5. If cooler is equipped with a white aluminum evaporator (cooling band), loosen (fig.5-1) and
unhook (fig.5-2) the latch and catch from the band and pull the band back away from reservoir to-
wards the back of cooler cabinet. If cooler is equipped with a copper tubing evaporator, there is no
latch system to unhook.
6. Remove faucets by turning counter clockwise (fig.6-1), remove baffle disk (fig.6-2)(fig.6-3).
Mark a vertical line on the outside of the reservoir across evaporator (fig.6-4), so when re-installing
the reservoir will be lined up as it is presently.
7. Hold the evaporator down and press the reservoir up and out of the evaporator cooling coil
(fig.7-1).
At this point it is advisable to put the cooler on a bench or table to make it easier to access compo-
nents.
8. Remove the 4 screws that secure the metal top and bottom plate, 2 on top (fig.8-1) and 2 on
the bottom (the outside screws)(fig.8-2). Leave the 4 screws that hold the black grill to the top &
bottom plate secure.

9. The RRS system is now ready to be slid out of the plastic cabinet.
10. Hold the condenser on the right hand side and slowly lift and pull to free the RRS system from
the cooler body. Slowly work the unit from top to bottom until it starts to slide out. Once it starts
to come out, be careful of the small capillary tube (copper coil) located on the left side of the
compressor as it is very fragile (fig.10-1), guide it by the cooler body with your hand. Then slide
the unit as far as possible to the left and the support stick on the right side will come by the body
(fig.10-2). Continue until the RRS is outside the cooler body and free standing on its own (fig.10-3).
