4. Drainpipes
(a) Keep a gradient (1/50-1/100) of the drainpipes and avoid lobbing or curving.
(b) When connecting the drainpipe to the equipment, don't apply too much force on one side of the equipment.
Meanwhile, the piping should be positioned as close to the equipment as possible.
(c) For the drainpipe, the general purpose hard PVC tube can be purchased at local shops.
During the connection, insert the end of PVC tube into the wash port and fasten it with drainage hose and thread
clip. Binding agents shouldn't be used to connect the wash port and drainage hose.
(d) When the laid drain piping is used for multiple equipments, the public piping should be lower about 100mm than
the wash ports of equipments, as shown in the gure. Thicker pipes should be used for this application.
