START-UP AND OPERATION
Filling the system:
NOTE: Use only distilled or treated water in the coolant mixture to prevent scale build-up in
the cooling system and piping
NOTE: Do not overfill or under fill the reservoir. Running the Little Cooler with improper
coolant levels will damage the pumping system and void the warranty.
1. Remove the access panel on top of the Little Cooler.
2. Find and remove the plastic plug inserted into the reservoir cover to reveal the fill hole.
3. Fill the reservoir with a 50/50 mix of automotive (long-life, low silicate) antifreeze and
distilled water. The system will hold 7 to 8 gallons (depending on your piping length). The
reservoir is full when liquid is visible in the sight glass.
4. Start the system. After 5 minutes of operation, check the level of liquid in the sight glass.
Top off the reservoir if the coolant level is low.
5. Reinstall the plug into the fill hole and replace the Little Cooler’s access panel.
Operation:
1. Once installed, the little cooler requires minimal operator involvement.
2. Check the level of coolant in the sight glass. Top off if necessary.
3. Turn on the Little Cooler before starting the distillation system.
4. *Turn off the Little Cooler approximately 1 hour after shutting down the distillation system.
This one-hour delay is necessary to condense solvent vapors remaining in the LS unit.
* Not required if connected for automatic operation.
