FAQ
...
No Cooling / No Heating
- Causes: Dirty air filter; low airflow; air trapped in piping; insufficient water flow. - Solutions: Clean the air filter; bleed air from the system; inspect the water inlet valve and strainer.
Weak Airflow
- Causes: Clogged air filter; obstructed return air; low motor speed. - Solutions: Clean the air filter; clear the return air grille; inspect the motor capacitor.
Water Leakage
- Causes: Clogged condensate drain pan; blocked drain pipe; damaged insulation. - Solutions: Unclog the condensate drain pipe; repair/replace insulation; verify the installation slope.
Noise / Abnormal Sounds
- Causes: Dirty fan impeller; defective motor bearings; mechanical resonance. - Solutions: Clean the impeller; tighten loose screws; replace the motor bearings.
Inconsistent Temperature (Fluctuating)
- Causes: Defective motorized two-way valve; malfunctioning thermostat; unstable water pressure. - Solutions: Replace the two-way valve; calibrate or replace the thermostat.
Unpleasant Odors
- Causes: Dirty cooling coil; mold/mildew in the condensate drain pan. - Solutions: Clean the cooling coil; disinfect the drain pan.
Low Fresh Air Volume / No Airflow
- Clogged filters, air duct leaks/blockages, fan running in reverse - Clean/replace filters, inspect air ducts, adjust fan wiring
Excessive Noise / Vibration
- Dust accumulation on impeller, loose mounting, aging fan bearings - Clean impeller, secure unit housing, replace bearings
Indoor Odors / Contaminated Fresh Air
- Filter failure, dirty heat exchange core, exhaust fumes drawn into intake - Replace filters, clean/replace heat exchange core, adjust fresh air intake location
High Power Consumption / Poor Performance
- Prolonged operation at high speed, dirty filters, severe air leaks - Operate at lower speeds periodically, replace filters frequently, seal air leaks
