Quick Install for your Aqua Logic Delta Star Heat Pump
Unpack your Delta Star Heat Pump:
•Carefully remove the Heat Pump from the box by reaching underneath the Heat Pump
and lifting it by its base. NEVER lift the Heat Pump by its cover to avoid personal injury or
damage to the Heat Pump (See illustration).
•Use a Phillips head screwdriver to remove the two screws on opposite ends of the cover.
Place your Aqua Logic water Heat Pump:
•Place the water Heat Pump on a sturdy flat surface.
•Make sure that the unit is resting on its base to avoid damage.
•If you place the Heat Pump in a cabinet, allow at least ½” of space between the Heat
Pump and the walls of the cabinet to avoid vibration and noise.
Delta Star Plumbing:
•Your Aqua Logic flow-through Heat Pump requires an external water pump (not supplied)
for proper operation.
•The Heat Pump should be the last piece of equipment in the plumbing before the water is
returned to the tank or sump (after pump and filters).
•Use male-pipe-thread (MPT) fittings of the diameter below to connect your Heat Pump to
your system. Use the same or larger diameter pipe or hose for your plumbing for best
water flow.
•We suggest installing unions and ball valves (not included) on the inlet and outlet of the
Heat Pump for easier installation and removal of the Heat Pump from the system for
maintenance or repair (if necessary).
•Be sure that the water flow through your Aqua Logic Heat Pump goes into the water inlet
(bottom) and out the top to prevent potential damage (see illustration).
•If you use flexible hose to plumb your system or connect your Heat Pump, make sure
that the hose is not kinked to prevent restricted flow and potential damage to your Heat
Pump.
•Avoid elbows in your plumbing to minimize flow loss through your system.
•For most efficient operation, we recommend the minimum and maximum flow rates listed
in the specifications sheet for each model.
•Do NOT operate the Heat Pump without adequate water flow.
Electrical Hookup:
•We suggest using a dedicated power circuit for best operation and longest life of the Heat Pump. The circuit must be rated to handle the maximum
load of the Heat Pump.
•We highly recommend that you use a ground-fault interrupter (GFI) to avoid electrical shock. You can obtain an inline GFI from Aqua Logic, a local
hardware store if the outlet in the wall does not have a GFI installed.
•Avoid using an extension cord on your Heat Pump.
•Temperature controller installation:
oFollow the instructions included with the controller to install it.
oInstall the sensor for the controller “upstream” (ahead) of Heat Pump.
oPlug the Heat Pump into the controller.
oPlug the controller into the wall outlet.
oProgram or adjust the controller to your desired temperature. (see Heat Pump Controller Programming)
Your Aqua Logic Heat Pump is now installed and ready for operation!

The LCD display provides a constant readout of the sensor temperature and indicates if the output relay is energized. When the S1 or S2 annunciator is
constantly illuminated during operation, the relay is energized. The display is also used in conjunction with the keypad to allow the user to adjust the set
point temperature, differential and heating /cooling modes.
Programming Steps and Display
The control can be programmed in four simple steps using the LCD display and the three keys on the face of the control. (See photo for display and
keys.)
NOTE: Stage 1 must be set for heat mode and Stage 2 for cool mode for correct operation.
1. To start programming, press the SET key once to access the Fahrenheit/Celsius mode. The display will show the current status, either Ffor
degrees Fahrenheit or C for degrees Celsius. Then press either the up arrow or down arrow key to toggle between the For C designation.
2. Press the SET key again to access the heat mode set point temperature. The LCD will display the current set point temperature and the S1
annunciator will be blinking to indicate that the control is in the set point mode. Press either the up key to increase or down key to decrease the
set point to the desired temperature.
3. Press the SET key again to access the heat mode differential temperature. The LCD will display the current differential and the DIF 1 annunciator
will be blinking to indicate that the control is in the differential mode. Then press either up key to increase or the down key to decrease the
differential to the desired setting (minimum 1˚F, maximum 30˚F).
4. Press the SET key again to select heat mode. The LCD will display the current mode: C1 or H1. Then press either up key to increase or the
down key to select the correct Stage 1 mode. Stage 1 MUST be in the H1 mode for correct operation.
5. Press the SET key again to access the chill mode set point temperature. The LCD will display the current chill set point temperature and the S2
annunciator will be blinking to indicate that the control is in the set point mode. Then press either the up key to increase or down key to
decrease the set point to the desired temperature. S1 and S2 should both be set for the same temperature.
6. Press the SET key again to access the chill mode differential temperature. The LCD will display the current differential and the DIF 2 annunciator
will be blinking to indicate that the control is in the differential mode. Then press either up key to increase or the down key to decrease the
differential to the desired setting (minimum 1°F, maximum 30˚F). DIF1 and DIF2 should both be set to the same value for best results.
7. Press the SET key again to access the heating mode. The LCD will display the current mode: C2 or H2 Stage 2 MUST be in the C2 mode for
correct operation.
8. Press the SET key again to exit programming mode. Controller will display current water temperature.
Controller will automatically drop out of “program mode” and return to “operating mode” 30 seconds after last key press.
Troubleshooting Controller Error Messages:
Display Messages
•E1 - Appears when the up or down key is pressed when not in the programming mode.
To correct: If the E1 message appears even when no keys are being pressed, replace the control.
•E2 - Appears if the control settings are not properly stored in memory.
To correct: Check all settings and correct if necessary.

