Safety Instructions

General Precautions

• Always wear goggles or safety glasses.

Refrigerant liquid and battery acid can

permanently damage the eyes.

• Never operate the unit with the discharge

valve closed. Never close the compressor

discharge valve with the unit in operation.

• Keep your hands, clothing and tools clear of

the fans when the refrigeration unit is running.

If it is necessary to run th e ref rigeration unit

with covers removed, be very careful with

tools or meters being used in the area.

• Check the condition of the gauge manifold

hoses. Never let the hoses come in contact

with a fan motor blade or any hot surface.

• Never apply heat to a sealed refr igeration

system or container.

• Fluorocarbon refrigerants produce toxic gases

in the presence of an open flame or electrical

arc. The gases are severe respiratory irrit ants

capable of causing death.

• Firmly tighten all mounting bolts. Check each

bolt for correct length for their particular

application.

• Use extreme caution when drilling holes in the

unit. The holes may weaken structural

components. Holes drilled into electrical

wiring can cause fire or ex plosion. Holes

drilled into the refrigeration system may

release refrigerant.

• Use caution when working around expos e d

coil fins. The fins can cause painful

lacerations.

• Use caution when working with a refrigerant

or refrigeration system in any closed or

confined area with a limited air supply (for

example, a trailer, container or in the hold of a

ship). Refrigerant tends to displace air and can

cause oxygen depletion. This can result in

suffocation and possible death.

• Use caution and follow t he manufacturer’s

suggested pract i c es wh en us in g la d de rs or

scaffolds

Refrigerant Oil Precautions

Observe the following precautions when work ing with or around refrigerant oil:

• Do not allow refrigerant oil to contact your eyes.

• Rubber gloves are recommen ded when handling Poly ol Ester based refrigerant oil.

• Do not allow prolonged or repeated contact with skin or clothing.

• Immediately wash all exposed skin after handling refrigerant oil.

Use the following First Aid practices if needed.

Eyes: Immediately fl ush ey es wi th lar ge a mount s

of water. Continue flushing for at least 15 minutes while holding the eyelids open. Get prompt medical attention.

Skin: Remove contaminated clothing. Wash

thoroughly with s oap and water. Get medical attention if irri tation persists.

Inhalation: Move victim to fresh air. Restore

breathing if necess a ry. Stay with victim until arrival of emergency pers onnel.

Ingestion: Do not induce vomiting. Contact a

local poison control cen ter or physician immediately.

Electrical Precautions

The possibility of serious or f a tal injury from electrical shock exists when servicing a refrigeration unit. Extreme car e must be used when working with a refriger ation unit that is connected to its power source. Extreme care must be used even if the unit is not running . Let hal voltage potentials can exist at the unit power cord, inside the control box, inside any high voltage junction box, at the motors and within the wiring harnesses.

Precautions

• Turn the unit On/Off switch to Off before connecting or disconnecting the unit p ower plug. Never attempt to stop the unit by disconnectin g th e po we r pl ug .

Safety Instructions

• Be certain the unit power plug is clean and dry before connecting it to a power source.

• Use tools with insulated handles. Use tools that are in good con dition. Never hold metal tools in your hand if exposed, energized conductors are within reach.

• Do not make any rapid moves when working with high voltage circuits. Do not grab a falling tool or other object. Peop le do not contact high voltage wires on purpose. It occurs from an unplanned movement.

• Treat all wires and connections as high voltage until ammeter and wiring d iagram show otherwise.

• Never work alone on high voltage circuits on the refrigeration unit. Another person should always be standing by in the event of an accident to shut off the refrigeration unit and to aid a victim.

• Have electrically insulated gloves, cable cutters and safety glasses availab le in the immediate vicinity in the event of an accident.

First Aid

IMMEDIATE action must be initiated after a person has received an electrical shock. Obtain immediate medical assistance.

The source of shock must be immediately removed. Sh ut down the power or remove the victim from the source. If it is not possible to shut off the power, the wire should be cut with either an insulated inst rument (e.g., a wooden handled axe or cable cutters with heavy insulated handles). A rescuer wearing electrically insulated gloves and safety glasses could also cut the wire. Do not look at the wire while it is being cut. The ensuing flash can cause burns and blindn ess.

Pull the victim off with a non-conductive material if the victim has to be removed from a live circuit. Use the victim’s coat, a rope, wood, or loop your belt around the victim ’s leg or arm and pull the victim off. Do not touch the victim. You can receive a shock from current flowing thr ough the victim’s body.

Check immediately for the presence of a pulse and respiration afte r sep ara tin g the vic tim fr om p ower source. If a pulse is not present, start CPR (Cardio Pulmonary Resuscitation) and call for emergency medical assistance. Respiration may also be restored by using mou th-to-mouth resuscitation.

Low Voltage

Control circuits are low voltage (24 Vac and 12 Vdc). This voltage potent ial is not considered dangerous. Large amount of curr ent available (over 30 amperes) can cause severe burns if shorted to ground. Do not wear jewelry, watch or rings. These items can shortcut electrical circuits and cause severe burns to the wearer.

