Installation

Environment

1.Ambient temperature: The Haier 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.

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 damage to property.

2.There should be at least 30 centimeters space all around the unit for good ventilation for heat removal.

3.The location for installation should be flat and firm. 4.There should be good ventilation and no direct sunlight.

5.The freezer unit cannot share the same power socket with another piece of equipment. The power plug should be securely connected with the power socket.

6.The power cord for the freezer should not be twisted or pinched.

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.

9.A proper grounding terminal must be guaranteed.

10.If the power socket is connected with a ground terminal, make sure to inspect it for proper connection before using the equipment with it.

11.If the socket does not have a ground connection, it must be installed by a qualified technician.

Recycle Rechargeable Battery

The Haier freezer is equipped with a rechargeable battery. This battery is recyclable. When the battery reaches the end of its life, please contact a local recycling organization for inspection or properly discard the battery.

1.Location of the battery

The battery in the freezer is for the power outage alarm. It is located inside the control box in the lower left behind the panel.

Warning There are high voltage components in the control box. To prevent electric shock, a qualified technician or engineer should open the cover.

2.Removal of the battery

Turn off the power to the unit and unplug the power cord from the socket.

Use a screwdriver to remove the screws on the side panel and take down the side panel.

Use the screwdriver to remove the cover for the control box.

Remove the bracket that fastens the battery. Remove the battery. Follow regulations to recycle the battery or discard it properly.

Caution

When changing the battery, you must make sure that the brown wire connects to the positive of the battery, and the blue wire connects to the negative of the battery. The polarity must not be reversed. Incorrect polarity can damage the charge board so that it cannot charge the battery.
