5.7.4 Checking Water Level in the Humidifying Tray
Check to confirm water in the humidifying tray is high enough.
Procedure:
1. Check that the humidifying heater is completely under water and that water is not overflowing from the
humidifying tray. An inappropriate water level will destabilize temperature and humidity control.
Reference: When either the humidifying heater is not completely under water or water is over-
flowing from the humidifying tray, it is possible that the chamber is not level or that
the water level in the humidifying tray water level regulator is too low/high. If the
chamber is not level, level it as explained in “How to Install” on page 38. If water
level in the humidifying tray water level regulator is too low/high, regulate it as
explained under “Reference” on the next page.
5.7.5 To Check Water Level in the Humidifying Tray Water Level

regulator.
