Page 7: On-Site Requirements
2 Installation requirements The steam sterilizer works with a cooler on the rear of the device. The function and life-span of the steam sterilizer can be compromised if heat dissipation via the cooler is restricted in any way. The steam sterilizer may only be installed if sufficient air circulation can be guaranteed. - Page 8 Water stop For insurance reasons, MELAG recommends the installation of a water stop with a cut-off valve (e.g. from MELAG), as the MELAdem 40/MELAdem 47 are under constant hydraulic pressure from the domestic water supply. PLEASE NOTE Fit the outlet hose at a constant decline without kinks or sagging. In case of deviations to the installation arrangements, consult with MELAG.
