4.2. Water and Drainage
Water quality influences ice hardness, flavour, and quality as well as condenser life.
Keep in mind the following points:
a) WATER IMPURITIES: Major impurities are eliminated by the two small wire mesh filters
provided and installed on either end of the water inlet hose. Filters should be cleaned/replaced
regularly depending on purity of water. For minor impurities we recommend installing a 5-micron
filter such as the one provided with the unit: Part # ITV 207499. This filter will need to be
replaced only when machine stops due to insufficient water flow (filter is obstructed with
impurities).
b) WATER WITH MORE THAN 500 PPM: Ice will be less hard and tend to adhere. Lime
deposits may impede proper function. In water-cooled models, condenser obstruction is likely.
Installation of a high quality water softener is recommended.
c) CHLORINATED WATER: In most cases the filter which is included in the machine should be
sufficient. However, if mains water smells or tastes of bleach, this indicates an excess of
chlorine, which may eventually corrode the stainless steel auger. A carbon filter will remove
chlorine in water (average filter life: 6 months), not included with machine. (Part # ITV 207509).
(NOTE: You may encounter water with ALL aforementioned properties.)
d) PURIFIED WATER: A 10% reduction in overall production may occur.
4.3. Connecting unit to water source (water-cooler units)
• Use 1.3 m. flexible tube (with the two filters attached) provided. NOTE: We advise using a
single faucet fixture.
• Water pressure should be between 0.7 and 6 Kgs/cm2. (10/85 Psi.)
• If water pressure exceeds these values, installation of appropriate corrective units will be
necessary.
• It is important that water tubing does not come close to or in contact with any heat sources
or heat generated by unit as this could decrease production.
4.4. Connecting unit to drain (water-cooled models)
• Drain must be located at least 150mm below machine level. Drain tube must have an inner
diameter of 30mm and a minimum gradient of 3 cm per metre.(3%)
