installation form on the back cover. Retain both the manual and installation

record for future reference.

SAFETY PRECAUTIONS

Please read the following before installation.

This is the safety alert symbol. It is used to alert you to potential

personal injury hazards. Obey all safety messages that follow this

symbol to avoid possible injury or death.

This mark indicates procedures which, if improperly performed,

might lead to the death or serious injury of the user.

This mark indicates procedures which, if improperly performed, might

possibly result in personal harm to the user, or damage to property.

Notice is used to address practices not related to personal injury.

General Safety Precautions

1. Instructions for installation and use of this product are provided by the manufacturer.

For proper operation, the system must be installed in accordance with this

installation manual.

2. Installation must be performed in accordance with local laws, regulations and

National Electrical Codes (NEC).

3. If refrigerant leaks while work is being carried out, ventilate the area. Do not allow

refrigerant to come in contact with a flame as it produces toxic gas.

4. Disconnect all electrical power to the indoor and outdoor units until the system is

ready for start-up and checkout.

5. When installing or repairing the system, use only R410A refrigerant. Do not

mix refrigerant with other gases. If air or other gas enter the refrigeration system,

the pressure inside the system may rise to an abnormally high value and cause

damage or injury.

This appliance is not intended for use by persons (including children) with reduced physical,

sensory or mental capabilities, or lack of experience and knowledge, unless they have been given

supervision or instruction concerning use of the appliance by a person responsible for their safety.

INSTA ATION SITE INSTRUCTIONS

Indoor Unit

The unit must be installed in a location which can withstand four times the weight of the unit.

Inadequate support may result in serious property damage and injuries.

Select a site that allows for the following:

•Ensure the installation complies with the installation minimum dimensions and meets the

minimum and maximum connecting piping length and maximum change in elevation.

• Air inlet and outlet should be clear of obstructions, ensuring proper airflow throughout the room.

• Condensate can be easily and safely drained.

• All connections can be easily made to outdoor unit.

• Indoor unit is out of reach of children.

• A structure strong enough to withstand four (4) times the full weight and vibration of the unit.

• Filter can be easily accessed for cleaning.

• Leave enough free space to allow access for routine maintenance.

• Do not install in a laundry room or by a swimming pool due to chemicals corroding cassette coil.

nstall the outdoor unit at a location that is capable of withstanding twice the weight of the unit.

2. Install the outdoor unit where it is convenient to connect refrigerant lines to the indoor unit.

3. I nstall the outdoor unit where the condensate water can be drained unobstructed during the

heating mode to a safe location.

4. Do not locate the unit where the noise may be objectionable to neighbors.

5. Provide the space shown below, so that the air flow is not blocked and future service and

maintenance can be performed.
