STORAGE AND INSTALLATION
The Product Should Be Kept In a Dry And Grime Free Place
Storage Temperature:-10℃~+40℃
Storage Humidity:0%~90%
Vibration:20Hz: 9.8 m/s2 (1G) max;20Hz~50Hz:5.88 m/s2 (0. 6G) Max
Avoid Storing in Corrosive Gas And Liquid Environment
It is Best to Store It Properly Packaged On a Shelf Or Table
If it is used in an open package and it exceeds 3 months,The ambient temperature of the storage environment should not be higher than 30 ℃.This is because when the electrolytic capacitor is stored without electricity,its characteristics are easily deteriorated when the ambient temperature is too high.Do not leave it for more than a year without electricity
Ambient Temperature:-10~+50℃ (14~104℉)
Ambient Relative Humidity:<90%,no frost
Installation Height:<1000m
On a circle with a diameter of 105mm,drill 3 holes with an average angle of 120 degrees.The hole diameter is between 3-3.2 (as shown in the picture above). Mounted on The Surface With Accessory Screws M3X8.Choose one Pair of Pressure ports to connect to the Air Tube,Pay attention to the Difference Between High and Low Pressure Ports,And Make Sure to Seal the other pair of pressure ports with
On the plate that needs to be embedded,punch a hole, the diameter of the hole is between 114 and 3-114.8mm.Embed the product and install the accessory feet on the back.Then fix it on the plate with M3.5X50 self-tapping screws.Choose one of the pair of pressure ports to connect to the Airway Note the Difference Between High/Low Pressure Ports And Make Sure To Seal The Other
