Installation

1. The product should be place on a solid and flat floor with no gradient.
2. The product is recommended to work with under 28℃ ambient temperature and less than 55% relative humidity, where direct sunshine and draught can be avoided. Additionally, disturbing air devices such as fan or air conditioner vent should be appear from its top or nearby.
3.  Unobstructed ventilation should be ensured for condensing unit with ample room for repairing.
4.  The melting water can be directed into the sewer near the product, if any, or otherwise evaporated through electric heating.

Normal operation

1. Full-automation. Fully consider the local seasonal conditions within a year and the surrounding environment are sufficiently considered during the setting of control modules, to ensure the optimal operation of the whole full-automatic product.
2. Normal cooling. Set the temperature controller properly according to customers’ needs to achieve both energy-saving and normal cooling. See the Appendix: Instruction of CAREL Temperature Controller for details.
3.  Normal defrost settings. Set the timer properly for melting time and interval according to the ambient temperature and humidity, with over two melting periods for verification. See the Appendix: Instruction of CAREL Temperature Controller for details.
4. During normal operation, the storage should not be placed beyond the shelf or block the air flow from the air curtain.

 Maintenance and Notes

1. Cabinet cleaning. The product should be cleaned once a week with the power supply disconnected. In cleaning, please use mild rinsing water or non-corrosive cleanser essence. Do not wash it directly with a water faucet.
2.  De-dusting for the condenser. The condenser should be cleaned every three months with the power supply disconnected. To clean the condenser, remove the left panel, and remove the dust on the cooling fin of the condenser with a wire brush or high-pressure air gun.
3. Leaking check. Observe all connectors and welding joints for oil stains, which indicates a must for patching measures or call for professionals.
4. Ensure the smoothness of drainpipes.
5. Frequently observe the operation of the product. In case of any abnormal noise, smell or smog cut off the power supply immediately and call for professionals for help. Do not restart the product before trouble is cleared.
6.  We will not be responsible for any accident incurred by failure of following the notices.
