I. Introduction
The Advantage Controls Glycol Feed Systems are design to regulate pressure in closed loop Hydronic
Heating and Cooling applications.
Advantage Controls micro-processor base controller reads a solid state pressure transducer, displays
system pressure, and uses a keypad for the entry of control parameters. The micro-processor has built
in real-time clock and memory back-up for all user settings, in case of power interruptions. Setting for
all functions are made using the keypad, readings are displayed on a back lit 16 character alphanumeric
display.
Advantage Controls Glycol Feeders are stand alone pre-wired, pre-plumbed systems designed for ease
of installation. Our systems are mounted on a powder coated steel frame with anchor points.

III. Installation
Electrical Wiring
The standard digital glycol feeder controller has an internal regulated power supply that will operate in
the range of approximately 100 to 250 VAC on the incoming wiring. Output relay(s) are protected with a
replaceable fuse. Each relay’s output voltage will equal incoming line voltage. The Standard prewired units
are supplied with a 8 foot, 16 AWG, 3 wire grounded, 120 VAC USA power cord for incoming power.
NOTE:Liquidtightttingsandlabeledsignalleadcablesareprovidedforallsignal(lowvoltage)
connections,lowdrumlevelandpressuretransducer.
WARNINGS:
1. The controller should be connected to its own isolated circuit breaker, and for best
results, the ground should be a true earth ground, not shared. Wiring must be done
according to all applicable local codes.
2. Power(linevoltage)mustbedisconnectedwhilemakinganyconnections.Ifpoweris
suppliedtotheunit,linevoltagewillbepresentontherelaycards.
3. Lowvoltagesignalwires(transducer,level,alarm,etc.)shouldneverberuninconduit
withhighvoltagewires.
Mounting Instructions
Select a mounting location that provides the operator easy access to the unit and a clear view of the controller.
The location should be convenient to grounded electrical connections and system plumbing connections.
Mount the glycol feeder stand to a level concrete pad using the ½” mounting holes in the base of the stand.
Concrete pad construction and anchoring bolts must comply with local building codes. The required sample
line plumbing should be connected to the return header of the Hydronic system
WARNING:
Avoid locations that expose the controller to direct sunlight, vapors, vibration,
liquid spills or extreme temperatures; less than 0°F (-17.8°C) or greater than 120°F (50°C).
EMI(electromagnetic interference) from radio transmissions and electric motors can also

2. Check plumbing as it may have become loose from vibrations during shipping.
3. Fill Tank
4. Open isolation valve to system.
5. If there are no leaks verify that the pressure gauge agrees with system pressure. This value may vary do to
connection to Hydronic systems placement.
6. Before applying power to the controller, remove fuse from lower relay enclosure. (There will be two (2) fuses
on dual pump system) Reasoning behind this is, factory settings may not agree with your system and this
gives time for you to set your parameters before applying power to the pump or pumps.
7. Apply power to your system. Plug it in.
8. Once you are familiar with the controller from either reading the instruction manual or trial and error. Proceed
with setting perimeters that are correct for your hydronic system.

Description of Menus
NanoTron controllers have three modes of operation, Run, Menu and Force. All menus are circular. Pressing the DOWN
key will display the next line of information on the display.
Run- This mode is for normal operation. The control relays will only be automatically active in this mode. In the
status.
The Run menu will display values such as day, time, date and other values depending upon the features
present on the unit. The unit will automatically return to the Run mode if no keys are pressed for three
minutes.
Menu - This mode is used to make adjustments to settings and readings on the controller. To access the Menu
mode from the run screen, press the Menu key. Use the up or down arrow to scroll through the various
menu you will be able to step through that menu’s options with the up or down arrow key.

