WARNING
1. Improper installation, adjustment, alteration,
service or maintenance can cause property
damage, injury or death, and could cause
exposure to substances which have been
determined by various state agencies to cause
cancer, birth defects or other reproductive
harm. Read the installation, operating and
maintenance instructions thoroughly before
installing or servicing this equipment.
2. Units with DX evaporator coils (refer to
model nomenclature) contain R-410A high
pressure refrigerant. Hazards exist that could
result in personal injury or death. Installation,
maintenance, and service must only be
performed by an HVAC technician qualified
in R-410A refrigerant and using proper tools
and equipment. Due to much higher pressure
of R-410A refrigerant, DO NOT USE service
equipment or tools designed for refrigerants
other than R410A.
AVERTISSEMENT
1. Une installation, un réglage, une altération, une
réparation ou une maintenance impropre risque
de causer des dommages, des blessures ou
la mort, et d'engendrer une exposition à des
substances dont certains États ont déterminé
qu'elles étaient cancérogènes ou pouvaient
causer des malformations à la naissance et
des problèmes de reproduction. Lisez bien
les instructions d'installation, d'utilisation et de
maintenance avant d'installer ou de réparer cet
appareil.

AVERTISSEMENT
2. Les unités munies de serpentins évaporateurs
DX (reportez-vous à la nomenclature du
modèle) contiennent du fluide frigorigène à
haute pression R-410A. Des dangers existent
qui, s'ils se matérialisent, pourraient entraîner
des blessures ou la mort. L'installation,
l'entretien et le service ne doivent être effectués
que par un technicien de CVC qualifié quant à
l'usage du fluide frigorigène R-410A en utilisant
les outils et l'équipement appropriés. En raison
de la pression beaucoup plus élevée du fluide
frigorigène R-410A, N'utilisez PAS des outils
ou de l'équipement de service qui ne sont pas
conçus spécifiquement pour le R-410A.
IMPORTANT
1. The use of this manual is specifically intended
