All work must be done according to local and national building, electrical and mechanical codes. Wear proper safety equipment when performing your Installation . Get local permits if necessary. Do not adjust or handle refrigerant unless you are EPA-Certified. Do not handle high-voltage electrical wiring unless properly trained. Be careful when handling sheet metal - it can be very sharp. Improper Installation of products or improperly servicing a furnace can cause serious injury or death.

Some things to keep in mind: Ground needs to be level and secure. Keep unit out of constant, directsunlight, if possible. It will run moreefficiently in the shade. Unit should not be positioned directlyunder a gutter or where excessive watercould pour down on it. Rain won t hurtthe unit, but it s best to keep it fromneedlessly getting wet. Unit should be close to electrical circuitpanel in home for an easier wiring run. Unit should not be placed too closely toplants. The unit needs clearance aroundit for adequate airflow. For cosmetic reasons, the unit should beplaced in an area that is slightly hiddenfrom direct view of home. Unit must be three feet away from a gasor electric meter.

7 Cut Opening on Supply Plenum to Mount Coil Within ItObjective: Cut opening in side of supply plenum (located on top of your furnace) to mount evaporator coil - (800) 865-59311011Go To and carefully discard the rectangle you cut out of the supply Sheet Metal Shelves to Hold Evaporator Coil Inside PlenumObjective: Build sheet metal shelves inside supply plenum so that evaporator coil can sit centered inside plenum. Four sheet metal shelves are supplied with your supplies package. Each is larger than what you will need and are designed to be cut to size to fit your exact : Trim the shelves so that they fit inside the plenum, but do not block airflow into bottom of coil. This is what the coil will look like sitting on top of the sheet metal shelves. This will all be mounted inside the supply : The shelves should be cut narrowly enough that the full coil opening is exposed to the air stream beneath it, but not so narrowly that the coil does not have enough of a base to sit on.

8 This photograph shows the bottom of the coil and how far over the sheet metal should reach. Objective: To ensure that water runs forward to the drain hole in the plastic tray on the bottom of the coil, the back shelf should be positioned 1/2 higher than the front shelf. This will create a 1/2 forward pitch on the coil and will allow water (which collects as water condenses on the cold evaporator coil) to drain out of the plastic - (800) 865-59311213Go To IndexThe dimensions in the diagram are for example purposes ONLY.

You are ready to installyour line set. Skip the following a Raised Sheet Metal CoverIf the coil sticks out beyond the plenum opening (excluding the refrigerant lines) you will need to build a raised sheet metal do this, first measure the numberof inches the coil sticks out beyond theplenum from the center of the suctionline (this is the refrigerant line near topof coil that sticks out the furthest) to theplenum opening, on all four sides.
