4. Installation

4.1 Installation Checklist

IMPORTANT

Prior to installation of the UA-90H, the following checklist should be reviewed. The UA-90H can be installed in a variety of locations to meet the owner’s needs, and integrate with existing forced air systems or existing ductwork if desired. The location choice is contingent on a variety of requirements not limited to: ease

of service, controls access, drainage, filtration, power, fresh-air ventilation, water damage prevention, and current regulatory codes (ASHRAE, fire, etc). Please address all of these issues before you select the device’s location.

n4.1A Power Accessibility

Unit should be located in an area where the cord’s length (10’) should easily reach a 115 VAC electrical outlet with a minimum of a 15 A circuit capacity.

n4.1B Space

Location should have enough clearance to handle the unit’s overall dimensions as well as the necessary return/supply ductwork to the unit.

n4.1C Low Voltage Wiring

Unit location should be in an area where field wiring the remote controls (low voltage) to the unit will be possible.

n4.1D Back-Draft Damper

It is recommended that a back draft damper be used in the discharge duct of the UA-90H, especially when connecting to the supply ducting system. The backdraft damper prevents supply air from counter flowing through the UA-90H when it is not operating. The unit location should be chosen to allow installation of this accessory if requested by the end user.

n4.1E Support Structure and Suspension

Place the UA-90H on supports to raise the base of the unit. Do not place the UA-90H directly on structural building members without vibration absorbers or unwanted noise may result.

The UA-90H may be suspended with steel hanger straps (plumbers tape) or a suitable alternative from structural members, as long as the suspending assembly supports the UA-90H’s base in its entirety. Do not hang the UA-90H from the cabinet. 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.

4.2 Electrical Requirements

WARNING

WARNING: DO NOT ALLOW THE YELLOW LEAD FROM THE ULTRA-AIRE TO CONTACT THE RED LEAD FROM THE ULTRA-AIRE OR DAMAGE TO THE TRANSFORMER WILL RESULT.

The UA-90H plugs into a common grounded 115VAC outlet. The device draws 6.3 Amps under normal operating conditions. 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-90H. 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-90H with low voltage wire (thermostat or other appropriate).
