KRIBA Z Series Pool Filter
SAFETY NOTICE, PLEASE READ THEM CAREFULLY
- All electrical connections should follow the European Standard regulation
NF C15-100
NF EN 60-335-2-41
- Which refers to the «construction of electrical installations«, both in outdoor as in indoor pools, or similar regulations specific of each area or country.
- Electric installation should be performed by a professional qualified for electric installations.
- When filling the tank with sand, sand should not exceed 2/3 of the tank height.
- Do not start the device before it has been previously primed.
- When handling the filter or valve, always disconnect it from the electricity supply.
- Do not allow children or unauthorized adults to manipulate the filter.
PACKAGING COMPONENTS
The filter you just purchased has been specially designed for pools. Thanks to
its design and functionality you have all necessary elements to clean and
filtrate the water of your pool. This packaging contains the filter body and
the valve. Main components of this filter are the following:
BEFORE CONNECTING
THE FILTER
Location
The filter must be installed as close to the pool as possible, preferably
within 50 meters of the surface of the pool. Be sure there is a drainpipe in
the spot where the filter will be located. This drainpipe must be adequately
sized to the installation flow.
Be sure the surface area where the filter is installed is horizontal, stable,
resistant to the weight of the filter, and is completely clean.
There must be enough space in the area around the filter so that the required
inspections and maintenance throughout the life of the pool can be carried
out.
Installation
Once the filter has been placed in the right location proceed as follows:
FIG. POS. DENOMINATION
- 1 1 Cover
- 1 2 Filter body
- 1 3 Out filter
- 1 4 Filter base
- 2 1 Manometer
- 2 2 Air relief valve
Make the three connections needed for the selector valve:
- pump tubing to the valve,
- valve to the waste drain
- and from the valve to pool return
Each of the three outputs is identified on the valve. See Figure No. 3.
-
Install the selector valve in the filter, ensuring that the gaskets between the valve and the filter are correctly positioned and none of the gasket has dropped inside the filter tank. Place the bag to avoid sand getting into the pipe.
-
Fill the filter with water up to the half way point. Pour the necessary quantity of sand into the filter. It must be filled with silica sand with a particle size from 0.4 to 0.8
mm. with the quantity indicated in the table of characteristics. Silica sand should be only replaced in case of sand loses. See figure no. 4 -
Clean the area around the cover seal and remove the bag..
-
The nuts of the cover must be strongly tightened.
-
Once the filter is filled with sand it is necessary to carry out a wash cycle. Proceed as described in the paragraph 4.2.
SELECTOR VALVE
The selector valve has a handle of 6 positions that selects any of the necessary operations to obtain the maximum efficiency from the filter: filter, backwash, recirculation, waste, rinse and closed. These 6 positions are identified on the label on the top of the valve.
Manometer assembly
For the assembly of the manometer is not necessary the use of tools or Teflon
tape; use the o-rings and fix it by tightening it with your hands (see figure
no. 2).
Change of valve handle function (see figure no. 5)
IMPORTANT: The pump should be switched off when the position of the selector valve handle is being changed
- Press softly the valve handle until freeing the rib from its housing (1º)
- Proceed to turn the handle to its desired position until the rib fits in the housing in front of the function (2º)
- Release the handle softly, checking that the rib is perfectly coupled in the housing
FILTRATION
This filter is based on the silica sand inside the tank, capable of retaining
any dirt coming from the pool. The water is drawn in from the bottom of the
pool and is carried through the pump to the filter. The silica sand load
through which the water circulates in a descending motion, retains the debris
suspended in the pool and send clear water back to the pool.
Trees, insect, bath frequency, weather conditions determine the dirt degree of
the water, as well as the frequency of cleaning the sand filter (see paragraph
4.2.). Filtration is only one part of maintaining clean swimming pool water,
and it is inseparable from the chemical treatment; one without the other will
not achieve the desired result.
NEVER PLACE THE CHEMICAL
PRODUCT IN THE BASKET OR THROUGH THE FILTER. IT COULD DAMAGE THE COMPONENTS OF
THIS DEVICE AND REDUCE ITS EFFICIENCY.
Priming of the filter
The filter should be at all times correctly primed. Not being properly primed
means that an air chamber has appeared inside the filter tank, thus preventing
the proper circulation of the water, and, consequently, the proper functioning
if the filter.
How to prime the filter?
- Place the valve handle in the Filter position. Slightly loosen the drain screw placed by the manometer. This will allow the air kept inside the filter body to escape the tank.
- Once ONLY water is coming out the drain (between 10 and 20 seconds), tighten again the drain screw.
NEVER MANIPULATE THE VALVE WITHOUT SWITCHING OFF THE PUMP
Filtration
- Filtration is only one part of maintaining a clean swimming pool, and it is inseparable from the chemical treatment; through the filter the water is physically cleaned, retaining the debris particles in the water. In fact the purification process consists of a perfect combination of the two treatments; chemical and physical.
- With the pump switched off, move the selector valve handle to “FILTRATION”.
- Turn on the pump.
- While it is operating, it is best to periodically observe the pressure gauge, where the filter saturation degree is indicated.
Before using the filter for the first time, the sand should be backwashed (see paragraph 4.2.)
When it is necessary to wash the filter sand?
Each load of sand forms thousands of channels which pick up all the material
contained and caught up in the filtering process, the number of free channels
allowing the water to pass is continually decreasing.
This is why the pressure rises progressively until it reaches the saturation
level At
this pressure, yellow or red area of the manometer, the filtering sand is
unable to collect any more impurities and must be cleaned.
If you observe a decrease of the return water flow, check also the filter
pressure.
Wash
Con el proceso de autoclaved proceeds a With the valve in the Backwash
position, the sand inside the filter will be cleaned by reversing the water
flow direction.
Proceed as follows:
- Switch off the pump. Never manipulate the valve handle before switching off the pump.
- Press the valve handle until freeing the rib form its housing, figure 5.
- Turn on the handle until the BACKWASH position, figure 5.
- Switch on the pump and let it run for 2 minutes. Carry out this process until you can see transparent water running past the valve viewfinder.
- Switch off the pump
- Turn on the valve handle to the RINSE position. Switch on the pump again and let it run for 1 minute.
- Switch off the pump and turn the handle to the FILTER position
- Switch on the pump and proceed with the filtration process.
Rinse
After the carrying out the “BACKWASH” operation on the filter and placing the
installation in the “FILTER” position, the water flowing into the swimming
pool will be cloudy for a few seconds, so to prevent it from reaching the
swimming pool there is a “RINSE” position for the selector valve which is
operated as follows:
- immediately after the “BACKWASH” switched off the pump
- Turn the valve handle to the “RINSE” position, figure 5.
- Switch on the pump and let it run for 1 minute.This position ensures that the filtered water goes directly to the drain.
- Switch off the pump and turn the handle to the FILTER position
- Switch on the pump and proceed with the filtration process
Closed
As its name indicates, this position is for closing off the water from the
filter to the pump and it is used for opening the collector prefiltre of the
pump.
Recirculation
In this position, the selector valve allows the water coming from the pump to
go directly to the swimming pool without passing through the inside of the
filter.
Waste
If the swimming pool needs to be completely drained, this can be done using
the filter pump. In order to do this, the selector valve should be placed in
the “WASTE” position. The motor should run with the main drain valve fully
open, for the pump to have sufficient suction. For the pump to suction, keep
the main drain pipes full of water. Before drainage, make sure that the
skimmer valves and the bottom cleaner valves are closed.
Keep in mind that the pool water will not be 100% removed, some centimeters
will always be left. Once the pump does not suction any more water, switch it
off.
