Quest IQ Compressor Wall OMM
Basic Maintenance
Although 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 HVAC system 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 HVAC systems and their auxiliary systems:
•
HVAC system in mechanical room.
No chemicals
should be stored
in the same mechanical room
where the
HVAC system 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 HVAC system are not restricted/limited with materials in mechanical room (indoor
installed) or with snow (outdoor installed HVAC systems, 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 Dry Cooler). Make sure to clean coils regularly.
WARNING!
To ensure equipment longevity and proper and efficient operation, the HVAC system and its
auxiliary systems and devices (e.g. dry cooler)
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.
