GTS HUMIDIFIER LX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
MAINTENANCE
Inspection and maintenance (continued)
- Water should drain from the skimmer drain pipe after each daily
probe check. This should be verified visually by a weekly inspection.
- Loosen deposits in and around the skimmer/overflow port with a
long tool such as a screwdriver.
- If flow through the water seal/P-trap is diminished due to mineral
accumulation:
- Remove the water seal piping from the humidifier and flush out.
- Replace the water seal with new piping if the minerals have
hardened in the water seal.
• Clean the tank temperature probe — Inspect the probe for mineral
accumulation. The probe is located on the heat exchanger plate just
above the combustion assembly. Use stainless steel wool to clean the
probe.
• Inspect blower motor — A lubrication port is not provided, therefore
lubrication is not required.
• Remove dust — Using a vacuum, remove all dust from areas around the
motor, vent fan(s), and louvers that allow air to the shrouded area.
• When the maintenance requirements are complete:
- Replace cleanout plate and tighten the nuts on the plate. Torque the
nuts to 60 in-lb (6.8 N-m).
Note: Always install a new gasket when the clean out plate is
reassembled.
- Verify that the probe head is secure and that the probe plug and
cable assembly are plugged into the probe rod holder.
- Verify that the drain valve assembly is in the closed position.
• After confirming the plumbing connections are secure, perform a tank
de-scaling procedure using the DriSteem GTS humidifier tank de-scaling
kit.
• When the chemical de-scaling process is complete:
- Replace and secure all covers and doors.
- Turn on the water supply.
- Turn on the electrical power.
- Turn on gas.
- Do not leave humidifier unattended. Allow the humidifier to cycle
through multiple fill cycles and verify that the humidifier cover,
cleanout plate, and probe holder gasket are not leaking.
• Verify proper operation of the humidifier after servicing is complete.
Important:
Minimum supply water pressure is 25 psi
(172 kPa).
