Therma-Stor Products Group UA-150H - Manual (Page 4)

1. Intended Application for Ultra-Aire 150H
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 UA-150H can be installed in a variety of locations to meet
the owner's needs as listed below. In all cases keep the following
cautions in mind:
• It is designed to be installed INDOORS IN A SPACE THAT IS
PROTECTED FROM RAIN AND FLOODING.
• Install the unit with space to access the front panel for
maintenance and service. Also allow easy access to the filter cover
panel. DO NOT INSTALL UNIT WITH THE FRONT PANEL OR FILTER
COVER PANEL INACCESSIBLE.
• Avoid discharging the air directly at people, or over the water in
pool areas.
• If used near a pool or spa, be certain there is NO chance the unit
could fall into the water or be splashed and that it is plugged into a
GROUND FAULT INTERRUPTER.
• DO NOT use the UA-150H as a bench or table.
• DO NOT place the UA-150H directly on structural members.
• A drain pan MUST be placed under the unit if installed above a
living area or above an area where water leakage could cause
damage.
Place the UA-150H on supports that raise the base of the unit
above the top of the flanges on the drain pan beneath it. Raising the
UA-150H will help the unit drain with gravity flow. Do not place the
UA-150H directly on structural building members without vibration
absorbers or unwanted noise may result.
The UA-150H may be suspended with steel hanger straps (plumbers
tape) or a suitable alternative from structural members. Remember
to place a drain pan under the unit if it is suspended above a finished
area or above an area where water leakage could cause damage.
The UA-150H should be located near the existing air handling
system to minimize the required ductwork for connecting the
UA-150H to the existing air handling system. The controls for the
UA-150H 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 UA-150H with low voltage thermostat
cable.
An external insulation kit is available for the UA-150H. This will
prevent the cabinet from sweating if the unit is installed in an
unconditioned space. This kit will also increase the efficiency of the
unit by eliminating unwanted heat transfer between the unit and the
unconditioned space. See the optional parts list for information on
the kit.
If fresh air ventilation is desired, thought should be given to the
location for the fresh air ducting. A 6” round insulated duct will
have to be installed on the UA-150H and run to the outside of the
structure to bring in fresh air. Use an 8” insulated round duct for
lengths of more than 50 feet or if more than 100 CFM is needed.
Consult local codes for necessary distances from exhaust ports
when installing fresh air return.
3.2 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-150H plugs into a common grounded outlet on a 15 or
20 Amp circuit. It draws around 12 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.
Install the remote control panel in a central area of the structure
where it will sense the relative humidity of the structure accurately.
Do not install the control panel where it may not accurately sense
the relative humidity such as near HVAC supply registers, near
exterior doors, or near a pool or spa. The installer must supply the
wiring between the UA-150H and the control panel. Be sure to safely
route the control wiring to prevent damage during installation. Be
