MODEL NUMBER NOMENCLATURE AND
DIMENSIONS
See Fig. 1 for 48FC model number nomenclature. See
Fig. 2 for unit dimensional drawings. Figure 2 shows service
clearance dimensions.
WARNING
Failure to follow this warning could result in personal
injury or death.
Disconnect gas piping from unit when leak testing at pres-
sure greater than 0.5 psig (3450 Pa). Pressures greater than
0.5 psig (3450 Pa) will cause gas valve damage resulting in
hazardous condition. If gas valve is subjected to pressure
greater than 0.5 psig (3450 Pa), it must be replaced before
use. When pressure testing field-supplied gas piping at
pressures of 0.5 psig (3450 Pa) or less, a unit connected to
such piping must be isolated by closing the manual gas
valve.
WARNING
Failure to follow this warning could cause personal injury,
death and/or equipment damage.
Puron
®
(R-410A) refrigerant systems operate at higher
pressures than standard R-22 systems. Do not use R-22 ser-
vice equipment or components on Puron refrigerant equip-
ment.
WARNING
Failure to follow this warning could cause personal injury
or death.
Relieve pressure and recover all refrigerant before system
repair or final unit disposal. Wear safety glasses and gloves
when handling refrigerants. Keep torches and other igni-
tion sources away from refrigerants and oils.
CAUTION
Failure to follow this caution may result in personal injury.
Sheet metal parts may have sharp edges or burrs. Use care
and wear appropriate protective clothing, safety glasses and
gloves when handling parts and servicing air conditioning
equipment.
WARNING
CARBON-MONOXIDE POISONING HAZARD
Failure to follow instructions could result in severe person-
al injury or death due to carbon-monoxide poisoning, if
combustion products infiltrate into the building.
Check that all openings in the outside wall around the vent
(and air intake) pipe(s) are sealed to prevent infiltration of
combustion products into the building.
Check that furnace vent (and air intake) terminal(s) are not
obstructed in any way during all seasons.
AVERTISSEMENT
RISQUE D’INTOXICATION AU MONOXYDE DE
CARBONE
Si ces directives ne sont pas suivies, cela peut entraîner des
blessures graves ou une intoxication au monoxyde de car-
bone pouvant causer la mort, si des produits de combustion
s’infiltrent dans le bâtiment.
Vérifier que toutes les ouvertures pratiquées dans le mur
extérieur autour du ou des tuyaux d’évent (et de la prise
d’air) sont scellées de manière à empêcher l’infiltration de
produits de combustion dans le bâtiment.
Veiller à ce que la ou les sorties de l’évent de l’appareil de
chauffage (et la prise d’air) ne soient, en aucune façon, ob-
struées, quelle que soit la saison.
