1. Main drain
• Always lay the drain with downward inclination
(1/50 to 1/100).
Prevent any upward flow or reverse flow in any
part.
• 5mm or thicker formed thermal insulator shall
always be provided for the drain pipe.
2. Safety drain
• There is no need to
provide a trap for the
safty drain. If the

connected to the
main drain pipe,
make the connection
below the trap on the
main drain pipe.
