SPECIAL PRECAUTIONS
CAUTION
1. Do not overcharge the refrigeration system. This can lead
to elevated compressor discharge pressure and possibly
flooding to the compressor with liquid.
2. Units not approved for use in potable water systems.
3. Hot water supplied to the hot water heating option must not
exceed 200ºF (93°C) temperature or 125 PSIG (862 kPa)
pressure.
4. Ensure that the supply voltage to the appliance, as
indicated on the serial plate, is not 5% less than the rated
voltage.
5. In order to avoid a hazard due to inadvertent resetting of
the thermal cut-out, this appliance must not be supplied
through an external switching device, such as a timer, or
connected to a circuit that is regularly switched on and off
by the utility.
6. Do not attempt to reuse any mechanical or electrical
component which has been wet. Such component must be
replaced.
7. When servicing the unit, some components may be hot
enough to cause pain or injury. Allow time for cooling of hot
components before servicing.
ATTENTION
1. Ne surchargez pas le système de réfrigération. Cela
peut entraîner une pression d'évacuation élevée du
compresseur et possiblement son inondation.
2. Ces unités ne sont pas approuvées pour l'usage dans des
systèmes à eau potable.
3. La température de l'eau chaude alimentée en vertu de
l'option de chauffage de l'eau chaude ne doit pas dépasser
200 °F (93 °C) ou une pression de 125 lb/po² (862 kPa).
4. Vérifiez que la tension d'alimentation de l'appareil n'est pas
inférieure de plus de 5 % à la tension nominale inscrite sur
la plaque de série.
5. Afin d'éviter tout danger causé par la réinitialisation
involontaire du coupe-circuit thermique, cet appareil ne
doit pas être alimenté par l'entremise d'un dispositif de
commutation externe, comme une minuterie, ou relié à un
circuit qui est régulièrement mis en marche et coupé par le
service public.
6. Ne tentez pas de réutiliser un composant mécanique ou
électrique qui a été mouillé. Ces composants doivent être
remplacés.
7. Durant l'entretien de l'unité, certains composants peuvent
être assez chauds pour causer de la douleur ou une
blessure. Laissez les composants chauds se refroidir avant
de procéder à tout entretien.

IMPORT ANT
1. Unit Performance will be significantly reduced at or above
7215 ft (2200 m) and should not be operated above this
altitude.
2. For ceiling mounted units, check that the ceiling is capable
of supporting the weight of the unit. If used within a ceiling
grid, the ceiling grid is to be supported separately from the
unit.
3. Units with DX evaporator coils (refer to model
nomenclature) contain the refrigerant R-410A. Review the
R-410A Material Safety Data Sheet (MSDS) for hazards
and first aid measures.
4. Refrigerant charging should only be carried out by an EPA-
certified air conditioning contractor.
5. Units with DX coils (refer to the model nomenclature) are
partial units, complying with partial unit requirements of UL
60335-2-40, and must only be connected to other units that
have been confirmed as complying to corresponding partial
unit requirements of UL 60335-2-40/CSA C22.2 No. 60335-
2-40, or UL 1995/CSA C22.2 No. 236.
6. No water-flow can cause a freeze condition resulting in
damage to the coil.
7. Never leave the unit filled with water in a building without
heat unless antifreeze has been added.
8. Start up and adjustment procedures, installation, and
service of these appliances must be performed by a
qualified installation and service agency.
9. All refrigeration checks must be made by a qualified
R-410A refrigeration technician.
10. Do not release refrigerant to the atmosphere. When adding
or removing refrigerant, all national, state/province and
local laws must be followed
11. To check most of the Possible Remedies in the
Troubleshooting guide listed in Table 36.1, refer to the
applicable sections of the manual.
