Safety Warnings
Regardless of the cooling system used, when in a
system, the MCU can be irreparably damaged and
may become unstable if the coolant liquid pressure
reaches or exceeds a pressure of 30 PSI (static
pressure measured at the entrance of the MCU
–
upstream of the MCU in the circuit).
Ensure that the pump is adjusted accordingly.
The cooling agent contains ethylene glycol that is a
highly flammable product. Ethylene glycol can burn
with an invisible flame that can cause serious burns
and/or other injuries.
Always handle the cooling agent carefully wearing
appropriate safety clothing and eye-glasses.
The cooling agent can irritate the skin, the eyes and
the mucous membranes.
•
Always work in a well-ventilated area when
handling the cooling agent; breathing in high
concentrations of ethylene glycol can cause
nausea.
•
In case of contact with eyes and skin, rinse
with water and consult a doctor.
•
In case of ingestion, seek medical help
immediately.
The cooling agent is under pressure when heated;
removing the cap when the coolant is hot can cause
serious burns and/or other injuries.
Wait until the coolant reaches an ambient
temperature before removing the cap.
All potential dangers of handling cooling agents
cannot be listed here.
Consult
manufacturer warnings and
recommendations for safe handling of the cooling
agent.
It is important to ensure that no voltage is present on
the high-voltage battery wires between both
polarities and from each polarity to chassis before
manipulation.
The vehicle integrator is responsible for ensuring that
proper training is given to all those who use this
system to avoid physical, electrical and operational
hazards.
