Do not install this product in a location where acid, alkali or organic solvent vapors, paints or
other toxic gases, gases containing corrosive components or high concentrations of oily
smoke are present. (Failure to heed this warning may result not only in malfunctioning but also
fire, power leakage and electrical shock.)
Do not use this product outside the range of its rated voltage and control capacity. ERP
1200, ERP 2200 and ERP 3200; Single phase, 220- 240 V, 50 Hz., ERP 4200 Three phase,
380- 400 V, 50 Hz. (Failure to heed this warning may result in fire or electrical shock.)
Install this product in an environment where the temperature ranges from -10 °C to +40 °C
and the relative humidity is less than 80%. If condensation is expected to form, heat up the
fresh outside air by a duct heater etc.
Select a position for introducing the outside air where no exhaust or combustion gases will
be sucked into the fresh air duct and where it will not be covered by snow (Failure to ensure a
supply of air can result in producing a state of Oxygen deficiency inside the room.)

metal, these ducts must be installed in such a way that they will not make electrical contact
with metal laths, wire laths or metal sheets. (Power leakage can cause ignition.)
The outside ducts must be tilted at a gradient(1/30 or more) downwards toward the outdoor
area from the main unit, and properly insulated. (The entry of rain water may cause power
leaks, fire or damage to household property.)
Gloves should be worn during installation. (Failure to heed this warning may result in injury.)
A dedicated circuit breaker must be installed at the origin of mains power supply. This circuit
breaker must be provided with a means for locking (lock and key).
