Piping Insulation
Refrigerant, chilled water and condensate pipes should be
insulated right up to the unit chassis to prevent condensation
which can damage the ceiling and objects located below the
piping. Chilled water valves must also be insulated to prevent
sweating.

Wiring

WARNING
1. Disconnect power supply before making wiring connections
or working on this equipment. Follow all applicable safety
procedures to prevent accidental power up. Failure to do
so can result in injury or death from electrical shock or
moving parts and may cause equipment damage.
2. All appliances must be wired strictly in accordance with
the wiring diagram furnished with the appliance. Any wiring
different from the wiring diagram could result in a hazard to
persons and property.
3. Any original factory wiring that requires replacement must
be replaced with wiring material having a temperature
rating of at least 221°F (105°C).
4. Ensure that the supply voltage to the appliance, as
indicated on the serial plate, is not 5% greater than rated
voltage.
AVERTISSEMENT
1. Débranchez l'alimentation électrique avant d'effectuer
des connexions ou de travailler sur l'appareil. Respectez
toutes les procédures de sécurité qui s'appliquent pour
éviter toute mise en marche accidentelle. Le non-respect
de cette directive peut entraîner des blessures ou la mort
causées par un choc électrique ou des pièces mobiles, en
plus d'endommager l'appareil.
2. Tous les appareils doivent être branchés de manière
strictement conforme au diagramme fourni. Tout câblage
différent de celui du schéma peut créer des risques de
dommages matériels ou de blessures.
3. Tout câblage usine d'origine exigeant un remplacement
doit être remplacé par un câble d'indice thermique nominal
de 221 °F (105 °C).
4. Assurez-vous que la tension d'alimentation de l'appareil,
comme indiqué sur la plaque de série, n'est pas de 5 %
supérieure à la tension nominale.

CAUTION
1. Ensure that the supply voltage to the appliance, as
indicated on the serial plate, is not 5% less than the rated
voltage.
2. 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.
ATTENTION
1. 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.
2. 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.
1. Installation of wiring must conform with local building
codes, or in the absence of local codes, with the National
Electric Code ANSI/NFPA 70 – Latest Edition. Unit must
be electrically grounded in conformance to this code. In
Canada, wiring must comply with CSA C22.1, Electrical
Code.
2. Electric wiring must be sized to carry the full load amp draw
of the motor, starter and any controls that are used with the
unit.
3. This equipment in its standard form is designed for an
electrical supply of 208-230V, 1Ph, 60Hz. When connection
to a 115V, 1Ph, 60Hz supply is necessary, a factory
mounted step up transformer must be fitted to the unit.
4. Any damage to or failure of units caused by incorrect wiring
of the units is not covered by warranty.
5. Once the refrigeration pipe work is complete, the electrical
supply can be connected by routing the cable through
the appropriate knockout on the side of the control panel.
Connect the supply and ground cables to the unit's power
terminals. Low voltage control wiring can be run through
alternate knockouts, provided in the side of the control
panel.
Note:


DX or Heat Pump units (Model Digit 3=D or H) with
electro-mechanical controls (Model Digit 8=E), a
thermostat with compressor on/off minimum time
protection is required.
