2.3 Plumbing
These installation guidelines must be followed to ensure the device will operate as intended.
Installations must be carried out by a qualified, licensed tradesperson.
Service Connections
NOTE: Plumbing connection must comply with AS/NZS 3500.1 and be Watermark Certified.
Waste Connection
•
HOT AND COLD WATER CONNECTIONS ARE REQUIRED. The device can be connected to any potable mains pressure
hot and cold water supply as 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 device (preferably not behind the device).
Cold water: Flow pressure 100-350Kpa max. Temperature 15° - 25°C
Hot water: Flow pressure 100-350Kpa max. Temperature 55° - 60°C
Minimum water flow for 100Kpa 9.377L/min
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 must comply to AS/NZS 3500.2
•
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 device by using the flanged screw in legs and, if possible, maintain approx. 100mm floor clearance for ease of
floor cleaning. Malmet recommends affixing some of the leg flanges 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.
