Installing the Drain Hose
If the end of the drain hose does not fit to the drain
line, use a drain extension kit (optional) that is
resistant to heat and detergent.
• This should be available from a plumbing shop
or a hardware store.
Connection to the Waste Spigot
Check the waste spigot when initially installing. An
OE error can occur when the waste spigot below
the sink is not drilled out properly. To connect the
drain hose, drill out at least a 15 mm diameter hole
in the waste spigot before connecting and
securing.
CAUTION
• Make sure that plastic debris is not remaining
inside of spigot after it has been drilled out.
• Do not attempt to open the waste hole with a
screwdriver and hammer. This will induce debris
to become stuck and cause a malfunction.
• Caution should be taken when passing hoses
through Cabinetry holes as they may have sharp
edges and could damage the hoses. Smooth or
sand edges to avoid damaging the drain or inlet
hose.
• Make sure that the line is not kinked or sharply
bent.
• Make sure the drain hose is straight before
feeding the end of it through the hole for the
water supply.
To prevent siphoning, one of the following
methods must be used.
Method 1
When the drain hose is connected to a waste
spigot, the hose must be looped up to the
underside of the bench top and secured.
Method 2
When the drain hose is connected to a separate
standpipe
a , it is essential that an airtight
connection
b be made. If not, it can induce odours.
• Standpipe diameter is at least 40 mm.
