This piece of equipment uses a R290 Refrigeration system. This equipment has
been clearly marked on the serial tag the type of refrigerant that is being used.
There is also a warning labels stating that the unit contains R290 refrigerant. R290
is safe to use as long as you follow these warning labels.
No smoking or open flames when servicing this equipment. If needed, use a CO2
or dry-powder type fire extinguisher.
Replacement parts used on any R290 Refrigeration system cabinet must have
specific UL certification for non-sparking components.
Only authorized service technician, certified in R290 system should service this
equipment.
MANIFOLD SET
A R134A manifold set can be used for servicing this equipment.
REFRIGERANT RECOVERY
Follow all national and local regulations for R-290 refrigerant recovery.
LEAKING CHECKING AND REPAIR
Leak check an R-290 system the same way you would an R-134a or R-404A
system with the following exceptions.
1. Do not use a Halid leak detector on a R290 system.
2. Electronic leak detector must be designated specifically for combustible gas.
Use of a bubble solution or an ultrasonic leak detector are acceptable.
When repairing a leak, it is recommended using oxygen free dry nitrogen with a
trace gas not exceeding 200PSI.
When accessing an R290 system, piercing valves are not to remain on the
equipment in a permanent manner. After charge is recovered, Schrader valves
are to be installed on the process stubs. Proper charge is to be weighed into the
system and the system is to be leak checked afterwards.
The R290 equipment must have red process tubes and other devices through
which the refrigerant is serviced, such as any service port. This color marking
must remain on the equipment. If marking is removed, it must be replace and
extend at least 2.5 centimeters (1”) from the compressor.
CHARGING
Follow the charge amount specified on the data tag. It is recommended to use the
shortest hoses possible to prevent undercharging.
• Ensure the system is sealed and leak checked
• Evacuate system to a minimum 500 micron
• Weigh in correct charge
• Leak check the system again
• Bleed the refrigerant from the high side hose to the low side hose
• Disconnect the hoses
• Remove line taps
