FOR HVAC INSTALLER ONLY

4.3 Electrical Requirements

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.

The UA-135H plugs into a common grounded 115VAC outlet. The device draws around 11.4 Amps under normal operating conditions. Note, the unit may trip the current of a 15A circuit, if the circuit contains other heavy electrical loads. If used in an area which may become wet, a ground fault interrupter (GFI) protected circuit is recommended. Please, consult local electrical codes for any further information.

Therma-Stor LLC offers a family of control devices for use with the UA-135H. The controls are to be located remotely from the unit and located in the space to be conditioned. The controls are low voltage (24 volt) and should be connected to the UA-135H with low voltage wire (thermostat or other appropriate).

Do not install the control panel where it may not accurately sense the relative humidity such as near HVAC supply registers, near exterior doors, on an outside wall, near a window, or near a water source.

The installer must supply the wiring between the UA-135H and the control panel. Be sure to safely route the control wiring to prevent damage during installation.

Do not cross wires when connecting the UA-135H and the remote control panel or damage to the transformer may result. The remote controls of the UA-135H are powered by a low voltage circuit (24VAC) and must NEVER contact or be connected to a high voltage circuit.

The control wires leaving the UA-135H and the remote control panels are numbered and color-coded to prevent confusion. Some of the control wires leaving the UA-135H 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 inside the access panel of the UA-135H before making control connections.

4.4 Condensate (Water) Removal

IMPORTANT: Incorporate a trap for the assembly as shown in Figure 2. Use care to keep the pipe assembly as flat to the floor as possible, kinks and/or humps will prevent proper drainage.

The Ultra-Aire APD generates condensate. Condensate drains by gravity via the 1" x 3⁄4" bushing extending from the unit. It is necessary to assemble your own drain pipe assembly utilizing 3⁄4" PVC pipe to get the condensate to a floor or other drain. Pipe is commonly available in 10'

lengths from building supply, plumbing or hardware stores. Grade of pitch should be 1" per 10'.

4.4A Lifting Condensate

An optional condensate pump kit may be installed if a lift is required to dispose of the condensate. The condensate pump can be ordered direct from the factory. See the optional parts list in Section 7 for information on the kit.

4.5 Ducting

4.5A Installing Duct Collars

The UA-135H is equipped with 10" diameter round inlet and exhaust collars. The inlet collar is factory installed. The inlet collar is designed with tabs that fold inside the 10" hole located on the return panel of the UA-135H.

To install the exhaust collar, bend all four tabs out and away from the center of the collar. The exhaust collar is attached to the UA-135H by fastening the four tabs on the outside of the supply panel to the UA-135H. Fasten the collar to the supply panel of the

UA-135H by removing one fan screw, placing the collar over the four holes, then screwing the fan screw and three additional #10-24 thread cutting screws into the four holes near the 8" diameter outlet hole.

4.5B 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 UA-135H into the supply of the existing heating system. If the existing heating system incorporates a central supply, installation of a separate supply duct from the UA-135H to each isolated area is recommended.

4.5C Fresh Air / Supply Air

IMPORTANT: DO NOT draw air directly from the kitchen, laundry, or isolated basement.

You may draw air from a basement that is open to the home. All flexible ducting connected to the UA-135H should be UL listed.

A length of 6 feet or more of flex ducting on the outlet of the UA- 135H will reduce air noise from the impeller fan. A length of flexible ducting on all UA-135H duct connections is recommended to reduce noise and vibration transmitted to rigid ductwork in the structure. Ducting the UA-135H as mentioned requires consideration of the following points:
