In order to provide for the correct operation of the counter-current machine its nozzle shall be
immersed, but not more than 300 mm below the pool water level (see Fig. 1). The optimum
position of the nozzle should be within the range of 170 – 290 mm below the pool water level.
As it is not necessary to let air out from the pump body, the counter-current unit can be installed
even in an empty pool, before filling the latter with water.
Counter-Current Unit Installation in a Full In-Ground Pool
The mounting plate, included in the delivery and attached to the lower cover of the countercurrent machine, should be used for installing the unit in the pool.
Installation of the unit requires a concrete foundation plate to be built at the pool (of B30 grade
concrete), whose upper surface should be 20 mm above the upper pool edge. In that
configuration, the counter-current unit will fit onto the upper edge strip of the pool.
The upper counter-current unit cover should be removed before installation.
The counter-current machine should be installed so that its cylindrical part is located as close as
possible to the pool wall or the pool edge strip.
The counter-current unit shall be attached to the pool body by means of M8-160 anchor bolts
(Fig. 2) using a “chemical anchor” (consisting in two-pot resin-based mortar intended for
attaching mechanical parts to mineral substrates). The bolts shall be run in concrete down to the
depth of 138 mm. For safe connection wide washers (ID 8.2 mm) and self-locking nuts should
be used. The abovementioned bolts, washers, nuts and other required materials are not
included in the delivery.

Putting the Unit into Operation and Its Control
CAUTION: During equipment operation the ventilation holes made in
its cover shall not be covered.
Switching the equipment ON/OFF
Water flow intensity control
Light ON/OFF and colour change
Air intake (bubble) control
After the counter-current unit has been mechanically fixed and connected to the mains and its
safety covers have been replaced, it is ready for putting into operation.
The equipment should be switched ON and OFF using the main (power) switch (see Fig. 6).
Fig. 6
After a longer operation time (several hours) at extraordinary high outdoor temperatures the
counter-current machine may spontaneously go off. It is caused by a thermal fuse protecting its
motor from overheating. After the motor has got cold, it will be possible to restart the machine
again.
In case the counter-current unit will not be operated for a longer period, it is recommended the
unit to be disconnected from mains using the motor starter.
Air Intake (Bubble Generation)
The control wheel of air intake is connected to three air intake nozzles by distribution
pipes. By turning the control wheel the intake air inlet may be closed or opened as
required.
Immersed Light Fitting
Light colour change is controlled using an air-operated switch, see Fig. 6. One can select
out of the following 7 colours of light: white, blue, green, red, yellow, violet and turquoise.
Operation
Warning: Certain parts of the machine are made of steel. In spite that stainless steel is used
predominantly, in connection with application of certain chemical agents (chlorine containing
ones, in particular) the following precautionary measures are recommended and should be
taken into consideration.
Chemical agents, if used, should be applied in correct amounts (doses). In particular, the agents
should not be added in higher amounts than recommended. In case that chlorine containing
agents are used, the levels of chlorine in pool water should be regularly measured and adjusted,
if necessary. (A chlorine drop test kit is commercially available in Mountfield stores, e.g., may be
used for the purpose.) M&C of pool water acidity (pH value) represent other important
factor for maintaining pool water quality.
8
Incorrect or negligent care of pool water and application of excessive dosage of chemicals may
1
result in the corrosion of metal parts of the counter-current machine, the stainless steel ones
inclusive. The most frequent causes of damage to machine metal parts are given herein below:
1) Metal parts of the machine are resistant to chlorine in water up to a certain Cl2
concentration. However, higher, excessive chlorine levels may attack even stainless
steel products and cause their corrosion.
2) Acidity (pH value) of pool water: (pH values within the range between 7.0 – 7.4 are
deemed correct). Any change in pH value of water, particularly toward lower values,
will result in its increased corrosiveness and possible corrosion of stainless materials.
3) Contents of dissolved salts – 0.5 % maximum.
When pool chemicals are added to and dissolved in pool water, the chemicals must not
get in the counter-current unit. It is, therefore, recommended THE UNIT IS NOT TO BE
USED for the time of such operations.
Further, before performing so-called “shock treatment” of pool water (using the agents
of Azuro Chlor Šok G or Azuro Modrý blesk1 type), it is recommended to remove the unit
from the pool and wait until the chlorine level drops down to its correct value.
Maintenance & Storage in Winter Period
The operator shall provide that all maintenance, supervision and installation are carried out by
persons, duly acquainted with this Operating Instruction.
Take due care of pool water purity to prevent the pump inlet strainer or even the pump body
from fouling.
Check regularly the ventilation holes made in the counter-current cover for possible obstruction
and remove any possible items or dirt that could restrict the free passage of air.
In case the equipment is not used or is left dry (e.g., in winter season), the motor starter has to
be disconnected from its supply circuit, to prevent the motor from being accidentally switched
on.
Check the equipment regularly for completeness and integrity of all covers and other
components of the counter-current unit.
For winter season it is recommended the unit to be uninstalled, removed and stored in a dry
area. However, it is also possible to let the unit installed outdoors, provided that no of its parts
remains immersed in water.
When the swimming pool is filled with water again, or the unit is installed back to its place, the
water inlet holes in the unit body shall be checked for free cross section.
The counter-current machine shall not be started without being immersed in water!
Liability for Defects
Provided that all the conditions of use have been met, as stipulated by the manufacturer in this
document, the manufacturer shall provide the user with the extended period of liability for
defects lasting 7 (seven) years. Other terms and conditions of manufacturer’s liability for defects
are set out in seller’s warranty.
The service and replacement parts for the product shall be provided by Mountfield, a.s., through
the network of their stores.
