Assembling and checking after cleaning and
maintenance
CAUTION
Securely install parts after cleaning and maintenance.
Injury could result if parts fall.
1. Install the filter on the filter case by following the
disassembly procedure in reverse.
- Make sure that the filter is not protruded from the filter
case.
2. Install the supply air filter case on the Lossnay unit.
3. Turn the three supply air filter fixing knobs to secure the
knobs to the Lossnay unit.
4. Install the exhaust air filter case to the Lossnay unit.
5. Turn the two exhaust air filter fixing knobs to secure the
knobs to the Lossnay unit.
6. When you have finished assembling the Lossnay unit,
press the ON/OFF button on the remote controller to check
the following:
- Check for emission of abnormal noise.
- Check for normal air flow.
- Check for air leakage from the installation section of the
supply air filter case or exhaust air filter case.
7. Reset the filter cleaning sign.
- For details on how to reset the filter cleaning sign, see
page 9 or page 12.
Note:
- In some operating environments, dew condensation
water or snow/mist water droplets may adhere to
the filters. This, however, is not a problem in product
performance or quality.
- Do not forget to install the filters inside the Lossnay
unit. (Doing so results in dirt clogging the surface of the
Lossnay core or a drop in fan speed.)
- Use filters (sold separately) to suit your specific
application if you are worried about small insects getting
inside or small dirt or dust particles.
