READ AND FOLLOW ALL

SAFETY INSTRUCTIONS

DANGER – To avoid possible electric shock, special care should be taken in the use of aquarium equipment. For each of the following sit-

uations, do not attempt repairs yourself; contact an authorized service facility for service.

1. A. If an appliance falls into the water, DON'T reach for it! First unplug it and then retrieve it. If electrical components of the unit get wet, unplug this equipment immediately.

B. If the equipment shows any sign of abnormal water leakage, immediately turn off power at main disconnect. C Carefully examine the equipment after installation.It should not be plugged

in if there is water on parts not intended to be wet.

D. Do not operate any equipment if it has a damaged cord or plug,or if it is

malfunctioning or if it is damaged in any manner.

E. To avoid the possibility of the plug or receptacle getting wet,position tank

to one side of a wall mounted receptacle to prevent water from dripping onto the receptacle or plug. A "drip loop",shown in the illustration at right should be arranged by the user for each cord connecting equipment to a receptacle. The "drip loop" is that part of the cord below the level of the receptacle or the connector, if an extension cord is used, to prevent water traveling along the cord and coming in contact with the receptacle.If the plug or receptacle does get wet,DON'T unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the appliance.Then unplug and examine for presence of water in the receptacle.

2. Close supervision is necessary when any equipment is used by or near children.

3. To avoid injury,do not contact moving parts or hot parts such as heaters, reflectors, lamp bulbs, etc.

4. Always unplug this equipment from an outlet when not in use, before putting on or taking off parts, and before cleaning.

Never yank cord to pull plug from outlet. Grasp the plug and pull to disconnect.

5. Do not use this equipment for other than intended use.The use of attachments not recommended or sold by the appliance

manufacturer may cause an unsafe condition. Do not install or stor

7. Make sure any appliance mounted on a tank is securely installed before operating it.

8. Read and observe all the important notices on the equipment.

9. If an extension cord is necessary, a cord with a proper rating should be used. A cord rated for less ampere or watts than the equipment

rating may overheat.Care should be taken to arrange the cord so that it will not be tripped over or pulled.

THE MARINELAND ML-24BW(2

)

This manual will provide you with the information you need to successfully operate and maintain your BIO-Wheel Live Seafood Display System.Please read it carefully and keep it for future reference.

The Marineland ML-24BW(2) is an easy-to-maintain refrigerated system for displaying and holding large loads of live seafood under ideal water conditions. Its dual mechanical/chemical filtration and powerful commercial BIO-Wheel wet/dry biological filter ensure optimum water quality at all times. And the compact plumbing design allows for convenient self-contained installation.

Your ML-24BW(2) system comes complete with everything you need to become fully operational:

Consumables: • Prefilter Pads (#CS1859)

• Carbon Filtration Pack (#CS1826)

• Biological Filter Material #2 (Dolomite: #C0402)

• Instant Ocean

Accessories: • Hydrometer (#CA1501)

• Thermometer (#CA1502)

• Lobster Rake (CA1503)

Lobster Salt (#CS0309)

NOTE:To prepare for the possibility of extra water changes, we recommend the purchase of additional Instant Ocean Lobster Salt (enough for two water changes).

Special Features…

• Reverse Flow Filtration prevents compacting of filter bed,ensuring cleaner water and eliminating the need

for periodic filter bed maintenance.

• The thermostatically controlled Refrigeration Unit is capable of maintaining tank temperatures of 45°–70°F and can

be preset to the exact temperature required by the system.

• The UV Disinfection Unit helps stop the spread of bacteria and disease throughout the system.Water enters the

UV Housing, where it is exposed to UV light.This exposure destroys the DNA of the organisms,preventing them from reproducing. After exposure, water exits and is returned to the system.

• The Protein Skimmer employs heavy aeration to remove dissolved organic matter from the tank in the form

of foam.The foam is flushed from the system and deposited into a floor drain or waste receptacle.

• Low Voltage Light Switch (located under display unit) allows you to turn fluorescent display light off during

non-business hours to reduce algae growth.

