1. Lift carton off storage cabinet.
(CAUTION: Do not install unit on its shipping pallet!)
2. Move unit to position and adjust leveling legs (23).
(CAUTION: Leveling legs must not be extended more than one (1) inch.)

(NOTE: Once bricks are loaded, the booster can no longer be moved.)
4. Remove sheet metal screws on the lower edge of the cabinet's painted front panel (33).
5. Pull painted front panel (33) out at bottom edge to detach.
6. Remove sheet metal screws around outer edge of the inner galvanized front cover panel (13) and set aside.
7. Carefully lift the three insulation blankets (8, 9, and 10) one at a time and drape them over the top of the unit.
CAUTION: Use face mask, gloves, and long sleeved garments when handling insulation
materials in accordance with generally accepted safety practices.
8. Remove the stainless steel panel (2) by pulling out at the top.
9. Remove heating elements (18) and packing material from core cavity.
10. Load brick (19) one row at a time starting at the lower back working forward
(See Installation Tips under Figure 5).
11. For installation of last middle brick, refer to Figure 4; or, a shim may be used to hold upper brick in place.
12. Insert heating elements (18) between brick layers with cold pins facing up. (See Figure 5 detail).
13. Make heating element (18) connections.
(NOTE: Use two 3/8" wrenches to ensure tight connections and to avoid twisting the threaded ele
ment cold pins.)
(NOTE: The second to last row, front, middle
brick must be the last brick installed.
This is most easily done by leaving the
middle brick in the second to last row
pulled about 4" forward from its in-
tended position. This acts as a support
for the front middle brick of the last (top)
row. When installing the front, middle
brick of the second to last row push brick
in which will at the same time push the
middle brick that was left forward into
place. This procedure is often referred to
as the "Last Brick Trick.") LAST BRICK INSTALLATION
