Dehumidification

The highly efficient Ultra-Aire 100V dehumidifier utilizes refrigeration to cool the incoming air stream below its dew point. This cooled and drier air is used to pre-cool the incoming air stream resulting in a significant increase in overall efficiency. After the pre-cooling stage, the processed air is reheated by passing through the condenser coil. The heat removed by the evaporator coil is returned to the air stream, resulting in an overall temperature increase of the air leaving the unit.

The Ultra-Aire 100V is controlled by 24 volt remote wired controls. A variety of controls are available suitable to various applications.

Fresh Air Ventilation

Optional fresh outdoor air may be ducted to the unit via a six inch round duct. This provides fresh air to dilute pollutants and maintain high oxygen content in the air. The amount of fresh air ventilation can be regulated by a variety of dampers and controls.

Air Filtration

The UA-100V includes air filtration to improve indoor air quality. A MERV-11 media filter is standard. An optional MERV-14 deep pleated 95% media filter is available for optimum air filtration and to reduce potentially harmful airborne particles. If the optional filter is chosen, the standard filter operates as a prefilter.

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 UltraAire 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

4	Ultra-Aire 100V Installer’s & Owner’s Manual

FOR HVAC INSTALLER ONLY

a separate supply duct from the Ultra-Aire to each isolated area is recommended. DO NOT draw air directly from the kitchen, laundry, or basement. All flexible ducting connected to the Ultra-Aire should be UL listed.

The inlet of the Ultra-Aire is the 8" diameter hole on top of the unit. An 8" round collar is supplied with the unit to attach to round duct. The duct may be permanently attached to the collar. A 6" round collar is provided with the unit to attach to the 6" hole in the top. The 6" collar should be capped if fresh make-up air is not desired. If fresh make-up air is desired see section 3.4C.

The outlet of the Ultra-Aire is located on the side of the unit. A second 8" round collar is supplied with the unit and can be attached using the screws provided and the pre-punched holes in the cabinet side.

A length of 10 feet or more of acoustical flex ducting on the outlet of the Ultra-Aire will reduce air noise from the blower. A length of flexible ducting on all Ultra-Aire duct connections is recommended to reduce noise and vibration transmitted to rigid ductwork in the structure.

Ducting the Ultra-Aire as mentioned in sections 3.4A-3.4G requires consideration of the following points:

Duct Sizing: For total duct lengths up to 25', use a

minimum 8" diameter round or equivalent rectangular. For longer lengths, use a minimum 10" diameter or equivalent. Grills or diffusers on the duct ends must not excessively restrict air flow.

Isolated Areas: Effective dehumidification may require that ducting be branched to isolated, stagnant areas. Use 6" or larger diameter branch ducting to each of two or three areas; use 4" or larger to each of four or more areas.

3.4C Ducting for Fresh Air

Fresh air can be brought into the structure by connecting a duct from outside to the 6" Ultra-Aire inlet and by turning on the fan switch or activating the humidity control on units with the humidity control panel. Activate the ventilation timer on units with the ventilating & humidity control panel to bring in fresh air. Advantages of this form of ventilation include:

1.Outside air is filtered before entering the building.

2.Outside air will be dehumidified before entering if the UltraAire is running.

3.Drawing air from outside and blowing inside aids in slightly pressurizing the structure. This helps prevent unfiltered and undehumidified air from entering elsewhere. It also reduces the potential for carcinogenic radon gas to enter and provides makeup air for open combustion and exhaust devices like the clothes drier, fireplace, and water heater.

4.The need for an alternate ventilation device may be eliminated.

An insulated 6" diameter duct is generally sufficient to provide up

to 125 CFM of outside air. Large quantities of outside air will impact Ultra-Aire performance positively or negatively, depending upon the difference between inside and outside air conditions. Consult the factory by calling 1-800-533-7533 for recommendations regarding the use of higher flows with your specific application.

The outside air duct should be connected to the 6" round collar on top of the unit. The 6" round collar includes a manual damper.

Adjust the manual damper to provide the desired amount of fresh air for ventilation. The amount of fresh air should be based on the size and occupancy of the residence. If you are unsure of your ventilation air requirements, consult the factory by calling 1-800-533-7533 for assistance.

3.4D Installation in a Basement or Crawlspace with an Existing Forced Air HVAC System.

If the structure in which the Ultra-Aire is to be installed has an existing forced air HVAC system, utilize the HVAC system to make the Ultra-Aire installation easier.

If the existing system has multiple returns, select one to disconnect from the existing forced air system and use it for the dedicated Ultra-Aire return. Always select a return from a central location

in the structure in an area that is always open to the rest of the structure. Do not use a return from a room that may have its door closed much of the time.

Basement Installation: Locate a separate return for the Ultra-Aire in a central area of the structure. Duct the supply of the Ultra-Aire to a 8" x 8" x 8" tee/damper that is 30% open to the basement.

