Installation
Installation is the responsibility of the buyer and the manufacturer does not bear the responsibility
for any damages caused by incorrect installation, damage due to poor quality plumbing and parts,
non-standard water or not following these instructions.
Mounting the Heater
-
Fit the brackets to the unit using the bolts and washers
-
Using the supplied screws, fix the brackets to the floor/wall (you may have to predrill holes)
It is recommended that the water heater be as close as possible to the place of use to reduce loss of
heat in piping.
Warning: The wall or floor must be strong enough to support four times the weight of the heater
filled with water (Approx. 40kg). The unit should be mounted to a load bearing fixture.
Pipe Connection
-
Screw the pressure relief safety valve onto the cold-water inlet. It is recommended that you
use a liquid thread sealer to ensure a non-leaking fitting.
-
We recommend adding a one-way valve to the cold water in to avoid water feeding back to
the main water supply pipeline.
Notices:
-
No responsibility is taken by the manufacturer for damage caused to the unit when not using
the supplied pressure relief valve.
-
If the water pressure exceeds 0.85Mpa or water flows constantly from the pressure relief
valve hose a pressure reducing valve must be used on the cold-water inlet.
-
We recommend adding a thermostatic valve or mixer valve to avoid the chance of the outlet
water temperature being too high.
Use of the Duoetto/Aqueous
-
Open the outlet and inlet pipelines until water flows out normally, demonstrating that the
inlet and outlet works normally and the heater is full of water.
-
Close the outlet valve.
-
Check all joints to see if there is any leakage.
-
When first using the water heater, ensure that the water heater is filled with water and that
water flows from the outlet and only then introduce any power to the system.
