How the dispenser works
Follett's U155 Series ice dispensers are available in manual load configurations (using ice from another source)
or automatic load configurations, fed from one or two Follett 400 lb (181kg)/day remote icemakers.
In all models, ice is stored below the counter in the dispenser storage area. When the dispense lever or button is
pushed, the dispense motor is activated. This causes the wheel assembly in the storage area to turn, moving ice
to the vertical auger assembly, which carries ice up to the dispense chute where it drops by gravity into the
container.
In automatic load units, ice is manufactured in either one or two Follett remote icemakers. These icemakers may
be located up to 20 f. (6m) away from the dispenser. As water freezes to the inside walls of the icemaker
evaporator, a rotating stainless steel auger removes ice and carries it to the top of the evaporator assembly
where it is compressed and extruded through an outlet port. The extruded ice is then pushed through the tube to
the storage compartment of the dispenser. A level fill circuit maximizes fill in the storage area by rotating the
wheel at intervals until the bin is completely filled. When the bin is filled, a bin stat shuts the icemaker off to avoid
overfilling of the bin. The icemaker will restart after 20 minutes if the bin is calling for ice.
Units with integral ice-water bath beverage cooling are equipped with a water bath timer circuit that activates the
water bath pump for 35 minutes when ice lever or button is activated, or when the ice water bath periodically calls
for more ice.
Cleaning
Using solutions below, clean and sanitize storage area and beverage lines before starting up unit and on a
routine basis as noted below.
Solution A: Prepare a cleaning solution (200 ppm of available chlorine content) of Ecolab Mikro-chlor
Cleaner or equal chlorinated detergent. Cleaning solution temperature must be at
75˚ – 125˚F (24˚ to 52˚C).
Solution B: Prepare a sanitizing solution (50 ppm of available chlorine content) of Ecolab Mikro-chlor
Cleaner or equal chlorinated detergent. Sanitizing solution temperature must be at
75˚ – 125˚F (24˚ to 52˚C).
Cleaning bin before use
1. Wipe storage area with Solution A.
2. Rinse thoroughly with clear, potable water.
3. Wipe with Solution B to sanitize.
Warning: Always disconnect power before cleaning dispenser. !
