WARNING
2
HD-4- Black Diamond is designed to provide many years of safe and reliable service.
The installation, operation and maintenance instructions contained in the following
pages will insure your investment in your Black Diamond. Throughout this manual
there are safety warnings and cautions. Be sure to read and comply with all of these
warnings and cautions.
Do not operate the Black Diamond Filter until you have read and understand clearly
all the operating instructions and warning messages. The following instructions are
intended as a guide for initial general installation and initial operation. Be advised that
each installation may have unique conditions where the starting procedure can be
different. Failure to follow all operating instructions and warning messages can result
in severe injury, death, or property damage.
THE HD-4 BLACK DIAMOND FILTER OPERATES
UNDER HIGH PRESSURE
When any part of the filtering system is serviced, air can enter the system and
become pressurized upon restart of the system. Pressurized air can cause the lid to
blow off which can result in severe injury, death or property damage. To avoid this
potential hazard follow these instructions:
1. Turn off the pump BEFORE starting any service on the filter system.
2. Open the manual air relief valve located on the top of the filter. Wait until all
pressure is relieved before proceeding.
3. Whenever installing the filter tank clamp be sure to follow the Filter Clamp
Instructions Precisely.
4. Once filter system service is complete follow the System Restart Instructions
Precisely.
5. Maintain circulation system properly. Replace worn out or damaged parts
immediately.
6. Be sure the filter system is properly mounted and positioned according to the
instructions provided in this manual.
Never attempt to adjust, open or tighten any closures or lids or attempt to remove or
tighten any bolts when the system is pressurized or operating. This can cause a
separation or failure of filter components. Component failure will result in the instant
release of pressure causing component(s) to blow off at high velocities and to travel
far distances. Severe personal injury or death could occur if they were to strike a
person or persons.

WARNING: RISK OF ELECTRICAL SHOCK/
ELECTROCUTION
The Black Diamond Filter System must be installed by a qualified technician and
in accordance with all electrical codes and ordinances.
Always disconnect power to the filter equipment at the circuit breaker BEFORE
servicing the filter equipment. Make sure the disconnected circuit is tagged to
prevent accidental connection. Failure to do so could result in serious injury or
death due to electric shock.
Position the filter in such a way that the air relief valve will allow water to be drained
away from electrical connections. Water discharged from an improperly directed
valve can create an electrical hazard and cause severe personal injury as well as
property damage.
IMPORTANT SAFETY INFORMATION
•Have a trained pool professional perform all pressure tests.
•Do not connect the HD-4 Black Diamond to a Public Water System.
•All wiring, grounding and bonding of equipment must meet local and/or national
electrical codes.
•A check valve installed ahead of filter system will prevent filter contents from
draining back into pool.
•A check valve installed between filter and heater will prevent hot water from
backing up into the filter and possibly damaging internal components.
•Piping/plumbing must conform to local/state plumbing and sanitary codes.
•Make sure all piping is adequately supported.
•Do not pressure test with an air compressor.
•Check local codes for restrictions on backwash or waste water piping.
•Trapped air in the system can create a hazardous condition. Be sure to purge all
air from the system before operating, testing or servicing the equipment.

ABOUT YOUR HD-4 BLACK DIAMOND SYSTEM
Diatomaceous Earth DE Filters have always been renowned for providing crystal
clear pool water. Cartridge filter systems have been popular for their convenience and
ease of maintenance. With the HD-4 Black Diamond you get the best of both worlds.
The HD-4 Black Diamond Element Filtration System features 4 easily accessible
and removable elements. When water passes through these elements, impurities
such as dirt, algae and even some forms of bacteria are filtered out, producing
sparkling clear water.
The HD-4 design dramatically increases the filter’s internal surface area , giving you
much greater cleaning capacity per cycle, all without an increase in the tank size.
Maintaining your HD-4 Black Diamond could not be easier. You can choose any one
of two easy methods to clean your filter. The first choice is to remove and rinse off the
elements. The second and most popular choice is to remove the tank lid, open the
drain plug and simply rinse the elements in place.
The HD-4 Black Diamond design will even save you money because water flows so
efficiently through the filter that your pump will use less energy.
The combination of four Black Diamond elements in a single tank design means
better performance and much longer filter cycles. Longer cycles mean less cleaning
and maintenance. Because the Black Diamond elements remove the tiniest of
contaminants you can be assured of clean, crystal clear water for many years to
come.

