Cabinet Operation
Startup
• The compressor is ready to operate when the unit is purchased.
All you need to do is plug in the cooler.
• Excessive tampering with the control could lead to service
difficulties. If replacing the temperature control is ever needed,
be sure to order the replacement from your TRUE dealer or
recommended service agent.
• Good air flow inside your TRUE unit is critical. Take care to
prevent product from pressing against the sides or back
wall and coming within 4" (101.6 mm) of the evaporator
housing. Refrigerated air off the evaporator coil must circulate
throughout the cabinet for even product temperatures.
NOTE: If the unit is disconnected or shut off, wait 5 minutes
before restarting.
RECOMMENDATION
– Before loading product, run your TRUE
unit empty for 24 hours to verify proper operation. Remember,
our factory warranty DOES NOT cover product loss!
