OPERATION
ALL MODELS
1. Connection:
a. Connect one line from isolated trunk line to pump outlet;
b. Connect second circulation line to the inlet of the tub.
2. Filling unit with glycol
a. Remove top deck / cover from the unit;
b. Fill the bath with 50/50 glycol and water solution up to 1” from the bath
top;
c. Replace top deck / cover unit;
d. Make sure all re-circulation lines are properly connected and turn the
pump motor on.
e. Liquid level will drop until circulation lines are full;
f. Refill with water approximately 1” from cover.
g. Temperature will slowly drop to 30°F. on thermostat/outlet gauge;
For MM-033:
h. Temperature will slowly drop to 34°F. on inlet temperature gauge;
i. Temperature on return line (inlet gauge) should be no more than 3° or 4°F
more than outlet gauge, if installation was done properly and quality trunk
line is used. If trunk housing is inside a PVC chase where there is water
present, it will cause large temperature differentials between the gauges;

MAINTENANCE
Keep liquid level constant in glycol reservoir. Glycol should be changed every two (2)
years except in very hot areas where it should be changed every year.
1. Check liquid monthly
a. If level is low, fill with water;
b. If ice builds up, remove one gallon of water and replace with glycol.
2. Keep condensing unit free of foreign matter and clean every six (6) months.

capacitor malfunction
B- Inadequate voltage
C- Compressor failure
A- Replace compressor relay,
overload or capacitor

drop below 90% of rated voltage.
C- Replace compressor
3- Compressor starts
and continues to run
until freeze up and
will not cut off.

4- Compressor does
not run but hums.
A- Inadequate voltage
B- Starting relay
malfunction
C- Compressor
malfunction
A- Measure voltage across
common and run terminal on
compressor. Voltage must not
drop below 90% of rated voltage.
B- Replace starting relay.
(Be sure to use correct relay.
Failure to do so will cause
compressor failure.)
C- Replace compressor

TROUBLESHOOTING
5- Warm beer A- Defective pump.
(Check motor also)
B- Defective motor.
(Check pump also)
C- Refrigeration unit is not
running.
D- Conduit lines located in
overheated area.
E- Conduit lines flooded in
PVC chase.
F- Un-insulated or poorly
insulated lines.
G- Thermostat.
H- Condenser fan motor
not working.
I- Freon leak.
J- Dirty condenser.
K- Condensation in conduit
isolation. (May be caused
from cleaning lines)
L- Warm walk in cooler
A- Check returns line in reservoir
for liquid flow. Replace pump.
B- Replace motor.
C- Refer to 2
D- Remove from any hot water
pipes or kitchen area with stove or
glass washer.
E- Remove lines from PVC,
thoroughly dry PVC and
repair/replace conduit as needed.
F- All lines should be fully
insulated from cooler to
dispenser, including glycol lines
from power pack into cooler.
G- Adjust temperature to colder
setting.
H- Replace condenser fan motor.
I- Repair leak and recharge.
J- Clean the condenser.
K- Check trunk housing in areas
for dropping or low spots. Split
insulation approximately 5” and
separate. Allow any water to
drain, and then air dry. Close and
seal trunk housing.
L- Refer to 1

Electronic Temperature Control with Display
Changing temperature units
Press the Up and Down buttons simultaneously to toggle between °F and °C.
Note: The keypad Lock jumper must be in the unlocked position (installed) before
adjusting the control. If the keypad is locked, pressing buttons has no effect on the
control.
Setting the SetPoint
Before setting the setpoint, be sure the control is set to the temperature units you want to
use, Celsius or Fahrenheit.
To view and adjust the setpoint, use the following method:
1. Press & hold the Menu button for about (2) seconds until the display changes to
flashing SP;
2. Press the Menu button again. The current setpoint is displayed;
3. Press the Up or Down button to adjust the setpoint temperature;
4. Press the Menu button to save. The display then returns to the sensor temperature.
Note: If the Menu button is not pressed after changing the setpoint, the control
reverts to the setpoint previously programmed into the A419.
Function Ranges and Settings
Display Function Range Factory Setting
SP Setpoint -30 to 212°F
(-34 to 100°C) 30
dIF Differential 1 to 30° (F or C) 3
ASd Anti-short Cycle Delay 0 to 12 minutes 2
OFS Temperature Offset 0 to 50 ° (F or C) 0
SF Sensor Failure Operation 0 = Output off
1 = Output on 0

Note: Operation at Extremes: If the combination of setpoint plus or minus the
differential falls outside the temperature range (-30°F to 212°F [-34°C to 100°C]), the
A419 operates as fallows:
Cooling/Cut-in: If setpoint minus differential is less than -30°F (-34°C), the control
switches on at setpoint and off when the temperature drops below -30°F (-34°C).
Heating/Cut-in: If setpoint plus differential is greater than 212°F (100°C), the
control switchs on at setpoint and off when the temperature exceeds 212°F (100°C).
Cooling/Cut-out: If setpoint plus differential is greater than 212°F (100°C), the
control switchs on when the temperature exceeds 212°F (100°C) and off at setpoint.
Heating/Cut-out: If setpoint minus differential is less than -30°F (-34°C), the control
switches on when the temperature drops below -30°F (-34°C) and off at setpoint.
Setting Other Functions
To set Differential (dIF), Anti-Short Delay (ASd), Temperature Offset (OFS) or
Sensor Failure, use the following method:
Order of the Functions
1. Press and hold the Menu button until the display changes to flashing SP. This
will take about two (2) seconds;
2. Press the Up or Down button repeatedly until the desired function is
displayed;
3. Press the Menu button to display the function’s current value;
4. Press Up or Down button until the desired value is displayed;
5. Press the Menu button to save the new value. The display then returns to the
sensor temperature.
NOTE: if you do no press the Menu button after setting the new value, the control
reverts to the previously programmed value for that function.

Checkout
Before applying power, make sure installation and wiring connections are according to
job specifications. After necessary adjustments and electrical connections have been
made, put the system in operation and observe the control for at least three (3) complete
cycles before leaving the installation.
Troubleshooting
If the control system does not function properly, verify that the unit is wired, configured
and set properly. If the problem persists, use the following procedures to determine the
cause of the problem:
•Check for proper supply voltage to the A419 control.
WARNING: Risk of Electrical Shock.
High voltage may be present at electrical terminals and other
exposed internal metal surfaces. Avoid contact with all metal
surfaces on control when cover is removed.
oRemove the cover by loosening the four captive cover screws;
oUse a reliable AC voltmeter to check the voltage between COM and 120V
or 240V terminals on line voltage models and the two (2) 24V terminals
on low-voltage models;
oThe voltage must be between 20 and 30 VAC for 24 volt application, 102
and 132 VAC for 120 volt applications, 177 and 264 VAC for 208/240
volt applications.
If the voltage reading is not within the required range, check the power source and
input power wires for problems.