• The Sump Level Indicator Light glows red if water in the Sump drops below desired level.

Inside the ML-24BW

In this closed system, prefiltered water exits the enclosed Sump beneath the BIO-Wheel Filtration Modules and from there flows to the Water Pump. From here water is pumped either through the Protein Skimmer, through the UltraViolet (UV) Disinfection Unit, or into the display tank via spray bar or filter bed.

Water entering through the spray bars provides surface agitation while water passing up through the filter bed is pH-conditioned and chilled to proper temperature by the refrigeration coils.Water is drawn from the system through surface and bottom skimmers and is routed directly to the BIO-Wheel Filtration Modules.

As water passes through each module,mechanical and chemical filtration is provided by a polyfiber Prefilter Pad and Carbon Filter Pack. Filled with three lbs. of Black Diamond Premium Activated Carbon, the Pack adsorbs dissolved organic compounds which cause odor and discoloration.

(2)

System…

After passing through the Filter Media Trays,filtered water spills onto the BIO-Wheels mounted below. Because system flow causes them to rotate,the BIO-Wheels are constantly exposed to both water bacteria.This bioculture efficiently oxidizes all ammonia and nitrite on contact.

From the BIO-Wheels,prefiltered water re-enters the enclosed Sump for recirculation.

and air, thus developing a thriving culture of aerobic nitrifying

INSTALLATION

The following simple steps are required to get your system up and operational. Consult exploded views for any necessary clarification.

Tank Preparation

1. Locate unit near a 110–120 volt grounded outlet with a 20 amp dedicated circuit.

WARNING: Do not attempt to operate unit on extension cord or non-grounded circuit.

Do not handle or connect plug with wet hands.

2. Make sure Vented Panels are not obstructed. (to avoid overheating,we recommend keeping an adequate distance between the vent and any barriers to ventilation.) These panels allow cooling air to reach the compressor. They provide access to filters, thermostat, on/off switch, drains and other components.

3. Unpack all accessories, supplies and upper false bottom from tank.

4. Remove Vented Panels. Make sure system components are plugged into Junction Box.

NOTE: Cord receptacle outlets are labeled for clarity. If the cord becomes disconnected, be sure to reconnect to the designated outlet.

5. Attach Foam Drain Tube to drain outlet (shown) or skimmer cup.

NOTE: Because the Foam Drain Tube is designed to drain off excess liquids and foam from the Protein Skimmer, you will need to locate the tube over a bucket, container or floor drain.

6. Set Thermostat at 50° F. See pg. 17 for details.

7. Replace Vented Panels.

FILTRATION PREPARATION

IMPORTANT: Your system contains five types of filters:

1. Mechanical – Filter pads to screen out solid waste particles.

Chemical – Premium Activated Carbon to adsorb dissolved contaminants, discoloration, odors,toxic gases.

Biological – BIO-Wheels and Dolomite to remove toxic ammonia and nitrites

3. and help maintain pH balance.

Protein Skimmer to drive dissolved organic matter from water.

UV Disinfection Unit to eliminate waterborne bacteria, viruses and algae spores.

NOTE: Ammonia (produced from animal waste and respiration) is the biggest killer of aquatic animals. For this reason, biological filtration is critical.

A biological filter is a living filter...aerobic beneficial bacteria that consume animal waste products and convert toxic ammonia to non-toxic nitrate.When properly maintained, it keeps your product alive and healthy, your water clear.When a biological filter is overtaxed or abused, water clarity and product longevity will be affected.

Use of precultured BIO-Wheels (optional) means no need for a lengthy (6-8 week) break in period.Your bacteria culture is in place, ready to go to work.Product can be immediately loaded and displayed.

We recommend that you make an effort to keep your lobster population relatively constant. Beneficial bacteria breathe oxygen, but consume ammonia. No animals, no ammonia. No ammonia, no bacteria.

NEVER use soap or cleansers in or around tank. NEVER leave tank turned off for long periods of time. NEVER let a BIO-Wheel or gravel bed dry out.