VIII. Troubleshooting & Maintenance
The Advantage Glycol Feeder is designed for many years of trouble-free operation. Should a problem occur,
refer to the following to help identify the problem.
NO POWER TO CONTROLLER
1. Disconnect plug from live receptacle.
2. Remove keypad panel to access relay board in the back of the enclosure (see page 6).
3. Locate green 3 position connector in bottom right corner of board and make sure it is securely plugged in with all three
wires tightly screwed down in the connector.
4. Locate logic ribbon cable on left side of relay board and make sure it is securely connected at both ends.
5. Before replacing the panel, do a quick visual of all connections and wiring to ensure no other damage has occurred.
6. Replace panel and secure.
7. Plug in power cord and proceed with Start-up.
8. If power issue was not corrected. Record Model /Serial Numbers and call customer service at 918-686-6211.
PUMP DOES NOT RUN WHEN RELAY INDICATOR IS ILLUMINATED
1. Check fuse and that the fuse holder is secure.
2. Check pump wiring.

• If No, inspect wire for damage. If no damage visible inspect internal wiring (see page 6).
3. If no resolution is found, record Serial / Model numbers and call customer service.
LOW LEVEL ALARM STAYS ON

replacement for older models that used a gear pump. The newer pumps may require a new larger suction strainer assembly
and tubing. Here are the models and required suction sizing based on the Pump selection code in the model number (see
model numbering on page 3):
Pump Code Replacement Suction Assembly
1 GFPUMP-1 GF-1-SUCTION includes ½” strainer and 3/8” tubing
2 GFPUMP-2 GF-2-SUCTION includes ½” strainer and ½” tubing
3 GFPUMP-3 GF-2-SUCTION includes ½” strainer and ½” tubing
4 GFPUMP-4 GF-4-SUCTION includes ¾” strainer and ¾” tubing

Maintenance
Maintenance and care will depend upon the usage and environment in which the system is subjected to. The
following is the suggested regular maintenance required to keep the glycol feed system operating properly:
TANK AND PLUMBING
Periodically check the piping and tubing to insure proper discharge of the glycol solution. The strainer should
be periodically checked for clogging and wear. The level wand should be removed and cleaned to prevent
clogging.
FEED PUMP
Check for proper operation. If any pump/motor noises, leaks or changes in operation are detected, the pump
PRESSURE RELIEF VALVE
Periodic checking and replacement of the adjustment seal is the only maintenance required.
13
IX. Manufacturer’s Product Warranty
Advantage Controls warrants units of its manufacture to be free of defects in material or workmanship. Liability
under this policy extends for 12 months from date of installation for all aspects of the glycol feeder with the controller
only covered for an additional 12 months. Liability is limited to repair or replacement of any failed equipment or part
proven defective in material or workmanship upon manufacturer’s examination. Removal and installation costs
are not included under this warranty. Manufacturer’s liability shall never exceed the selling price of equipment
or part in question. Advantage disclaims all liability for damage caused by its products by improper installation,
maintenance, use or attempts to operate products beyond their intended functionality, intentionally or otherwise,
or any unauthorized repair. Advantage is not responsible for damages, injuries or expense incurred through the
use of its products.
The above warranty is in lieu of other warranties, either expressed or implied. No agent of ours is authorized to
provide any warranty other than the above.
30DayBillingMemoPolicy
Advantage Controls maintains a unique factory exchange program to ensure uninterrupted service with minimum
downtime. If your unit malfunctions, call 1-800-743-7431, and provide our technician with Model and Serial Number
information. If we are unable to diagnose and solve your problem over the phone, a fully warranted replacement
unit will be shipped, usually within 48 hours, on a 30 Day Billing Memo. This service requires a purchase order and
the replacement unit is billed to your regular account for payment.
The replacement unit will be billed at current list price for that model less any applicable resale discount. Upon
return of your old unit, credit will be issued to your account if the unit is in warranty. If the unit is out of warranty
or the damage not covered, a partial credit will be applied based upon a prorated replacement price schedule
dependent on the age of the unit. Any exchange covers only the controller or pump. Electrodes, liquid end
components and other external accessories are not included.
