Coolant
Distilled water is the primary coolant for the unit. Ethylene glycol can be
added to prevent bacterial growth and freezing; 10% to 35% ethylene glycol is
recommended. Using at least 10% will prevent bacterial growth and at least
35% will prevent freezing to –20°C.
 Note: When using both ethylene glycol and distilled water, add the
water first, then the ethylene glycol, to ensure proper mixing.
Figure 3 on page 5 shows the coolant’s freezing point for a given percentage of
ethylene glycol in the mix. The following example shows the weights to make a
65% distilled water to 35% ethylene glycol mixture in 5 and 55 gallon quantities.
Adding Coolant
1. Make sure that the drain plug is in place.
2. Remove the filler cap on the top and at the rear of the unit.
3. Add about 3 quarts (2.9 L) of coolant.
4. Turn the unit on for a few seconds to draw coolant into the system.
5. Repeat steps 3 and 4 twice more, until the coolant remains steady at or
just below the high mark on the level gauge.
6. Replace the filler cap.
7. Turn the unit on
8. Run the unit for five minutes to remove any air trapped in the system.
WARNING
Ethylene glycol is toxic. Do not take internally.
Avoid contact with eyes, skin, and clothing. Avoid breathing vapor. Wash
thoroughly after handling.
CAUTION
Use only distilled water or a distilled water/ethylene glycol mixture (with a
maximum of 35% ethylene glycol) as coolant. Do not use tap water,
automotive antifreeze, sealants, or leak stopping material. Use of these
materials will damage the instrument and void all warranties.
