Options 5.1.1 Connecting : This information is especially important to European customers concerning UROPEAN USTOMERS the use of NPT and metric threads. As a standard the accessory parts are supplied with stainless steel fittings and non-metric 1/8” NPT threads. If you intend to supply the cooling media through pipes or hoses, we recommend using the following additional accessories. -
Page 25: Avoidance Of Condensation
Options 5.1.2 Avoidance of Condensation If environmental condition makes water cooling necessary, it is strictly recommended to check whether condensation will be a real problem or not. Water cooling also causes a cooling of the air in the inner part of the device. Thereby the capability of the air to store water decreases. -
