GRAVITY DRAIN INSTALLATION

Plumbing installation must observe all state and local codes.
These guidelines must be followed when installing drain lines to prevent water from flowing back into the
ice maker storage bin and potentially flowing onto the floor causing water damage:
• Drain lines and fittings must have a 5/8" inside diameter.
• Drain lines must have a 1" drop per 48" of run (1/4" per foot) and must not create traps.
• The floor drain must be large enough to accommodate drainage from all drains.
• Insulate the bin drain line to prevent condensation.
Be sure to follow these guidelines to prevent water backing up into the storage bin.
Below are examples of gravity drain line installations. If a trap is in the drain line, the drain line must be
vented to ensure proper draining. Without the vent, water will backup until enough pressure builds up to
force the water past the trap. Water may backup into the ice bin before the amount of pressure needed is
achieved. Water in the storage bin will cause the ice in the bin to melt prematurely.
The customer's complaint will be slow ice production. The ice that has been made is melting
prematurely because water is backing up in the ice bin.
