Owner's Manual 7 ENGLISH n Operation Prior to Operation Prior to Operation Preparing for operation 1. Contact an installation specialist for installation. 2. Plug in the power plug properly. 3. Use a dedicated circuit. 4. Do not use an extension cord. 5. Do not start/stop operation by plugging/unplugging the power cord. 6. If the cord/plug is damaged, replace it with only an authorized replacement part. Usage 1. Being exposed to direct airflow for an extended period of time could be hazardous to your health. Do not expose occupants, pets, or plants to direct airflow for extended periods of time. 2. Due to the possibility of oxygen deficiency, ventilate the room when used together with stoves or other heating devices. 3. Do not use this ventilator for non-specified special purposes (e.g. preserving precision devices, food, pets, plants, and art objects). Such usage could damage the items. 4. This unit cannot control room temperature. If this is needed, do not install the ventilation unit alone, but rather install another indoor unit. Cleaning and maintenance 1. Do not touch the metal parts of the unit when removing the filter. Injuries can occur when handling sharp metal edges. 2. Do not use water to clean inside the ventilator. Exposure to water can destroy the insulation, leading to possible electric shock. 3. When cleaning the unit, first make sure that the power and breaker are turned off. The fan rotates at a very high speed during operation. There is a possibility of injury if the unit’s power is accidentally triggered on while cleaning inner parts of the unit. Service For repair and maintenance, contact your authorized service dealer. 8 Ventilator Introduction ENGLISH Introduction 1 3 2 5 12 11 13 14 6 9 4 10 8 7 1. Maintenance cover 2.

Inspected part Feed water tank Solenoid valve Content of maintenance Items to be inspected Solution Problems if maintenance is not carried out Check for operation of float switch Clean if it does not work properly due to build-up. Insufficient humidifying. Overflowed feed water tank. Check for dirt Clean if very dirty. Weak fan strength. Reduced humidifying capacity. Check for shutting and opening. Check in a similar fashion when checking the float switch operation. Replace if it doesn’t work. Insufficient humidifying. Overflowed feed water tank. (Increased tap water consumption.) Replacing the Humidifier element 1. The humidifier element should in general be replaced once every three years when supply water is soft water, but outside factors (water quality, operating times) may shorten its productive life. 2. Contact your dealer if you have any questions. NOTICE This note is only applied to model that there is humidity function. When humidifying fails, the remote controller does not display any error code. (just twinkle the icon of Humidification “ ” for 30 minutes and disappeared) Usage under that status will lead to insufficient humidification and increased tap water consumption. The solenoid valve and float switch should be checked at the beginning of heating season. Owner's Manual 23 Humidifier Maintenance Maintenance Cycle • Recommended maintenance cycle of each part.
