•
The air tube installation must not be omitted for the cold-water inlet, and we
recommend installing one for the hot water outlet also.
•
The air tube discharge must be slightly higher than the upper level of the cistern, by
at least 20 cm
(See Fig.3).
•
Long segments of piping should be avoided and/or accessories such as elbows,
T connections, distributing valves, etc. (The recommended distance between the
heater and the point of use should not exceed 5 m).
•
To have the correct hot water pressure, the cistern must be at least 2 m above the
shower level.
IMPORTANT
In the open system, DO NOT INSTALL the included relief valve, because it could cause a
loss of line pressure.
Closed or Pressurized System (direct from the water network system):
(regarding the
heater’s water supply, we recommend installing a relief valve (NOT INCLUDED) at the hot
water outlet, calibrated at (0,68 MPa) (7 kgf/cm
2
) (100 psi).
IMPORTANT
When there is excessive pressure, water exits through the relief valve. This is a normal
mechanism and does not mean the heater has a failure. Avoid undue water spills by
installing a drainage tube at the relief valve exit towards the drains.
Maximum operating pressure of 0,7 MPa (7,13 kgf/cm
2
)
We recommend checking the relief valve (included) at least once a year, to make sure it
is in good working condition.
