Therma-Stor Products Group Ultra-Aire 100V For Hvac Installer Only, Specifications, Installation

FOR HVAC INSTALLER ONLY

1. Intended Application for Ultra-Aire 100V

For the ideal installation, draw air from the central part of the home and return it to isolated areas of the home like the bedrooms, den, utility room, or family room. The ductwork of the existing heating system can be used to supply air to the home.

3. Installation

3.1 Location

The Ultra-Aire should be located near the existing air handling system to minimize the required ductwork for connecting the Ultra-Aire to the existing air handling system.The controls for the Ultra-Aire are remote from the unit and must be located in the space that is to be conditioned. The controls are low voltage (24 volt) and should be connected to the Ultra-Aire with low voltage thermostat cable.

If fresh air ventilation is desired, thought should be given to the location for the fresh air ducting. A 6" round duct will have to be installed on the Ultra-Aire and run to the outside of the structure to bring in fresh air. Use an 8" insulated round duct for lengths of more than 25' or if more than 100 CFM is needed.

3.2 Electrical Requirements

The Ultra-Aire plugs into a common grounded outlet on a 15 Amp circuit. It draws between 6 and 7 Amps under normal operating conditions. If used in a wet area (pool, spa room, or basement prone to flooding), a ground fault interrupter protected circuit is required.

The installer must supply the wiring between the Ultra-Aire and the control panel. Be sure to safely route the control wires to prevent damage during installation. Be careful not to cross the wires when connecting the Ultra-Aire and the remote control panel or damage to the transformer may result.

The remote controls of the Ultra-Aire are powered by a low voltage circuit (24 Vac) and must NEVER contact or be connected to a high voltage circuit. The control wires leaving the Ultra-Aire and the remote control panels are color coded to prevent confusion. Some of

the control wires leaving the Ultra-Aire may not be used with certain control panels and should be left safely disconnected with wire nuts taped onto the stripped ends. Be sure to consult the electrical schematic in this manual or on the front panel of the Ultra-Aire before making the control connections.

WARNING: Do not allow the yellow lead from the Ultra- Aire to contact the red lead or orange lead from the Ultra-Aire or damage to the transformer will result.

NOTE: Reset the ventilation timer before attempting to program after initial installation. The timer may not .. operate correctly until it is reset.

3.3 Condensate Removal

Condensate drains by gravity via the clear hose extending from the unit. Route the hose to a floor drain. Use care to keep the hose as flat to the floor as possible; excessive humps will prevent proper drainage. We do not call for a trap since there is an internal trap with this unit.

If the Ultra-Aire is located too far from a floor drain for the attached hose to reach, inexpensive 1⁄2" PVC pipe can be used to extend it. It is commonly available in 10' lengths from building supply, plumbing and hardware stores. It will slide tightly inside the end of the drain hose.

If more than one length of pipe is required, they can be joined with a short piece cut from the end of the drain hose.

An optional condensate pump may be installed if a lift is required to dispose of the condensate. The condensate pump kit can be ordered direct from the factory. See item 27 on page 21.

3.4 Ducting

3.4A Installing Duct Collars

The Ultra-Aire is equipped with 8" and 6" round inlet collars and an 8" round white exhaust collar. The 8" and 6" round inlet collars are designed with tabs that fold under the top of the Ultra-Aire . The 8" round white exhaust collar is attached to the Ultra-Aire by (4) screws.

To install the inlet collars: Insert the tabs of the collar into the hole in the top of the Ultra-Aire and fold the tabs up to attach to the Ultra-Aire .

To install the exhaust collar: Bend the (4) tabs toward the inside of the collar 90°. Attach the collar to the Ultra-Aire cabinet using 1⁄2" long #8 sheet metal screws. DO NOT use screws longer than 1⁄2" to attach this collar or damage to the refrigeration system may result.

3.4B Ducting for Dehumidification

For the ideal installation, draw air from the central part of the home and return it to the isolated areas of the home like the bedrooms, den, utility room, or family room. The ductwork of the existing heating system can be used to supply air to the home. If the existing supply goes to isolated areas of the home, discharge the supply of the Ultra-Aire into the supply of the existing heating system. If the existing heating system incorporates a central supply, installation of
