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 16 character keyboard for the entry of control parameters. The micro-
processor has built in real-time clock and EEPROM back-up for all user settings, in case of power
interruptions. Setting for all functions are made using the keyboard, 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:Liquidtightttingsandlabeledsignalleadcablesareprovidedforallsignal(lowvoltage)
connections,lowdrumlevelandpressuretransducer.
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(linevoltage)mustbedisconnectedwhilemakinganyconnections.Ifpoweris
suppliedtotheunit,linevoltagewillbepresentontherelaycards.
3. Lowvoltagesignalwires(transducer,level,alarm,etc.)shouldneverberuninconduit
withhighvoltagewires.
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
causedamageorinterferenceandshouldbeavoided.

Start Up and Test Procedure / Recommendations
1. Beforellingtank,besurethatthetankandthelterbowlarefreeofpackingmaterialandor
construction debris.
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.

VIII. Troubleshooting&Maintenance
The Advantage Glycol Feeder is designed for many years of trouble free operation. Should a problem occur,
refer to the following chart to help identify the problem. If replacement is required, follow the procedures
listed in the Warranty and Factory Service portion of this manual.
NO POWER TO UNIT, POWER PRESENT AT RECEPTACLE
This happens if the power cord is tripped over or gets caught and pulled by accident.
1. First disconnect plug from live receptacle.
2. Next you will need Phillips #2 driver to remove face plate
 3. Faceplatesaresnugttinganditmayrequireasmallstandarddriverintheslotatthesideofthepaneltoget
it moving.
4. Once the panel is free, let it hang down out of view of the enclosure opening.
5. Locate the connector inside of the enclosure for power this is a GREEN three (3) terminal with screw downs.
6. Reconnect to RELAY / POWER BOARD (Drawing on page 20)
7. Before replacing the panel, do a quick visual of all connections and wiring to ensure no other damage has
occurred.
8. Replace panel and secure.
9. Plug in power cord and proceed with Start-up.
10. Your power issue was not corrected.
Record Model /Serial Numbers and Call Customer Service 1 [phone].
PUMP WILL NOT RUN. BLOWS FUSE WHEN ENERGIZED
This usually is cause by having some debris in the gears of the pump.
1. Before removing the pump head loosen the six head screw a half turn.
2. Replace blown fuse and energize pump.
3. If this corrects issue, de-energize pump, tighten six screw, proceed with Star-Up.
4. If this doesn’t solve issue the pump head should be removed and inspected for particles.
Because of tolerance in the gears it doesn’t take a big particle to freeze the motor.
5. Before removing the head be sure to close the suction line valve.
6. It is not necessary to remove tubing.
7. Remove the six (6) head screws.
8. Be aware of the seal ring as you remove the head.
 9. Withyourngersturnthegearstoinsurethatthemotorisnotseized.
10. If the gears turn freely you may power the pump for a short period to prove rotation.
11. If the gears do not turn freely, but they do turn, try powering the pump for short period.
12. If there is rotation. Replace the Pump Head, being careful to align gasket.
13. If the pump motor is frozen, it is best to replace the entire pump.

3. With pressure at zero press ENTER.
4. Controller will than display CALIBRATE.
5. Open Isolation Valve to reestablish pressure to Sensor.
6. Press enter and key in correct pressure.
7. Press enter key and the correct value should display after brief moment.
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.
GEAR PUMP
Check for proper operation. If any pump/motor noises, leaks or changes in operation are detected, the
pumpshouldberemovedandexaminedbyacertiedtechnician.Gearpumprepairscanbedi󰀩cultand

andnullicationofthewarranty.Nolubricationisrequired.
PRESSURE RELIEF VALVE
Periodic checking and replacement of the adjustment seal is the only maintenance required.
