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.
