3.- Sequence of Operation
•
Initial Start-up: The first time the machine is started there is a delay of 30" in the power on sequence, it begins with the harvest
sequence to ensure the water tray is filled. Before the compressor starts, there is a pressure relief to ensure a soft start-up.
•
Freeze sequence: The compressor is energized. The freezing time is a programmed time, can be adjusted following the
previous table. The water circulates from the water tray to the upper distributor, flowing through each cube cell, where it freezes.
•
Harvest sequence: The hot gas valve is opened and at the same time energizes the water inlet valve during a certain time to fill
the water tray with the appropriate quantity of water. The ice slab slides off the evaporator and falls into the bin. Curtain opening
finishes harvest step. After this, the freeze sequence starts again.
•
When storage bin is full, the ice slab cannot fall down and curtains remains opened. The machine shuts off until enough ice has
been removed from the storage bin and the curtain close again.
Maintenance and Cleaning Procedures
It is the User's responsibility to keep the ice machine and ice storage bin in a sanitary condition.
Ice machines also require occasional cleaning of their water systems with a specifically designed chemical. This chemical dissolve
mineral build up that forms during the ice making process.
Sanitize the ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and sanitized.
The ice machine's water system should be cleaned and sanitized at least twice a year.
CAUTION: Do not mix Ice Machine Cleaner and Sanitizer solutions together.
WARNING: Wear rubber gloves and safety goggles when handling Ice Machine Cleaner or Sanitizer.
WARNING: Unit should always be disconnected during maintenance/cleaning procedures.
CLEANING WATER DISTRIBUTION SYSTEM
(1) Cleaning Water Distribution System for Undercounter Models
1. Set the switch to the OFF position after ice falls from the evaporator at the end of a harvest cycle or set the switch to the OFF
position and allow the ice to melt off the evaporator.
CAUTION: Never use anything to force ice from the evaporator.
2. Remove the back metal lid and the top panel (if it need be to make easier the cleaning operations).
3. Remove all ice from the bin.
4. Remove the auxiliary pipe for drain operations near the pump and empty the water tray. Return it to their original position to
avoid water spill.
