Frequently Asked Questions - VAM150FCVE DAIKIN

How often should I clean the air filter?

At least once every two years for general office use. Clean more frequently if necessary. Lightly pat or vacuum, and if heavily soiled, wash with water, dry in shade for 20-30 minutes before reinstalling.

What does the 'FRESH UP' mode do?

'FRESH UP' increases the volume of either outdoor air supplied (to reduce odors from kitchens/toilets) or exhaust air from the room (to contain hospital odors and bacteria). It helps control pressure imbalances.

Can I operate the HRV without the air conditioner?

Yes. In a VRV system, set the air conditioner to FAN VENTILATION mode and low fan speed. Or use the dedicated remote controller (BRC301B61) for independent operation.

What do the error codes on the remote controller mean?

Common codes include: 64 (r thermistor malfunction), 65 (air thermistor malfunction), 6A (stepper motor malfunction), U5 (transmission error), UA (faulty installation setting). Refer to the manual for full list and corrective actions.

How do I clean the heat exchange element?

Use a vacuum cleaner with a brush attachment. Gently brush the surface without crushing the element. Do not wash with water. Reinstall the air filter and maintenance cover securely.

What is the purpose of the bypass mode?

Bypass mode allows air to flow directly without passing through the heat exchange element. It is used when outdoor temperature is mild to provide natural ventilation without energy recovery.

Why is my unit not operating at all?

Check for power failure, blown fuse, or tripped breaker. Also verify if the remote controller shows 'operation control method' or 'operation standby' indicators—in those cases the unit is controlled by the air conditioner or in preheating/cooling mode.

Can I install this unit in a bathroom?

No. The manual warns against installation in places subjected to moisture like bathrooms, as it can cause electric leak, shock, or other failures. Avoid high temperature or direct flame areas.

How do I reset the filter cleaning indicator?

Press the 'Filter signal reset button' on the remote controller (BRC301B61) after cleaning the filter. The icon will disappear.

What maintenance is required for the damper and motor?

Only qualified service persons should perform maintenance. The damper motor is sealed and requires no routine user maintenance. Ensure the maintenance cover is securely closed after any inspection.