Duct the other side of the tee to the air return of the existing HVAC system. If the existing HVAC system has a central return, duct the other side of the tee to the air supply of the existing HVAC system.

5	Ultra-Aire 100V Installer’s & Owner’s Manual

FOR HVAC INSTALLER ONLY

Connect a duct from outside to the 6" collar of the Ultra-Aire if you wish to provide fresh make-up air.

Crawlspace Installation: Locate a separate return for the UltraAire in a central area of the structure. Duct the supply of the Ultra-Aire to a 8" x 8" x 8" tee/damper that is 30% open to the crawlspace. Duct the other side of the tee to the air return of the existing HVAC system. If the existing HVAC system has a central return, duct the other side of the tee to the air supply of the existing HVAC system. Connect a duct from outside to the 6" collar of the Ultra-Aire if you wish to provide fresh make-up air.

3.4E Installation in an Attic with an Existing Forced Air HVAC System

ALWAYS install a catch pan for condensate under the Ultra-Aire in an attic or condensate may drip down on the ceiling of the living space below.

Locate a separate return for the Ultra-Aire in a central area of the structure. Duct the supply of the Ultra-Aire to the air supply of the

existing HVAC system. If the existing HVAC system has a central return, duct the supply of the Ultra-Aire to the air supply of the existing HVAC system. Connect a duct from outside to the 6" collar of the Ultra-Aire if you wish to provide fresh make-up air.

3.4F Installation in a Structure with Two Forced Air HVAC Systems

Attach the Ultra-Aire return to to a independent return from the upper level. Attach the Ultra-Aire supply to the supply of the basement HVAC system. This will promote circulation of air through the whole structure from the upper level to the lower level through the Ultra-Aire . If the Ultra-Aire is not connected to both HVAC systems, it will not control the humidity and ventilation of the entire structure. Connect a duct from outside to the 6" collar of the UltraAire if you wish to provide fresh make-up air.

3.4G Installation in a Structure with No Existing Forced Air HVAC Systems

When installing the Ultra-Aire in a structure that does not have a forced air HVAC system, a single return for the Ultra-Aire should be installed in central open area of the structure. DO NOT locate the return in a bathroom or a kitchen. The supply of the UltraAire should be located in the remote areas of the structure (such as bedrooms, den, etc.). By ducting this way the air inside the structure will circulate through the Ultra-Aire to be filtered and dehumidified. Connect a duct from outside to the 6" collar of the Ultra-Aire if you wish to provide fresh make-up air.

3.5 Quiet Installation

Loosen the compressor mounting bolts from the base of the unit. Do not remove the bolts, but loosen them so the compressor mounting grommets are not compressed. These bolts are tightened at the factory to prevent damage during shipping. Loosening them will reduce the amount of compressor vibration. Make sure none of the compressor tubes are pressed against the cabinet or front panel.

4. Controls

The Ultra-Aire can be equipped with various accessories to enhance its operation. A remote control panel must be used with the Ultra-Aire . There are two remote control panels from which to choose. The humidity/fan control panel is used to control humidity and the fan. The ventilation timer and humidity control panel is used to control ventilation, humidity and the fan.

4.1 Humidity/Fan Control Panel

See Figure 1: The humidity/fan control panel automatically controls the humidity of the living space. The humidity/fan control panel contains an adjustable humidity control and a fan switch. This panel should be mounted in a central area of the structure where it can accurately sense the humidity of the air in the living space. The panel has small perforations that must remain open to the air within the living space for accurate humidity sensing.

The humidity/fan control panel can be used in conjunction with the optional fresh air damper. When used with the optional fresh air damper, the fan/filter switch will act as a fresh air ventilation control. When the switch is ON (in this configuration), the fan will run, the fresh air damper will open, and fresh air will be filtered

and brought into the structure. When the switch is OFF, the fresh air damper will close and the fan will operate only when the humidity control calls for dehumidification.

4.2 Ventilation Timer and Humidity Control Panel

See Figure 2: The ventilation timer and humidity control panel automatically controls both the ventilation and the humidity of the living space. The ventilation timer and humidity control panel contains an adjustable humidity control, a fan switch, and a ventilation timer. This panel will control the humidity and allow


Figure 1:	Figure 2: Ventilation Timer
Humidity/Fan Control Panel	and Humidity Control Panel
Part No. 4024155	Part No. 4024125

programmed ventilation of the living space. This panel works in conjunction with the optional fresh air damper to provide ventilation.

This panel should be mounted in a central area of the structure where it can accurately sense the humidity of the air in the living space. The panel has small slots that must remain open to the air within the living space for accurate humidity sensing.

