AKHV160 Heat Recovery Ventilator (HRV) AKHV160 - Use and Care

Filters (A)

• Dirty filters can reduce ventilation efficiency, result in unbalanced airflow and damage or shorten the life of the motors.

• Filters are located either on top or below the core depending on your exact model and remove easily by opening the front cover of the unit and sliding out.

Polyester Filters

• Vacuum every three months. Replaced every 1-3 years.

Option MERV Air Filters

• If optional air filters have been installed, they should be replaced every 3 months.

• When replacing, take special note of the airflow direction.

Fan (B)

• Wipe all parts with a dry cloth or gently vacuum the fan.

• NEVER IMMERSE ELECTRICAL PARTS IN WATER.

• No other service is required as these fans are designed to operate continuously without lubrication.

Condensate Drain (C) (HRV UNITS ONLY)

• Twice per year wipe clean the condensate drain pan

• Check the condensate drain and tubing to ensure they are free flowing.

• The tubing must have an “S” or loop that traps a quantity of water to prevent air from entering the unit via this tubing.

Recovery Core (D)

• The core (located behind the cover) should be removed and cleaned at least once a year

Unlatch the latch(es) and slide the door to right to release from hinges and clean as follows:

• ERV Units: Clean by vacuuming at least once a year. DO NOT USE SOAP, WATER OR ANY CLEANING AGENTS ON THE FIBER-MEDIA CORE.

• HRV Units: Clean using a mild detergent in cold water at least once a year. Make sure the core is completely dry before re-installing into the unit.

Exterior Hoods

• Regularly check the outside vents and clean any obstructions such as grass, leaves or other debris.

• Do not replace the screen with mesh smaller than 1/4” as this will restrict airflow.

• During winter operation, ensure snow and frost does not build up and restrict or block openings.

Grills & Duct Work

• Clean the grills when they are dusty or greasy with soap and water

• Check for punctures in the insulation jacket on the fresh air and exhaust air ducts.

• Repair any punctures using foil tape.

Annual Servicing: Your ERV/HRV should undergo annual general servicing by an accredited contractor. This servicing should include the following:

• The six maintenance items above

• A general check for proper operation. Controls and electrical connections should be inspected.

• Verification that intake and exhaust air flows are properly balanced.

• Re-balancing as necessary.
