Safety information
SAFETY INSTRUCTIONS
• Installation and maintenance must only be carried out
by qualied personnel who are familiar with this type of
equipment.
• Always wear safety glasses, gloves, and head protection
when working on the equipment.
• Avoid contact with sharp edges and exposed nned sur-
faces because these can cause painful lacerations.
• The equipment can be pressurized with dry air during
manufacturing.
• Properly evacuate all units before charging the system.
• Disconnect all power sources before carrying out any
service work on the units.
• Never apply heat to a sealed refrigeration system.
• Keep hands away from the fans when the unit is running.
• Ensure all mounting bolts are tight and are the correct
length for the specic application.
• Maintain all safety labels on the unit in good condition. If
required, replace with new labels.
• Check all eld wiring and be in strict conformity with the
equipment requirements and all applicable national and
local codes.
• Use the name plate electrical data for conductor and
fuse sizing.
REFRIGERANT SAFETY
WARNING
Although halocarbon refrigerants are classied as safe
refrigerants, certain precautions must be observed
when handling them. Refrigerant can be harmful if
inhaled. When released to the atmosphere in the liquid
state refrigerants evaporate rapidly, freezing anything
they contact. Refrigerants must be used and recovered
responsibly.
Failure to follow this warning may result in personal
injury or death.
WARNING
Failure to comply with any of these requirements could
result in serious damage to the equipment and/or the
property where it is installed, and personal injury and/
or death to themselves and/or people at the specic
location.
DANGER
Anhydrous Ammonia (NH
3
)
Specic precaution must be adhered to when people are
working with or are exposed to Anhydrous Ammonia.
Ammonia is considered a high health hazard because
it is corrosive to the skin, eyes, and lungs. Exposure
to 300 parts per million (ppm) is immediately danger-
ous to life and health. Ammonia is also ammable at
concentrations of approximately 15% to 28% by volume
in air. When mixed with lubricating oils, its ammable
concentration range is increased. It can explode if re-
leased in an enclosed space with a source of ignition
present, or if a vessel containing anhydrous ammonia
is exposed to re.
Personal protective equipment must be worn at all
times when working with Ammonia. For systems that
have an operating charge greater than 10,000 lb, a
process safety management program is mandatory.
More information on this topic is available from OSHA.
Failure to follow this warning may result in personal
injury or death.
General information
FRICK
®
evaporators and air coolers are designed to pro-
vide optimum efciency and an extended life when prop-
erly installed, operated, and maintained. The development
of a comprehensive maintenance schedule is suggested,
to be undertaken on a regular pre-determined basis. This
manual can assist the owner/operator in developing such a
schedule.
This equipment is relatively complicated and only suitable
individuals who are qualied to carry out these functions
can perform installation, operation, maintenance, and
servicing. These individuals must also be familiar with, and
comply with, all applicable governmental standards and
regulations pertaining to the functions.
The type of refrigerant and method of feed to the evapo-
rator must comply with what is indicated on the submittal
drawings and the unit’s nameplate.
Never exceed design operating pressures, as indicated on
the nameplate.
Evaporators and all piping systems must be correctly
evacuated before charging the system with refrigerant.
This ensures the complete removal of moisture and non–
condensables from the entire refrigerant circuit.
