Installation Notes for UV Testing Chambers

The UV weathering test chamber simulates the damage caused by the sun’s ultraviolet light, and the weather resistance test is carried out on the material by exposing the tested material to light under controlled high temperature. The weathering chamber uses ultraviolet lamps to simulate the radiation of sunlight, and simulates dew and rain through condensation and water spraying.

In just a few days or weeks, the ultraviolet irradiation equipment can reproduce the effects of outdoors that take months or even years. Damage that occurs over time, including fading, color change, tarnish, chalking, cracking, cracking, wrinkling, blistering, embrittlement, loss of strength, oxidation, etc. Its test results can be used to select new materials, improve existing materials, or evaluate changes in material formulations|Mechanical Structure of UV Testing Chamber

UV testing chamber
The uv test chamber is for indoor use only. Locations where this equipment is located without ventilation can negatively impact temperature uniformity. Room Temperature Installation Location
Placing the uv aging test chamber in an air-conditioned room is very helpful for temperature stability (this is very important).
The operating temperature of this equipment is preferably in the range of 70°F (21°C) to 80°F (27°C). When the indoor temperature exceeds this range, the test temperature will be difficult to control.
High temperature environments can affect sample cooling resulting in improper condensation.
The ideal location for this device is an air-conditioned laboratory or office.
This device will not be tired in the air conditioner, Because the heat generated by it is the same as the heat emitted by two ordinary people.
If the uv testing chamber is placed in a location without ventilation, it will cause one end of the machine to be colder than the other.
Do not place the device in a place with strong air flow, Otherwise it will greatly affect the temperature difference between the two ends of the device. Ventilation:
-40°C to 80°C (Transport and Storage Temperature:) Temperature:
Pollution level is II. Pollution Control:
When you place several UV test chambers in the same space, It is necessary to keep the distance between each other, Take care the distance from the testing machine and the wall. Floor Space
If the distance between these weathering chambers are too small, They will interfere with each other, Then it will be difficult to open the door, Meanwhile, It will be difficult to remove samples and maintain the machine as well.
No more than 74dBA Noise Level:

UV testing chambers play a crucial role in assessing the reliability and performance of materials, surfaces, and products exposed to ultraviolet (UV) radiation. Designed specifically to recreate accelerated outdoor weathering conditions, these chambers offer accurate and controlled UV exposure, enabling manufacturers to evaluate the performance of their materials and products under a range of extreme conditions. This installation guide aims to provide essential information and guidelines for the proper installation and setup of UV testing chambers, ensuring they operate efficiently and deliver accurate results. Please send us an email if you still has any unclear on this installation steps.
220V ±10% Power Voltage: Power Requirements
4.5 KW→ Power Max Consumption:
The circuit breaker is part of the main power switch, so if you connect several devices on a high load capacity circuit, each UV test chamber still has proper current protection. Power Switch:
If your circuit is 25A, then each device should have its own circuit. Each 220V UV accelerated weathering tester has a built-in 25A circuit breaker.
50Hz or 60Hz Frequency:
The power socket should be as close as possible to the equipment, and it is best not to use an extension cord. Power Socket:
220V component users must attach a single-phase grounding plug according to the local electricity, power cord code: Power Plug:

Troubleshooting Guidance for UV Aging Test Chamber

UV aging test chambers, also known as UV weather resistance test chambers, are vital equipment for evaluating the durability and performance of materials when exposed to UV radiation.

Installing a UV testing chamber is a crucial step in ensuring accurate and reliable UV weather resistance testing. By carefully considering the location, following technical requirements, implementing safety precautions, and performing regular maintenance, users can maximize the performance and longevity of their UV testing chambers. Proper installation will result in precise test results, enabling manufacturers to develop UV-resistant materials and products that meet the stringent demands of various industries.
The UV weathering test chamber has condensation and therefore all have water requirements. Water spray is also required in the spray mode. The water quality requirements are as follows. Water Requirements
NOTE: Clean water is not required if running only for radiation testing.
Water is needed for condensation, and the automatic water inlet connected to the machine is a PVC4-point (20mm) male threaded joint. Condensing Test
Ordinary water pipes can be used, and distilled water is not necessary. The water vapor passing through the test sample is distilled from the water in the water pan.  Water Purity:
However, distilled or deionized water will reduce solids in the bottom of the pan.
Do not use a water softener to pretreat the water, as this only displaces the sodium ions. Softening water increases the corrosivity of the water.
About 8 liters of water per day. Water Volume: 
It is only necessary to connect the external water source and the water inlet and outlet of the equipment with the external threaded pipe (20mm). Water Pipe Connection: 
The water level has been adjusted before the equipment leaves the factory, and it is about 20mm to 25mm away from the bottom of the water pan. Water Level Adjustment: 
In addition to the tap connected to the water inlet, the equipment requires pure water for the spray test. Water Purity Statement: Water Spray Test
The pH of the water should be between 6.0 and 8.0.
The resistivity of spray water should be greater than 200kohms-cm.
Actions such as deionization, distillation or filtration are required,
Low purity water can cause sample spotting or orifice clogging.
In order to avoid pollution, all pipes, valves and devices of purification devices and equipment are required to be stainless steel or plastic products. Please do not use iron, steel, copper, or brass materials
The uv testing chamber is pressurized by a high-power stainless steel pump to ensure the flow rate and uniformity of the spray. Water Pressure: 
It requires 7 liters of water per minute (LPM). For most tests, just spraying water is rarely the time per day. Water Volume:
The drain pipe has been installed in the lower part of the machine. This water pipe must be closed when the machine is running. The water in the water tray needs to be drained during cleaning and maintenance. At this point the hose should be open. Drain Cleaning: Water Discharge
When the unit runs the spray test, water is stored in the water pan, and when the water exceeds the overflow in the water pan, the water will flow from the overflow back to the tank. Water in the Water Tray Overflows:
During the cleaning process of the water tank, the equipment must be stopped, and the power supply must be disconnected. Open the drain valve, and the water in the water tank will be discharged directly from the drain port (20mm external threaded pipe). Water Tank Cleaning:
