INSTALLATION CONTINUED UNIT LOCATION This FRESH-PAK unit is certified for through-the-wall, indoor, up-flow vertical position installation only. This appliance is not design certified for installation in mobile homes, recreational vehicles, or outdoors. A factory approved wall sleeve must be used to install the FRESH-PAK unit.
INSTALLATION CONTINUED UNIT CLEARANCE REQUIREMENTS WALL SLEEVE INSTALLATION The interior of the unit may be installed with zero clearances to adjacent combustible Refer to installation instruction packed with the wall sleeve surfaces. This furnace shall not be installed directly on carpeting, tile, or other combustible to assemble and mount into the wall.

INSTALLATION CONTINUED WALL SLEEVE INSTALLATION CONTINUED REAR INSTALLATION & DIMENSIONS Sleeve rough-in opening is 44” (H) [111.76cm] x 27-5/8” (W) [70.17cm]. Bottom of opening should be approximately 6” [15.24cm] about the floor. Minimum of 6” [15.24cm] clearance is required on the ERV fresh air (supply air) side.
INSTALLATION CONTINUED PACKAGED UNIT INSTALLATION FIGURE 12 - FRESH-PAK Unit Installation Insulation is installed in indoor equipment to provide a barrier between outside air conditions surrounding the unit and the varying conditions inside the unit. If the insulating barrier is damaged, the surrounding ambient air will affect the inside surface temperature Locate the unit in an area that provides minimum clearance to all service access panels.

INSTALLATION CONTINUED PIPING (HOT WATER COILS) PIPING INSTALLATION: All piping must be adequately sized to meet the design water flow requirements as specified for the specific installation. Piping must be installed in accordance with all applicable codes. Prior to making piping connections, contractor must clean and flush water loop system.
INSTALLATION CONTINUED OUTSIDE DUCTWORK ERV RETURN Discharge ductwork is normally used with these units. When return air ductwork is required, the unit is supplied with 2” [5.08cm] thick filter rack/duct collar for connection of return air ductwork. All ductwork must be installed in accordance with National Fire Protection Assoc.
INSTALLATION CONTINUED CONDENSATE DRAIN AIR FILTER The FRESH-PAK is designed so that the wall sleeve is the principle drain pan. Drain tubing ll indoor return air must be filtered. The preferred methods are: is factory installed which drains evaporator condensate though the bottom of the unit Use the factory supplied filter kit which attaches to the inlet of the evaporator.
ELECTRICAL HIGH VOLTAGE Disconnect all power supplies before servicing. Lock out/tag out to prevent accidental electrical shock. NOTE: There may be multiple power sources supplying the unit. Use copper conductors only. Install all parts and panels before operation of unit. Failure to follow these warnings can result in injury or death.
