Cautions for Operation

DANGEROUS
■ Do not use as an air circulator for open-type burners (heaters).
When gas or oil stoves are used in the home. separate equipment for circulating the air should be used.
WARNING

• When any abnormal condition (scorching smell or others) is found. stop the operation immediately and switch the exclusive circuit breaker “OFF”.
  If you continue the operation without removing the cause, it could cause an electric shock or a fire.

• When the system needs a repair, consult your dealer.

• Don’t push a finger or a stick into the air inlet or the outlet.
  A fan with a high rpm will injure you. If the operation were to be attempted in such a situation, sparking at electrical contact points could cause an explosion.

• Modification of the system is strictly prohibited.
  Improper practice of repair could cause water leakage, an electric shock or fire.

• When the system needs a repair. consult your dealer.
  If there is combustible gas leakage from other appliances, ventilate the room by opening windows.

• Netting or something similar should be provided at the external air intake opening to prevent birds etc. interfering with the unit.
  Nests or other foreign objects should be removed. That could lead to a lack of oxygen in the room.

• If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly qualified person in order to avoid a hazard.

CAUTION

• It is strictly prohibited to place a container of combustible gas or liquid near Energy Recovery Ventilators or to spray it directly with the gas or liquid.
   It could cause a fire.

• Do not use outside the rated voltage.
   It could cause a fire or an electric shock.

• This appliance can be used by children aged 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge
   If they have been given supervision or instruction concerning the use of the appliance in a safe way and understand the hazards involved

• Children shall not play with the appliance.
   Cleaning and user maintenance shall not be made by children without supervision.

• Combustion apparatus should not be placed allowing a direct exposure to the wind of Energy Recovery Ventilators
    Incomplete combustion could occur on the apparatus.

• Don’t blow directly towards animals or plants.
  Likely to cause bad effects on animals and plants.

• Don’t put a container of water on Energy Recovery Ventilators.
  When water spills, it is likely to enter inside the unit and degrade electric insulation, possibly resulting in an electric shock.

• Do not wash Energy Recovery Ventilators with water.
  It could cause an electric shock.

• Do not handle switches with a wet hand.
  It could cause an electric shock.

• If Energy Recovery Ventilators are not used for a long period of time, switch the exclusive circuit breaker “OFF” for safety reasons.
  If the power is left on. any build-up of dust could cause a heat generation or a fire.

Cautions for Installation

CAUTION

• The system should never be used for any other purposes than intended such as for the preservation of foods. flora and fauna. precision devices or works of art.

• It could cause deterioration of foods or other problems.

• Don’t incline Energy Recovery Ventilators when removing the unit. 0 Prohibited
   Otherwise. the water remaining inside is likely to drop and wet the furniture or other property.

• Ask the sales office or the engineering shop to perform the work.

Features

Main Features

1. Energy-saving ventilation Thanks to efficient recovery of thermal energy lost during Ventilation (load incurred by outside air), you can save an air-conditioning fee.
2. 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.
3. Humidity adjusting effect In a cooling mode, a highly humid openair is brought near to a dehumidified room atmosphere and then supplied. In a heating mode, room humidity is transferred to the dry outside air and then supplied.
4. Comfortable and consistent ventilation Ventilation is available with the least possible fluctuation of room temperature. Since exhaust and air intake are performed simultaneously, stable ventilation is possible even in a highly airtight room.
5. Sound shield effect The ducts of the unit and the heat exchange element are characteristic of the sound shield effect. Thus, it prevents outside noise from coming into the unit and also sound inside the unit from going out, so that the office and store environment can be preserved.

Specific Caution Items

Checking Location of Installation
These Energy Recovery Ventilators have been designed especially for use In offices, and conference rooms. etc. Please check to ensure that neither the main unit nor the inlet-outlet grill is installed in any of the following locations.
Locations exposed to high temperatures or direct flame. Avoid installing the Energy Recovery Ventilators or the inlet-outlet grill in locations that reach temperatures of 40°C or above. Usage under high-temperature conditions may cause distortion of the filter or Heat Exchange Element or motor burn-out.
Locations with high humidity. Do not install in high humidity locations such as bathrooms. Doing so may cause a breakdown of the unit or an electric shock.
Locations with large amounts of oily smoke, such as food preparation areas. The unit will become inoperable if the fitter or Heat Exchange Element becomes clogged with oil.
Make sure that Inspection Opening Is provided so that filter and Heat Exchange Element maintenance and periodic spot checks of the unit can be easily carried out. (Refer to the Model Installation for its space)
Do not install the unit in locations such as machinery or chemical plants where it will be exposed to noxious gases containing acids, alkali, organic solvents, and paint fumes. etc., to gases containing corrosive ingredients, or where dust or oil mist will be produced.
If there are any problems concerning the location or installation of the unit, please consult either store from which it was purchased or the agent who installed it.
When Using
Always be sure to use a filter. Failure to do so may cause dust and dirt to build up on the heat exchange element. lowering its efficiency and rendering it inoperable.
Operate the Energy Recovery Ventilator Remocon with certainty.ln 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.
Never operate the “Normal ventilation” during the winter when the room Is being heated, as this will cause condensation to form inside the unit and in the inlet-outlet vent.

Model Installation

Note that when installing a unit body upside down, its printed indication is in a reversed position.
Method of Use
For detail, please refer to the”Energy Recovery Ventilator Remocon” manual.
