The numbers above represent boiling points for R-134a.
EVAPORATOR
pressures represent gas temperatures
inside the coil and not the coil
surfaces. Add to temperature for coil
air-off temperatures (8 - 10f.)
CONDENSER
temperatures are not ambient
temperatures. Add to ambient
(35 - 40 F.) for proper heat transfer,
then refer to pressure chart.
Example:
90 F. ambient temp.
Conditions will vary for different system configurations.

CHECKING/ADDING REFRIGERANT
Allow only certified personnel to service the heater/air conditioner system. The chart below shows relative
temperatures and pressures for the system.
Generally, for most Barko machines, 3 pounds of refrigerant is required for the system to operate properly. However,
use the chart below to determine the exact amount.
WARNING
Older air conditioning equipment may contain R-12, a substance which harms public
health and environment by destroying ozone in the upper atmosphere. To remove R-12
from the air conditioning system, use service equipment certified to meet the requirements
of S.A.E. J2209 or J1990.
