2.1 Installation site conditions
Install this test chamber in a place which satisfied the following conditions
2.1.1 Ambient conditions
Ambient temperature range： 5～35℃；
Humidity range ： ≤85%RH
Atmospheric pressure： 86～106KPa；
Air quality： Haven’t high concentration dust and corrosive gas
Floor requirements： Flat, level floor with good ventilation
For the purpose of future easily ventilation, operation and maintaining, please install the test chamber according to below space requirements:
It needs space more than 800mm from 4 sides of test chamber.
It must have sufficient access space to ensure the door can be opened. Please do not put any objects on the front side of door, as the hot steam may damage the objects.
2.2 Power supply
2.2.1 Power supply
Check main power supply for the equipment (the diameters of electrical wire, power switch etc.) comply with below requirements:
Frequency and fluctuation: 50±0.5Hz；
2.2.2 Ground wire
Connect the test chamber to ground can avoid electric shock and reduce the noise caused by improper running.
