Safety Precautions
18
• Avoid wearing clothing that generates static
electricity (wool, nylon, polyester, etc.).
• Wear a wrist strap (P/N 204-622 or its
equivalent) with the lead end connected to the
microprocessor’s ground terminal. These
straps are available from most electronic
equipment distributors. DO NOT wear these
straps with power applied to the unit.
• Avoid unnecessary contact with the electronic
components.
• Store and ship electronic components in
antistatic bags and protective packaging.
• Leave electronic components in their antistatic
packing materials until you’re ready to use
them.
• After servicing any electronic components,
check the wiring for possible errors before
restoring power to the unit.
• Never use a battery and a light bulb to test
circuits on any microprocessor-based
equipment.
NOTE: The following T.I.P. Procedures may be
found in the ThermoGuard SPECTRUM TS
Multi-Temp Microprocessor Control System
Diagnostic Manual
• Calibrating the sensors.
• Replacing the microprocessor.
• Welding on the unit or truck.
Welding Precautions
Take precautions before electrically welding any
portion of the unit or the vehicle to which it is
attached. Ensure that welding currents are not
allowed to flow through the unit’s electronic
circuits.
Observe the following precautions when welding
to avoid damaging electronic components.
• If the microprocessor has a power switch, turn
it OFF before connecting or disconnecting the
battery.
• Disconnect power to the unit.
• Disconnect all wire harnesses from the
microprocessor.
• If there are any electrical circuit breakers in
the control box, switch them OFF.
• Close the control box.
• Components that could be damaged by
welding sparks should be removed from the
unit.
• Use normal welding procedures, but keep the
ground return electrode as close to the area
being welded as practical. This will reduce the
likelihood of stray welding currents passing
through any electronic circuits.
First Aid
First Aid, Refrigerant
In the event of frostbite, protect the frozen area
from further injury, warm the area rapidly and
maintain respiration.
EYES :
For contact with liquid, immediately flush
eyes with large amounts of water. CALL A
PHYSICIAN.
SKIN:
Flush area with large amounts of warm
water. Do not apply heat. Remove contaminated
clothing and shoes. Wrap burns with dry, sterile,
bulky dressing to protect from infection. CALL A
PHYSICIAN. Wash contaminated clothing before
reuse.
INHALATION:
Move victim to fresh air and use
CPR (cardio pulmonary resuscitation) or
mouth-to-mouth resuscitation to restore breathing,
if necessary. Stay with victim until emergency
personnel arrive.
First Aid, Refrigerant Oil
EYES :
Immediately flush with water for at least
15 minutes. CALL A PHYSICIAN. Wash skin
with soap and water.
INGESTION:
Do not induce vomiting.
Immediately contact local poison control center or
physician.
First Aid, Engine Coolant
EYES :
Immediately flush with water for at least
