Waste Outlet (Drip Pipe) Description and Location
These cases are equipped with a 1-1/2” PVC waste outlet connection that terminates in the center of the display case
below the insulated bottom. The water seal trap, elbow and cap are shipped loose for field installation.
NOTE: Improperly installed drain piping can seriously affect the operation of the case and result in increased main-
tenance cost and operation issues. Listed below are some general rules for drain piping installation.
• Never use a double water seal.
•
Never use a pipe size smaller than the pipe size or water seal size supplied with the case.
•
Always provide as much downslope as possible in drain piping. (1” fall for each 4’ of horizontal run)
•
Avoid long runs in drain piping which make it impossible to provide maximum downslope in piping.
•
Provide a space between the end of the drip pipe and the floor drain or sewer connection.
Case Freezing
Do not allow drain piping to come into contact with uninsulated suction lines that will cause drain water inside the
drain piping to freeze.
Drain Strainer
NOTE: Not all Kysor Warren cases have drain strainers. Drain strainers are optional. This information applies only to
cases equipped with drain strainers. The drain strainer is used to keep debris or foreign objects from entering the PVC
drain, which could cause blockage. To install, insert into the drain until the drain strainer stops. It will not be flush with
the top of the drain bushing. The strainer will extend above the hub by 1”. DO NOT flatten the drain strainer.
