Basic Maintenance
Although Seresco equipment is built for minimal service downtime, periodic preventative maintenance is required
to ensure maximum reliability, safety, and operating efficiency.
Maintenance and Safety
Only qualified/properly trained personnel should attempt to perform respective maintenance tasks.

When it is necessary to work with live electrical components, have a licensed electrician or other qualified
professional perform the required task.

Be properly trained and equipped. Some maintenance tasks may involve usage of power tools, chemicals, etc.
Refer to such tools and materials data (manuals, MSDS, etc.). Personnel performing such maintenance tasks
should be:
o
Properly trained to handle such tools and materials safely
o
Equipped with proper personal protective equipment

Turn the power off. Before performing any maintenance, disconnect all electrical power, including remote
disconnect, and discharge all energy storing devices (VFDs, etc.) before servicing. Follow proper lockout
procedures to ensure that power cannot be accidentally restored. Failure to follow provided safety warnings
and labels could result in serious injury or death.

Be aware of potential hazards. The equipment contains moving mechanical parts, components under high
refrigerant pressures and surfaces with high temperatures. Before entering the dehumidifier and/or
performing any equipment maintenance work, make sure that all moving parts are stopped, and it is safe to
perform required task.
Maintenance Key Points
Here are some basic/key maintenance considerations, pertinent to all dehumidifiers and their auxiliary systems:

Dehumidifier in mechanical room. No chemicals should be stored in the same mechanical room where the
dehumidifier is installed. Chemical fumes/off ‐ gas can cause premature deterioration of the equipment.
o
Store chemicals in a separate, well ‐ ventilated room.

Access to the Equipment. Ensure that the equipment is accessible (minimum clearances are maintained):
approaches to the dehumidifier are not restricted/limited with materials in mechanical room (indoor installed)
or with snow (outdoor installed dehumidifiers, OACC and OAFC).

“MUST DO” maintenance task. Although all other maintenance tasks are as important, these two maintenance
tasks are the most common and most helpful :
o
Maintain clean air filters (return, outdoor air filters, etc.). Make sure to replace dirty filters regularly.
o
Maintain clean air ‐ side coils (especially Outdoor Condenser or Fluid Cooler). Make sure to clean coils
regularly.
WARNING!
To ensure equipment longevity and proper and efficient operation, the dehumidifier and its
auxiliary systems and devices (outdoor condenser, fluid cooler, boiler package, etc.) must be maintained properly
and regularly. It is recommended to create a facility ‐ specific Routine Maintenance Program .
Failure to maintain the equipment properly and regularly could result in personal injury, equipment damage or
malfunction and will void the equipment warranty.
