4.4.1. Water Supply Installation
Connection of the Water Supply Hose for the Humidifying Water Circuit
!
CAUTION
•
Remove packing sponges from the float level cups before supplying water to the
chamber. Failure to do so can cause water to overflow in the humidity system and
spill water on your laboratory floor making the floor extremely slippery.
Attach supply water to the water supply fitting on the left side of the chamber. The supply water
must be from a purified* water source. The water supply should have a pressure between 20 ~
50 psi to assure proper operation of the humidifying circuit.
*The type of purifying system does not matter, but the purified water should be filtered (5
micron), have a conductivity of 0.2µS/cm to 10µS/cm, and a maximum of 2mg/L of free chlorine.
If your chamber is equipped with an optional water supply tank please see the option manual for
the water supply installation procedure.
