INSTALLATION
1) Floor drain, electrical and refrigeration stub-ups should be made compatible
with drawing prior to setting in place. Floor drain location is critical.
(Refrigeration stub-ups are for remote refrigeration).
2) Make certain that all light bulbs are set securely in their sockets as they can
potentially loosen during shipping and disconnect from the contacts. This will
cause arcing.
3) Connect all services.
4) Attach the bottom stainless steel skirts into the pre-tapped supports and seal if
required (see assembly instructions).
5) A Stark representative will set up the tank once electrical power and drains are
connected. Please call to confirm.

CARE AND MAINTENANCE
1) Never use any abrasive or ammoniated cleaners or sponges on acrylic parts.
They will scratch. Do not tape signs to the face. Do not use razor blades to
clean the face. Clean only with soft, damp paper towels.
2) Do not spray water on lights. They are connected to GFI circuitry to protect
against electric shock. If lights go off, there is a red reset button inside the
cabinet. Press it in to re-activate the lights.
3) Use stainless steel cleaners on stainless steel faces.
LOBSTER TANK
The lobster tank provides an environment that closely simulates the natural
ocean waters in which lobsters thrive. As a result, Stark Lobster Tanks keep more
pounds of lobsters alive for a longer period than any other closed system available
today. Proper care and attention will result in a tank that requires minimal water
changes, bio-gravel changes or chemical testing. However, it is important to
remember that the tank is an aquatic life-support system, which must be monitored
on a regular basis, even if no actual maintenance needs to be performed.
OPERATION
LOADING SCHEDULE: This Low-Maintenance system should never need a
water change, however, you must adhere to the loading schedule for six (6) to
eight (8) weeks! Lobsters excrete ammonia, which at certain levels, becomes toxic
and kills them. Therefore, it is extremely important to allow time for healthy
bacteria growth while increasing your lobster load. Bacteria are the single-most
important biological component of the tank, since its primary purpose is to consume
the life-threatening ammonia.
Lobsters must be healthy and not kept in a cooler.
Intentional overloads causing lobsters to die will necessitate a service call, and will
NOT be covered by your warranty.

BREAK-IN PERIOD: One of the key components of the Stark Filtration System is
the biological filter bed. During the initial installation and start-up process, the
Activated Sand for the sand filter will be introduced into the system. This will
commence the process of building up the level bacteria necessary for a solid
biological filter. We recommend that the following schedule be followed so that the
bed will be built up properly.
Week #1.......................30% of total product capacity in tank
Week #2.......................50% of total product capacity in tank
Week #3.......................75% of total product capacity in tank
Week #4.......................100% of total product capacity in tank
HANDLING OF THE LOBSTERS: Before putting new lobsters in the tank, they
should be purged if they have traveled over night in a dry pack. DO NOT place
hands into the tank, or handle the lobsters, after having washed hands with any type
of soap. Doing so will actually create a toxic environment for the lobsters and
ultimately kill them.
Purging Instructions: Use SALT WATER from the tank instead of preparing a
special cold salt water solution. Place small batches of lobsters into this solution for
no more than 3 to 4 minutes. Remove them and immediately put them into the
tank. Repeat this process, until all lobsters have been purged.

WATER LEVELS INDICATE HOW TANK IS PERFORMING
Water levels should be checked on a daily basis. The tank has 3 blue marks (I, II,
and III, respectively), which indicate various water levels. This will tell you how the
tank is performing (i.e... when to add salt water or change the filter).
MARK I - TANK WATER LEVEL
Located outside the tank, the salt water level must be maintained at this
mark. When the water level drops below one, add salt water to bring the level
back up. The filtration system will not work properly if the level of water is
below this mark. Pre-mix salt water as follows: Add 1 lb. (16 oz.) of Stark
Marine Crystals to 4 gallons of cold water. Mix well, and add slowly to tank.
MARK II - FILTER WATER LEVEL
Located inside the window, behind the pullout filter. When the water
level drops down to the mark, this indicates that the filter is dirty and needs to
be either washed or replaced (filter must be replaced after the third washing).
The red warning turn on. Monitor this level diligently, as the filtration system
will be compromised if the water is allowed to go way below this mark.

