WARNING! Risk of improper wire sizing/rating and loose electrical connections causing overheated wire and
electrical connection terminals resulting in smoke or fire. Can cause serious injury or death. Building and
equipment damage may also result. Use correctly sized copper wire only and verify that all electrical
connections are tight before turning power On. Check all electrical connections periodically and tighten as
necessary.
WARNING! Risk of improper moving. Can cause serious injury or death. Building and equipment damage may
also result. Use only lifting equipment that is rated for the unit weight by an OSHA-certified rating
organization. The center of gravity varies depending on the unit size and selected options. The slings must
be equally spaced on either side of the center of gravity indicator. Shipping weights and unit weights are
specified in the Application and Planning Guide. Use the center of gravity indicators on the unit to determine
the position of the slings.
CAUTION: Risk of contact with extremely hot or cold surfaces. Can cause injury. Verify that all components
have reached a temperature that is safe for human contact or wear appropriate, OSHA-approved PPE before
working with the electric connection enclosures or unit cabinet. Perform maintenance only when the system
is de-energized and component temperatures have become safe for human contact.
CAUTION: Risk of contact with sharp edges, splinters and exposed fasteners. Can cause injury. Only properly
trained and qualified personnel wearing appropriate, OSHA-approved PPE should attempt to move, lift,
remove packaging from or prepare the unit for installation.
CAUTION: Risk of improper handling heavy and lengthy parts. Can cause injury. Building and equipment
damage may also result. Cabinet panels can exceed 5 ft. (1.5 m) in length and weigh more than 35 lb (15.9 kg).
Follow relevant OSHA lifting recommendations and consider using a two-person lift for safe and comfortable
removal and installation of cabinet panels. Only properly trained and qualified personnel wearing appropriate,
OSHA-approved PPE should attempt to remove or install cabinet panels.
CAUTION: Risk of improper piping installation, leak checking, fluid chemistry and fluid maintenance. Can
cause injury. Building and equipment damage may also result. Installation and service of this equipment
should be done only by qualified personnel who have been specially-trained in the installation of air-
conditioning equipment and who are wearing appropriate, OSHA-approved PPE.
CAUTION: Risk of improper power supply connection. Can cause equipment damage and loss of warranty
coverage. Prior to connecting any equipment to a main or alternate power source (for example back-up
generator systems) for start-up, commissioning, testing, or normal operation, ensure that these sources are
correctly adjusted to the nameplate voltage and frequency of all equipment to be connected. Also, ensure
that no three-phase sources are single-phased at any time. See transformer label for primary tap connections.
Installer will need to change transformer primary taps if applied unit voltage is other than pre-wired tap
voltage.
