Installation
Drain Connections
• Drain lines must have a 1.5" drop per
5 feet of run, and must not create traps.
• The floor drain must be large enough to
accommodate drainage from all drains.
• Run separate bin and ice machine
drain lines. Insulate them to prevent
condensation.
• Vent the bin and ice machine drain
to the atmosphere. The ice machine
drain requires an 18" vent. Do not vent
the condenser drain on water‑cooled
models.

Auxiliary Base Drain Installation
• An auxiliary drain is located in the ice
machine base to remove moisture in
high humidity areas.
• SF3000C requires base drain connection:
1" (25 mm) NPT.
• View the back of the ice machine base
on the compressor side and locate and
remove the cap plug.
• Route tubing to an open site drain:
1.
Use 0.75" (19 mm) CPVC tubing.
2.
Apply a bead of silicone around the
exterior of the ice machine tubing
and insert into ice machine base. The
silicone will secure the tubing and
provide a watertight seal.
3.
Provide support for tubing.
Air Gap
A greater than 1 inch (25 mm) air gap is
built into the ice machine for back‑flow
prevention. This air gap exceeds NSF 12,
AS/NZS 3500.1 and AS/NZS 3500.2
requirements for back‑flow prevention.
INSTALLATION NOTE (SWITZERLAND)
The connection to the drinking water
network must be made with a certified
back flow preventer type EA (EN13959)
and with a certified connection hose
(EN13618 or EN61770) on site.
