Ice-Tech SS 25 Guide

SS25 MAINTENANCE
1. AIR CONDENSER CLEANING:
Disconnect the unit from the electricity.
Clean condenser using a vacuum cleaner, soft brush or low pressure air. Clean
from top to bottom, not side to side. Be careful not to bend the condenser fins.
Connect the unit to the electricity.
2. WATER CONDENSER CLEANING:
Disconnect the unit from the electricity.
Closet the inlet water faucet.
Disconnect the condenser water inlet and outlet .
Prepare the cleaning product Calklin or a solution with 50% phosphoric acid
and distilled water. Do not use hydrochloric acid. We recommend using the
cleaning product Calklin. The mixture is more effective if the water is between
35ºC and 40ºC. Flow the solution through the condenser for about 10 minutes
using a recirculating pump.
Empty the product from the condenser and connect the condenser water intlet
and outlet.
Open the water faucet.
Connect the unit to the electricity.
3. WATER FILTER REPLACE
Disconnect the unit from the electricity.
Closet the inlet water faucet.
Close de faucets before and after the filter.
Remove the old cartridge and replace it with a new one.
Open all the closed faucets.
Connect the unit to the electricity.
4. WATER CIRCUIT CLEANING:
Switch off the the unit with the main switch.
Remove the top cover.
Place the overflow pipe. Remove the evaporator cover.
Prepare a solution of 50% phosphoric acid in distilled water. Do not use
hydrochlorate acid.
Pour slowly this solution in the upper part of the evaporator, until it overflows in
the water tray. The mixture is more effective with the water between 35ºC. and
40ºC.
Let solution stand for 10 minutes.

SS25 MAINTENANCE
Remove the overflow pipe and wait until the tray is empty. Put again the overflow
pipe. (In machines provided with discharge valve should be activated manually).
Refill the water tray to the maximum level with the same solution. Connect the
machine (close faucet), by pressing the switch 3 on the electronic board and at
the same time witching the unit on with the main switch (to start cleaning with no
cooling production) and wait 20 minutes. In old units, mechanical ones, place the
timer on defrosting before turning on the unit.
Open faucet, put the timer forward up to the harvest cycle and once the ice has
fallen disconnect the machine and put the timer in defrosting position.
WARNING:** Discard ice produced during cleaning procedure.
NOW STARTS THE SANITARY CLEANING.
Connect the machine once it has finished entering water, remove the evaporator
cover and pour lye (one glass). Wait for 20 minutes.
Put the timer foward up to defrosting position. Once the ice has fallen, THROW
AWAY THIS ICE and let the machine produce another complete cycle.
IMPORTANT: ** Discard ice produced during this procedure.
Clean and assemble all the components. Verify that the grill is cleaned and that
cubes slide properly. Check that any strip gets blocked in the curtain. Check
and/or change the water inlet filters.
Check the adjustments of the cycle thermostat (cubes more or less filled) and
that at the end of the cycle the frost is closed to the compressor.
CHECK THAT THE NOZZLES ARE PROPERLY PLACED, THAT THE FORMED
WATERFANS ARE UNIFORM AND ALL EQUAL. If necessary, disassemble,
clean and put again in the right position.
Ice bin cleaning.
Unplug the machine, turn off water supply, and empty storage bin of ice.
Wipe with a kitchen cloth soaked in lye and detergent.
If white lime stains do not vanish, rub with some lemon or vinegar, wait for a few
minutes and wipe with the cloth again. Rinse with plenty of water, dry, and run
the machine.
Outside cleaning
Follow the same procedure as for the ice bin.

SS25 MAINTENANCE
Spray nozzles and connecting pipes
Remove the curtain (it can be cleaned with vinegar or phosphoric acid, rinse,
clean with lye, rinse)
Remove the metal grill and clean likewise.
Pull upwards the connecting pipe. It has been assembled by pressing into place.
Disassemble the nozzles and the connecting tube covers and clean them.
Disassemble and clean the main filter of the production unit. (It is assembled by
pressing into it)
Assemble the filter, nozzles and connecting tube.
ATTENTION: IT IS ESSENTIAL THAT SPRAY NOZZLES ARE COMPLETELY
PERPENDICULAR TO THE CONNECTING TUBES, OTHERWISE THE CUBES
AT THE ENDS MAY NOT RECEIVE WATER.
Place the grill over the nozzles, with the back slots secure.
Install the curtain, ensuring that all of the strips can move freely.
Run the machine but DISCARD THE FIRST SET OF ICE CUBES.
