Frequently Asked Questions - CristalProfi e401 JBL

How to prime the JBL CristalProfi e401 filter?

Check that the levers are set to OPEN. Place the outlet pipe above the water level. Press the START button several times until water enters the suction hose. Wait until the filter is filled, then plug it in. Shake the filter gently to remove residual air.

When and how to clean the filter media?

Clean the pre-filter foam F1 regularly (every 2 months). The other media (F2 to F5) should be cleaned every 6 to 12 months with warm water (25 °C). Never clean all media at once to preserve bacteria. Replace the foams after 3-4 washes.

What to do if the filter does not pump water?

Check the power supply. Ensure the filter is primed (no air). Check the rotor and ceramic shaft: they must be correctly installed and not blocked. Clean the rotor if necessary. Verify that the levers are set to OPEN and the hoses are not pinched.

How to install the filter under the aquarium?

Place the filter in the cabinet, respecting a maximum height difference of 180 cm between the water surface and the bottom of the filter (120 cm for e401). Use the suction cups and hooks to attach the pipes. Connect the hoses to the IN (black) and OUT (gray) markings. Tighten the nuts counterclockwise.

Why has the filter flow rate significantly decreased?

Possible causes: levers not set to OPEN; hoses pinched or clogged; intake strainer blocked; dirty filter media (especially F1); dirty rotor. Clean the media, hoses with a brush (JBL Cleany) and the rotor. If the problem persists, check for air in the filter.

The filter is noisy, what to do?

Abnormal noise may come from a poorly mounted rotor or a broken ceramic shaft. Disassemble the housing, clean the rotor and shaft, check the rubber supports. Ensure the housing is properly closed (position CLOSE). If the noise persists, replace the rotor/shaft/supports assembly.

How to change the filter without disturbing the aquarium?

Run the old and new filters in parallel for two weeks. You can also reuse 1/3 of the filter material from the old filter in the new one to preserve beneficial bacteria. Avoid any general cleaning of the aquarium during the change.

What are the important safety instructions?

Always unplug the device before any maintenance. Form a drip loop on the cable. Never immerse the pump head in water. Use the filter only in an upright position and indoors. Children under 8 years old should not clean the device.

How to maintain the rotor and pump housing?

Unscrew the housing cover (turn to OPEN). Carefully remove the rotor (attention to magnets). Clean the housing, rotor and cover with a brush and rinse with clean water. For limescale, use JBL Clean A. Reassemble by correctly positioning the rubber shaft supports.

What is the lifespan of the filter media and when should they be replaced?

The pre-filter foam F1 should be replaced every 2 months. The MicroMec balls (F2) last up to one year; replace them when they crumble. The foams F3/F4/F5 should be replaced after 3-4 washes (approximately every 6-12 months). Clean the hoses and intake strainer regularly.

Description of functions

The JBL CristalProfi greenline Filter cleans the tank water in a closed circuit.

A maintenance-free pump built into the filter head ensures permanent water circulation. The water is fed from the aquarium into the filter media basket, where it flows through the filter media from the bottom to the top and is cleaned appropriately, before being pumped back into the aquarium. The filter is NOT self priming. The air initially contained in the system must be removed before starting the appliance. This can be done by selecting the built-in quick-start option by pushing the priming button.

Special features

• Energy efficient

The filters of the JBL CristalProfi greenline range consume up to 43 % (depending on model) less power than previous comparable models.

• High capacity, quiet

New motor technology delivers the same effective water circulation in your aquarium as previous models. Optimised pump impeller with ceramic bearings ensures very quiet running and long service life.

• Seldom needs cleaning

Immediately below the pump head, there is an innovative, patented [EP 1832164] combi filter basket containing pre-filter media on the right and left, which are very easily accessible. The remaining pre-filter media seldom need cleaning, providing the pre-filter media are replaced regularly.

• Complete with JBL MicroMec high-capacity biological filter balls

The round shape and varying diameter of the balls produces a self-cleaning effect. As a result, these filter media only need cleaning at very long intervals.

