Precautions for Safety

WARNING

General

• Carefully read Owner’s Manual before starting the Air to Air Heat Exchanger with DX Coil Unit. There are many 

important things to keep in mind for daily operation.

• Ask for installation to be performed by the dealer or a professional. Only a qualified installer (*1) is able to install an 

Air to Air Heat Exchanger with DX Coil Unit. If a non-qualified person installs an Air to Air Heat Exchanger with DX 
Coil Unit, it may result in problems such as fire, electric shock, injury, water leakage, noise and vibration.

• Do not expose your body to cool air directly for a long time and do not cool yourself excessively.

Doing so may result in deteriorated physical condition and ill health.

• Consult the shop where you purchased Air to Air Heat Exchanger with DX Coil Unit if Air to Air Heat Exchanger with 

DX Coil Unit (cooling and heating) is not performed properly as a refrigerant leakage may be the cause. Confirm the 
repair details with a qualified service person(*1) when the repair includes additional charging of the refrigerant.

• The refrigerant used for Toshiba air conditioner is safe.
• Usually, the refrigerant does not leak. If it should leak and catch fire on a fan heater, stove, or gas range, a toxic 

gas will be produced.

• Install a circuit breaker that meets the specifications in the installation manual and the stipulations in the local 

regulations and laws.

• Do not wash the Air to Air Heat Exchanger with DX Coil Unit. Doing so may result in electric shock.
• When the Air to Air Heat Exchanger with DX Coil Unit is operated with a combustion appliance in the same place, be 

careful of ventilation to let fresh air enter the room. Poor ventilation causes oxygen shortage.

• Be sure to stop running the air conditioner and turn off the breaker before cleaning.

Otherwise, injury may result as the fan is rotating at high speed inside the unit.

• Wear protective gloves and safety work clothing during installation, servicing and removal.
• Use of a stand more than 50 cm high to clean the filter of the Air to Air Heat Exchanger with DX Coil Unit or to carry 

out other such jobs constitutes working at heights. Due to the danger of falling off the stand and injuring yourself while 
working at heights, this kind of work should not be done by unqualified individuals. When this kind of work must be 
carried out, do not do it yourself but ask a qualified installer (*1) or a qualified service person (*1) to do it for you.

• Do not place any combustion appliance in a place where it is directly exposed to the wind of Air to Air Heat Exchanger 

with DX Coil Unit, otherwise it may cause imperfect combustion.

Transportation and storage

• Transport it by the truck or the forklift. Transport it by six people or more when the person transports it temporarily. 

The waist etc. might be hurt when not following it.

• When transporting the Air to Air Heat Exchanger with DX Coil Unit, wear shoes with protective toe caps, protective 

gloves, and other protective clothing.

• When transporting the Air to Air Heat Exchanger with DX Coil Unit, do not take hold of the bands around the packing 

carton. You may injure yourself if the bands should break.

• When stacking the packing cartons for storage or transportation, read the precautions written on the packing cartons. 

Failure to heed the precautions may cause the stack to collapse.

• You shall ensure that the Air to Air Heat Exchanger with DX Coil Unit is transported in stable condition. If you find any 

part of the product broken, contact your dealer.

Installation

• Only a qualified installer(*1) or qualified service person(*1) is allowed to carry out the electrical work of the Air to Air 

Heat Exchanger with DX Coil Unit. Under no circumstances must this work be done by an unqualified individual since 
failure to carry out the work properly may result in electric shocks and/or electrical leaks.

• After the installation work has been completed, have the installer explain about the circuit breaker positions. In the 

event that trouble has occurred in the Air to Air Heat Exchanger with DX Coil Unit, set the circuit breaker to the OFF 
position, and contact a service person. (*1)

• If you install the unit in a small room, take appropriate measures to prevent the refrigerant from exceeding the limit 

concentration even if it leaks. Consult the dealer from whom you purchased the air conditioner when you implement 
the measures. Accumulation of highly concentrated refrigerant may cause an oxygen deficiency accident.

• Do not install the Air to Air Heat Exchanger with DX Coil Unit in a location that may be subject to a risk of expire to a 

combustible gas. If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.

• Be sure to use the company-specified products for the separately purchased parts. Use of non-specified products 

may result in fire, electric shock, water leakage, etc. Have the installation performed by a professional.

• Confirm that earthing is performed correctly.
