Warranty Information

The company guarantees the product under certain warranty conditions but is not responsible for loss or damage of content.

Introduction

Read these instructions carefully for safe operation. Keep them for future reference. The company is not responsible for safety if used improperly or for unintended purposes. Contents are subject to change.

Precautions for Safe Operation

Follow WARNING and CAUTION signs to prevent injury and damage. Ensure proper ventilation, especially when using CO2 gas. Ground the unit properly. Do not use outdoors or in humid, flammable, or corrosive environments. Disconnect power before maintenance. Do not touch electrical parts with wet hands. Avoid inhaling aerosols. Never splash water on the unit or place liquid containers on it. Do not damage the power cord. Use a dedicated power source. Ensure proper plug connection. Check settings after power failure. Be careful not to tip the unit during movement.

Installation Site

Install in a location protected from direct sunlight, with adequate ventilation (at least 10 cm clearance), away from heat sources, with stable temperature (-5 to +35°C), on a sturdy and level floor, not prone to high humidity, and without flammable or corrosive gases. Avoid locations where objects can fall.

Start-Up of Unit

Ensure all switches are off. Set up the CO2 cylinder (AT type). Shut the door, connect power. Turn on power and battery switches. Set desired chamber temperature (not below -86°C). For AT type, set backup cooling kit activation temperature and switch on CO2 backup. Test alarm and CO2 spout. Put articles into the chamber, temporarily switching off CO2 backup for warm items. The unit resumes operation with previous settings after power failure.

Troubleshooting and error codes

Malfunction Check/Remedy
The chamber is not cooled at all
  • The circuit breaker of power source is active.
  • The voltage is too low. In this case, call an electrician.
  • The power switch is not ON.
  • The large amount of articles (load) is stored in the chamber at one time.
The cooling is poor
  • The ambient temperature is too high.
  • The inner lid is not placed adequately. The door is not closed firmly. (The frost or ice between the cabinet and door gasket possibly prevents door seal.)
  • The air intake vent is blocked.
  • The condenser filter is clogged. Always clean the filter when the filter check lamp is blinks.
  • The set temperature is not inputted properly.
  • The freezer is not away from the direct sunlight.
  • There is any heating source near the freezer.
  • A rubber cap and insulation for the access port are not set correctly.
  • You put too many unfrozen articles into the freezer compartment.
Alarm test key cannot actuate the alarm
  • The alarm is activated only when the power switch is ON.
  • When only the buzzer or only the alarm is actuated by the alarm test key, the unactuated part is out of order, and must be replaced.
Noise
  • The freezer is not installed on the sturdy floor.
  • There is anything touching the frame.
  • The freezer is not leveled with the leveling feet.
  • The freezer is in the status immediately after start up.
  • The unit sometimes causes a noise when the chamber temperature is high due to the large load. The noise gets less and less accompanying with the cooling of the chamber.
Back-up test switch does not operate normally (when the Backup cooling kit is provided)
  • The liquid carbon dioxide tank is empty.
  • The valve of the carbon dioxide tank is not opened.
  • The ambient temperature is too high. In this case, move the tank to a cool location. Inquire at liquid carbon dioxide suppliers about its check, adjustment, installation, or move.