- The main filter media can be used for up to a year when used in conjunction with the easily cleaned pre-filter.

• Fully fitted and ready to install

A wide range of accessories guarantee easy connection to almost any freshwater or marine aquarium.

• Simple to start, safe to use

The built-in quick-start priming button makes starting the filter child's play, without the annoyance of manual priming.

All the parts of the filter are easy to fit and designed in such a way that incorrect assembly is impossible.

An innovative patented [EP 1869973] hose connection block prevents water leakage when the block is disconnected from the filter.

Tested to TÜV/GS

• Complete and ready to plug in

The filter is fully ready to plug in and equipped with filter media. The filter media have been selected to ensure efficient manual and biological water purification that leaves your aquarium water clear and healthy.

A wide range of accessories guarantee easy connection to almost any freshwater or marine aquarium.

Installation

1 Unpacking and preparation

Carefully remove the filter and the separate accessories from the packaging and check that nothing is missing. In the event that anything is missing or damaged, please contact your specialist retailer.

Open all 4 locking clips on the filter container and remove the pump head. Serial Numbers 12-27-0001 and up of the CristalProfi greenline external filter range have a new water distribution plate (4) which seals against the upper combi filter basket with a U-profile. Take out all the filter baskets one at a time and thoroughly rinse all the filter media under lukewarm mains water. Place the filter baskets back in the filter canister in the original order.

Before you fit the pump head, biologically activate the filter media with JBL FilterStart cleansing bacteria (available at your specialist retailer) as follows:

Empty the complete contents of the required number of bottles of JBL FilterStart over both of the pre-filter media in the combi filter basket.

Number of bottles of JBL FilterStart:

CristalProfi e401: 1 bottle

CristalProfi e701: 1 bottle

CristalProfi e901: 2 bottles

CristalProfi e1501: 3 bottles

CristalProfi e1901: 4 bottles

Put the pump head back on the filter canister and close the locking clips.

Please note: The empty filter baskets are interchangeable (excepting e401). However, the combi filter basket is the only one that can be inserted last on top. The pump head can be turned 180^ in any direction.

Tip: Always open and close clips positioned opposite each other. This prevents unnecessary wear on the pump head seal and ensures an accurate fit when the filter canister is closed.

2 Attaching the hose connection block and hoses

Turn the two small stopcock levers on the pump head to the (●) position opposite the "OPEN" mark, so that the groove in the base of the levers points vertically upwards.

Place the hose connection block with the middle lever pointing upwards into the pump head and press it down firmly.

To fasten, press the middle lever down to secure and turn the two small stopcock levers to the "OPEN" position. Now the ball valves integrated in the hose connection block are open and the hose connection block cannot be removed, even if the middle lever is raised (safety lock). Push each hose onto a hose connection and turn the nut anti-clockwise until the hose fits firmly.

3 Positioning the filter

The filter can now be positioned in the intended place for use in the aquarium cabinet or similar. attention must be paid to the following: If the filter is to be housed in the cabinet, the distance in height between the surface of the water and the bottom of the filter may not exceed 180 cm max. (max. 120 cm for the e401 ). If the filter is located next to the aquarium, the distance between the surface of the water and the top of the filter must be at least 20 cm.

CAUTION: the filter should always be operated in an upright position!

4 Attaching pipes and hoses

Place the intake strainer on the end of the suction pipe and attach it to the inside of the aquarium using the suction cups and pipe clips. Use long or short clips depending on the design of the aquarium edge. Pull out the telescopic pipe so that the intake strainer is about 5 cm above the base of the aquarium. The two parts of the telescopic pipe are sealed against one another by an O-ring so that no air is drawn into the telescopic pipe, even if the

water level is low (e.g. in a turtle tank).

Connect the water outlet pipe, angle piece and spray bar (if required) and secure them in the aquarium with suction cups. First, remove the end cap of the spray bar and only replace it when the filter is operating.

