Chapter 2 –Installation
2.1 General Requirements
2.1.1 Location Requirements
Install the unit on a firm and level floor in an indoor environment.
Allow at least 150 mm (6”) of open space on the sides, top and rear.
The location should be sufficiently ventilated so the heat from the unit can be removed from the area
to prevent any potential overheating condition of the ambient temperature.
Avoid installing a unit in an area with direct heat source such as sunlight, heat radiator, and other
heat sources.
CAUTION Do not position the unit in a way that impedes access to the disconnecting device or circuit
breaker in the back of unit.

6
2.1.2 Environmental Requirements
Indoor use
Altitudes of up to 2000 meters (6600’)
Up to 90% relative humidity –non-condensing
Temperature between 15OC - 32OC (59OF - 90OF)
Note: Recommended operating temperature is 25oC (77oF).
Must be installed in a room with sufficient ventilation. The room ventilation should be a technical
ventilation that is in accordance with the requirements of ZH 1/119 (Guidelines for laboratories) or
some other suited ventilation system with appropriate capacity.
2.1.3 Power Requirements
Designed for 230 VAC 50Hz 1Φelectrical rating with maximum current withdrawn of 12 A.
For personal safety and trouble-free operation, this unit must be properly grounded before it is used.
Failure to ground the equipment may cause personal injury or damage to the equipment. Always
conform to the National Electrical Code and local codes. Do not connect the unit to overloaded power
lines.
Installation Category: II
Note: Installation category (over voltage category) defines the level of transient over voltage which the
instrument is designed to withstand safely. It depends on the nature of the electricity supply and its over voltage
protection means. For example, in CAT II, which is the category used for instruments in installations supplied from
a supply comparable to public mains such as hospital and research laboratories and most industrial laboratories,
the expected transient over voltage is 2500 V for a 230 V supply and 1500 V for a 120 V supply.
Performance criteria B in voltage dips & short interruptions immunity test.
Note: During the voltage dips & short interruptions immunity test, flicker of the fluorescent light was observed
when the voltage dips and short interruption were being applied on the AC mains port of the equipment and self-
recovered after the test.
It is recommended that the voltage fluctuation doesn't exceed ±5% of the nominal voltage at all
times. Otherwise, an electrical power stabilizer can be installed.
UPS is recommended for better protection. If UPS is not used and there is a power failure, the
operator must take immediate action to prevent the danger of potential warm-up.
2.2 Installation
2.2.1 Unit Leveling
It is important that the equipment is properly leveled by positioning a bubble level on the middle shelf of the
freezer. The freezer has built in leveling feet for adjustment. To raise a corner with a leveling foot, use a cross
wrench to turn the leveling leg that appears to be in a low position in the counterclockwise direction.

1. Attach the bracket (1) to its place –sync the
hole in the bracket(1) to the hole in the unit
2. Screw the M6 bolts into the designated
places (the holes on top and below the
bracket(1))
3. Repeat steps 1 and 2 with the other
bracket(1)

2.2.4 Remote Alarm Contacts Connection
External alarm can be connected to the remote
alarm terminal located at the back of the freezer
base above the power cord. The alarm is outputted
from this terminal with contact capacity of 30 VDC,
2 A. The contact output is as follows:

Note: The alarm is freezer temperature-driven and only
actuated when the freezer temperature exceeds the high
or low temperature alarm limit.
2.2.5 Electrical Supply Connection and
Power Protection Bracket Installation
Plug the power cord into the power inlet at the rear
of the unit. Turn on the power switch. Install the
power protection bracket over the power cord and
power switch by installing the 3 screws into the pre-
tapped holes.

2.3 First Run (Also required whenever the freezer is turned off or moved)
Before activating the unit for the first time, ensure that there’s no object other than the shelves inside the
freezer.
Turn on the power switch. The controller will light up. The first stage compressor will get the power and start
working after the initial time delay has passed. When the heat exchanger inside the freezer becomes cold
enough and reaches a predetermined temperature, the second stage compressor starts. The unit continues to
operate until it reaches the set temperature.
Scancool Classic Ultra-low Temperature freezers have an operating temperature of -40 °C to -86 °C. The
freezer is shipped from the factory with a temperature set point of -80 °C. Refer to section 3.4 to change
temperature setting.
The Scancool Classic Ultra-low Temperature Freezer has a battery switch located behind the right bottom
door.
Once the unit reaches set point temperature, open the outer and the inner doors to load in half of the racks.
In the process of doing so, the freezer temperature is expected to warm up. Let the unit recover to the set
temperature then load in the rest of the racks.
If the freezer does not require any racks, let the unit run at set point for at least 48 hours for observation
before placing any products inside the unit.
Note: Samples/articles should be put into the freezer chamber in a small batch to prevent excessively high temperature
rise inside the freezer.
2.4 Disclaimer
The performance and safety of the freezer, while rigorously evaluated at the factory, cannot be guaranteed
after transit and installation. Therefore, on-site testing is always recommended.
Battery switch
Battery switch should always be turned on when the unit
runs. This will enable the board to stand by and the power
failure alarm to beep when there is an AC power outage.
Warning: Make sure the scheduled maintenance for the battery
is carried out; refer to chapter 4, to ensure the battery stays
charged when the unit is on).
Warning:When this product operates at the first start-up or
after not being in use for a long period, the built-in battery
capacity may be lowered or completely zero due to self-discharge
of the battery. The low battery alarm may be activated. Let the
freezer operate on AC power for more than a day (24 hours) to
charge the battery.
