TSG Lab Refrigerators and Freezers

Incorrect positioning can cause damage to the machine and create dangerous conditions for users; therefore, the installer must comply with the following general rules: 

• Position the machine keeping a minimum distance of 100 mm from all walls. If the machine is embedded in any type of furniture, a correct air flow of the condensing unit (compressor/fan motors) must be always ensured. The warranty will immediately expire, if this is not guaranteed.

Set the machine in a sufficiently ventilated environment.

• Place the machine far from heat sources and far from sources of electromagnetic interferences (such as motors, generators, infrared beams, telephones) which can have negative effects on equipment functioning.
• Avoid exposure to direct sunlight and air conditioning flows.
• Remove the supplied accessories and the wooden pallet base.
• Position the machine with the aid of a spirit level.

Equipment is shipped already cleaned. However it is advised to carry out a further washing following the instructions below:

• Remove the protective PVC film from the external surfaces of the machine.
• Clean the inside of the chamber with a cloth dampened with alcohol in order to eliminate the protective oil.

CAUTION: The glass door must be cleaned using a cloth dampened with water. Do not therefore use chemicals.

The electrical system and connection must be set up by qualified personnel. Follow the instructions below for safety reasons: 

• Make sure that the system is suitably sized for the absorbed power of the machine.
• It is essential to properly connect the machine to an effective grounding system set in accordance with current legislation.
• In the event of incompatibility between the outlet and machine plug, replace the outlet with a suitable type, provided that the part is approved according to the laws in force.
• If electrical cable is damaged, it must be replaced by qualified personnel to prevent any risk.
• If the freezer is supplied without a plug, connect it directly under the switch board.
• Do not interpose adapters and/or reducers.

ThermoFisher Scientific devices are equipped with 2 safety fuses (phase and neutral) with integral protection against electric shocks, short circuits and over-currents, and according to the standards for laboratory devices.

Before turning on the appliance, it is necessary to check that it has not been damaged during transport, handling and installation.

• Check the condition of the packing (it must not show dents and/or breakages).
• Check the condition of the external frame (it must not show dents and/or breakages).
• Check the condition of the power cord (it should not have scratches or cuts).
• Check that the wheels are stable.
• Check that door opens correctly and closes hermetically.
• Check door gaskets (they should not have scratches or cuts).
• Check that display do not show cracks.

The stainless-steel rack system allows for the installation of shelves.

Do not remove safety protections without having switched off the refrigerator cabinet and disconnecting it from the electrical mains. 

The manufacturer disclaims all liability that may arise if this regulation is not observed.

We recommend cleaning both inside and outside surfaces of the unit at least twice a year. Disconnect the power cord before any cleaning.

The following is indicated for this purpose:

• Cleaning products: Water and non-abrasive neutral detergents. Do not use solvents or thinners.
• Cleaning method: Use a cloth or sponge soaked in a suitable cleaning product to clean the inside and outside parts of the cabinet.
• Disinfection: Do not use substances that can alter the organoleptic characteristics of stored products.
• Rinsing: Use a cloth or sponge soaked in water. Do not use water jets.
• Frequency: At least twice a year or at different intervals depending on the type products stored.

Failure to clean the condenser, as well as temperature being too high in the environment in which it is installed, is one of the main causes of difficult cabinet operation. Cleaning must be carried out every 2-3 months, even in the cleanest environments. You must access the condenser coil, placed in all models in the technical compartment near the compressor, and clean it with one of the following: 

• Long bristle brush
• Vacuum cleaner
• Compressed air

CAUTION: Do not use metal brushes. Do not bend condenser fins. Also, always disconnect the power cord before this operation. 

In order to ensure optimal unit operation, follow the manufacturer instructions, arranging for periodic maintenance to be carried out by qualified technicians.

Follow these below cleaning instructions according to the bought model: 

1. TSG400R & TSG400F
   • PHASE 1: Use a Phillips head screwdriver to remove the guard (3 screws).
   • PHASE 2: Use a vacuum cleaner, air jet, or a long bristle brush to remove any dust on the condenser fins. Perform this procedure backwards to restore correct fastening of the guard.
   • PHASE 3: Restore the electrical current and switch back on the device.
2. Model TSG700R,TSG1500R,TSG700F & TSG1500F
   • PHASE 1: In models with higher motors (7001500L), the condenser can be accessed directly from the outside using a ladder.
   • PHASE 2: Use a vacuum cleaner, air jet, or a long bristle brush to remove any dust on the condenser fins.
   • PHASE 3: Restore the electrical current and switch back on the device.

Defrost causes the formation of condensate water. The water evaporates automatically in models with motor compartment in lower position. 

To ensure maximum efficiency, we suggest periodically changing backup batteries at least every 2 years. This operation can be performed by users, easily accessing the housing located. 

• At the rear of the device
• At the upper of the device (models with upper motor compartment)

1. Cause: Controller Set to "Stand-By."
   • Solution: Switch on the controller.
2. Cause: No mains.
   • Solution: Check the plug, outlet, fuses, and electrical line.
3. Cause: Power plug not connected to the electrical outlet.
   • Solution: Connect the power cord to the electrical socket.
4. Cause: Control panel fault.
   • Solution: Contact Technical Support.

1. Cause: Too much material has been placed in the compartment.
   • Solution: Reduce the quantity and leave space between the shelves and walls. Place products in the cabinet a few at a time after the temperature has stabilized.
2. Cause: Material was placed in the freezer area at room temperature.
   • Solution: Store only already frozen products.
3. Cause: Prolonged or too frequent door openings.
   • Solution: Reduce door openings and close the door more quickly.
4. Cause: Ambient temperature is too high.
   • Solution: Air condition the environment.
5. Cause: Condenser clogged by dust or dirt.
   • Solution: Clean the condenser.
6. Cause: Electronic controller operating fault.
   • Solution: Contact technical support.
7. Cause: Cooling system operating fault.
   • Solution: Contact technical support.

1. Cause: Unit Instability.
   • Solution: Eliminate the cause.
2. Cause: Contact with objects (e.g. cardboards, polystyrene or other materials).
   • Solution: Move and/or remove objects touching the equipment. 

Cause: Unit has detected an alarm.

Solution: Visualize alarms.

1. Cause: Formation of ice in the evaporator or sudden defrosting.
   • Solution: Contact Technical Support.
2. Cause: Humidity level in the environment.
   • Solution: Air condition or ventilate the environment.
