Grunbeck HEH 9 Operation Manual

Leakage test
The HEH 9 water softener needs to be
checked for tightness after installation and
after each maintenance. In order to do so,
apply the highest operating pressure that
might occur and check the HEH 9 water
softener visually for tightness.
Documentation water meter
Prior to each filling resp. refilling of the
heating system, the water meter reading
and consequently the soft water capacity
needs to be checked and the exchanger
resin must be replaced, if necessary.
The water volume that has passed through
and the raw water hardness must be doc-
umented in table 1.
The max. soft water volume that can be
achieved subject to the raw water hardness
is indicated in fig. 6.
In case the soft water is blended to a de-
sired residual hardness, the soft water
volume achieved (blending water) will
increase accordingly.
Examples
Raw water hardness 20 °dH (35.6 °f)
 900 litres with 0 °dH (0 °f).
Raw water hardness 20 °dH (35.6 °f) and soft
water hardness of 10 °dH (17.8 °f)
 1800 litres with 10 °dH (17.8 °f).

If several filling procedures are done with
one HEH 9 water softener, the soft water
needs to be checked (water test kit) subject
to the raw water hardness during the filling
process and the results must be document-
ed (refer to table 1).

If the exchanger resin of the HEH 9 water
softener is exhausted, it must be replaced.
Depressurise the HEH 9 water softener
(close inlet and outlet - open sampling
valve). Unscrew the union nuts at the
distributor valve and dismount the entire
distributor valve from the exchanger tank.
Remove the riser pipe from the exchanger
tank and completely drain the exchanger
tank. Wash out any residues with water.

Note: The exchanger resin may be dis-
charged together with the domestic waste
(waste code number 57125).
Insert the riser pipe into the exchanger tank
again. Close the riser pipe (by means of a
plug or adhesive tape). Fill in the new
exchanger resin into the exchanger tank.
Centre the riser pipe - remove resin sticking
to the thread and riser pipe - and remove
the plug from the riser pipe. Remount the
distributor valve. Remount the connection
hoses. Deaerate the HEH 9 water softener.
Document the water meter reading and the
raw water hardness.
The inspection only comprises a functional
check (check of soft water hardness at
sampling valve) and its documentation.
Consumables and spare parts can be pur-
chased from the sanitary trade or from your
local Grünbeck technical service.