Electrostatic Discharge Precautions

Precautions must be taken to prevent electrostatic discharge while servicing the MP-3000a microprocessor an d re l ate d co mponents. The risk of significant damage to the electro nic components of the unit is possible i f th ese precautionary measures are not followed. The primary risk poten tial results from the failure to wear adequate electrostatic discharge preventive equipment when handling and servicing the controller. The second cause results from electric welding on the unit and container chassis without taking precautionary steps.

Electrostatic Discharge and the Controller

You must avoid electrostatic discharges when servicing the controller. Solid-state integrated circuit compon ents can be severely damaged or destroyed with less than a small spark from a finger to metal object. You must rigidly adhere to the following statements when servicing these units. This will avoid controller damage or destruction.

• Disconnect all power to the unit.

• Avoid wearing clothing that generates static electricity (wool, nylon, polyester, etc.).

• Do wear a static discharge wrist strap (refer to Tool Catalog) with the lead end connected to the controller's ground terminal. These straps

Safety Instructions

are available at most electronic eq uipment distributors. Do not wear these straps with power applied to the unit.

• Avoid contacting the electron ic components on the circuit boards of the unit being serviced.

• Leave the circuit boards in their static proof packing materials unti l ready for installation.

• Return a defective controller for repair in the same static protective packing materials from which the replacement component was removed.

• Check the wiring after serv icing the unit for possible errors. Complete this task before restoring power.

Welding of Units or Containers

Electric welding can cause serious damage to electronic circuits when performed on any portion of the refrigeration unit, container or container chassis with the refrigerat ion unit attached. It is necessary to ensure that welding currents are not allowed to flow through the electronic circuits of the unit. The following statements must be rigidly adhered to when servicing these units to avoid damage or destruction.

• Disconnect all power to the refrigeration unit.

• Disconnect all quick-disconnect wire harnesses from the back of the controller.

• Disconnect all wire ha rnesses from the Remote Monitor Modem (RMM).

• Switch all of the electrical circuit breakers in the control box to the Off position.

• Weld unit and/or container per normal welding procedures. Keep ground return electrode as close to the area to be welded as practical. This will reduce the likelihood of stray welding currents passing through any electrical or electronic circuits.

• The unit power cables, wiring and circuit breakers must be restored to their normal condition when t he welding operation is completed.

Removing Refrigerant Properly

Use a refrigerant recovery process that prevents or absolutely minimizes refrigerant escaping to the atmosphere. Fluorocarbon refrigeran ts are classified as safe refrigerants when pr oper tools and procedures are used. Certain precautions must be observed when handling them or servicing a unit in which they are used.

Fluorocarbon refrigerants evaporate rapidly, freezing anything they contact when exposed to the atmosphere in the liquid state. In the event of frost bite, attempt to protect the frozen area from further injury, warm the affected area rapidly , and maintain respiration.

• Eyes: For contact with liquid, immediately flush eyes with large amounts of water and get prompt medical atten ti on .

• Skin: Flush area with large amounts of lukewarm water. Do not apply heat. Remove contaminated clothing and shoes. Wrap burns with dry, sterile, bulky dressing to protect from infection/injury. Get medical attention. Wash contaminated clothing before reuse.

• Inhalation: Move victim to fresh air and use CPR or mouth-to-m ou t h ve nt ilation, if necessary. Stay with victim un til arrival of emergency medical personnel.

• Manual Switch or Demand Defrost Initiation: Coil must be below 18 C (65 F). Defrost cycle starts when technician or controller requests defrost initiation.

• Timed Defrost Initiation: Coil must be below 10 C (50 F). Defrost cycle starts 1 minute after the hour immediately following a defrost timer request for defrost initiation. For example, if the defrost timer requests a defrost cycle at 7:35, the defrost cycle will start at 8:01. Datalogger will record a Defrost event for each interval in which a Defrost cycle is pending or active (i.e. both the 8:00 and 9:00 data logs).

Demand defrost function initiates defrost when:

• Temperature difference between the return air sensor and defrost (evaporator coil) sensor is too large for 90 minutes

• Temperature difference between the left hand and right hand supply air sensors is too large and unit has operated for 90 minutes since last defrost

• Temperature difference between the supply air sensors and return air sensor is too large

• Supply Temperature at 5.1 C (41.2 F) or Above: Every 8 hours of compressor operation.

• Supply Temperature at 5.0 C (41.0 F) or Below: Every 2.5 hours of compressor operation. Defrost interval increases 0.5 hours each timed defrost interval. Defrost synchronization creates step intervals of 3, 4, 4, 5, 5, 6, 6 and 7 hours. Maximum time interval in Chilled mode is 7 hours.

Every 8 hours of compressor operation. Defrost interval increases 2 hours each timed defrost interval. Maximum time interval in Frozen mode is 24 hours.

Defrost timer resets if the unit is off more than 12 hours, setpoint is changed more than 5 C (9 F) or PTI pretrip test occurs.

Chilled mode: Terminates defrost when coil sensor temperature rises to 30 C (86 F); or exceeds 18 C (65 F) for 35 minutes/45 minutes if voltage is less than 440 volts.

Frozen mode: Terminates defrost when coil sensor temperature rises to 30 C (86 F); or exceeds 8 C (46 F) for 35 minutes/45 minutes if voltage is less than 440 volts.

Terminates defrost after 90 minutes at 60 HZ operation if coil sensor has not terminated defrost (120 minutes at 50 Hz operation)
