Hazards
As some coolant ages, dangerous microbes can
proliferate and create a biological hazard. The risk
of exposure to this hazard can be greatly reduced
by replacing the old coolant on a regular basis, as
indicated in the maintenance schedule.
The important thing to keep in mind when working
with the coolant is to minimize exposure to your
skin, eyes, and respiratory system by wearing
the proper PPE (personal protective equipment),
such as splash-resistant safety glasses, long-
sleeve gloves, protective clothing, and a NIOSH-
approved respirator.
BIOLOGICAL & POISON
Use the correct person-
al protection equipment
when handling coolant.
Follow federal, state,
and fluid manufacturer
requirements for proper
disposal.
A small amount of coolant is lost during normal
operation. Check the coolant reservoir regularly
and fill it if necessary. We recommend chang-
ing the coolant every three months or sooner if it
develops an unpleasant odor. However, be sure
to follow the coolant manufacturer's instructions
when checking, adding, or changing coolant.
Coolant Reservoir Capacity ..... 4.75 Gal. (18L)
Running coolant pump without adequate
coolant in reservoir may permanently
damage coolant pump, which will not be
covered by warranty.
