INSTALLATION NOTES • Big cabinets need more heating power and require multiple heaters ( parallel connection ). Ask us about specific power and length; • To maximize convection effect prefer a vertical installation and ensure a minimum clearance of 50 mm around heaters; • PTC based heaters are self- power and temperature limiting appliances. No additional safety devices are normally needed; ■M heating at a preset level of relative ON heating circuit even when cabinet is POWER CALCULATION • Use the following formula to calculate the required electrical heating power: P-> required heating power in Watt; Depending on cabinet material: K = 3J W/m2°C stainless steel cabinet K = 5,5 W/m2°C painted sheet cabinet; S-> equivalent cabinet surface in ml; At-> required temperature difference between internal (target) and external cabinet MOUNTING OPTIONS • Screw mounted (four mounting holes); Please ask us for special fastening options.
