INSTALLATION AND OPERATION

1.  Remove packaging from the unit in the vicinity of the area where it will be installed.

2.  Carefully lift the unit into the desired position.

NOTE: DO NOT PUSH OR SLIDE UNIT – Damage will be caused to the legs if the unit 

is pushed into position.

PLACEMENT

•  It is not recommended to install a power pack on top of a walk in cooler.

•  It is not recommended to install a power pack outside.

•  Always ensure a minimum clearance of 18 inches above and in front of a power pack. This allows 

  for proper air flow around unit.

•  Ambient operating temperature range is 50-90° F for all air cooled models.

•  Power pack must be wired to a ground fault circuit interrupter per UL guidelines.

INSTALLATION STEPS

(MMPP4301-EP)

(Assure tower connections are complete.)

  1.  Connect one of the glycol tubes to the pump inlet. Insulate any exposed tubing.  
  2.  Connect the second glycol line to the pump outlet. Insulate any exposed tubing. 
  3.  Carefully push the glycol bath lid to one side, allowing sufficient space to fill the bath with liquid.

Micro Matic Polar Flo

®

 glycol solution 

(mixed 2 ½ parts water to 1 part glycol).

Fill the bath to the full level on the glycol level indicator.  

  6.   Connect unit to the electrical outlets capable of handling the required voltage loads.  This should be    

carried out by suitably trained personnel and comply with all state and national electrical codes.

  7.   Glycol level will fall as glycol is pumped through the glycol lines. Continue to fill the bath to the fill level 

on the glycol level indicator.  

  8.  Replace top cover.
  9.  Inspect for any leaks.
10.  Glycol temperature will fall slowly to 29° F.

NOTE: To adjust the glycol temperature, please see Adjusting Electronic Thermostat.
