GTS HUMIDIFIER LX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Product overview
WATER LEVEL CONTROL
The LX series of GTS humidifiers control water level using a three-rod probe
(see Figure 9-1). All water types and conductivities work with the universal
water system. The user does not need to select a new water type or change
hardware to change water types. Additional valves and Vapor-logic algorithms
measure and control the water level for optimum efficiency and low water
safety conditions. Vapor-logic automatically provides a steady output while
maintaining the water level between the bottom and middle probes.