4.3 Humidity Control Adjustment

Set the humidity control to the desired humidity level for the home. The dehumidifier will run continuously until the relative humidity (RH) is reduced to the humidity control dial setting. Setting the humidity control to lower RH levels will NOT increase the unit's dehumidification rate; the unit will simply run longer to reduce the area's RH to the setting. The Ultra-Aire unit (and refrigerant

based dehumidifiers in general) will reduce a warm space's RH to a lower level than that of a cool space. It is therefore pointless to set the humidity control to excessively low levels in cool rooms; doing so will result in long periods of ineffective dehumidifier run time.

Quality humidity meters are available from the factory and are recommended to accurately monitor humidity levels.

4.4 Fan/Filter Switch

Turning ON the fan/filter switch will cause the central conditioning unit's internal fan to run continuously, whether the central

conditioning unit is dehumidifying or not. This function is desirable if the central conditioning unit is used for air circulation and filtration.

When the switch is ON, air will be constantly filtered through the central conditioning

unit and circulated throughout the house. When the switch is OFF, the fan will operate only when the humidity control calls for

dehumidification or when the ventilation timer calls for ventilation.

4.5 Ventilation Timer

The ventilation timer controls the fan and the motorized fresh air damper. When the ventilation timer is activated, the central

conditioning unit will circulate the indoor air, and bring in fresh air from outside. The ventilation timer should be set for the required ventilation of the residence. The home should be ventilated with fresh air whenever it is occupied.

The ventilation timer is an electronic timer that displays the current time. This timer has a battery backup, so it will not require resetting after a power outage. The one minute time increments of the ventilation timer allow you to program the ventilation of your home to fit your schedule.

The ventilation timer has six programs with each program having one “on” and one “off” event. A program allows the user to turn the ventilation on at a certain day and time, then it allows them to turn the ventilation off at a certain day and time. Each of these programs can be repeated daily or weekly or during a specified block of days. All six of the programs operate independently of each other.

If the timer fails to operate or operates erratically, check that the control panel receives 24Vac from the Ultra-Aire . If 24Vac is

present at the control panel, reset the timer by pressing the reset button at the bottom center of the timer face. The reset button is the small recessed button with an R beneath it located below the 1…7 and h buttons. Press the reset button in until the display disappears. Release the reset button. The display will reappear as 00:00. Resetting the timer will clear the time and all program settings. After resetting the timer, follow the instructions below to set the correct time and ventilation programs.

The following instructions explain how to set the ventilation timer. First, set the correct time on the timer by sliding the switch in the upper right hand corner of the timer to the clock symbol + and pressing the 1…7 (DAY), h (HOUR), and m (MINUTE) buttons. Remember that this timer operates on a 24-hour (military time) clock.

Next, set the ventilation time schedule. Slide the switch in the upper right hand corner to the program symbol P “ON” will appear to the right of the time and the number “1” will appear in the lower right hand corner of the display. The “1” and “ON” signify the turn on time for the first program. Press the 1…7 button to choose

the days of the week for this program. You can choose Mon-Sun Mon-Fri, Sat-Sun, or any single day of the week. The days chosen are shown along the top of the display on the ventilation timer. Next press the h button to set the hour for the start of the ventilation period. Remember that this timer operates on a 24-hour clock. Then press the m button to set the minutes past the hour to start the ventilation. Now, with the ventilation start time set, press the I/O button. The word “OFF” should appear to the right of the time

7	Ultra-Aire 100V Installer’s & Owner’s Manual

FOR HVAC INSTALLER ONLY

and the number “1” should remain in the lower right hand corner of the display. The “1” and “OFF” signify the turn off time for the first program. Set the turn off time using the 1…7, h, and m buttons in the same way as described above and continue on to the second through sixth programs. When setting the ventilation programs, you can return to the current time display by sliding the switch in the upper right corner of the timer to RUN. The slide switch in the upper right must be set to RUN for the timer to operate with the scheduled programs.

The slide switch in the upper left of the timer is used to choose between automatic and manual operation of the timer relay. When the slide switch in the upper left of the timer is set to AUTO mode, the central conditioning unit will ventilate when the scheduled programs call for ventilation. When the slide switch in the upper left of the timer is set to manual (set to hand symbol on the the right), the operation of the timer is controlled by the I/O button only. Pressing the I/O button will switch the ventilation timer between ON (detent) and OFF (detent). As you press the I/O button, “ON” or “OFF” will be displayed to the right of the time. The “ON” or “OFF” to the right of the time will indicate if the ventilation timer is on or off. The I/O button will manually override scheduled programs if the timer is in AUTO mode.

4.6 High Efficiency Air filter

A high efficiency air filter is available for the Ultra-Aire . This filter is rated 90%-95% efficient by ASHRAE Dust Spot Test Method 52-76. This filter is much more efficient than the standard air filter and is able to catch much smaller particles that can aggravate allergies.

The high efficiency air filter is 4 inches thick and should be installed in the filter enclosure directly below the standard air filter. The standard air filter will act as a pre-filter for the high efficiency air filter and will prolong the life of the high efficiency air filter.