MARK III - PROTEIN SKIMMER WATER LEVEL
Located in the window behind the skimmer. The protein skimmer
removes the foamy protein lobster waste products found in the water.
Through this filtration process, the tank will lose water and the water level
will drop.
FLUIDIZED BED SAND FILTER
The lobster tank is shipped from the factory with sand, gravel, and the
water flow valve set at halfway. Adjust the valve until you see very slow
movement of sand, approximately ¾ full in the cylinder. The valve’s position
should NOT be changed. If the valve is opened too much, the sand will blow
out into the main tank area.

CLEANING: An effective means of keeping algae from accumulating on the
interior walls of the tank is to wipe the interior of the clear acrylic with a
clean, soft sponge. Periodic cleaning of the protein skimmer housing with a
baby bottle brush will prevent an accumulation of dry foam from blocking the
outlet pipe. The clear acrylic exterior display area should be cleaned with a
Plexiglas cleaner. NEVER USE WINDEX OR CLEANERS OF A
SIMILAR TYPE. Lemon Pledge or simply warm water is recommended. It
is also recommended that the LED display lights be turned off at night in
order to minimize the growth of algae. Stark has algae removing products...
call to order.
WARRANTY: Stark provides a one-year warranty on all mechanical parts of
the tank. During the term of the warranty, Stark will replace mechanical parts
deemed to be defective from the manufacturing process at no cost.

HELPFUL HINTS
SALINITY READING: The hydrometer should float with the surface of the
water in the top area that is shaded green. Too much salt in the tank will cause
the hydrometer to rise so that the green area is out of the water completely.
Too little salt in the tanks causes the green area to sink completely below the
top of the water.
SALT: Only the use of Stark Marine salt is recommended. Lesser quality
salts do not dissolve as well and do not contain all of the essential trace
elements that are necessary for the proper operation of Stark Tanks. Other
salts can cause erratic salinity in the water, burn the lobsters and bind the
pumps. In addition, too much salt may be added because the undisclosed
crystal of poorer quality salts will not show on the hydrometer reading. When
the salt eventually dissolves, the salinity level of the tank will rise, and the
skimmer will pump out more of the poor quality water. The water level will
drop, requiring additional water and salt to be added.
CLEAN the skimmer every week using a baby bottle brush. To clean inside
the chamber, open top white screw cap to gain access.
IF LOBSTERS MUST BE KEPT IN A COOLER, wash the lobsters in salt
water from the tank for three (3) minutes and cover lobsters with a salt water
soaked apron to seal them off from cold air blower. If lobsters have been in
cooler for more than 2 days, DO NOT put them into the tank.
USE ONLY the proper size pre-cut exact fit Stark Filter Pads, Marine Salt
Crystals and Carbon.
KEEP FILTER SCREENS FREE OF CLOGGING DEBRIS (the screens
are cone-shaped black plastic and are screwed into the bottom of the filter
box). Test these screens periodically for good suction.
CHANGE ACTIVATED CARBON approximately every four (4) weeks to
remove yellow color from the water. Frequency may vary.
NEVER add salt directly to the tank. Always dissolve salt well in a bucket (1
lb to 4 gallons of water) and add slowly to the tank.

SALINITY should be 1.022 - 1.025 as indicated on the hydrometer (Do not
allow salinity above 1.030).
TEMPERATURE of water for proper operation should be 46°F to 48°F.
ULTRA-VIOLET STERILIZER should be plugged in during set up and
bulb should be changed every 10-12 months. Stark stocks replacement
bulbs... call to order.
CLEAN OR VACUUM THE COMPRESSOR CONDENSING COIL if
your unit has one (in front of the compressor fan) every two months to remove
dust and dirt. Clean the exterior stainless steel register as well.
CLEAN THE EXTERIOR OF THE CLEAR ACRYLIC TANK with
non-abrasive cleaners such as Lemon Pledge, warm water, etc. Clean the
interior with a clean cloth weekly. DO NOT USE ANY CLEANERS
INSIDE THE TANK UNDER ANY CONDITION.
IN CASE OF A POWER FAILURE, remove lobsters from the tank and
place them in a cooler with a salt water soaked apron over them, to seal off
from the cold air blower. Once power is restored, allow the tank to reach
operating temperature of 46ºF - 48ºF before replacing lobsters.
NEVER DRAIN THE WATER FROM THE TANK. This system does not
require any water changes. Only in case of emergency (after talking with
Stark) would we recommend a water change. If necessary, use salt water (1 lb
salt to 4 gallons of water) to fill the tank.
Stark ships a 1 lb jar of chlorAm-x, which is used for start-up to keep the
ammonia level low until the biological system can handle the bio-load.
Add 4 oz to the tank water at start-up and 2 oz per week for four (4) weeks
for the typical 100-150 gallon tank.
Stark has included a package of algone to prevent the growth of green
algae in the tank. Add one (1) package every two (2) weeks in the filter
box. See instructions on the algone box.

DAILY CHECK LIST
1) If the water level in the sump tank is below the #1 line (it is normal for the
tank to lose salt water through the skimmer cleaning system), add salt water.
Mix in a bucket: 1 lb of Stark Marine Salt with 4 gallons of water, then pour
into the tank. NOTE: Never add undissolved salt or a large amount of
fresh water directly into the tank. It will harm the biological filter.
2) After the main water level is up to the MARK I line, check the filter box level.
If the water is at or below the MARK II line, or if the red light is on, clean or
replace the filter pad. Be sure filter completely covers the filter pull... NO
GAPS.
3) Check the water salinity. The hydrometer should float so that the top surface
of the water is in the top green area of the hydrometer. If the hydrometer is
floating too low (the top green line is below the water), add salt. If the
hydrometer is floating too high (the top green line is above the water), add
fresh water.
4) Check that the temperature is between 46ºF and 48ºF.
5) Clean and purge lobsters immediately after receiving them by putting some of
them in a five (5) gallon container of salt water from the tank for no more than
three (3) to five (5) minutes before putting them in the tank. Use water from
the tank to fill the container. Discard the purging water when finished; DO
NOT put back into the tank. Add salt water to the tank as necessary to return
the water level to the MARK I line.
6) Remove dead lobsters and lobster parts immediately. Never feed anything to
the lobsters.
7) Never wash or change the gravel/sand in the biological filter.

FREQUENTLY ASKED QUESTIONS
1) Why is the water level dropping?
During normal operation, the Stark filtration will automatically remove impurities
from the water before they cause an ammonia build-up in the tank. Water volume
displacement may also occur when adding and removing lobsters from the tank.
When you have the desired amount of lobsters in the tank at any given time, check to
see water levels are at the proper mark lines.
2) How much water should the tank be losing?
Upon initial start-up, the tank will be operating without a maximum strength
bio-gravel bed. As a result, water may need to be added daily, as needed, during the
first week of operation. The Biological Filter will get stronger each week. After
approximately six (6) to eight (8) weeks, the biological filter and the protein
skimmer will be working together, and water will be lost only on occasion. Refill as
needed.
3) What do I do if lobsters start dying?
Call Stark. One of ourexperienced technicians will work with you over the phone, or
via video conferencing, to help resolve the issue as expeditiously as possible. If is
determined that the issue cannot be resolved remotely, the Stark technician will
make a service visit to resolve accordingly.
4) How often should the carbon bags be changed?
Although the answer to this question depends on the amount of product that is being
moved through the tank, our general recommendation is to replace the 2 carbon bags
anytime you start to see a yellow discoloration of the water.

Dimensions
IMPORTANT: Use this A421 Series Electronic
Temperature Control only as an operating control.
Where failure or malfunction of the A421 control could
lead to personal injury or property damage to the
controlled equipment or other property, additional
precautions must be designed into the control
system. Incorporate and maintainother devices, such
as supervisory or alarm systems or safety or limit

Parts Included
Each A421 Control includes a Johnson Controls/
PENN® A99 Series temperature sensor. See A99
Series Temperature Sensors, Wiring, and Technical
SpecificationsformoreinformationaboutA99sensors.
A99 Series Temperature Sensors
The A421 controls require an A99 sensor, and each
A421 control includes an A99 sensor. Any A99 Series
sensor works with the A421 Series controls. Do not
replace an A99 Series sensor with any other brand,
series, or type of temperature sensor. See Ordering
Information for available A99 Series sensor models.
The sensor leads may be extended in the field. See
Table 1 for recommended wire sizes and lengths. On
long sensor cable runs, use shielded cable to reduce
Electro-Magnetic Interference (EMI). Observe EMI best
practices when routing sensor leads.
The A99 Series sensors are moisture tolerant and
splash resistant, but do not completely immerse the
A99 sensor in water or any other liquid. Immersing the
sensor can allow liquid to enter the sensor probe where
the stainless steel tube meets the wire cable and result
in sensor failure, which voids any warranty.
In applications where the sensor may be exposed to a
lot of moisture, splashing, or rain, we recommend
mounting the sensor in a vertical position with the cable
at the bottom routed downward to allow moisture to
drain away from the stainless steel probe. Use a
suitable bulb well for complete fluid immersion
applications. See Ordering Information for a
recommended bulb well.
The A99 Series sensors are positive temperature
coefficient (PTC) sensors. To test an A99 sensor,
disconnect the sensor from the control and measure
the resistance between the sensor leads:
• When the temperature at the sensor is 77°F
(25°C), the resistance should be 1,035 ohms.
• When the temperature at the sensor is 32°F (0°C),
the resistance should be 855 ohms.
See Troubleshooting for more information.
When an A99 sensor is connected to a standard
A421 control, the range of usable values is restricted
by the control to -40 to 212°F or -40 to 100°C.
See Wiring, Technical Specifications, and refer to the
A99B Series Temperature Sensors Product/Technical
Bulletin (LIT-125186) for more information regarding
A99 Series sensors.
Mounting
Observe the following guidelines when locating and
mounting an A421 control:
• Ensure that the mounting surface can support the
control, DIN rail, mounting hardware, and any
(user-supplied) panel or enclosure.
• Mount the control in a vertical, upright orientation
wherever possible. DIN rail mounting is strongly
recommended for Type 1 controls.
• In direct-mount applications, mount the control on
a flat and even surface.
Mount the control in a location free of corrosive vapors
and observe the ambient operating conditions listed in
Technical Specifications for both the A421 control and
the A99 sensor.
• Allow sufficient space for connecting and routing
wires, viewing the LCD, and using the touchpad.
• Do not mount the control on surfaces that are
prone to vibration or in a location where
high-voltage relays, motor starters, other sources
of electromagnetic emissions, or strong radio
frequency may cause interference.
• Do not install the control in an airtight enclosure.
• Do not install heat generating devices with the
control in an enclosure that may cause the ambient
temperature to exceed 150°F (66°C).
To mount a Type 1/IP20 control on DIN rail:
1. Provide a section of 35 mm DIN rail that is longer
than the control width, and mount the DIN rail in a
suitable location using appropriate mounting
hardware.
2. Clip the control module on the rail, position the
module’s upper DIN rail clips on the top rail, and
gently snap the lower clips on to the bottom of the
rail.
To direct-mount a Type 1/IP20 control to a wall or
other flat surface using the four keyhole slots:
1. Remove the enclosure cover, place the control
vertically against the wall surface in a suitable
location, and mark the keyhole slot locations on the
mounting surface.
2. Install appropriate screws or fasteners, leaving the
screw heads approximately one or two turns away
from flush to the mounting surface.

A421 Series Standard Electronic Temperature Controls Installation Instructions
3
3. Position the control mounting slots over the screw
heads, and then carefully tighten the mounting
screws to secure the control to the surface.
4. When mounting the control on an uneven surface,
use shims to mount the control evenly on the
surface.
Additional Guidelines for Mounting Type 4X/IP66
Controls
The Type 4X models may be mounted to flat vertical
surfaces using the four holes at the enclosure corners.
Place the control against aflat wall surface in a suitable
location, and mark the mounting screw hole locations
on the mounting surface. Use appropriate screws and
shims to mount the control evenly on the surface.
On Type 4X models, select the knockout to be
removed. Place a screwdriver blade on the knockout
near the edge. Apply a sharp blow to the screwdriver
handle to loosen the knockout. Be careful not to
damage the control’s interior components.
An additional low-voltage, two-wire cable is required to
operate the A421 control’s temperature setback (BIN)
function. On Type 4X/IP66 enclosures, you must install
a suitable watertight fitting in an available knockout to
pass the two-wire cable through the enclosure wall.
The control enclosure base on the Type 4X/IP66
models can be easily rotated 180º relative to the
control enclosure cover and LCD, allowing you to bring
the electrical connection to either the top or bottom of
the mounted control.
Note: Do not twist the wiring harness between the
enclosure base and cover more than 180º.
