The device and operation of the turquoise freezer 14

Operation manual for household freezer MSH-120 "Biryusa-14". The good old Soviet freezer, for some grandmothers it continues to work properly, because they used to do quality things. Quality control department workers, although they received bribes, controlled the quality! What has changed? Either now they simply don’t make quality things, or the quality bar has been lowered, they say, anyway, everywhere is full of cheap Chinese shit, and if you do it with high quality, it will be expensive and no one will buy it.

Even then, they tried to make freezers more comfortable to use, making it possible to rehang the door to the opposite opening, signaling operating modes and adjusting the door opening angle limit. Biryusa is a silver freezer! Only about 2 grams of silver is contained in the contacts of the start-up relay and in the sensor of the temperature relay. If you hand over the household freezer MSH-120 "Biryusa-14" for scrap, then about 4 kg of aluminum will come out. Can the Chinese afford this?

The freezer is not made with a ground wire, so follow the instructions carefully instructions for use. Do not turn on the refrigerator if there is damage to the cord or plug in the power supply. If you feel a tingling sensation when touching the freezer, unplug the power cord immediately and contact your technician for troubleshooting. Do not operate the freezer in areas with high humidity or conductive floors. Household freezer MSH-120 "Biryusa-14" is made in a convenient floor-standing cabinet, which will simplify its operation in the household. The internal volume is divided into compartments.

°°What pleases in the old instruction books for use must have been fundamental electrical circuits. After you brought it from the store, the freezer should be prepared for successful operation, namely, you need to unscrew the transport bolts and screw the adjusting screws in their place, which is described in detail in the user manual. It is recommended to place the freezer away from heat sources and direct sunlight. Although this appliance is a freezer and is designed to generate cold, when transported in the winter season, it must be kept at room temperature with the door open for at least 8 hours before being turned on. If this is not done, then when the cold freezer is turned on, the compressor may jam.

Yes, it turns out that the text of modern user instructions differs significantly from the old ones. instruction manuals. Here is what is written in this old book on the use of the freezer: “Re-hanging is done by the mechanic of the Rembyttekhnika association for a fee.” How cute photoloid!

There are three lights on the case: green, indicating the inclusion of the freezer in the network and red, indicating an increase in temperature in the refrigerator chamber, orange lights up when the freezer is switched to the maximum freezing mode. After 24 hours of operation at maximum freezing, it is recommended to switch the regulator to the “storage” mode.

If your electricity was turned off, it is recommended not to open the door of the MSH-120 Biryusa-14 household freezer, the cold did not come out and the heat did not get inside. Not a long time without work for the products is not scary, they will not have time to melt. Avoid excessive ice buildup on evaporators by removing all food and defrost the freezer. If this is not done, then energy consumption will increase and at the same time the cooling effect will decrease, such a paradox. Defrosting will proceed faster if you put several dishes with hot water in the refrigerator and close the door of the freezer of the household MSh-120 Biryusa-14. Do not try to remove the formed ice on the evaporator with metal objects, otherwise you will make a hole in the evaporator and freezer kirdyk! If the freezer makes rattling sounds during operation, then the reason may be in the wrong installation (not level) or where the pipes touch the refrigerator body.
In stagnant times, this freezer was given a 3 year warranty! In the event of a breakdown, the freezer could be replaced with a new one within those three years. As I wrote above, there are probably several such models that continue to work to this day.

Refrigeration equipment under the Biryusa brand has been manufactured at Krasnoyarsk Plant OJSC since 1963. This enterprise has not sunk into oblivion along with the ruins of the USSR, but continues to work properly. Already 9 years after the launch, the company offered users about 35 models of refrigerators. Even in the 90s, when most enterprises could not stand the collapse of the USSR, the plant in Krasnoyarsk worked and the team received awards for their work. The secret of success in proper organization production, that is, the company tries not to depend on suppliers, this is called vertical integration.

In 1997, the management decided to buy compressor production equipment from the Japanese, which was the right decision. As a result, the company not only paid back the costs, but also began to make a profit from sales. Think for yourself, a Soviet refrigerator with Japanese filling, that is, cheap and cheerful (high quality). The plant now not only provides itself with compressors made on Japanese equipment, but also sells them to other enterprises.

Today, the Biryusa plant produces refrigeration equipment not only for the home, but also for offices, taking into account the peculiarities of operation. Most of the materials are imported, only 15% are domestic, but even this part is made on equipment from Korea, Italy, Germany and, of course, Japan. In terms of production in Russia, this enterprise is in 2nd place.

At the end operating instructions for the freezer "Biryusa-14" there is a page with a suggestion to leave feedback on the operation of the freezer after the warranty period. Freezer turquoise 14 (msh 120) download instructions.

Freezer Biryusa 14 E-2 (MSh 120) is an excellent choice. It can be used both as a home refrigerator and as a freezer in enterprises. Catering(cafe, outlets and etc.).

The company "Biryusa" is known on Russian market for quite a long time and has established itself as a reliable manufacturer of equipment of this class of high quality.

This model has compact dimensions - its height is 85 cm, width is 58 cm, and depth is 62 cm, so it will easily fit into the interior of any room.

The freezer has three freezer compartments equipped with doors and one drawer compartment. Overall volume freezer is 120 liters. The freezing capacity is 9.5 kg/day.

The possibility of autonomous cold storage is very useful, which will help save food from spoilage in case of various unforeseen circumstances. In this model, this time is 12 hours. Energy class - B.

The freezer is made in the form of a floor cabinet, inside which there is a chamber with tanks 1 and 2 (Fig. 1.) for food storage. In the upper part of the chamber there is a compartment 3 for quick freezing of products. The freezer is cooled by the evaporator, which, in the process of boiling in its circulating refrigerant channels, removes heat from the air of the freezer and the placed products. The freezer has two modes of operation: "Freezing" and "Storage".

The operation of the freezer is controlled by a control and signaling unit built into table 4 and a thermostat mounted on the rear wall of the cabinet. The control and signaling unit includes an operating mode switch 6 with illumination (orange lamp) and two indicator lamps 7 (green) and 8 (red). There is also an information plate 5.

The Biryusa-14 freezer is made on the basis of the Biryusa-12 refrigerator and differs from it mainly in the increased thickness of the thermal insulation of the cabinet and door walls, the design of the refrigeration unit (Fig. 2), the thermostat, the presence of an alarm unit and electrical wiring.

When the freezer is switched on, the green and red lamps built into the edge of the table light up. The green lamp indicates that power is supplied to the freezer and is constantly lit, while the red lamp indicates that elevated temperature in the freezer compartment and goes out when the desired temperature is reached.

There is a quick freeze switch on the edge of the table that can be set to Freeze or Store. When the switch is set to the "Freeze" position, the orange lamp lights up, the freezer operates continuously at the minimum temperature. When the switch is set to the "Storage" position, the orange lamp goes out and the freezer is switched to cyclic operation.

The temperature necessary to ensure the safety of frozen products is maintained automatically by a temperature sensor-switch with a constant setting. The freezer operation mode is designed for continuous operation of the motor-compressor during freezing.

The electrical diagram of the freezer is shown in fig. 3.
