Junction Box Installation
As shown by the Figure at the right side: connect the water inlet pipe, air inlet pipe and water outlet pipe of the unit with the water source, air source and water outlet; when connecting, please make sure the air inlet pipe and the air inlet pipe is airtight; otherwise water or air may leak from the connecting interface. Finally connect the earth wire with the ground.According to the installation position of the unit, lay the water inlet, air inlet and water outlet pipe in the desirous position; the water inlet pipe and the air inlet pipe must be of PVC material with the specification of ø8×ø5 (i.e. ZG1/2〞); each of them must be connected by the elbow. The water outlet pipe to be used must have the inner diameter more than 27.5mm; it will be enough if the water outlet is reserved. Do not let the height between water outlets and dental chair’s installation floor be more than 100mm; otherwise the water inside the outlet pipe may flow back. Keep the water outlet downwards. Do not twists, protrude or corrugate the pipe, and do not put the water outlet into water.
