USER MANUAL DEEP FREEZERS
1. General information
This manual describes the performance, usage and handling precautions of the purchased product.
Please read carefully before using the product.
1-1. Introduction
This product supports fast cooling speed and minimal power consumption by applying
the innovative cooling system Simplified Hi-Efficiency Freezing System.
It was developed and manufactured in consideration of convenience and safety in use,
and has the following features.
1. Simplified Hi-Effciency Freezing System for high efficiency and safety simplifies the structure and
electrical circuit to minimize the time to reach the target temperature and the amount of power consumption.
2. Two independent cooling structures maintain cooling temperature even if one system has a problem
and have a perfect Back Up function (Only Dual Comp. Type).
3. The operation of various menus has been simplified through the 7-inch full-touch screen.
4. Urethane insulation, internal door insulation, and 3-layer insulation are installed to prevent cold air leakage
and intrusion of external temperature and maximize the insulation effect.
5. By adopting an automatic vacuum canceling device, the pressure difference between
the inside and outside is automatically resolved, making it easy for the user to open the door
6. It is easy to operate by adopting a solid and ergonomic door handle,
and a locking function is installed for security.
7. Data can be checked with a high-resolution graphic display,
and data backup and program update are possible through the USB port.
8. The LCO2 spray function is supported to prevent damage to the sample
in case of sudden device shutdown (OPTION).
9. Through Eco Mode, the user selects the cross operation cycle of the compressor arbitrarily
to support power saving operation (Only Dual Comp. Type).
10. Filter-Free Mechanism that structure does not require a filter, and management such as replacement
or cleaning of the filter is omitted, providing the user with management convenience.

2. Installation
2-1. Installation
1. Be careful when transporting the product as it is heavy.
2. Do not put the product on its side or subject it to impact. Internal damage may occur.
3. This product is designed to operate normally at the rated voltage,
so check the voltage status before installing the product.
4. Install in a place with low heat and humidity. Heat such as direct sunlight weakens the cooling power,
and when it comes into contact with moisture or water, the insulation will deteriorate.
5. If there is no regular distance from the wall of the installation space, cooling power will weaken
and power will be wasted. Install it at least 15cm from the rear wall and at least 10cm from the side wall,
and use it at least 100cm from the ceiling.
6. The power plug of this product is a plug with grounding. Be sure to connect to an outlet with ground.
Incomplete grounding may cause electric shock.
7. If there is no grounding, grounding work by an electric construction company is required.
Do not connect the ground wire to the water pipe and gas pipe (the risk of explosion or ignition),
and the grounding or lightning rod (danger of lightning) of the telephone line.
8. To prevent damage to the door during product transportation, a bracket is installed on the top of the product,
so be sure to remove it before opening the product door.
