Page 7: Installation
SERVICE MANUAL 2. INSTALLATION 2.1.- PLACING OF THE ICE MAKER This ice maker is not designed for outdoor operation. The icemaker should not be located next to ovens, grills or other high heat producing equipment. The FDHD machines are designed to operate at room temperature between 10ºC and 43ºC . There may be some difficulties in ice slab removal under the minimum temperatures. -

If the drain pipe runs incorrectly, the pump may not be able to drain the water, because the flow of the pump may be influenced due to the existence of stored air within the circuit.

SERVICE MANUAL 4. SEQUENCE OF OPERATION UNDERCOUNTER MODELS (NG) Once you connect the machine there is a time delay of 2 minutes during which the water valve is activated to ensure the water tray is filled. Once the time is up, the compressor starts and the pump which recirculates the water from the water tray to the upper distributor which provides a soft and uniform flow of water over the evaporator cells, in which the water starts freezing. - Page 15 SERVICE MANUAL PCB connections Outputs compressor Water pump Water inlet valve GC Hot gas valve.

SERVICE MANUAL 5. SEQUENCE OF OPERATION -MODULAR MODELS (MS) Initial Start-up: The pump and the drain electro valve are energized during 30 seconds to empty the water tray preventing the scale build-up in water. Then the pump and the drain electro valve 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. - Page 22 SERVICE MANUAL Production Following outputs are activated: - Compressor (C). - Pump (B). It is activated with delay time t11. - Water inlet valve (EW). It is kept active during time t8, beginning with the start of B. This phase is maintained until the thickness detection sensor gives a signal (which is maintained during time t2).

Page 28: Maintenance And Cleaning Procedures
SERVICE MANUAL 7 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 dissolves 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. - Page 29 SERVICE MANUAL c) Remove the back metal lid and the top panel (if it need be to make easier the cleaning operations). d) 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. Pipe drain e) Prepare a solution of an appropriate product for the cleaning of ice machines (lime).
- Page 30 SERVICE MANUAL h) Disconnect power. i) Remove the auxiliary pipe to drain and purge out the ice machine scale remover and residue. Replace it. j) Mix enough cleaning solution (as in point e) to clean parts and interior food zone surfaces. k) Remove curtain.
- Page 31 SERVICE MANUAL o) Sanitize all surfaces of the shield applying liberally the sanitizer solution using a cloth or sponge. p) Sanitize all the interior surfaces of the freezing compartment (including the storage bin) applying liberally sanitizer solution, using a cloth or sponge. q) Return shield to its position.
- Page 32 SERVICE MANUAL Front panel 3) Prepare a solution of an appropriate product for the cleaning of ice machines (lime). Do not use hydrochloric acid. We recommend the use of any NSF approved scale removal product. In modular machines the water bucket is filled automatically so we recommend to prepare a previous solution To start a cleaning cycle, move the ice-wash switch to the WASH position (position II).
- Page 33 SERVICE MANUAL MS 400- 22 4) Allow the solution to circulate in the water system for 30-40 minutes and then set the ice- wash switch to the OFF position. 5) To purge out the ice machine scale remover and residue move the ice-wash switch to the WASH (the machine will drain the reservoir and refill it) and then set the ice-wash switch to the OFF position.
- Page 34 SERVICE MANUAL 10) Clean the interior surfaces of the freezing compartment (including walls, plastic parts of the evaporator, distributor...) and the front panel with the cleaner solution using a brush or cloth. 11) Mix a solution of sanitizer using approved sodium hypochlorite food equipment sanitizer to form a solution with 100 to 200 ppm free chlorine yield.
