Water Supply
•
For the best operating conditions the hot water temperature should be approximately 149 ˚ F.
•
The hot or cold-water temperature should not exceed 167 ˚ F (75
o
C) or 95 ˚ F (35
o
C) respectively.
Temperatures above these may cause the machine to fault or cause damage to the machine.
•
If there is an uncontrolled water-heating source (e.g. a wet back or solar heating) a tempering
device should be fitted. This will ensure the hot water temperature remains within safe limits.
For the most suitable type of tempering device we recommend contacting a local plumber or
plumbing supply merchant.
•
Inlet Water Static Pressure 3psi (20kPa) to 150psi (1MPa).
Note: If using a header tank, then the outlet of the header tank must be at least 2 metres
above the top of the clothes washer.
•
The water supply flow rate should be greater than 1.6 gallons (6 litres) per minute (assumes ½
inch diameter pipes).
•
The minimum height of the taps to clear the top of the machine is 45.25 inches (1150mm).
