H300P Temperature Humidity Chamber Page 4
Installation Location
The chamber uses only about 120W of power. For optimum operation, the ambient room temperature
should be between 85°F (30°C) and 60°F (16°C).
The chamber can be placed on any solid, level table top or work bench. For proper ventilation, allow a
clearance of at least 6” from the rear and 3” from the right and the left side of the chamber.
Before powering ON the chamber, make sure there is sufficient water in the water reservoir. Filling the
water reservoir is described in the Setup section below.
Moving and Shipping the Chamber
Caution must be observed when the chamber is moved while there is water in the water reservoir. The
chamber is equipped with two recesses on each side for gripping. When moving the chamber, make sure
the chamber is not tilted in such a way that water spills out. If any spillage occurs, leave the chamber
unplugged for at least 24 hours to allow all the spilled water inside the chamber to dry.
Before the chamber is shipped to a different location, all water must be emptied from the water reservoir.
The water can be emptied by tilting the chamber and emptying all the water into a bucket, through the
filling tube.
Make sure the unplug the chamber before filling or emptying water.
Setup
Before the H300P can be used, it needs to have sufficient water and desiccant for proper operation. The
chamber comes from the factory with the desiccant preloaded, but without any water.
Filling the Water Reservoir
Use only distilled water in the water reservoir.Do not use tap water or bottled water that is not
distilled (e.g. spring water). The impurities (salts) in regular water affect the vapor pressure and will limit
the maximum humidity the chamber can reach.
The H300P chamber should be filled with distilled water when no water is visible in the filling tube.
To fill the water reservoir follow the simple procedure below:
•Unplug the H300P from the power source.
•Unscrew the plug at the top of the filling tube (shown below).
