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.
WARNING! Risk of top heavy unit falling over. Improper handling can cause equipment damage, injury or
death. Read all of the following instructions and verify that all lifting and moving equipment is rated for the
weight of the unit before attempting to move, lift, remove packaging from or prepare the unit for installation.
WARNING! Risk of wiring damage, short circuits and electric shock. Can cause overheated wiring, smoke, fire,
activation of fire suppression systems and EMS personnel and equipment, building and equipment damage,
injury or death. Insert CSA certified or UL listed bushings into holes and or knockouts used to route wiring
through metal panels to protect the wire insulation from contact with sheet metal edges.
CAUTION: Risk of explosive discharge of high pressure refrigerant. Can cause serious injury. Neutral and
service ports on the rotalock valve do not have a valve core. Front seat the service valves and relieve pressure
from the compressor before loosening a part or a component attached to the service valve. Follow local codes
to properly reclaim refrigerant.
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 contact with hot surfaces. Can cause injury. The compressor, refrigerant discharge lines,
fan motor, and some electrical components are extremely hot during unit operation. Allow sufficient time for
them to cool to a touch safe temperature before working within the unit cabinet. Use extreme caution and
wear appropriate, OSHA-approved PPE when working on or near hot components.
CAUTION: Risk of handling heavy and lengthy parts. Can cause personal injury and equipment damage.
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 exposure to harmful noise levels. Can cause hearing injury or loss. Depending on the
installation and operating conditions, a sound pressure level greater than 70 dB(A) may arise. Take
appropriate technical safety measures. Operating personnel must wear appropriate, OSHA-approved PPE
and observe all appropriate hearing protection safety requirements.
