charging the refrigerant system. Do not pressurize the system higher than the design pressure marked on the
unit's nameplate.
For systems requiring EU CE compliance (50 Hz), the system installer must provide and install a pressure relief
valve in the high side refrigerant circuit that is rated same as the refrigerant
high side “Max Allowable
Pressure” rating that is marked on the unit serial tag. Do n
ot install a shutoff valve between the compressor
and the field installed relief valve. The pressure relief valve must be CE-certified to the EU Pressure Equipment
Direct
ive by an EU “Notified Body.”
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. Use the center of gravity indicators on the unit
to determine the position of the slings.
WARNING! Risk of contact with high-speed rotating fan blades. Can cause serious injury or death. Open all
local and remote electric power-supply disconnect switches, verify with a voltmeter that power is off, and
verify that all fan blades have stopped rotating before working in the unit cabinet or on the fan assembly. If
control voltage is applied, the fan motor can restart without warning after a power failure.
WARNING! Risk of contact with extremely hot and/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 within 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.

WARNING! Risk of improper wire sizing/rating and loose electrical connections. Can cause overheated wire
and electrical connection terminals resulting in smoke, fire, equipment and building damage, injury or death.
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.
CAUTION: To ensure the safety, before welding the pipeline and patching welding, all nitrogen of air condition
system must be discharged to release the system pressure.
CAUTION: Risk of improper moving, lifting and handling. Can cause equipment damage or injury. Only
