Thank you for choosing a
Ductless Heat Pump
for your customer.
Please read this installation manual carefully before installing and starting up the Multi21 System. Take a moment to fill out the product and 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.

INSTALLATION SITE INSTRUCTIONS
Indoor Unit
Select a site that allows for the following:
1. Ensure the installation complies with the installation minimum dimensions (defined below) and meets the minimum and maximum connecting piping length and maximum change in elevation as defined in the System Requirements section.
2.
Air inlet and outlet will be clear of obstructions, ensuring proper airflow throughout the room.
3. Condensate can be easily and safely drained.
4. All connections can be easily made to outdoor unit.
5. Indoor unit is out of reach of children.
6.
A mounting structure (i.e. wall, ceiling, floor,...) strong enough to withstand four times the full weight and vibration of the unit.
7. Filter can be easily accessed for cleaning.
8. Leave enough free space to allow access for routine maintenance.
9. Install at least 10 ft. (3 m) away from the antenna of TV set or radio. Operation of the air conditioner may interfere with radio or TV reception in areas where reception is weak. An amplifier may be required for the affected device.
10. Do not install in a laundry room or by a swimming pool due to the corrosive environment.
Minimum Indoor Clearances - High Wall Units
NOTE:
For minimum clearances of other indoor unit types, refer to
the Installation Instructions enclosed with those indoor units.

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 units.
3. Install 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.
