INSTALLATION

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 200 – 300 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 for above ground pools

The mounting plate, included in the delivery and attached to the lower cover of the counter-current 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. 3 ) 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 beused. The abovementioned bolts, washers, nuts and other required materials are not included in the delivery.

Counter-Current Unit Installation in a Full In-Ground Pool

The telescopic adjustable leg shall be used for installation. That telescopic leg is not included in the delivery. The counter-flow unit should be installed on a foundation plate made of concrete (B30) whose surface should be found from 767cm to 1390cm below the level of the swimming pool upper edge. The telescopic leg should be then adjusted in length to lay the counter-flow unit on the pool upper edge. The upper cover of the counter-flow unit should be removed before commencing the installation. Next it is necessary to remove the mounting plate from the lower cover of the countercurrent. The stand is then mounted with the same screws.
The unit should be installed so that its cylinder tube is placed as close to the pool wall or edge rim as possible. The unit should be anchored to the foundation plate by means of M8-160 (Fig. 3) bolts using a chemical anchor system. The bolts should be set in the concrete foundation plate to the depth of 138mm.The counter-flow unit should be fixed to the plate using ø8.2mm washers (wide type) and M8 locknuts. Neither the bolts, nor other anchoring material comprise a part of the delivery.

Counter-Current Unit Wiring

The counter-current unit may be connected to the mains only after its body has been properly (mechanically) anchored to the pool. Connection to (or disconnection from) the power supply network may be carried out only by a duly qualified electrician (to Decree 50/1978 Coll., Art. 6) in compliance with applicable electrical regulations and standards, ČSN 33-2000-7-702 in particular.

The counter-current unit shall be connected to the distribution network by means of the motor starter, fuse and residual current circuit breaker (as indicated in the wiring diagram in Fig. 4). Failure to instal any of those safety devices may result in (even fatal) electrical accident and represents a cause of general hazard. The concerned equipment shall be located outside of the pool protective zone (i.e. zones 0, 1 and 2 to ČSN 33 2000-7-702), including the areas found within the distance of 3.5 m from the pool wall, see Fig. 5.

The motor starter, fuse and residual current circuit breaker shall be placed in a lockable distribution box, well secured against any intervention of unauthorised persons.

The supply cable of the minimum wire cross section of 1.5 mm2 shall be pulled through the grommet in the lower cover of the unit (see Fig. 3) In the box it shall be secured against pulling it out by routing it over the distribution box cable grommet. The supply cable shall be routed to the counter-current unit in a buried cable protecting tube, see Fig. 6.

The counter-current unit shall be earthed using a separate earth wire of the minimum cross-section of 2.5 mm2. Its lug should be connected to the earth terminal found in the lower part of the unit cover, as shown in Fig. 3. The earth wire shall be routed to the unit in the buried cable protector, together with the supply cable. On its other end the earth wire should be connected to the earth terminal in the distribution box.

Before connecting the unit to the supply network all protective covers and guards of the unit shall be put back to their positions and secured.

PUTTING THE UNIT INTO OPERATION AND ITS 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. 7 ).

After a longer operation time (several hours) at extraordinary high outdoor temperatures the counter-current machine may sponta- neously 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.

CAUTION: During equipment operation the ventilation holes made in its cover shall not be covered.

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. M&C of pool water acidity (pH value) represent other important factor for maintaining pool water quality. Incorrect or negligent care of pool water and application of excessive dosage of chemicals may 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, 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!
