4. Installation

4.1 Installation Checklist

IMPORTANT: Prior to installation of the UA-135H, the following checklist should be reviewed. The UA-135H 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 devices location.

4.1A Drainage and Trap

Unit should be located in an area where the UA-135H's condensate (water) may be easily routed to a suitable drain. Space and location requirements should take into account the incorporation of a trap for the assembly as shown in section 4.4.

4.1B Filter Box & Fresh Air Ventilation

Unit location should be in an area where the unit’s return (intake) side will be easily accessible for ducting. Ducting the

optional fresh air ventilation to the filter box should be easily accomplished by the unit's location.

4.1C Power Accessibility

Unit should be located in an area where the cord's length (6') should easily reach a 115 VAC electrical outlet with a minimum of a 15 A circuit capacity.

4.1D Space

Location should have enough clearance to handle the unit's overall dimensions as well as the necessary return/supply ductwork to the unit and the additional 4" in height for the unit to drain properly.

The filter box should be accorded enough space to allow for the opening of the filter access panel and for the replacement of the filter elements.

4.1E Low Voltage Wiring

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

4.1F Sound

The UA-135H produces sound levels from 50 to 60 dB. If necessary, do not locate unit in or adjacent to areas which the unit's sound might be aggravating to the end user. For additional noise control, attach 3⁄4" plywood surround.

4.1G Back-Draft Damper

It is recommended that a back draft damper be utilized on the supply ducts for the UA-135H. The unit location should be able to permit this accessory to be installed if requested by the end user. For more information please call customer service at (800) 533-7533.

4.1H Support Structure and Suspension

Place the UA-135H on supports to raise the base of the unit approximately 4" above the horizontal floor below it. Raising the UA-135H will help the unit drain with gravity flow. Do not place the UA-135H directly on structural building members without vibration absorbers or unwanted noise may result.

The UA-135H may be suspended with steel hanger straps (plumbers tape) or a suitable alternative from structural members, as long as the suspending assembly supports the 5 individual feet of the UA- 135H's base in its entirety. 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 External Insulation Kit

An external insulation kit is available for the UA-135H. This will help prevent the cabinet from sweating if the unit is installed in an unconditioned space. This kit will increase the efficiency of the unit by eliminating unwanted heat transfer between the unit and the space. See the optional accessories list for information on the kit.
