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 twice the weight of the unit.

Inadequate building support at the installation location may result in serious property

damage and injuries.

Review the installation location with the customer as follows:

1. Ceiling is strong enough to support twice the weight of the unit.

2. Ductwork can easily be installed using the shortest amount of duct.

3. Location allows easy installation of drain pipe.

4. Electrical power can easily be run as a dedicated circuit.

5. Space is left around the unit as required in Fig. 1.1 for future service and maintenance.

6. Air inlet and outlet of the unit should never be blocked, so airflow can reach every

corner of the room.

The unit should be installed level on a pad that can support twice the weight of the unit.

If the outdoor unit will be exposed to strong winds, it must be adequately secured.

1. Install 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 in Fig. 1.2, so that the air flow is not blocked and future service and

maintenance can be performed.
