2.4 Safety Precautions concerning the refrigerant
Fluorocarbon refrigerants are classified as safe refrigerants, however you must ob-
serve certain precautions during the installation process. When released to the at-
mosphere in the liquid state, fluorocarbon refrigerants evaporate rapidly. This fast
evaporation freezes anything in contact with the liquid refrigerant instantaneously. In
contact with parts of the human body, it can cause severe frostbites.
2.4.1 First Aid
General provisions in case of frostbite
In the event of frostbite, you should generally protect the affected area from further
injury, warm the affected area but do not apply heat and observe and maintain res-
piration.
Frostbite of the eyes:
In case of contact with liquid refrigerant, immediately flush eyes with large amounts
of water and get prompt medical attention.
Frostbite of the skin:
Flush the affected area with large amounts of lukewarm water for a long time. Do
not apply heat. Remove contaminated clothing and shoes. Loosely bandage frost-
bite burns with dry, sterile, sizeable dressing to protect from infection or injury. Get
medical attention without delay. Wash contaminated clothing before wearing it
again.
2.4.2 Environmental considerations
There is no need to handle refrigerants in the installation process. In case of servic-
ing, service personnel must be aware of federal regulations concerning the use of
refrigerants and the certification of technicians. For additional information on regula-
tions and technician certification programs, contact your local GOVI dealer or in-
quire [e-mail].
GOVI refrigeration units and are shipped with a suitable charge of refrigerant
R452A and R134a. The refrigerant shall not be vented into the atmosphere. There
is risk of severe injuries upon contact with eyes or skin.
In case of fluid leaking out of the refrigeration unit, do not continue with the installa-
tion process. Contact your GOVI dealer for assistance immediately. The fluid may
contain substances that need special provisions for a clean environment and may
cause injury on contact with skin.
Please read and understand the safety sheet for R452A and R134a with the pro-
ducer‘s description in chapter 9.2 Safety data sheet.

The refrigeration unit is intended for utilization in refrigerated trailers in which tem-
peratures from
10°F to 50°F (arktik 2000US)
32°F to 50°F (arktik 2500US)
10°F to 0°F (arktik 1500US/F) are required.
Operation is based on the cooling cycle principle in that heat transference is by
means of a refrigerant which absorbs heat in the evaporator and then releases this
in the condenser. All this takes place within a closed loop. The refrigerant is pres-
surized by an electrically driven compressor, fluidized in the condenser, atomized
by means of a throttle valve and evaporated in the evaporator. The evaporator is lo-
cated inside the trailer, the condenser on the outside.
The refrigeration unit is equipped with forced-ventilated condenser and evaporator
and fitted with axial fans; the unit has electronic temperature control.
The refrigeration unit consists of a self-supporting, powder coated, sheet metal
chassis and an ABS front cover.
