These Installation Guidelines must be followed to ensure the unit will operated as intended.
Installations must be carried out by a qualified and licensed tradesperson.
Service Connections
NOTE: Plumbing connection must comply to AS3500 and Watermark Certified.
Waste connection
• HOT AND COLD WATER CONNECTIONS ARE REQUIRED. The machine can be connected to any normal
mains pressure hot and cold water supply. A back flow prevention air gap is incorporated in the design of the
water tank. Complies to AS 2845.2
• The water supply is to be connected to an isolating valve or cistern stopcock placed approximately 1200mm
from the floor to the right-hand side of the machine. (Preferably not behind the machine)
Cold water: Flow pressure Kpa 100 min 350 max. Temperature 15° - 25° C
Hot water: Flow pressure Kpa 100 min 350 max. Temperature 55° - 60° C
Minimum water flow for 100Kpa
If inlet water flow pressure is higher than 350 Kpa an inline pressure reducing valve should be fitted.
Soil Line
• Hot water. Discharge temp 75° – 80° C. Soil line to comply to AS3500
• Soil line connection is by a pan collar or other preferred method. If the belled end on the polyethylene moulded
trap is not required it can easily be cut off to provide a straight pipe connection.
• Level the unit by using the flanged screw in legs and if possible maintain approximately 100mm floor clearance
for ease of floor cleaning. We recommend that some of the leg flanges are fixed to the floor via stainless self
tapping screws to prevent sideways movements and damage to services and soil line connections.
• The soil line should protrude from the floor or wall at a minimum of 100mm
