How to correctly distinguish whether the cold storage installation is qualified?

First of all: enter the construction site, verify the construction situation according to the construction drawing, determine the installation location of the equipment (the storage body, drainage door, evaporator, main engine, condenser, control system, etc.).

Floor installation:

First level the floor, then start to install the floor, select the beautiful floor in a conspicuous place, and do the floor and evaporator drainage system.

Floor requirements:

The floor is installed flat, the floor is flattened with materials, and the hook between the plate and the plate is locked to achieve a flat surface and no hollow feeling. (Note that if the drainage system is installed outside the north, the drainage pipe needs to be insulated).

Vertical board installation:

According to the site conditions, first select a corner, and locate (ie, the vertical plate and the floor lock) extend to the two sides at this angle, only lock the vertical plate and the vertical plate, and locate the vertical angle, the beautiful plate is placed in the conspicuous position. At the point of installation on the side of the evaporator, the drain pipe is prepared in advance, and the U-bend and silicone are required outside the warehouse.

Vertical board requirements:

The vertical surface of the vertical plate is flat, the storage plate has no concave points, the head surface of the vertical plate is flush, the gap between the vertical plate and the vertical plate is even, and the prominent angle is flush with the floor angle.

Celestial installation

First select a positioning gusset and extend the laying, the locking between the celestial and the celestial, and the conspicuous one and the vertical slab in the installation are guaranteed to be flat and locked to prevent the movement.

Celestial requirements:

In the conspicuous place, the sky plate is made of beautiful sky, the seam between the sky and the vertical plate should be flush, the gap is small, and the sky plate in the library is flat. After the sky, the ground and the vertical board are generally installed, the sky and the vertical, the vertical and the floor are corrected and locked, and all the hooks are locked.

Remarks: When encountering a library plate that needs to be flared, the flaring needs to be ground and free of burrs. When encountering a library plate that needs to pull the aluminum, the silica gel is pulled and the aluminum is pulled to ensure the sealing. After the library is installed, the time is required to play silica gel. The silicone seam is smooth and smooth. The silicone zui is arranged in the same day to prevent the damage.

Cold storage electrical installation safety

1. The power supply line for cold storage should be a dedicated branch circuit, and its capacity should be greater than 1.5 times the large current value of the system.

2. It is forbidden to ground the line without grounding or at the specified position; otherwise, the body casing will be charged with static electricity or even electric leakage, which will endanger personal safety; the yellow-green double-color line can only be used as a grounding wire and cannot be used for other purposes.

3. The power cable or control cable should be strictly connected with the crimping card (wire clamp). Otherwise, it will cause looseness and sparking and off-line, leaving hidden dangers. How to correctly distinguish whether the cold storage installation is qualified?

4. It is strictly forbidden to use non-standard power cords; all special lines of cold storage should be equipped with line protection devices such as air switch or leakage protection. Otherwise, fire may occur due to heat generated by plugs, sockets and wires; if there is no corresponding air switch Or the leakage protection switch will not prevent short-circuit or electric leakage accidents caused by equipment failure or accident, and it is impossible to disconnect the power supply in time, which may cause fire and personal injury.

5. It is forbidden to add the power cable or the indoor and outdoor connection cables when the cable is not long enough. The entire wire must be replaced. There is no joint in the middle. Otherwise, the contact may be poor or the heat may not be met due to the lengthening of the part. , causing fire or electric leakage, endangering personal safety. When the connecting line is too long, it is strictly prohibited to be wound into small circles to avoid eddy current heating.

6. It is strictly forbidden to replace the fuse (wire) with copper wire or wire. After the fuse is blown, it should be replaced with the same type of fuse (wire); otherwise the fuse (wire) will not work, the circuit board will lose its protection, and it will easily damage the chip and other. Components, even burned out the board.

7. The indoor and outdoor electrical connections of the cold storage should be unaffected by tensile and torsional stresses; otherwise, short circuits or equipment failures and leakage accidents caused by the power supply line may occur.

8. After the repair is completed, the system must be fully inspected for electrical safety to eliminate hidden dangers, including loose or aging of the terminal or cable connector, and whether the metal cover has a stuck wire.
