Questions about the HD
The HD 6/11-4 M Plus is made for 110 V site supplies.
The HD 7/15 G, HD 9/23 G and HD 9/23 De can draw water from lakes or ponds. The HD 7/20 G Classic needs a mains water connection.
The HD 10/15-4 Cage Food has stainless steel covers, food-grade brass in every water-carrying part and a grease-resistant hose. A booster pump lets it take feed water up to 85 °C, and it is approved for chlorinated cleaning agents.
It is built to explosion-protection category II 2 G c T3, with a conductive frame and conductive tyres. Its components are protected so that surface temperatures stay below 200 °C.
Before each use, check the mains cable and high-pressure hose for damage and look for leaks; up to 3 drops a minute is acceptable. Each week, check the pump oil and clean the fine filter.
