by JORIX NAKAHARA

WHAT DOES RA 6969 STATE?

Regulates or prohibits the importation of chemical substances only

Control Toxic Substances and Hazardous and Nuclear Wastes Act

Regulates or prohibits the importation, manufacture, processing, sale, distribution, use and disposal of chemical substances and mixtures that harms the environment.

HOW WOULD YOU AVOID COMPRESSOR BREAKDOWN DUE TO LIQUID SLUGGING?

Invert the refrigerant tank during low pressure side charging.

Charge only from the high pressure side.

Use manifold gauge in charging refrigerant.

WHAT LUBRICANTS ARE SUITABLE FOR THE HFC REFRIGERANT?

Polyalkylene glycol (PAG) - not used for refrigeration oil purposes

Mineral oil used in all refrigeration systems

Polyolester (POE) - compatible with R-134a and R-410A

WHAT ARE THE SAFETY PRECAUTION YOU MUST TAKE WHEN PULLING-OUT AC UNIT?

Ignore ladder safety when unit is low

Use PPE

Skip PPE to save time

WHAT WOULD YOU NEED AS A GUIDE IN SERVICING AND REPAIRING THE UNIT?

Online forum opinions

Warranty sheet only

MANUAL – Because it serve as a good reference from the manufacturer.

HOW DO YOU AVOID OVERHEATING OF ELECTRICAL WIRING OF THE EQUIPMENTS?

Use undersized wires to save cost

Use octopus wiring to distribute power

Check electrical connection before plugging-in.

WHY IT IS IMPORTANT TO RECORD A REPORT AFTER REPAIRING THE UNIT?

It is optional and seldom used.

Only needed for warranty claims

It serves as a future reference in troubleshooting and repairing.

WHAT ARE THE SPECIFIED PROCEDURES IN SERVICING STUCK-UP HERMETIC MOTOR?

Disconnect the motor and wait 10 minutes

Use a larger capacitor without checking specifications

Plug-in to higher voltage source for 3-5 second.

WHAT WOULD YOU DO IF THE CONDENSER FAN MOTOR SMOKES OUT?

Continue operation to test if it clears

Turn OFF and unplug the unit, check motor lubrication and its windings.

Pour water on motor to cool it

WHAT WOULD YOU DO IF THE EVAPORATOR OF THE REFRIGERATOR IS NOT FREEZING?

Ignore leaks and keep charging

Check leaks through joints/brazed part using soap bubbles or an electronic detector.

Replace the whole system immediately

HOW DO REFRIGERANT CREATE ITS REFRIGERATING EFFECT?

By chemical reaction with ambient air

By heating the surroundings

Through refrigeration cycle.

HOW WOULD YOU EVALUATE WHETHER THE UNIT IS 100% EFFICIENT?

Check the amperage and compare to manufacturer’s sticker amperage rating.

Estimate by feel of the airflow

Count the number of components in the system

WHY WE NEED TO WEAR PPE?

To ensure safety

To comply with a dress code

To look professional

HOW DO YOU TEST IF THE CAPACITOR IS DEFECTIVE?

Bend the capacitor leads and observe physical flex

Dip in water to test insulation

Set the multi-tester to ohmmeter (RX1K), place test probes to each capacitor terminals and there should be a deflection shown in the tester.

WHAT WOULD YOU DO IF THE EVAPORATOR OF THE AC UNIT IS PARTIALLY COOLING?

Check the condenser and evaporator if dirty, then clean it; Check refrigerant charge, add if insufficient.

Only check the condenser, not the evaporator

Ignore and run longer cycles

WHAT WOULD YOU DO IF THE REFRIGERATOR BODY IS GROUNDED?

Inspect all wirings and insulations, locate the open wires and seal it with electrical tape.

Disconnect all power sources only

Replace the entire wiring harness without inspection

WHAT IS THE IMPORTANCE OF LABELING THE TANK AFTER RECOVERY AND RECYCLING OF REFRIGERANT?

For easy identification

To allow faster charging later

To comply with branding

WHAT WOULD YOU DO IF YOU CHARGE THE UNIT WITH WRONG REFRIGERANT?

Continue charging and hope for best

Mix the refrigerants together to balance pressures

Recover and evacuate the system, then flush the system with nitrogen or its refrigerant and charge again.

WHAT WOULD YOU DO TO OPTIMIZE RECOVERY OF REFRIGERANT?

Recover small amounts only

Use a good recovery machine.

Use any available pump

WHAT LAW/ISSUENCE REGULATES THE VENTING OF REFRIGERANT?

Clean Air Act

Food and Drug Act

Environmental Sustainability Act

WHAT TWO ORGANIZATIONS ADDRESS THE ENVIRONMENTAL ISSUES ON CFC PHASE OUT PLAN?

Greenpeace; World Health Organization

The Montreal Protocol; United Nations Development Programme

World Trade Organization; International Monetary Fund

HOW WOULD YOU DISPOSE OLD REFRIGERANT OIL?

Pour it down the drain

Bury it in the yard

Place it in a tank and store in a safe place with label

WHAT WOULD YOU DO AFTER SERVICING AND STARTING-UP IF YOU HEARED A NOISE?

Ignore the noise until it worsens

Turn up the volume to drown the noise

Locate the noise, then unplug the unit, fix/repair the parts that causes the noise.
