Pre-Installation
2. Cover the entire unit with a canvas tarp only. Do not use clear, black or plastic tarps as they may
cause excessive moisture condensation and equipment damage.
Installation Preparation
Before installing the unit, consider the following unit location recommendations to ensure proper
unit operation.
1. Clearances: Allow adequate service and code clearances as recommended in “Service Access”
(the next section). Position the unit and skid assembly in its final location.
2. Structural support: Ensure the structural support is strong enough to adequately support the
un
it. The installer is responsible for supply support rods for installation of ceiling units.
3. Level: Verify the floor or foundation
is level. Shim or repair as necessary. To ensure proper unit
operation, install the unit level (zero tolerance) in both horizontal axes. Failure to level the unit
properly can result in condensate management problems, such as standing water inside the
unit.
4. Condensate line & piping: Consider coil piping and condensate drain requirements. Verify
con
densate line is continuously pitched 1 inch per 10 feet of condensate line run to adequately
drain condensate.
5. Wall & ceiling openings: Vertical recessed/concealed
units require wall/ceiling openings. Refer
to submittal for specific dimensions before attempting to install. Horizontal recessed/concealed
units must meet the requirements of the National Fire Protection Association (NFPA) Standard
90A or 90B concerning the use of concealed ceiling spaces as return air plenums. Refer to the
submittal for specific dimensions of ceiling openings.
6. Exterior: Touch up painted panels if necessary. If panels need paint, sanding is not necessary.
Howeve
r, clean the surface of any oil, grease, or dirt residue so the paint will adhere. Purchase
factory approved touch up epoxy paint from your local Trane Service Parts Center and apply.
Service Access
Service access is available from the front on vertical units and from the bottom on horizontal units.
Cabinet and recessed units have removable front or bottom panels to allow access into the unit.
See Figure 2, p. 13 for recommended service and operating clearances.
