Homeowner Maintenance
Properly maintain your vertical fan coil for long-lasting home comfort and to minimize potential performance issues. Homeowners may
perform basic maintenance however; we strongly recommend that fan coils are
professionally maintained
twice per year. Contact Unilux CRFC
Parts & Service for our full line of service programs.
Change Your Supply Air Filter
Supply air filters sit behind the access panel and trap dust, dirt and pet dander
from entering your fan coil. Changing filters improves indoor air quality and helps
maintain your unit. We recommend changing supply air filters every 2-3 months.
Open your access panel and slide the filter up in the tracks to remove. Replace it
with a new Unilux filter. To browse and order air filters for your Unilux CRFC, check

Professional Maintenance
Fan coils should be serviced by a qualified service technician every 6 months.
This ensures the fan coil is in good working order and prevents
deterioration. Professional technicians should inspect all of the components below and follow safe plumbing and electrical practices.
Drain Pan
Vacuum the pan to remove all debris. Check the pan for leaks and
test the drain. Pour a cup of water into it. If it drains quickly, it’s okay.
If it doesn’t drain, snake the drain with a flexible tool.
Hydronic Coil
Inspect and vacuum the coil at the start and end of heating season
when the coil is dry. Vacuuming the coil clears dirt and debris,
which improves indoor air quality and helps prevent the drain
pan from clogging.
Copper & Stainless-Steel Tubing & Hoses
Inspect copper tubing and hose connections to the risers. Fix any
water trickle immediately.
Motorized Valves
Inspect motorized valves to ensure proper operation. Ensure you have
clean running water passing through the unit.
Motors & Blowers
Inspect the main supply air fan to ensure proper operation. Clean the
blower during inspection to remove dust and dirt. This helps prevent
the wheel from becoming unbalanced. Do not dislodge the balancing
weights on the wheel while cleaning.
Insulation
Inspect the insulation on the walls of the unit for wear and tear as
well as mould growth. If mould exists, a remediation expert should
be consulted.
Warnings & Safety Considerations
Your fan coil operates using components that require electricity and water under high pressure – potentially very hot water. Before using or
maintaining your fan coil, it is very important that you understand all of the safety warnings located inside the cabinet.
Water Hazard
Indicates a potential hazard due to water which could result
in flooding.
Hot Water Hazard
Indicates a potential hazard for burning due to extremely
hot water.
Electrical Hazard
Indicates a potential electrical hazard which could result
in electrical shock and/or fire.
Sharp Blades Hazard
Indicates a potential hazard due to sharp revolving blades
which could result in cuts or amputation.
Freeze Hazard
Do NOT leave windows or doors open when the outside
air temperature is at or below freezing. Freezing air will
freeze the water in your unit’s coil, potentially causing
flooding and water damage.
