"
BEFOREYOU CALL FOR SERVICE, CHECK FOR
THESE EASILY SOLVED PROBLEMS:
• Check the lnain power discomaect
switch. Verify that the circuit break-
ers are on and that fuses have not
blown. If you lnUStreset breakers or
replace filses, do so only once. Con-
tact your selwicing dealer for assis-
tance if the breakers trip or the filses
blow a second time.
• If the hulnidity level is too low, check the hulnidistat setting.
Confirln that the saddle valve is turned on. Check the evapora-
tor pad, and clean or replace the pad as necessary. Check water
level in Model HUMCCWTR.
• Check for sufficient airflow. Check the fimmce filter or elec-
mmic air cleaner for excessive accumulations of dirt. Check for
blocked return- or supply-air grilles. Be sure grilles are open
and unobstructed.
• If water drips froln the humidifier, check the drain hose for
kinks or obstructions. If your unit is a Model HUMCCWTR,
dripping may indicate that the float valve requires adjustlnent.
If your colnfort system still fhils to operate properly, contact
your selwicing dealer for troubleshooting and repairs. Specify
your apparent probleln, and state the lnodel and serial nulnbers
of your equiplnent. (You should have theln recorded where
noted in this booldet.) With this inforlnation, your dealer lnay be
able to offer helpfid suggestions over the phone, or save valuable
time through knowledgeable preparation for the selwice call.

Cleaning or replacelnent of the evaporator pad as required.
• A check of all electrical wiring and comaections.
• A check of water comaections to the unit.
• Operational check of the complete colnfort system to deter-
mine acttml worldng condition. Necessary repair and/or adjust-
lnent should be perforlned at this time.
