Flammable refrigerant used.
CAUTION! – Handling, moving, and operating the refrigerator to avoid either damaging the refrigerant tubing or
increasing the risk of a leak.
§ If the equipment is not transported vertically, a period of at least 24 hours must be allowed before starting.
The equipment must be transported and handled exclusively in upright position. This is required to avoid
contamination of the refrigerant with compressor oil. Contamination could result in valve and heat exchanger coil
failure, problems starting the electric motor, or the risk of gas leak. The manufacturer is not responsible for any
problems due to transport executed in conditions other than those specified.
The equipment must be handled using a fork lift truck or a pallet truck with suitable forks (fork length at least equal
to 2/3 length of unit).
§ Read this manual thoroughly before operating, installing or performing maintenance on the equipment. Failure to follow
instructions in this manual can cause property damage, injury or death.
§ The machine contains R600a refrigerant. R600a (isobutane) is flammable.
§ When servicing the equipment, be sure to lock the circuit breaker, and display an in-service notice.
§ This equipment contains high-voltage electricity and refrigerant charge. Installation and repairs are to be performed by
properly trained technicians aware of the dangers of dealing with high voltage electricity and refrigerant under pressure. The
technician must also be certified in proper refrigerant handling and servicing procedures. All lockout and tag out procedures
must be followed when working on this equipment.
§ Repair on R600a systems must always be done in a well-ventilated area.
§ Because R600a is highly flammable, a combustible gas leak detector is required when servicing R600a systems.
§ Keep ventilation openings, in the appliance enclosure or in the built-in structure, clear of obstruction.
§ Do not use mechanical devices or other means to accelerate the defrosting process, other than those recommended by the
manufacturer.
§ Do not damage the refrigerant circuit.
§ Do not store explosive substances such as aerosol cans with a flammable propellant in this appliance.
§ Do not use electrical appliances inside the food storage compartments of the appliance, unless they are of the type
recommended by the manufacturer.
§ Only use parts recommended or provided by the manufacturer.
§ Do not tilt unit further than 30° off vertical during uncrating or installation.
§ If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in
order to avoid a hazard.
§ This appliance is designed for commercial use.
