matters needing attention:
The box is suitable for use in a ventilated, dry, flat, and non corrosive environment, and is suitable for use in air-conditioned rooms.
After the box is in place, it needs to be stationary for a period of time before it can be powered on. A voltage regulator must be configured, and the wiring should be left,<zero>right,<item>and effectively grounded. The compressor should be stopped and restarted at least 3 minutes apart. The power cord should be separately protected from the laboratory distribution panel for equipment use to avoid instrument crashes that may affect operation.
The water level of the water tray should be controlled at 40-50mm, and after placing the specimen, its water level should exceed the specimen by 5-15mm while avoiding uneven water temperature and overflow after the water level is too high.
Users should place the test specimens into the water tray according to the number of specimens made each day for easy removal. At the same time, the water tray should be filled with water for the next day's use of the test specimens. After adding normal temperature water, the test specimens must be placed after more than 10 hours.
It is recommended to control the water level in the temperature measuring water box within 50-60mm. Generally, it should not be opened, but the water level must be checked once within ten days. When the water level is low, please add constant temperature water (water in the water pan without a test machine) to the box to avoid affecting the temperature measurement effect and accuracy.

Fault:
The instrument does not display or work.
The power supply is not connected, whether the zero, phase, and ground positions on the socket are reversed, and whether the plug is in good contact with the socket.
Check if the function switch is in good condition and if the work light is on. First, check if there is power at both ends, otherwise replace the switch.
Check whether the input and output lines of the instrument are loose or have poor contact. The inspection method starts from the power supply wiring and runs along the line once.
The instrument can display but does not work (the indicator light is not on) to check if the air temperature exceeds the limit. When the temperature returns to within the control range, it can resume operation.
If the instrument can display but the display is abnormal, please unplug the power and it will resume normal operation after two minutes. This indicates that the instrument has crashed. It should be checked whether a stable voltage power supply is configured or whether there are high-power devices (such as air conditioners and motors) on the same line. Otherwise, they should be separately wired from the distribution panel for use.
When the device is not in use, please drain the water from the pool and open the box to dry for future use.

Introduction:
According to the requirements of the new standards GB/T17671-1999 and ISO679-1989, and with the guidance of the Cement Institute and Cement Quality Inspection Center of the National Building Materials Research Institute, our company has designed and developed a new generation of constant temperature water curing boxes for cement specimens. In order to meet the needs of different users, a series of products such as 32B, 64B, and 80B are specially produced to ensure the stability of the specimens.

Parameters:
Power supply: 220V ± 10%.
■ Box dimensions: 520 * 450 * 880mm.
■ Capacity: Soft training trial mold 40 * 40 * 160 can hold 32 sets.
Constant temperature water temperature: adjustable from 20 ℃± 1 ℃.
Cooling power: 165W.
Heating power: 300W.
Fan: 45W.
Weight: 120Kg.

usage method:
After the box is in place, connect the 220V stabilized power line and ground wire. (The maintenance box should be placed horizontally) Add 4-5CM of water to each pool, and ensure that the tap water is clean. Then close the box door.
■ Place the switch completely in the OFF position, and once everything is normal, connect the 220V stabilized power supply. Turn on the power switch, the power signal light and instrument will light up, and the instrument will display the water temperature of the pool and the ambient air temperature respectively. Select the function switch according to the natural conditions of the local area. If it is not necessary to select, place the switch completely in the ON position and the machine will automatically enter various execution programs (Single function selection can save electricity).
The selection of microcontroller instrument setting values. The temperature value of this machine has been set at the water temperature (upper limit 19.5 ℃ - lower limit 20.5 ℃) when it leaves the factory, which can control the air environment temperature (lower limit 5 ℃ - upper limit 39 ℃). If your company wants to change other standards, please carefully read the instrument user manual and then make changes to the program settings. Otherwise, serious errors will occur, causing equipment failure
Please refer to the instrument instructions for the method of setting up the instrument:
This instrument has two temperature display windows that display water temperature and indoor air temperature respectively, and two setting windows that set the upper and lower limits of water temperature and air temperature respectively Its purpose is to automatically shut down the instrument when the air temperature inside the box is too high or too low to ensure that the instrument does not malfunction.
(Special attention: the instrument has been strictly adjusted to the standard program at the factory)
