5.1 Faults and fixes
If problems arise when the product is in use,
check for these possible faults:
1. Water leaking from pipe connection. Pos-
sible cause: Pipe connection is loose or
sealant is insufficient. Possible solution:
Tighten pipe connection, replace sealant
if necessary.
2. Water leaking from the tank, not the pipe
connection. Possible cause: Leakage from
the steel tank. Possible solution: Check if
it is possible to see the leak point. Con-
tact installer.
If you are unsure what is wrong, contact the
installer (see product type plate) or OSO Hot-
water AS - see section 6.1.

First check that all pipes are connected correctly.
Then proceed as follows:
A) Open for venting at a point in the system
higher than the top of the tank; use e.g. the 3/4”

B) Open the water supply to the product. When
water flows out of the venting point, the tank is
full and the vent can be sealed.
