42S UNITS — A factory tag is on top of each unit. Tag states riser tier number, floor, room number if furnished and supply- air arrangement. Check unit for any other labels that apply to installation. Remove unit from pallet and take directly to assigned space for installation. Great care must be taken to assure that no force or pressure be applied to the coil, risers or piping during handling. Never use the riser to lift the unit. To maintain the straight and square cabinet alignment, avoid lift- ing or supporting the cabinet only at the top and bottom.

1.Begin on lowest floor and progress upward, floor by floor, to top.

2.Examine drain line (Fig. 28-34). Be sure both ends are in place and that it forms a trap. Avoid pinching drain line.

3.Tip unit over riser hole in building floor. As unit is righted, align riser with unit below.

NOTE: The unit must be lowered into the space taking care to properly align the risers to engage the riser swaged section on the unit below. The riser should never be bent or pushed together to be passed through the floor slot and should never be lifted up or pulled down to meet the riser on the floor below or above.

4.Install isolator pads beneath the four corners of unit if applicable.

5.Before anchoring the equipment in place, the unit must be leveled and the cabinet must be squared and brought into line with any adjacent or included walls. The unit may be anchored in place by bolting directly through the unit floor or attaching to the cabinet in some location that will not interfere with drywall or other items such as the sup- ply grille, thermostat, or return access panel. When at- taching to the unit cabinet, care must be taken to not pen- etrate the cabinet in locations that may damage internal components or wiring. The mounting technique is a mat- ter of choice; however, the unit should always be an- chored securely to prevent movement during construction and riser expansion and contraction. On certain units, shipping screws or braces must be removed after the unit is installed. Be sure to check all tags on the unit to deter- mine which, if any, of these devices need to be removed.

6.If installing a 42SJ unit, follow Steps a-h. For all other 42S units, continue to Step 7.

NOTE: The 42SJ back-to-back fan coils have been de- signed to serve two separate rooms. These products are classified by Underwriters Laboratories Inc. for use in penetration firestop systems, control number 27WL when ordered with 1-hr rated chase. See UL Fire Resistance Directory for more information. Figure 37 shows the 42SJ unit with standard risers and with Siamese risers.

a.Lay out the control lines for the drywall track and studs in the floor and ceiling (see Fig. 38).

NOTE: Tracking may be installed now or after the unit is set.

b.Position the 42SJ fan coil assembly between two rooms with the unit drywall separation spotted over the wall control lines.

c.If not already installed, install the floor and ceiling tracks up to and over the 42SJ fan coil unit.

d.Position the vertical studs and fasten into each of the stud pockets formed into the chase side panels (see Fig. 38).

NOTE: The studs may be mechanically fastened to the 42SJ fan coil. Care should be taken, how- ever, not to penetrate the supply or return water risers or internal piping. Given the levelness of the floor and/or the fan coil assembly, some shimming may be necessary.

e.Assemble the specified wall construction up to and over the top of the fan coil unit (see Fig. 39).

f.With the fire-wall separation being complete, the drywall skin on the surface of the individual fan coils can be applied. Drywall can be applied directly to the surface, or, if necessary, studding may be installed on the corners for vertical control (see Fig. 39).

g.For ease of installation of the access panel, apply drywall on the return air side directly to the sur- face of the unit (see Fig. 39). When applying the wall board directly to the unit cabinet, it may be necessary to shim the wall board in some areas to achieve the desired finished wall surface.
