and/or operational.
WARNING
!
Cabinet Shell
Cabinet shell is made of steel, with all seams welded and
all points of stress adequately braced.
Refrigeration system condenser tubes are attached to
the inner surfaces of the cabinet shell by means of spot
welded clamps. Forming a shell-type condenser which
provides quiet operation and efficient heat dissipation.
This method of dissipating the condenser heat eliminates
the formation of condensation on exterior surfaces of the
cabinet.
Steel base rails provide a platform on which the cabinet
shell is mounted. Two adjustable levelling glides are
inserted into the base rails, one at each front corner.
Door lock retainer and strike are also attached to the
cabinet shell (if equipped).
Cabinet Liner (Food)
Cabinet liner is made of a tough, flexible, plastic or high
impact polystyrene material and is secured to the cabinet
shell with retaining clips.
Following components are attached to the cabinet liner
by utilising special snap nuts, clips and other fasteners;
interior light and switch, cold control assembly and cover,
evaporator coil and cover (no frost models), shelves and
gate mounting hardware, and drain tube and grommet.
Once system components and cabinet liner have been
assembled to the cabinet shell, polyurethane insulation is
foamed in to fill the void between the shell and liner.
NOTE:
Cabinet (food) liner cannot be removed on the
current models with foam insulation.
Drain System
Freezer drain system consists of a drain grommet and
sleeve at the liner and cabinet bottom, and a drain hose
and tube that carries the defrost water.
NOTE:
Refrigerated shelf models are equipped with a
drain cap that must be removed before
defrosting and replaced securely afterwards.
On refrigerated shelf models, defrost water is carried
through the front face plate of the cabinet where it can be
collected into a container for disposal
Drain System Refrigerated Shelf Models
On no-defrost models, drain grommet and sleeve are
located in the center of drain trough which has been
formed in the cabinet liner. During defrost cycle, water is
carried through the drain hose and tube into the moisture
pan which is located under the cabinet. Heat from the
precooler condenser hastens the evaporation process.
Drain System No-Defrost Models
Drain tube grommets should never need replacing
unless it has deteriorated.
If drain system becomes clogged, push a length of
plastic cloths line completely through and flush with
warm water.
