Equipment Required (continued)
Qwik-SF® Line Set Tool
P/N QT1110
1. An empty waste container to catch waste as it exits the HVAC system.
Dispose of waste as you would dispose of used refrigerant oil.
2. Compressed nitrogen.
3. Safety glasses and protective gloves.
Application:
Qwik System Flush® is used in the same manner
as R-11 except that Qwik-SF® requires the use
of an access valve (shown in photo 1, “Access
Valve”). If you have used another brand of access
valve (i.e. , NuCalgon’s 4300-99) in the past,
then your access valve injection tool should be
compatible with Qwik-SF®. If you do not own an
injection tool, Mainstream Engineering’s Qwik-
SF® injection tool, part no. QT1105, should be
available at the location where you purchased
Qwik-SF®.
Qwik System Flush® is most commonly used to clean residual contamination after a compressor
burnout or any time you install new system components with a previously used line set. The following
instructions describe using Qwik-SF® in a proper compressor burnout/changeout procedure but are
also applicable to any other Qwik-SF® use, such as conversion of HCFC refrigeration components to
HFC refrigeration components.
When a compressor burns out, highly acidic oil is formed. Although the majority of this oil remains in
the compressor, some oil is always present in the plumbing and remaining components of the system.
If you are changing the entire system, including any piping between components in a split system,
then there are no issues. However, if you are not replacing the piping between the components or
other parts of the system, then perform the following steps:
