Safety Precautions
14
Refrigeration Oil
Observe the following precautions when working
with or around synthetic or polyol ester refrigerant
oil:
•
Do not allow refrigerant oil to contact your
eyes.
•
Do not allow prolonged or repeated contact
with skin or clothing.
•
To prevent irritation, you should wash
thoroughly immediately after handling
refrigerant oil. Rubber gloves are
recommended when handling polyol ester oil.
First Aid
•
Eyes: Immediately flush eyes with large
amounts of water for at least 15 minutes while
holding the eyelids open. Get prompt medical
attention.
•
Skin: Remove contaminated clothing. Wash
thoroughly with soap and water. Get medical
attention if irritation persists.
•
Inhalation: Move victim to fresh air and
restore breathing if necessary. Stay with
victim until arrival of emergency personnel.
•
Ingestion: Do not induce vomiting. Contact a
local poison control center or physician
immediately.
Electrical Hazards
Microprocessor Service
Precautions must be taken to prevent electrostatic
discharge when servicing the microprocessor
controller and related components. Potential
differences considerably lower than those which
produce a small spark from a finger to a door
knob can severely damage or destroy solid-state
integrated circuit components.
The following procedures must be rigidly adhered
to when servicing units to avoid microprocessor
damage or destruction.
1. Disconnect all power to the unit.
2. Avoid wearing clothing that generates static
electricity (wool, nylon, polyester, etc.).
3. Do wear a static discharge wrist strap (see
Tool Catalog) with the lead end connected to
the microprocessor’s ground terminal. These
straps are available at most electronic
equipment distributors. Do not wear these
straps with power applied to the unit.
See the ThermoGuard
µ
P-IV Microprocessor
Controller Operations and Diagnosis Manual
(T.I.P. Procedure #P41AA12B) and the
Electrostatic Discharge Training Guide for
additional information.
4. Avoid contacting the electronic components
on the circuit boards of the unit being
serviced.
5. Leave the circuit boards in their static proof
packing materials until ready for installation.
6. If a defective controller is to be returned for
repair, it should be returned in the same static
protective packing materials from which the
replacement component was removed.
7. After servicing the controller or any other
circuits, the wiring should be checked for
possible errors before restoring power.
8. Never use testers consisting of a battery and a
light bulb to test circuits on any
microprocessor based equipment.
9. Before connecting or disconnecting the
battery, the Microprocessor On/Off switch
must be turned to the Off position.
NOTE: The following T.I.P. Procedures may be
found in the ThermoGuard
µ
P-IV
Microprocessor Controller Operations and
Diagnosis Manual.
•
Replacing and calibrating the return air and
discharge sensor.
•
Replacing the
µ
P-T microprocessor.
•
Welding on the unit or truck.
