Warning
Incorrect handling of the product may result in serious injury or death.
Electric shock
If you must inspect the circuitry while the power is on, do not touch the live
parts.
(Failure to heed this warning may result in electric shock.)
Modification is prohibited
Do not modify the unit.
(Failure to heed this warning may result in electric shock, fire and/or
injury.)
Proper electric work
Use the electric wires designated for electric work, and conduct electric work
in accordance with the “Electric Installation Engineering Standard”, the
“Indoor Wiring Regulations” and the installation instructions.

Names and functions of components
About the filters
| Features
---|---
Exhaust air filter| | Exhaust air side| The filter prevents clogging of the
internal parts.
Outside air filter (Replacement filter)| (P-100F5-E: Optional parts)| Supply
air side| When Lossnay takes in outside air to a room, the filter collects
dust, sand, pollen or the likes from outside air.
Note: Some fine particles or tiny insects may pass through the filter. The
high performance filter is recommended for higher collecting effect.
Outside air filter can be replaced with the following high performance filter.
High performance filter (Optional parts)| (P-100HF5-E)| Supply air side| The
filter collects dust more efficiently than the outside air filter.
Note: When using the high performance filter, install it in the filter frame
without using the filter stopper.

Troubleshooting
Work precautions
- When servicing, be sure to recreate the malfunction two or three times before starting repairs.
- When servicing, always keep proper footing.
- When servicing, always unplug the power cord from the outlet, or turn off the circuit breaker. Sufficient care must be taken to avoid electric shock or injury.
- Always connect the power wires properly.
(1) Service Flowchart
After checking the check items below, follow the troubleshooting 1 and 2 for
servicing.
Check items
- Condition of trouble
- Frequency of trouble: The date of starting operation and occurrence of trouble
- With or without working drawings: Equipment, wiring
