7.2 Remarks:
a. The pipe length between host unit and water tank should be a maximum of 5m, and the height
difference a maximum of 3m. If exceeded, this could lead to overloaded water pump, insufficient
circulation of water and affect high pressure protection of host unit.
b. Aluminium-plastic or PPR pipes are recommended for connection and should be wrapped with a heat
insulation layer and protection layer such as thin Al sheet and plain galvanized steel sheet in case of
exposure.
c. Connection and installation of the unit pipeline:
When connecting the inlet and outlet pipeline of the unit, use two pipeline grips to secure the two parts to be
connected, to ensure that inlet and outlet pipelines do not rotate (see diagram below).
.
d. Prevent air, dust or other impurities from entering the pipeline system when installing the connecting
pipe.
e. The water inlet and outlet pipeline must not be installed until the water heater is securely fixed in
position.
f. The water outlet pipe must be insulated with thermal insulation material.
