•

 

For best operating conditions the hot water should be approximately 60˚C. 
The hot water should not exceed 65˚C or the cold water exceed 35˚C. 
Temperatures above these may cause the machine to fault or cause 
damage to the machine.  

•

 

If you have an uncontrolled water-heating source (e.g. a wet back or solar 
heating) you should have a tempering device fitted. This will ensure the hot 
water temperature remains within safe limits. For the most suitable type of 
tempering device we recommend you contact a local plumber or plumbing 
supply merchant.  

•

 

Inlet Water Pressure 5psi (35kPa) to 150psi (1MPa) Static.  

Note: If using a header tank then the outlet of the header tank must be at 
least 2 metres above the top of washer console.  

•

 

Minimum flow rate from the tap, supplying the washer, should be greater 
than 6 litres/min (assumes ½ inch diameter pipes).
