Pre-Work Checks

Pre-Work Checks

Prior to work on an R600a refrigerator, ensure the 

immediate area is suitable for working safely, and 

the appropriate precautions are in place.  Proper 

safety checks before beginning work will minimize 

the potential for an ignition event. Take the following 

precautions before working on the sealed system:

Ensure the area work environment is safe.

The work area should be sufficiently sized.

R600a refrigerators should not be serviced in small

poorly ventilated spaces such as very small ‘galley’

kitchens, storage closets.

Su

g

gested that you not perform sealed system

maintenance in spaces smaller than 6’ X 6’.

Refrigerators in insufficiently sized spaces should be

moved to a larger area to work safely.

The work area should be properly ventilated. Proper

ventilation allows any refrigerant inadvertently

released to disperse safely.

When working behind the appliance, create as

 

much

clearance as possible between the appliance

 

and

the wall, or other obstructions, to allow proper

 

air

movement. Locate the leak detector also behind

 

the

appliance.

Use supplemental ventilation, such as a fan.  Ensure

the fan is located at minimum of 9 feet/3 meters

from the nearest sealed system component.

Ensure a dry-powder fire extinguisher rated for

Class B fires is accessible on site.

Use of a suitable gas detector will alert the

technician of the presence of flammable gas.

If flammable refrigerant is detected, immediately

ventilate the room, evacuate the area, and notify

the owner or customer.

Recheck with a combustible gas leak detector

before proceeding.

If questioned, inform the customer the detector

allows the work to be done safely.

Remove any ignition sources from the work area

Disconnect power by unplugging the appliance

before servicing.

The area should be free of open flame or burning

materials, including cigarettes, candles, or similar

materials.

Do not operate appliances that utilize open flames

or have hot surfaces electric or gas ranges, electric

or gas dryers, toasters, electric or battery powered

tools, and other small appliances while servicing the

appliance.

Inform the homeowner/consumer that no open

ignition sources should be present in or near the area,

including cigarette smoking materials.

Check the area and the appliance for any signs of

ignition that might have occurred prior to the service.

If there are signs of ignition, stop work and ventalate

the work area.  Maintain a safe zone around the

appliance during service work to prevent ignition

sources or entry by the customers.

An appliance on/off switch, or power button, is not

adequate for removing power, as voltage will still be

present in the unit.

Ensure all necessary supplies, tools, and parts are on-

hand.

Maintain all equipment in accordance with

manufacturer specifications.

Inspect all equipment and hoses for damage prior to

each use.  Do not use damaged equipment or hoses.

Sealed System Access

 

¾

DO NOT access the sealed system by means of cutting

or breaking the sealed system piping.

 

¾

DO NOT access the sealed system by means of a torch

or any type of open flame.

 

¾

The sealed system should only be accessed through

the process tube and through the drier.

 

¾

Quick disconnect fittings must be used when accessing

the sealed system.  Use of quick disconnect valves

minimize or eliminate the discharge of any flammable 

refrigerant into the work area.  Quick disconnect 

fittings can be used with Schrader valves, if present, or 

with piercing pliers.

 

¾

If there is no direct means of accessing the sealed

system, use piercing pliers.

 

¾

If the sealed system is accessed by piercing, ensure the

correct diameter fitting is selected based on the size of

the sealed system pipe.
