Safety Summary
The following statements are general guidelines
followed by warnings and cautions applicable
throughout the manual.
Prior to performing any installation, operation, mainte-
nance or troubleshooting procedure, read and under-
stand all instructions, recommendations and guide-
lines contained within this manual.
All maintenance and/or repairs must be performed by
a journeyman, refrigeration mechanic or an air
conditioning technician.
Never operate the unit with any cover, guard, screen,
panel, etc., removed unless the instructions specifi-
cally state otherwise, then do so with extreme caution
to avoid personal injury.
Never lift any component in excess of 35 pounds
without help. If a lifting device is used to move a unit,
ensure it is capable of supporting the unit.
When working on electrical equipment, remove all
jewelry, watches, rings, etc.
Always disconnect the main power supply to the
equipment at the main power disconnect switch before
beginning work on the equipment. A lock-out tag-out
procedure should be followed to ensure that power is
not inadvertently reconnected.
Equipment may contain components subject to
Electrostatic Discharge (ESD). Before attempting to
mount or service these electronic devices, ensure
you have no charge built up by touching a ground
source. When possible, use a wrist-grounding strap
when working on or near electronic devices.
Never work on electrical equipment unless another
person who is familiar with the operation and hazards
of the equipment and competent in administering first
aid is nearby.
All personnel working on or near equipment should be
familiar with hazards associated with electrical
maintenance. Safety placards/stickers have been
placed on the unit to call attention to all personal and
equipment damage hazard areas.
Certain maintenance or cleaning procedures may call
for the use and handling of chemicals, solvents, or
cleansers. Always refer to the manufacturer's Material
Safety Data Sheet (MSDS) prior to using these
materials. Clean parts in a well-ventilated area. Avoid
inhalation of solvent fumes and prolonged exposure
of skin to cleaning solvents. Wash exposed skin
thoroughly after contact with solvents.
CAUTION
When the air conditioner is in the cooling mode,
the return air-intake and discharge (supply)
must be free of obstructions. Ensure panels are
secure and latched into position.
CAUTION
Do not use cleaning solvents near open flame or
excessive heat. Wear eye protection when blow-
ing solvent from parts. The pressure-wash should
not exceed 30 psig. Solvent solutions should be
disposed of in accordance with local and state
regulatory statutes.
CAUTION
The unit must be kept level and vertical in its
normal installed position.
