Installation
Environment
1.Ambient temperature: The ULT is designed to operate between 5 to 28
.The maximum ambient temperature is 32 . For best results, the operating
ambient should be in between 18 to 25 . If necessary, use an air-conditioning
system to achieve the required ambient condition.
2.Relative humidity in environment: At a normal temperature, the maximum relative
humidity should be less than 80 percent. At an environment of 32 , the maximum
relative humidity is 57 percent.

3.The intended location should be low in dust count.
4.The intended location should be vibration and shock free.
5.The highest elevation the unit can work safely in is 2,000 meters from sea level.
6.Input voltage should be within 220 or 120 VAC 10 .
Notes: 1. An ultra low temperature freezer is usually sensitive to its operating
environment. If a unit is installed outside the conditions mentioned above, it cannot
operate reliably. Please improve the environmental conditions before using the
equipment.
2. It is prohibited to use the unit in an outdoor place. After the unit is rained on, there
is a danger of electric shock.
Location for installation
For the equipment in order to achieve an optimal operation condition, an intended
installation location should satisfy the following requirements.
7.If there is a need to extend the power cord, the extension should be rated for 220
VAC at 16 A and 120 VAC at 20A .
8.Before using the freezer, check the voltage supply. A voltage stabilizer to deliver 220
or 120 VAC ±10 percent is recommended for areas where the voltage is known to be
unstable. The voltage stabilizer should be rated at least 4 kilowatts.
1.Do not install the unit in a room where there is little room to work on the unit should
there be a malfunction. The doorway should be large enough for the unit to freely
enter or exit the room if necessary. This is to allow the unit be repaired easily to avoid
