MODEL NUMBER NOMENCLATURE AND
DIMENSIONS
See Fig. 1 for 48JC model number nomenclature. See Fig. 2 (on
pages 4 - 6) for unit dimensional drawings and service clearance
dimensions.
WARNING
FIRE, EXPLOSION HAZARD
Failure to follow this warning could result in death, serious
personal injury and/or property damage.
Disconnect gas piping from unit when pressure testing at
pressure greater than 0.5 psig (3450 Pa). Pressures greater than
0.5 psig will cause gas valve damage resulting in hazardous
condition. If gas valve is subjected to pressure greater than
0.5 psig, it must be replaced before use. When pressure testing
field-supplied gas piping at pressures of 0.5 psig or less, a unit
connected to such piping must be isolated by closing the
manual gas valve(s).
WARNING
UNIT OPERATION AND SAFETY HAZARD
Failure to follow this warning could cause personal injury,
death and/or equipment damage.
R-410A refrigerant systems operate at higher pressures than
standard R-22 systems. Do not use R-22 service equipment or
components on R-410A refrigerant equipment.
WARNING
PERSONAL INJURY AND ENVIRONMENTAL
HAZARD
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 ignition sources away from refriger -
ants and oils.
CAUTION
PERSONAL INJURY HAZARD
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.