When Disaster Strikes
You may have a lot of money invested in your aquarium at home or in the office. Or you may have valuable
dollars invested in seafood for your store or restaurant. Unfortunately, equipment or electricity may fail at the
most inopportune time. What can you do to minimize the risk in such an event? Based upon our years of
experience in the aquatic life support industry, we recommend the following:
•Always have ALL of the electrical equipment connected to ground fault interrupt (GFI) circuits.
•Do not overload electrical circuits.
•Add the aquarium system and livestock to your homeowner’s or renter’s insurance policy if allowable.
•Monitor your system closely during the first few weeks of operation. Make sure that everything is working correctly. Call it a
shakedown cruise.
•Check the condition of your equipment regularly. Keep it clean. You don’t take your car on a long trip without first changing
the oil, checking the tires, etc. Why would you ignore maintaining the equipment on your aquarium?
•Keep blue ice or bags of ice in the freezer. If you use ice to help maintain water temperature, leave the ice in the bag so that
the water from the melting ice doesn’t dilute the water solution in your aquarium.
•Turn off aquarium lights if the Heat Pump fails. Livestock in the wild have periods of several days when they do not get
intense light. There ARE typhoons that can cover an area for days at a time. Limited use of VHO and halide lamps to avoid
heat build-up in the tank is far less harmful than extremely high water temperatures.
•Put a temperature controller on the lights to shut them off and to sound off an alarm if water temperature rises more than 5°F
above the Heat Pump set point.
•Keep a spare pump on hand in case your primary pump fails.
•Maintain a supply of ammonia-neutralizing chemicals such as Amquel. You can use them to control ammonia in your system
during a prolonged power outage. Be sure to follow manufacturer’s dosage recommendations and compatibility with
organisms in your tank.
•Stock your aquarium sparingly. Then when disaster strikes (and it usually will sooner or later), you have more time to fix the
problem before you lose livestock.
•Oversize your filtration system. Water quality is the most critical element for maintaining healthy fish. On a reef tank, it is easy
to invest thousands of dollars for livestock (not including how sentimental you may be attached to your livestock). Why not
spend a little more up front for more life support reserve in case of a disaster?
•Have a battery-powered air pump on hand for extended power outages. It will provide aeration and move water in the
absence of power.
•In most areas of the country, our electrical grid is subjected to surges, spikes, brownouts and blackouts caused by high peak
usage, snowstorms, hurricanes, thunderstorms and more. A surge protector can help with the surges and spikes but they are
not effective in brownouts. Furthermore, even the best surge protector can’t protect against direct strikes of lightning. It takes
an uninterruptible power supply (UPS) or backup generators to protect against low voltage and blackouts. And it takes a
backup generator to adequately power a Heat Pump—especially a ½-HP unit needed on a 300-gallon tank.
It is very unfortunate when equipment fails. However, a prudent aquarist should have a disaster plan and follow the motto, “Be
prepared.”

Maintenance and Cleaning
Your Aqua Logic Heat Pump should provide years of efficient and reliable service with a minimum amount of
maintenance. There is no scheduled maintenance and there are only two procedures that can be performed
by the user.
Cleaning:
The condenser should be cleaned occasionally to remove accumulated organic material or minerals from the coil. To see whether the
condenser needs to be cleaned, shine a flashlight through in the water inlet side of the Heat Pump.
You may also need to remove accumulated organic material or minerals from the coil (Evaporator). Organic material may be removed
by using a mild chlorine bleach solution while minerals may be removed by using a dilute muriatic acid solution, Lime-A-Wayor other
hard water deposit remover.
Warning:
•Do NOT perform both procedures at the same time since the combination of chlorine and acid may cause serious injury or death.
•Be sure to wear appropriate protective gear.
•Use extreme caution when using caustic chemicals around your system.
To remove accumulated organics (slime):
•Remove power from the Heat Pump.
•Wear protective eyewear, clothing and gloves.
•Mix a solution of 1 part unscented chlorine bleach to 4 parts water.
•Use a small pump, pail and hoses to run the solution through the heat exchanger for about 10 minutes to flush the organic
materials out.
•Rinse the heat exchanger with clear unchlorinated water until you can no longer smell chlorine.
•Allow the heat exchanger to dry and then return the Heat Pump to service.
To remove accumulated minerals:
•Remove power from the Heat Pump.
•Wear protective eyewear, clothing and gloves.
•Prepare a solution according to cleaning product instructions.
•Use a small pump, pail and hoses to run the solution through the heat exchanger for about 10 minutes to flush the minerals out.
•Rinse the heat exchanger with clear unchlorinated water for at least 30 minutes.
•Allow the heat exchanger to dry and then return the Heat Pump to service.
