Technical FAQs

• Can I lay the unit down to transport it?

  No, the only way a cooler or freezer should be transported is upright.

• Does 115v/208-230v mean my unit will work for either voltage?

  No, this does not mean this is a dual-voltage unit that can run on either voltage. Please Contact Us for additional information.

• How can I obtain a wiring diagram?

  Please Contact Us for information on a wiring diagram. You must include the cabinet serial number.

• How can I tell if the condenser is clean or dirty?

  Other than looking at the condenser surface, you should also use a flashlight and shine this on the surface to see if you can see all the way through the coil.

• How long should I stand the unit up after it has been laid down?

  Double the amount of time it is not upright unless this is for 4 hours or more. Then it should sit for 24 hours before turning on. For example – if the unit is on its side or back for 15 minutes, it should sit upright for 30 minutes before turning on. Warning - Coolers or freezers should only be laid down when moving them into place. No cabinet should ever be transported on its side or back.

• How old is my unit?

  To determine the age of the unit, enter the serial number in the Serial Number Lookup.

• If the cord on my unit is not long enough, can I use an extension cord or replace the power supply cord with a longer one?

  No. You should never use an extension cord; it would void the cabinet warranty.

• What is the cut-in and cut-out for my temperature control?

  Please refer to the Sequence of Operations manual here.

• What is the recommended setting for temperature control? What numbers are colder and warmer?

  Refer to your owner’s or owner’s manual on the website for control settings in the operation section under the heading mechanical control sequence of operation. The lower the number on a cabinet with a knob from 0 to 9, the warmer the setting. 0 is off.

• What are the refrigerant type and charge of my unit?

  Please Contact Us for information on the refrigerant type and charge. You must include the cabinet serial number.

• What temp is my cooler/freezer supposed to maintain?

  This information can be found on the website on the specification sheet.

• Why does True require a dedicated circuit for freezers or coolers?

  This is to prevent low voltage to the compressor.
