REFRIGERANT

The correct type of refrigerant will be stamped on each serial plate. The case refrigeration piping is factory sealed, pressurized and leak tested. Before making refrigeration hookups, depress universal line valve to ensure that coils have maintained pressure during shipment.

!WARNING

Refrigerant vapor is hazardous to your health and can cause death.

Avoid breathing refrigerant and lubrication vapor or mist. Exposure may irritate eyes, nose and throat. If accidental system dis- charge occurs,ventilate work area before resuming service.

Always wear safety goggles and protective gloves when working with refrigerants. Contact with refrigerant may cause injury. Disconnect hoses with extreme caution! All hoses may contain liquid refrigerant under pressure.

Be sure that any room where you are working is thoroughly ventilated, especially if a leak is suspected.

Read all safety information regarding the safe handling of refrigerant and refrigerant oil, including the Material Safety Data Sheet. MSDS sheets can be obtained from your refrigerant supplier.

Refrigeration lines are under pressure and should be depressurized before attempting to make any connections.

When brazing pipes, be sure to use the insulation blanket shipped with the merchandiser to prevent fire or damage to the plastic case bottom.

REFRIGERANT PIPING

Connection Location

The refrigerant line connections are at the right- hand end of the merchandiser (as viewed from the front) beneath the display pans. A sticker marks the location of the connection “pod.” The installer must saw a hole through the pod to exit the case.

After connections have been made, seal this outlet thoroughly. Seal both the inside and the outside. We recommend using an expanding polyurethane foam insulation.

Multiplexing

Piping of cases operating on the same refrigera- tion system may be run from case to case. DO

NOT RUN REFRIGERANT LINES THROUGH CASES

THAT ARE NOT ON THE SAME REFRIGERATION

SYSTEM BRANCH as this may result in poor refrigeration control and compressor failure.

Interconnecting piping inside the merchandiser must be located as shown below to allow room for lifting the hinged fan plenums and for clear- ance beneath the display pans. The intercon- necting piping may be run outside the case.
