possible spillage from combustible appliances.
CLEANING FILTERS AND CORE
Air filters should be cleaned twice a year. The standard filters supplied with your
ventilator are removable and washable. Core should be cleaned twice each year.
1. Open ventilator door by loosening draw latches on top of unit and swinging door
open. For easier access, remove door by moving it right to disengage hinges.
2. Carefully grip ends of core, (be careful not to damage the aluminum fins); then
pull evenly outward. Core fits tightly, but slides out of channels.
3. Once core is removed, filters can be removed by detaching the clips holding
them in place. Note clip installation for reassembly.
4a. ERV core: Vacuum the ERV core or rinse with cold water. Do not use soap, dish-
washer, or a pressure washer.
4b. HRV core: Soak and rinse the HRV core in warm soapy water. Do not use clean-
ing solutions.
5. Wash the filters in warm soapy water.
6. Place the clean filter (wet or dry) over the core and secure it in place with the
clips.
7. Reinstall core by sliding it into the four corner channels. (Water cannot damage
gasket and label on core ends, so it is not necessary to remove them from the
core.).
NOTE: The core is designed to appear to protrude from the cabinet approximately
1/8 in. (3mm) so the access door fits tightly against the core.
