WARNING Before serving or installing this equipment. The electrical power to this unit must be in the “off” position. Caution, more than one disconnect may exist. Failure to observe this warning may result in an electrical shock that can cause personal injury or death.

WARNING

The United States Environmental Protection Agency (“EPA”) has issued various regulations regarding the introduction and disposal of refrigerants introduced into this unit. Failure to follow these regulations may harm the environment and can lead to the imposition of substantial fines. These regulations may vary due to the passage of laws. A certified technician must perform the installation and service of this product. Should questions arise, contact your local EPA office.

WARNING
Due to high system pressure and electrical shock in potential, installation and service work can be dangerous. Only trained and qualified persons are permitted to install or service this equipment. Observe all warnings contained in this manual and labels/tags attached to the equipment.

WARNING
This product is factory shipped for use with a 208/230V-1Ph-60Hz electrical power supply. This air handler must not be reconfigured to operate with any other power supply.

WARNING
The unit must have an uninterrupted, unbroken electric grounding to minimize the possibility of personal injury if an electric fault occurs. The electric grounding circuit may consist of an appropriate-sized power cord which connected with the
grounding piece located in the unit control box and also connects to the building’s electric service panel. Other methods of grounding are permitted if performed in accordance with the “National Electric Code* (NEC/ “American National Standards Institute” (ANSI “National Fire Protection Association” (NFPA) 70 and local/state codes. In Canada, electric grounding conforms to the Canadian electric code CA c22.1. failure to observe this warning can result in electrical shock that can cause personal injury.

• Special warning for installation of furnaces or air handling units in enclosed areas, such as garages, utility rooms or parking areas.
• Carbon monoxide-producing devices (such as an automobile, space heater, gas water heater, etc.) should not be operated in enclosed areas such as unventilated garages, utility rooms or parking areas because of the danger of carbon monoxide (CO) poisoning resulting from the exhaust emissions. If a furnace or air handler is installed in an enclosed area such as a garage, utility room or parking area and a carbon monoxide-producing device is operated therein, there must be adequate ventilation directly to outside.
• This ventilation is necessary to avoid the danger of CO poisoning which can occur if a carbon monoxide-producing device continues to operate in the enclosed area. Carbon monoxide emission can be (re)circulated throughout the building if the furnace or air handler is operating in any mode.
• CO can cause serious illness including permanent brain damage or death.

Installation

Unit Inspection

Upon delivery, inspect the unit for damage. Any damage must be reported immediately to the carrier. Do not install such an equipment damaged by freightwhich determines the integrity and safety of the unit.
Please check the equipment model number to ensure the unit is appropriately sized for the condensing unit.
If an incorrect unit is supplied, it must not be installed and it is to be returned to the supplier. The manufacturer assumes no responsibility for the installation of incorrectly delivered units. The evaporator coil comes pre- chargedwith .55 lbs (8.8 oz) of R410A gas

Location

WARNING This air handler is designed for indoor installation only. Do not install outdoors

• When installing the air handler, take consideration to minimize the length of refrigerant tubing as much as possible. Do not install the air handler in a location either above or below the condenser that violates the instructions provided with the condenser.
• Service clearance is to take precedence. Allow a minimum of 24″ in front of the unit for service clearance. When installing in an area directly over a finished ceiling (such as an attic), an emergency drain pan is required directly under the unit.
• See local and state codes for requirements. When installing this unit in an area that may become wet, elevate the unit with a sturdy, non-porous material. In installations that may lead to physical damage (i.e. a garage) it is advised to install a protective barer to prevent such damage.
• This air handler is designed for a complete supply and return ductwork system.
• Do not operate this product without all ductwork attached.
• Based upon the actual conditions, if air handler is installed as Fig. A or Fig. B make sure that there is enough space for care and maintenance and the air handler is not accessible to the general public.

Piping Work

• Specification of Connection Pipe
• Piping Preparation
• Solder Connection
• All cut ends are to be round, burr free, and cleaned. Failure to follow this practice increases the chances for retrigerant leakage.

Screw Connection

Condensate Removal

• Do not connect the condensate drain pipe into sewer pipe or other pipelines which are likely to produce corrosive or bad odors to prevent the smell from entering indoors and/or corroding the unit.
• Do not connect the condensate drain pipe to any rain drainage pipe to prevent rain water from backing up and causing property loss or personal injury.
• Condensate drain pipe should be connected into dedicated drain system forthe air conditioner.
• The drain pan has primary and secondary drain connections. Condensate removal is performed by attaching a 3/4* PVC pipe to the evaporator coil pan and terminated in accordance with local or state Plumbing/HVAC codes. The installation must include a “p° style trap that is located close to the evaporator coil. Do not over-tighten the drain connection to prevent possible damage to the evaporator drain pan. See the following figure for details of a typical condensate line “P” trap.

Ductwork
This air handler is designed for a complete supply and return ductwork system.

WARNING

• Do not operate the unit without all ductwork attached and completed. Inadequate ductwork restricts airflow and can result in improper performance and compressor or heater failure.
• Ductwork is to be constructed in a manner that limits restrictions and maintains suitable air velocity. Ductwork is to be sealed to the unit in a manner to prevent air leakage and infiltration.
• Return ductwork: Do not terminate the return ductwork in an area that can introduce toxic or objectionable fumes/odors into the ductwork. The return ductwork is to be introduced into the air handler bottom (up flow configuration). Return Air Filters: each installation must include a return air filter. This filter may be installed at the air handler or externally such as a return air filter grille.

Electric Heater

The air handlers listed in this manual do not have factory installed electric heat.
Electric heat is available as an accessory. Please refer to installation instructions provided with heater kit for the correct installation procedure.
WARNING Refer to the “installing electric heater” section of this manual and the instructions provided with the heater kit for the correct installation procedure.
WARNING The electrical characteristics of the air handler, the electric heater kit, and the supply power should be identical. This air handler does not have factory installed electric heater. Electric heater is available as an accessory. If installing this option, the only heater kits that can be used are the series as indicated below.