blowing off during initial startup, restart or filter operation.
BEFORE working on the Filter System complete the following steps.
•Turn the pump off and shut off any automatic controls.
•Open the air relief valve and wait for the pressure to be relieved.
1. Make sure the lid O-Ring is in position in the lower tank half. Press the filter lid over
the lower tank half sandwiching the O-Ring between the 2 halves.
2. Keeping the ends of the filter clamp apart, position the center of the filter clamp
(the valley of the clamp) over both the upper and lower tank flanges. Carefully bring
the ends together as you insert the T-bolt into the union located on the other side of
the clamp assembly. (see diagram below)
3. Place the washer and the tension spring on the barrel nut. Place the second washer
on the T-bolt. Hand tighten the nut. Keep checking the clamp for proper seating as
you hand tighten the nut.
4. Tighten the nut using a 7/8 inch wrench. Be sure to tap around the outside of the
clamp using a mallet or similar tool (do not use a metal hammer) to ensure proper
seating of the clamp. Continue tapping and tightening until the coils in the spring touch
each other. Do not tighten beyond that point.
5. The spring coils should be checked periodically – about once a month – to ensure that
they continue to touch each other, indicating that the clamp is under sufficient tension.
If they do not touch repeat step 4.

QUICK REFERENCE TROUBLESHOOTING
PROBLEM
CORRECTION
AIR ENTERING THE FILTER SYSTEM
The following conditions in your filter system that allow air to
enter and corrections for each condition:
1. Due to low water level in pool, skimmer doesn’t have enough water in it and
pump pulls in air along with an insufficient amount of pool water.
•Raise water level in pool.
2. Air bubbles and/or low water level in pump’s hair and lint trap.
•Check and raise water level in pool.
•Skimmer basket is clogged with debris – clean it out.
•Cracked/split suction cleaner hose – replace hose.
•Leak in pump hair and lid – lubricate lid/replace lid.
•Leak in pump suction line – replace line.
3. Air bubbles coming out of pool return line.
•See 1 and 2 above.
4. Air is discharged from the air relief valve when the valve is opened and the
pump is running.
•See 1 and 2 above.
PROBLEM ELEMENTS LIMING UP
CORRECTION
A stiffening of the elements’ fabric caused by mineral deposits
in the pool water. This is usually due to excessive deposits of
magnesium, calcium or both.
1. Removal of the mineral deposits can be done by soaking the elements in a
solution of 6 parts water and 1 part muriatic acid.
PROBLEM SHORT FILTER CYCLES
CORRECTION
This is normal until the water in the pool has been initially
cleaned.
1. Elements may be loaded with debris, oils, etc. Clean elements thoroughly.

11
PROBLEM PRESSURE DROPS IN GAUGE
CORRECTION
If pressure drops on pressure gauge turn off the pump and
make sure any automatic controls are turned off as well. Turn
the motor shaft with your fingers. If it turns freely then the
pump needs to be disassembled to check the impeller for
clogs. If the impeller is not clogged and the shaft is not frozen
(it moves freely) then there is an obstruction in the plumbing
between the pool and the pump.
PROBLEM PRESSURE REMAINS HIGH AFTER BACKWASHING
CORRECTION If pressure remains high after backwashing the filter, backwash
again. If still high you need to check for Liming (see Liming – up).
PROBLEM
CORRECTION
Check the internal components of the filter.
1. Inspect the elements for any tears or holes.
2. Inspect the internal air bleed sock for any tears or improper installation.
3. Inspect the elements and make sure they are seated properly between the
upper and lower manifold.
