c)
Clean the surface of the door with
isopropyl alcohol and either air dry or dry
with a clean cloth.
d)
Heating the surface of the door
immediately before applying the decal will
aid the adhesive bond of the decal. Never
apply a decal to a surface that is colder
than 50° F.
e)
Use a soft roller or plastic squeegee to
apply the decal and press it into the
embossed surface of the metal. Applying a
small amount of heat to the surface of the
decal will aid in this process.
Door Gaskets and Hardware
:
Routine
inspection of the door gasket seal and the action
of the door’s hinges are recommended. If damage
has occurred to the gasket, it may allow outside
air to penetrate the cabinet and the gasket should
be replaced. The upright solid door utilizes the
same hinge as the glass door. Leer solid doors
have a barbed dart that inserts into a slot opening
in the surface of the door frame. See
Figure 3
for
instructions on solid door gasket replacement.
R290 Refrigeration Service:
Danger: Do not attempt to open the
refrigeration system! Propane is a flammable
and explosive gas.
Like other refrigeration systems, a unit charged
with R290 is not serviceable on a consumer level.
Experienced technicians can contact Leer for an
in-depth service and guideline manual. The use of
special tools and proper procedures performed by
licensed, trained and qualified professionals is
required.
R290 General Information
:
R290 refrigerant is flammable, but the amount of
refrigerant used is relatively small and the chance
of ignition in the event of refrigerant leak is
extremely low. Millions of commercial and
residential refrigeration products are already using
similar, if not exact, refrigerants worldwide.
R290 refrigeration grade propane has a much
higher purity than standard propane. The higher
moisture content of standard propane will damage
a refrigeration system. Standard propane also has
a scent added (another impurity) that refrigeration
grade materials do not.
R290 is a high-performance refrigerant. The
superior thermodynamic properties of R290
compared to R404a and R134a allow for a
reduced charge per system and lower system
energy use.
Most important, It’s eco-friendly! R290 is
classified as a hydrocarbon (HC) refrigerant,
which is a natural, non-toxic, refrigerant and the
top alternative to hydrofluorocarbon (HFC)
refrigerants. R290 has an Ozone Depletion
Potential (ODP) of 0 and an ultra-low Global
Warming Potential (GWP) of 3.
