1 Foam Gasket For Top Edge of Bin 2’ x 3/4” x 1/4”
1 Tube Silicone Sealant Black used to seal base/bulkhead insulation
1 Tube Silicone Sealant White used to seal front edge of vacuum-formed base
1 Mylar Strip 8” x 21 1/2”
Additional materials required: Caulk gun, 2” x 4” wood blocks, and wire ties.
Preparation
1. Disconnect power from ice machine.
2. Remove front, top, and side panels.
3. Drain water from sump trough.
4. Ice machine must be thoroughly dried before the insulation can be installed. Use towels to dry bulkhead and base assembly.
Base Insulation Installation
1. Raise the ice machine above the bin. A high lift can be used, or (two people required) lift front edge of ice machine and place
wood blocks (2”x 4”) between ice machine and bin. Lifting one side of ice machine at a time, move wood blocks to center
balance point of ice machine.
2. Slide vacuum-formed base insulation assembly between the ice machine and bin. Align the insulation with the back and sides
of the bin and ice machine.
3. Add one layer of foam tape insulation from the front of the bin to the front of the base insulation on the left and right side.
4. Raise front of ice machine and position the wood blocks on edge (3 1/2” height). This will allow the top of the vacuum-
formed base to be accessed.

3. Add foam tape both sides.
2. Install vacuum-formed base insulation
and align back and sides.

5. Place two beads of black silicone sealant (1” in from the edge) on the front and both sides of the vacuum-formed base.
6. Remove wood blocks and lower the ice machine onto the vacuum-formed base (check side and back alignment). Push the
center of the vacuum-formed base tight to the ice machine base. Secure the vacuum-formed base to the ice machine water
trough with tape. Remove tape after silicone sealant has set.
7. Seal the front edge of the base insulation to the bin with white silicone sealant.
Install Mylar Strip between Evaporator and Bulkhead
Mylar will cover the joint where the bulkhead attaches to the base. It will extend from the left sidewall past the water inlet fitting.
1. Remove screws (right and left side) that secure the evaporator to the bulkhead.
2. Determine bin switch wire location and cut a slot in the top edge of the mylar strip (adhesive edge = top).
3. Apply silicone sealant at the bin switch wire entrance and the left side corner (4” each direction) where the base and bulkhead
meet.
4. Pull evaporator away from bulkhead. Place bottom of mylar strip in sump trough and slip up behind evaporator (align slot cut
in step 3 with bin switch wire). Mylar must extend above bottom evaporator mounting screw (approximately 2” above
gasket/bulkhead joint).
5. Remove paper backing from mylar. Apply tension to mylar to eliminate wrinkles.
6. Align evaporator extrusion and bulkhead screw holes; puncture mylar for the bottom screw holes and insert screws. Install all
remaining evaporator screws.
7. Puncture mylar and insert screws removed in step 2.
Bulkhead and Sidewall Insulation
1. Using the supplied insulation as a template, cut and remove the fiberglass insulation (approximately 9” from base to top of
cut). Using a putty knife, scrape insulation and glue from the bottom of the bulkhead on the rear and both sides.
2. Remove upper white backing to expose tape surface (do not remove backing below slit at bottom). Slide the insulation down
into the base and then press the insulation against the bulkhead to secure. Insulation must bottom out on the base and be tight
to the fiberglass insulation.
3. Repeat step 2 on the left side bulkhead.
4. The back panel insulation will rest in a bed of silicone. Apply a continuos bead of black silicone sealant to the base of the ice
machine next to the bulkhead wall.
5. Peel the white backing off of the insulation for the back bulkhead (9” x 21 1/2”). Align the slots in the insulation with the
ridges in the base. Press the insulation against the bulkhead to secure. The insulation will overlap the left and right side
insulation installed earlier. Ensure that the foam and fiberglass insulation mates flush with no voids.
6. Peel the white backing off of the 3” x 21 1/2” strip of insulation and install over the bottom section of the 9” x 21 1/2”
insulation installed in step 5. Align cut slots with the back bulkhead insulation and press to seal.

Insulation must extend all the way
into the base.

7. Use black silicone sealant to seal insulation to the base, foam insulation to foam insulation joints, and any voids where
insulation meets or overlaps. Add bulkhead corner insulation covers where the rear bulkhead and side panel corners meet.
8. Verify no moisture is present in the suction line tubing. If moisture is present, drain and dry the insulation and reinstall
following step 10 instructions.
9. Install armaflex insulation over the existing insulation on suction line. Use 3/4” x 3/8” insulation on the evaporator outlet and
inlet tubing and 2” x 3/8” on the rest of the suction line. Use suitable glue to seal insulation airtight (do not use electrical
tape). Seal the ends of the insulation with wire ties.
10. Remove clear vinyl tube from dump valve and brass wing adapter. Install armaflex insulation over tube and then reinstall
tube to dump valve and adapter. Ensure white clamps are secure to prevent water from leaking.

7. Seal insulation to base with silicone sealant
5. Align insulation slits with base ribbing
10. Insulate drain line
4. Apply bead of silicone before applying insulation
9. Install additional insulation on entire suction
line
