Installation
Installation environment
•
Ambient temperature:10℃ to 32℃ .The ideal temperature is 18℃ to 25℃ . If necessary, use an air-
conditioning system to achieve the required ambient condition.
•
Ambient humidity: less than 80%. At an environment of 32°C, humidity should be less than 57% RH.
•
The intended location should be low in dust count.
•
The intended location should be vibration and shock free.
•
The highest elevation the unit can work safely: 2000 m above sea level.
•
Input voltage: within Rated Voltage ±10 % .
• Overvoltage category: The transient state is Category II facility.
• Pollution Degree:2.
• An ULT freezer is usually sensitive to its operating environment. If a unit is not
Caution
installed in the conditions mentioned above, it cannot operate reliably. Please improve
the environmental conditions before using the equipment.
• It is prohibited to use the unit in an outdoor place. After the unit is rained on, there is
a danger of electric shock.
Installation site
For the equipment to achieve optimal operating conditions, an intended installation location should
satisfy the following requirements.
• Do not install the unit in a confi ned place. The doorway should be large enough for the unit to freely
enter or exit the room if necessary. This is to allow the unit to be repaired easily and timely to avoid
damage to property.
• The location for installation should be fl at and fi rm.
• There should be good ventilation and no direct sunlight.
• The freezer unit cannot share the same power socket with other equipment. The power plug should
be securely connected with the power socket.
• The power cord for the freezer should not be twisted or pinched.
• If the power cord needs to be extended. the cross-section of the extended cable must be no less
than 2 mm² and no longer than 3 m.
• Before using the freezer, check the voltage supply. A voltage stabilizer to deliver rated voltage ±10%
is recommended for areas where the voltage is known to be unstable. The voltage stabilizer should
be rated at least 4000W.
• The freezer must be securely grounded.
• If the power socket is connected with a ground terminal, make sure to inspect it for proper
connection before using the equipment.
• If the socket is not grounded, it must be connected to a grounded terminal by a qualifi ed technician.
• Do not ground the freezer through gas lines, water mains, telephone lines and
Warning
lightning rods as this may lead to electric shock.
• After installation, the power plug must be easy to reach. In case of emergency, it is
easy to unplug. Nothing should block the ventilation port of the freezer.
