guidelines being neglected, the repairs and parts replacements will not be covered
under warranty.
It is recommended that the customer contact the local Authorized Service Agent to
provide a quote to perform periodic Preventative Maintenance.
MONTHLY PM PROCEDURES
1. Cleaning of all condenser coils on a monthly basis. Condenser coils are a
critical component in the life of the compressor and must remain clean to
assure proper air flow and heat transfer. Failure to maintain this heat transfer
will affect unit performance and eventually destroy the compressor. Clean the
condenser coils with coil cleaner and/or a vacuum, cleaner and brush. NOTE:
Brush coil in direction of fins, normally vertically as to not damage or restrict
air from passing through condenser.
2. Inspect all silicone seams at interior of the rail and refrigerated base cabinet
on a monthly basis. Re-apply food grade silicone sealant as needed to any
seams where silicone has peeled away or cracked. Apply silicone to a clean
dry surface. Allow sufficient drying time to assure best adhesion of sealant.

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
