GTS HUMIDIFIER LX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
1.
Annually
(also recommended when maintenance is performed)
• Inspect tank, piping, and gaskets for water and gas leaks.
• Inspect condensate lines for blockage and verify condensate neutralizer
is in working condition (pH above 5).
• Inspect venting bird screens for blockage. Clean or replace if damaged.
• All safety devices in the control circuit should be cycled on and off to
verify they are functioning. These include:
- High limit switch
- Airflow proving switch
- Low water level probe. Pull out probe plug; fill valve should energize.
- Flue temperature sensor. Observe the temperature read out on the
Vapor-logic display during normal operation. The temperature will
fluctuate slightly during refill events.
- Tank temperature sensor. Observe the tank temperature read out on
the Vapor-logic home screen during a cold start of the humidifier. The
temperature will gradually increase to boiling temperature.
2.
Seasonally
(or as required, depending on water quality)
• Clean tank
- Drain tank.
- Remove cleanout plate and dispose of any loose scale that has
collected in the tank. Do this before the scale buildup reaches the
bottom of the heat exchanger.
- Inspect the area inside the tank in front of the drain valve fitting and
thoroughly clean all scale and mineral buildup from that area.
- Replace the cleanout plate using new gaskets.
• Dismantle and clean drain valve and associated piping
• Clean the probes
- Access the probe assembly through the round pop cover on the roof
panel.
- Disconnect the probe plug and cable assembly and unscrew the
probe rod assembly from the humidifier probe housing.
- Inspect the probe housing and clean, ensuring that all the housing
passageways are clear.
- The scale should flake off easily from the probe assembly rods.
- The bottom 3/8" (10 mm) of each rod is the sensing portion; clean
these areas with a wire brush, abrasive pad, or steel wool.
- Inspect the composite plastic probe head for any signs of cracking,
roughness, or deterioration. If found, replace entire probe assembly.
- Reassemble the probe assembly.
• Clean the skim/overflow port
