●
Perform the installation securely referring to the installation manual.
– Incomplete installation could cause personal injury due to fire, electric shock or the unit falling.
●
Do not install the product in a place where it is or might be exposed to inflammable gas leakage.
– When the unit is exposed to inflammable gas leakage, it could catch fire or cause explosion.
●
Make sure to use the part provided or specified parts for the installation work.
– The use of defective parts could cause fire or electric shock.
●
Do not install the product in the place where generates toxic gas from machinery or chemical factory such as alkali
solution, organic solvent, or paints.
– It may cause fire or gas poisoning.
●
Do not install the product in a place where it might be exposed to petroleum, steam, or sulphuric acid.
– When the unit is exposed to petroleum, steam, or sulphuric acid, unit falling or malfunction may take place.
●
Make sure the air intake is located far from an exhaust port of a burner.
– It may cause indoor oxygen shortage.
● Install the product inside heat insulation over the ceiling not to be contacted with the outside air.
– If the product is installed out of the insulation, it may result in electric shock or malfunction due to moisture generated in the
product.
●
Do not install the product in humid place such as bathroom.
– It may cause electric shock or malfunction.

1-2 Power supply and circuit breaker
● Turn off the sub power supply when you don’t use the product for a long period.
– If not, it may cause power consumption or fire.
●
Install a ground leakage breaker depending on the installation place.
– If not, it may cause electric shock.
●
Ensure that the national safety code requirements have been followed for the main supply circuit. Ensure that a properly
sized and connected ground wire is in place.
– Inappropriate wire may cause overheating of fire.
●
Unplug the product before get repaired.
– If not, it may cause electric shock.
●
Do not install the electric wire to get tension.
- The electric wire may disconnect and cause fire.
●
Do not utilize ERV wired remote control with wet hands.
– It may cause electric shock.
●
If the power plug is damaged, replace it by the manufacturer or qualified personnel to avoid the risk.
1-3 During operation
● Open windows for air circulation when a burner or other product leaks inflammable gas.
– If not, it may cause fire or explosion.
●
Make sure to keep winds from the product away from a burner.
– It may cause incomplete combustion.
●
Do not utilize the ventilator to preserve machinery, foods, animals, plants or cosmetic products.
– It may cause damage to the machinery, foods, animals, plants or cosmetic products.
●

●
Do not put the product under a great pressure or reinstall the unit on your own.
– It may cause fire or malfunction.
●
Do not utilize the product for air exchange when an open type burner is used.
– Separate measures for air exchange must be prepared when a gas or oil stove is used.
●
Ensure that indoor air should not flow into the outdoor air suction duct of the product.
– If not, indoor air may be contaminated to have a bad influence on heath of people.
●
Stop operating the product as soon as any error is found.
– Stop operating and turn off the unit when it smells burning or any error in operation is found. Contact a dealer or a qualified
installer. If continue operation of the unit, electric shock, fire or unit falling may occur.

2. Product Specifications
2-1 The Feature of Product
■ Energy Recovery Ventilation
The product helps save energy and drive down operation costs of heaters and coolers by recycling thermal energy (energy load)
efficiently.
■ Air Volume Control
Air volume control minimizes energy loss and cuts down on energy usage, even when duct resistance is low at the time of installation.
■ Automatic Operation
Operation mode and air volume are controlled automatically by sensing indoor and outdoor air conditions.
■ Exchange Mode
Heat-EX mode is utilized in summer and winter while usual ventilation mode is used in spring and autumn.
– Heat-Ex Mode : Energy loss is minimized by recycling energy exhausted when indoor heating and cooling.
– By-Pass Mode : The ventilation method is used when temperature gap of indoor and outdoor is not big. Outdoor air flows into
indoor.
■ High Sensibility Sensor (Option)
An optimal air condition is maintained through Carbon Dioxide (CO2) sensor and temperature sensor.
■ Humidity Control
Fresh air conditions are guaranteed by recovering moisture in winter while exhausting it in summer.
■ Operation at Cold Area
Optimized automatic ventilation operation is conducted to prevent condensation and air volume reduction.
■ Low Noise and Low Power
With highly efficient motor and optimized system design, operation noise and electric consumption is minimized.