Tip: We advise against using the spray bar in aquariums containing plants, as too much of the vital plant nutrient, CO2, is expelled from the water. The best results are achieved by using the water outlet pipe with an angle piece or a wide jet pipe with the outlet just below the surface of the water to produce moderate surface agitation. The distance between the outlet and the surface of the water can be individually set by using the two extension pieces.

Connect the hose with the suction pipe from the "IN" position on the hose connection block (black elbow connection) and the hose with the water outlet pipe from the "OUT" position (grey elbow connection). Firmly attach the hoses by turning the nuts anticlockwise until they are tight.

Cut the hoses as short as possible to avoid kinking. This also makes priming easier.

Starting up

Make sure that the two small stopcock levers on the pump head are in the "OPEN" position. During the following start up procedure, the water outlet pipe with the spray bar, etc. must be positioned ABOVE the surface of the water for optimum ventilation of the appliance.

Press the "START" button on the pump head repeatedly with the palm of your hand until water begins to flow into the suction hose (hose on "IN"). Wait until the filter has completely filled with water and the water in the hose leading to the water outlet pipe (hose on "OUT") is at the same level as the surface of the water in the aquarium.

Connect the filter to the mains power supply. The water will now flow out of the water outlet pipe into the aquarium. At first, it may be mixed with air that is still trapped between the layers of the filter media. Gently shake the filter to dislodge the air which will escape with the stream of water.

Please note: If you replace an existing aquarium filter with a JBL CristalProfi external filter, we recommend running both the new filter and the old filter parallel in the same aquarium for the first 2 weeks, before dismantling the “old” filter. This ensures that the new filter has a sufficiently large colony of cleansing bacteria and avoids harmful nitrites occurring in the transitional phase.

Check that all parts are watertight.

Regulating water flow

The water flow can be regulated by the stopcock labelled OUT if required (grey elbow connection). The further the lever is turned away from the "OPEN" mark, the less water is pumped by the filter. Never use the lever opposite to regulate flow!

Important: Reducing capacity by more than half should be avoided for the following reasons: running noise may increase, the service life of the rotor may be shortened and the cooling required when the pump head is in operation is no longer reliably guaranteed.

Note on the pumping capacity

For optimum reliable performance, we strongly recommend the use of JBL original filter media only.

As usual technically, the data given on the type plates and the packaging refer to maximum IDLE RUNNING DATA of the pump, without hoses and filter media:

CP e401: 450 l/h

CP e701: 700 l/h

CP e901: 900 l/h

CP e1501: 1400 l/h

CP e1901: 1900 l/h

When operated in an aquarium, this data is reduced by varying degrees, depending on the length of hose and the filter media used. An accumulation of dirt in the hoses and filter media will further reduce performance.

The following approximate capacities refer to a hose length of 1.5 m and operation with the supplied filter media in a clean or new condition:

CP e401: 200 - 250 l/h

CP e701: 350 - 400 l/h

CP e901: 380 - 450 l/h

The filter media and hoses should be cleaned when these levels are reduced by about 50%.

Maintenance and care

All JBL CristalProfi greenline external filters are supplied with a standard filling of filter media to provide clean and healthy aquarium water for “normal” operation. The filters provide extremely good conditions for the development of colonies of cleansing bacteria which play an essential role in the breakdown of pollutants. Mechanical pre-filtering ensures that these bacteria can efficiently carry out their task undisturbed for as long as possible.

You can of course adapt to your special needs by selecting from the wide range of available JBL filter media. Depending on your choice of filter media, this may influence the pumping capacity of your filter and the length of time the filter media can be used.

Note: Regular maintenance and cleaning of the filter is vital to prevent a reduction in the pumping capacity.

7 Cleaning or replacing filter media

Make sure to always disconnect the mains plug before carrying out any work on the filter!

Turn the two small stopcock levers on the pump head to the stop position (●) opposite the "OPEN" mark. Lift the middle lever on the hose connection block as far up as possible and push to the stop position. This slightly lifts the hose connection block out of its seat. Pull upwards to lift the hose connection block out. The ball valves in the hose connection block are now closed and retain the water in the hoses. This prevents accidental opening e.g. by children and any associated unwanted leakage of water.

