Safety Summary
The following statements are general guidelines
followed by warnings and cautions applicable
throughout the manual.
Prior to performing any installation, operation,
maintenance or troubleshooting procedure read and
understand all instructions, recommendations and
guidelines 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
specifically 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.
WARNING
Refrigerant (R22 or R407C) is used with this
equipment. Death or serious injury may result if
personnel fail to observe proper safety precau-
tions. Great care must be exercised to prevent
contact of liquid refrigerant or refrigerant gas, dis-
charged under pressure, with any part of the
body. The extremely low temperature resulting
from the rapid expansion of liquid refrigerant or
pressurized gas can cause sudden and irrevers-
ible tissue damage.
As a minimum, all personnel should wear ther-
mal protective gloves and face-shield/goggles
when working with refrigerant. Application of
