5. SEQUENCE OF OPERATION -MODULAR MODELS (MS)

Initial Start-up:

The pump and the drain electrovalve are energized during 30 seconds to empty

the water tray preventing the scale build-up in water. Then the pump and the drain electrovalve

are de-energized, and the water inlet valve is energized filling the water tray until the water level

sensor detects the water reaches the appropriate level. Then the freeze sequence starts.

Freeze sequence:

The compressor is energized and the water pump is energized after 30

seconds. The water inlet valve is also energized at the same time that the water pump to replenish

water level and then de-energized. The compressor and water pump will continue energized until

the thickness sensor detects the thickness of the ice slab is the appropriate. Then the harvest

sequence starts.

Harvest sequence:

The compressor will continue energized. The hot gas valve is energized

throughout the harvest phase to divert hot refrigerant gas into the evaporator. The water pump

and the drain electrovalve are energized during 45 seconds to empty the water tray and remove

mineral deposits. After this (water pump and drain electrovalve de-energized) the water inlet valve

is energized filling the water tray until the water level sensor detects water reaches the level. The

ice slab slides off the evaporator and into the bin. The momentary opening and re-closing of the

shield indicates the harvest sequence has finished and goes to the freeze sequence. If curtain

remains opened for more than 30" the machine switch to the status of full bin stand-by

5.1.- INITIAL START-UP

It is carried out at machine work start in following cases (being all outputs switched off):

- when machine is connected to power supply.

- when the switch is turned to the ICE position

- after a stop due to full storage

During start-up time t4 the pump (B) and the drain valve (EP) are activated.
Subsequently, B and EP are closed and the water inlet valve (EW) is opened until the level sensor
(NW) indicates that the storage reservoir is filled with water. At this point, the production phase
starts.