Open the 4 locking clips on the filter canister and remove the pump head.

Remove the filter baskets with the filter media and rinse the filter media in lukewarm water (25°C). Never wash ALL the filter media at the same time, as too many beneficial cleansing bacteria would be washed away. The JBL CristalProfi filters of the e range are designed so that, as a rule, only the pre-filter material (F1) has to be cleaned whilst the remaining filter material must be cleaned at longer intervals.

Tip: Do not forget to clean all the hoses and pipes regularly with an appropriate brush (e.g. JBL Cleany), as bacterial deposits on the inside of the pump drastically reduce the pumping capacity of the filter.

8 Function and replacement intervals of the individual filter media

(F1) JBL Pre-filter media

Mechanical pre-filter media made of coarse foam cut into a T-profile to absorb as much coarse dirt as possible. These media should be changed every 2 months. They can be rinsed once or twice.

(F2) High capacity biological filter balls (JBL MicroMec):

JBL MicroMec is a highly porous biological filter medium made from sintered glass and with a special surface and pore structure, which provides excellent conditions for colonisation by beneficial cleansing bacteria. This allows an effective biological breakdown of pollutants. It

is therefore particularly well suited for intensive long-term filtration in freshwater and marine aquariums. The round shape and varying diameter of the balls produce a self-cleaning effect. As a result, this filter material only needs rinsing briefly every 6 – 12 months, depending on the amount of dirt. Change when the balls begin to disintegrate.

Filter media to solve particular problems can be found in Chapters 12 and 13.

(F3) Filter foam pad

Medium-pored foam pads for effective biological filtering with ideal conditions for colonisation by cleansing bacteria. The pads have a section which can be removed and replaced with filter material to treat specific problems. (section D). Careful cleaning is required approximately every 6 months. Replace after cleaning 2 to 3 times. Only one of the two pads should be cleaned or replaced at a time.

(F4+F5) Filter foam pad

Set of one coarse foam pad and one fine foam pad for the middle section of the combi filter basket. The coarse pad provides biological filtration through the colonisation of cleansing bacteria. The fine pad traps particles of dirt which could damage the pump, as well as providing biological filtration. The grooves on the top side of the fine pads are intended to hold special JBL Stixx for long-term fertilisation of aquatic plants. The coarse pad should be cleaned approximately every 6 months. The fine pad should be cleaned about every 4 months or as required (if pumping capacity deteriorates). Replace after cleaning three to four times.

$$ (F 1 + F 4 + F 5 = J B L \text { Combi Bloc }) $$

9 Cleaning the hoses

Bacteria settle in the hoses producing slime, which can significantly obstruct the flow of water. Algae growth only occurs in strong light. The hoses should therefore be cleaned regularly with a cleaning brush (e.g. JBL Cleany). Simply rinsing with tap water is not enough!

10 Cleaning the impeller and casing

Turn the cover of the impeller casing anti-clockwise towards "Open" and remove the cover by pulling gently.

Pull the impeller out of the casing. CAUTION: the impeller is held in the casing by magnetic force. Take appropriate care when removing the impeller, making sure to avoid injuring your fingers.

The ceramic shaft is held by two rubber bearings, which remain either on the shaft or on the bottom of the impeller casing, or in the middle of the casing cover, when the impeller is removed.

Clean the impeller casing, impeller and shaft with a suitable cleaning brush, then rinse in clean water. Limescale can be easily removed by soaking in JBL Clean A (available at your specialist retailer). Never dip the pump head in water or other liquid to clean it. Use a damp cloth (e.g. JBL WishWash) to clean the surface of the casing.

Place the ceramic shaft and impeller back in the casing. Check that both rubber bearings are present and correctly positioned for the ceramic shaft. Put the impeller cover back in and, pressing gently, turn the cover towards "CLOSE" until the stop point.

