2.- Start-Up
Once the installation instructions are followed (ventilation, site conditions, temperatures, water quality, etc.), proceed as follows:
1.
Open the water inlet. Verify the no existence of leakages.
2.
For undercounter models open the door and remove the protection elements on the shield. For modular models remove the two locking screws on top of
machine, take off the front panel and remove protection elements on the shield and on the thickness sensor.
3.
Verify that the shield moves freely. For modular models verify also the thickness sensor moves freely.
4.
Connect the machine to the power supply.
5.
For undercounter models: push the blue switch on the machine front side. For modular models: push the blue switch found on the back of the machine and then
set the ice-wash switch to the position I.
6.
Verify that there are no vibrations or frictions on the elements.
7.
Verify that the water fall to the evaporator is occurring uniformly and all ice cubes are properly watered.
8.
Close door (for undercounter models) / Replace the front panel in its place (for modular models).
9.
Verify that after the final cycle, the frost on the aspiration pipe is at 20 mm (0.78 in) of the compressor.
10.
For undercounter models adjust the cycle time.
Damages due to the lack of maintenance and cleaning operations are not included on the warranty.

Sequence of Operation
(4)
FOR UNDERCOUNTER MODELS:
(5)
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.
(6)
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.
(7)
Harvest sequence: The hot gas valve is opened during a certain time, programmed with the switches configuration from the previous table, 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 into
the bin. After this, the freeze sequence starts again.
(8)
When storage bin is full the stock thermostat detects a low temperature and the machine shuts off at the end of the freeze sequence. The ice machine remains
off until enough ice has been removed from the storage bin and the stock thermostat doesn’t detect this low temperature.
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).
