Water Quality: 550 ppm. total solids
Water Temperature: 15°C
Ambient Temperature: 20°C
Ice production and quality is heavily dependent on the following:
a) Ambient temperature
b) Water temperature
c) Water quality
d) Level of water in evaporator
The following graph illustrates variations in production according to these fact
production decreases as water temperature increases.
IT IS IMPORTANT THAT WATER INTAKE TUBE IS NOT CLOSE TO ANY HEAT SOURCE.
THIS WILL AFFECT ICE PRODUCTION AND QUALITY.
• Ambient temperature should be taken 4cm away from the centre of the front grille
• Water temperature should be taken inside the water trough. Check that water line and filter do
not receive hot air from condenser + fan. If so, then re-direct water inlet line + filter to avoid hot
air current.
• Ice quality can be improved by lowering the position of the water trough. The trough is attached
to a panel with two screws. This panel has several slots, so that the trough can be moved up or
down as required.
• The trough may be lowered up to 80mm (IQ 550/1100). This will result in decrease of
production (see dotted line in graph below), but harder, drier ice.
• Water content in ice (obtained by straining ice) may be as much as 10%
• Ice production also decreases with improved water quality. (See graph for approximate
production variations).