Please note: If the impeller has to be replaced due to wear and tear, the complete set comprising the impeller with the shaft and 2 rubber bearings must be replaced. Only this way can flawless operation and quiet running be guaranteed. When the impeller and shaft are removed, a rubber bearing often adheres to the base of the impeller casing where it is very difficult to remove. JBL has produced a special tool for this purpose which is available at specialist pet shops under the name “Extraction tool for impeller bearing”. A useful cleaning brush for the impeller casing comes with the tool.

Re-starting the filter

Place the hose connection block with the attached hoses back in position as described in (2). Then turn the right-hand stopcock lever towards "OPEN" until the stop point. Repeat with the left-hand lever a few seconds later.

If the water does not begin to run into the filter automatically, start the filter as described in (5). Connect the filter to the mains power supply.

Stopcock on pump head stiff

Cause Solution
Washers do not glide	Dismantle hose connection block (7) and spray the stopcocks with commercially available silicone oil. Reassemble hose connection block and move stopcock backwards and forwards a few times.

Fish dead and/or water cloudy

Cause Solution
Nitrite poisoning due to too rapid change from “old” to “new”. Cleansing bacteria thrown away with old filter.	Run an old and new filter parallel for 2 weeks in the same aquarium or incorporate 1/3 of the old filter material in the new filter. Never carry out a “general clean up” of the aquarium at the same time!

Filter material for problem cases (available at your specialist retailer)

12 Filter material with foam edge

The following filter material kits are constructed according to a new two-stage principle which is specially designed for the CristalProfi Filter "e" range. They are comprised of a core section and an edge section. The core is made up of a relatively fine special filter media requiring a finely meshed net bag. The edge consists of coarse foam. With this design, the water flows slowly through the special filter media providing optimum efficiency, whilst at the same time the overall water flow through the filter is obstructed as little as possible thanks to the coarse foam edge. The size and volume of each kit is measured specifically for the filter basket of the JBL CristalProfi e range.

JBL CarboMec Pad

Kit with high-capacity active carbon

Removes residue medication, water discolouration and high molecular pollution from fresh water and salt water. Virtually no increase in conductivity and phosphate levels in the water.

JBL PhosEx ultra Pad

Solves algae problems by reliably removing phosphate

Prevents and eliminates undesirable algae growth by removing the main nutrient, phosphate, from fresh water and salt water.

JBL NitratEx Pad

Kit with nitrate eliminator

Eliminates nitrate from fresh water. Prevents and eliminates the growth of undesirable algae by reliably removing the nutrient, nitrate, from fresh water. Exchange resin can be regenerated with cooking salt.

JBL ClearMec Pad

Pollutant remover for crystal-clear water without algae trouble

A mixture of clay pellets and special resins removes the pollutants, phosphate, nitrate and nitrite, from fresh water, thereby preventing undesirable algae growth. The clay pellets promote colonisation by cleansing bacteria and additionally support the biological breakdown of pollutants. The result is crystal-clear, healthy water.

13 Filter material without foam edge

The following filter media hardly slow down the flow of water in the filter and therefore do not require foam edge. The amount contained in the pack is specifically measured for filter baskets of the JBL CristalProfi e range of filters.

JBL MicroMec

High capacity biological filter pellets

JBL MicroMec is a highly porous biological filter medium made from sintered glass and with a special surface and pore structure, which provides excellent conditions for colonisation by beneficial cleansing bacteria. This allows an effective biological breakdown of pollutants. It is therefore particularly well suited for intensive long-term filtration in freshwater and marine aquariums.

JBL CerMec

Ceramic rings

A mechanical filter medium which, though, also acts biologically as a result of colonising by cleansing bacteria. The ring shape makes it especially well-suited for directing water flow in all directions, thereby ensuring optimal flow through the filter.

JBL TorMec

Active peat pellets for natural tropical water

JBL TorMec Pellets are pressed from two peat components with differing amounts of humic substances. This produces a rapid initial effect and an evenly dosed long-term effect. JBL TorMec reduces the carbonate hardness and the pH level due to the high level of humic substances. It also helps prevent algae by slightly discolouring the water and therefore filtering out certain sections of the light spectrum, as in natural tropical waters.
