[. . . ] Kinds of the items to be observed are categorized for clarification with the following pictorial symbols. This pictorial indication shows "Forced Execution". Don't push a finger or a stick into the air If there is a combustible gas leakage from other appliances, ventilate the inlet or the outlet. A fan with a high rpm will If operation were to be injure you. [. . . ] Incomplete combustion could occur on the It could cause a fire. Do not wash Energy Recovery Ventilators with water. Don't touch with wet hands When water spills, it is likely to enter inside the unit and degrade electric insulation, possibly Prohibited resulting in an electric shock. It could cause deterioration of foods or other problems. Ask the sales office or the engineering shop to perform the work. The system should never be used for any other purposes than intended such as for preservation of foods, flora and fauna, precision devices or work of art. Don't incline Energy Recovery Ventilators when removing the unit. Otherwise, water remaining inside is likely to drop and wet the furniture or other property. If the power is left on, any build-up of dust could cause a heat generation or a fire. If Energy Recovery Ventilators are not used for a long period of time, switch the exclusive circuit breaker "OFF" for safety reasons. Don't blow directly towards animals or plants. Do not handle switches with a wet hand. Energy saving ventilation Thanks to efficient recovery of thermal energy lost during Ventilation (load incurred by outside air), you can save an airconditioning fee. Facility saving Thanks to a drastic reduction of load incurred by outside air, you can make air-conditioners more compact in parallel with the recovery of thermal energy. Humidity adjusting effect In a cooling mode, a highly humid open-air is brought near to a dehumidified room atmosphere and then supplied. In a heating mode, a room humidity is transferred to the dry outside air and then supplied. Comfortable and consistent ventilation Ventilation is available with least possible fluctuation of a room temperature. Since exhaust and air intake are performed simultaneously, a stable ventilation is possible even in a highly airtight room. Sound shield effect The ducts of the unit and the heat exchange element are characteristic of sound shield effect. Thus, it prevents an outside noise from coming in the unit and also sound inside the unit from going out, so that the office and store environment can be preserved. [. . . ] Failure to do so may cause dust and dirt to build up on the heat exchange element, lowering its efficiency and rendering it inoperable. In particular, suddenly turning the switch on and off will not only cause improper operation of the unit, but will also affect the relay inside the switch, and may damage it. Note that when installing a unit body upside down, its printed indication is in a reversed position. Open air is thermal-exchange with room air to bring it closer to a room temperature and humidity, before taking it in the room. [. . . ]
