2. Product Introduction
Cooltec cabinet air conditioner is independently developed for the cooling of
communication cabinets. It is suitable for applications where the internal heat of the cabinet
is relatively large, the internal electronic equipment is sensitive to the ambient temperature,
and the inside and outside need to be completely isolated.
The Cooltec air conditioner is well-equipped, qualified, and easy-installed. It can work
immediately after powering on, no extra debugging is needed.
3. Transportation and Test
Please keep the air conditioner upright and put it in a horizontal place when it is unpacked.
Make sure to place it upright for at least five minutes before starting to operate.
Please get the correct power supply parameters from the nameplate, and then connect the
power cord to a well-grounded power supply. The minimum current of the supply line
should be at least 125% of the current shown in the design data section of the
corresponding air conditioner.
Please do not connect any other equipment to the circuit supplied to the cabinet air
conditioner in the case of being overloaded. The evaporator fan should run immediately
after the cabinet air conditioner is powered on. Please run it for about 5 to 1o minutes.
During this period, the evaporator fan and compressor should be running, and no abnormal
noise or vibration should be found.
It is necessary to set the temperature of the refrigeration thermostat lower than the ambient
temperature for the compressor to operate.
After a few minutes, the air temperature around the condenser should be warmer than the
normal room temperature.
