125', 250', 350' AND 500' UNITS
INSTALLATION STEPS
(Assure tower connections are complete.)
1. Remove the refrigeration deck from the unit.
2. Inspect the glycol tank for any debris.
3. Connect one of the glycol lines from the trunk line to the pump outlet. Insulate any exposed tubing.
NOTE: In units with more than one pump, connect a glycol line to each pump outlet.
4. Connect the second glycol line from each circuit to the glycol bath inlet.
5. Fill the glycol bath with Micro Matic Polar Flo glycol solution:
• 125', 250' and 350' units: 2 ½ parts water to 1 part glycol.
• 500’ unit: 1 part distilled water to 1 part glycol.
Fill bath to the level of the ll line on the glycol level indicator.
6. Replace the refrigeration deck.
7. Remove electrical outlets capable of handling the required voltage loads. This should be carried out by
suitably trained personnel and must comply with all state and national codes.
8. Glycol level will fall as glycol is pumped through the glycol lines. Continue to ll the bath to the full level
on the glycol level indicator.
9. Inspect for any leaks.
10. Temperature of the glycol will fall slowly to 29°F.
NOTE: To adjust the glycol temperature, please see Adjusting Electronic Thermostat.
MAINTENANCE
1. Inspect the unit monthly to ensure that the glycol level is maintained to the full level.
2. If the level is low replace with a Micro Matic Polar Flo glycol solution:
• 75', 125', 250' and 350' units: mixed 2 ½ parts water to 1 part glycol.
• 500' units: 1 part distilled water to 1 part glycol.
3. If there is evidence of ice build up in the unit, allow the ice to melt and replace all the water/glycol
solution with a fresh solution mixed per above instructions.
4. The glycol/water solution should be changed approximately every 18 months. In regions of high humidity
considerations should be given to replacing the solution on an annual basis.
5. Check and clean the condenser ns every sixty (60) days.
6. Check that there is adequate air ow through the unit ensuring enough space all around and that there
are no obstructions in front of the air ow vents.
7. Check the condition and effectiveness of the trunk line insulation.
8. At regular intervals, to be determined by the owner, the unit should be checked for electrical safety.
