Installation diagram in the box
Bathroom and kitchen pipe routes, outlet and leakage-switch positions are printed and supplied with the unit — the installer follows a drawing instead of guessing.
The same 5.5 kW glass-front body, shipped with both a bathroom and a kitchen installation diagram. Wall-mounted over a shower or hung under a sink — the pipe kit, leakage switch and outlet positions are documented for each case, so installers do not improvise.
MOQ 100 pcs for custom panel colour, pattern and logo · 1,000 pcs for custom packaging. Samples from 1 pc — the sample price is higher than the bulk price, and we refund the difference once you place a bulk order within 30 days of receiving the sample. Prices are quoted per order, EXW Shanghai — tell us your quantity and destination port and we will reply within one working day.
