Install and usage

• The installation should be completed by a professional service staff.
- Do not install the unit in the place with high temperature or fire., as it may cause the filter distortion and burn out the motor.
- Do not install the unit in the kitchen which has a lot of smoke. Filter and ERV/HRV core is useless as long as oil fumes attach to it and can easily cause fire.
- Do not install in the place with high humidity such as bathroom etc. The appliance in contact with steam may cause fire and/or electric shock.
- Do not install the appliance in the ceiling with insufficient strength or alternatively straighten the fixing surface before installation.
- Do not install in places which have combustible gas. It may cause fire.
- Caution! This product cannot be used for ventilation with open-type burning appliances (heaters)!
- Do not install the unit and outdoors or with air inlet near the machinery factory or research facilities. Avoid the environment which has acids, alkalis, organic solvents, paints, harmful gases or corrosive composition of gases. It may damage the appliances or cause fire.
• Do not install the air inlet in the kitchen.
• If the air duct is installed tilted outside it may cause water seepage.
• In order to prevent condensation an extension should be installed from outdoor to indoor.
• Install protection of the air ducts, inlets and outlets to prevents small animals getting in.
• During installation following piping should be avoided:

a b c

a) Bend
b) Bend many times
c) Reduced diameter

• A circuit breaker should be installed to prevent electric shock or any short circuits.

- Do not reverse the appliance, it may fall down and cause injury.

- After completing installation do a test run and check if any problem occurs (blockage, restrictions, abnormal noise during work).

• The appliance is controlled by the included controller with a knob.

Maintenance

a) When the ERV/HRV is used for a long time, the filter will be dirty and clogged by dust, it may decreasing the air volume, impact the ventilation, increase the noise. Please clean the filter periodical, especially in a hostile environment (a higher number of dust).

Filter maintenance:

• Unlock the hanging chain under the make the access panel upward
• Please hold the indoor side filter and abstract it horizontally (A on the picture below).
  • Use a vacuum cleaner to suck the attached dirt and dust away.
  • The installation of indoor side filter is following the reversed steps.
• Please hold the outdoor side filter and abstract it horizontally (B on the picture below)
• Please use a vacuum to suck the attached dirt and dust away.
  • The installation is in the reversed steps, please noticed the marked direction.

a) The duct fan should be cleaned and check annually (clean motor; parts cannot be exposed to moisture) to make it operate safe and prolong its life.

b) Cut the power supply before any maintenance and wait for the rotating elements to stop.

c) When there is an abnormal noise or significantly efficiency reduction, please check the bearing and replace it if necessary (done only by a qualified service technician).

d) Do not spray the device with a water jet or submerge it in water.

e) Do not allow water to get inside the device through vents in the housing of the device.

f) Do not use sharp and/or metal objects for cleaning (e.g. a wire brush or a metal spatula) because they may damage the surface material of the appliance.
