Inspection and maintenance

1. Annually (also recommended when maintenance is performed)

• Inspect tank, piping, and gaskets for water and gas leaks.

• 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.

– Redundant low water level probe

2. Seasonally (or as required, depending on water quality)

• Clean 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.

• Dismantle and clean drain valve and associated piping

• Clean the probes

– Access the probe assembly either from the electrical panel

or by removing the roof panel above the electrical area.

– 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. Remove the housing from

the tank by removing the cover plate from the tank.

– 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 rod assembly for any

signs of cracking, roughness, or deterioration. If found,

replace probe assembly.

– Reassemble the probe assembly.
