10. Push heat exchanger through hole in cabinet (See
figures 3 & 5.) and set evaporator back in place.
11. Slide Armor-Flex over heat exchanger until cover is
against hole at back of cabinet. Excess cap tube
can be wound around suction line.
12. Use Permagum to seal hole on inside and outside.
(See Figues 3 & 5)
13. One piece cover can now be installed over heat
exchanger. Place open end of cover even with top of
compressor compartment opening. Attach cover to
back of cabinet using screws provided. No need to
predrill holes; screws are self cutting. (See Figure 4.)
14. Seal hole and end of old heat exchanger with
Permagum. (See Figure 6.)
15. Replace Drier-Filter.
16. Evacuate and recharge system.
17. Bend remaining tubing to fit into machine
compartment opening; avoid tube contacts that may
cause excess noise from line vibration. (See Figure
7.)
18. Run product to make sure refrigerant is circulating.
19. Reinstall evaporator and machine compartment
cover.

PERIMETER HOT TUBE REPAIR KIT
Effective July 1, 1992, Section 608 of the Clean Air Act
prohibits Individuals from knowingly venting ozone
depleting compounds used as refrigerants into the
atmosphere while maintaining, servicing, repairing, or
disposing of refrigerant equipment.
A hot tube repair kit is used to bypass a leaking
Perimeter Hot Tube (Yoder-Loop). The Perimeter Hot
Tube must be bypassed in the sealed refrigeration
system and a low wattage heater wire installed inside the
tube. This heater will prevent condensation from forming
on the exterior front edge of the cabinet.
Hot Tube Heater Kit Contants:
1 Copper Bypass Tube 1 Plastic Sleeve
1 Drier-Filter 1 Heater Wire
3 Clamps 1 Harness Adapter
3 Screws 2 Wire Connectors
BYPASSING PERIMETER HOT TUBE - STEP 1
1. Disconnect service cord from power supply.
2. Recover refrigerant from system.
3. Remove filter-drier.
4. Use tubing cutter to cut and de-burr tubing from
perimeter hot tube at points shown in figure below.
5. Install copper bypass tube and replacement filter-
dryer as shown in figure below. Use 45% silver
solder for all connections.
6. Drill or pierce three holes in cabinet to hold
clamps. Secure by-pass tube just below cabinet
edge with three clamps and screws provided.
NOTE: When clamped in place, the by-pass tube
should NOT touch any plastic lines, such as
water lines for ice makers and/or filters, as well
as drain lines.
7. Evacuate and recharge refrigeration system. Refer
to serial plate for correct charge.
Cut at filter-drier inlet. Cut at weld between
condenser and hot tube.
