HGM-TS Location
The condensing unit is located at the top of
the HGM-TS. At least 12 inches of clearance
should be allowed at the rear of the cabinet and
at the top of the merchandiser. This clearance is
necessary to provide free air movement to and
from the condensing unit for maximum
operating efficiency.
At least 24 inches of clearance should be
maintained in front of HGM-BS merchandisers
and 6 inches of clearance at the rear to provide
the necessary free air movement to and from
the condensing unit. The condensing unit is
located at the bottom of these merchandiser.
HGM-2BS merchandisers require the same
clearance space, but the air flow is different
as shown in the illustration at right. Avoid
installing 1-door merchandisers on the left side
of the case.

designedtosupportexcessiveexternal
loadingsuch as the weight of a person. Do
not place heavy objects on the merchandiser.
SHIPPING SKID
Each merchandiser is shipped on a skid to
protect the merchandiser’s base, and to make
positioning the case easier.
Remove the top of the crate and detach walls
from each other. Lift crate from the skid.
Unscrew the case from the skid. The fixture
can now be lifted off the crate skid. Lift only at base of skid! Remove any braces and/or skids
attached (blanket wrapped merchandiser may
have skids).
DO NOT TILT MERCHANDISER ON ITS
SIDE OR END WHEN REMOVING SKID.
Tilting merchandiser could cause damage to
the refrigeration system.
Once the skid is removed, the merchandiser
must be lifted —NOT PUSHED— to reposition.
To remove the skid, remove screws attaching
skid to the merchandiser.
Do not store objects or ammable
materials atop the unit.
Check floor where cases are to be set to see if
it is a level area. Determine the highest part of
the floor.
Merchandiser(s) must be installed level to
ensure proper operation of the refrigeration
system and to ensure proper drainage of
defrost water. The merchandiser can be leveled
by shimming under the cabinet base frame, or
by installing optional leg levelers.
The self-closing doors require the cabinet to be
properly leveled. End to end leveling will allow
the door(s) to close with uniform speed and
tightness. A slight pitch from front to rear
is desirable.

LEG INSTALLATION (Top Mounts Only)
Install the NSF approved legs after the case is
near its final location. The legs are packaged
inside the cabinet. Replace the tape and door
blocks.
To install legs:
Raise one end of the cabinet about 8 inches.
Block the merchandiser securely, and install
two legs. The leg mounting plates are factory
installed and contain a
1
/2 x 13 in. tapped hole
to mate with the leg assembly. The procedure
is repeated on the opposite end. Three-door
merchandisers require legs in the center.
The cabinet should now be positioned at its
final location with all legs installed. The
merchandiser is leveled by turning the bottom
section of each leg . End to end leveling will
make the door(s) close with uniform speed and
tightness. A slight pitch from front to rear is
desirable.
SERIAL PLATE LOCATION
The serial plate is located in the upper lefthand corner of the merchandiser’s interior.
The serial plate contains all pertinent
information such as model, serial number,

REFRIGERATION UNIT ACCESS
Top Mounts — The top decorative panel is
removed by lifting the panel up and pulling
forward.
Bottom Mounts — The lower front panel may
be removed by removing screw at bottom and
lifting the panel straight upward and over
the tabs on which it is hanging. The panel is
installed by reversing the above procedure.
Then
Lift up and
out to remove
access panel
First
Ensure lower front panel is flat against the
floor when installed to prevent air circulation
problems for self contained merchandisers.
If the condensing unit needs to be serviced, it
can be pulled out to gain access for hard to
reach components like the condenser fans.
To pull out the condensing unit, remove the
two hold down brackets at the unit base.
Care must be given to the drain line when
replacing the condensing unit into the case.
The drain line must be inside the defrost water
evaporation pan to prevent the discharge of
water on the floor.
SEALING MERCHANDISER TO FLOOR
(Bottom Mounts Only)
If required by local sanitary codes, or if the
customer desires, merchandisers may be sealed
to the floor using a vinyl cove base trim. The
size needed will depend on how much variation
there is in the floor, from one end of the
merchandiser to the other. Sealing of the lower
front and rear panels on self contained models
may hamper their removal for servicing or
maintenance of the condensing unit.
NOTE: Do not allow trim to cover any intake
or discharge grilles located in the lower front
panel.
AIR DISTRIBUTION & REAR FLUE
SPACER
Air is drawn through the evaporator from
front to rear and is discharged down the back
wall, returning up the face of the glass door to
the return air grille.
NOTE: Rear flue spacer must be in place as
this forms a discharge air flue at the back of
the cabinet.
SHELVES
Each cabinet is provided with four cantilever
shelves per door that are adjustable by 1 inch
increments. The shelves can also be tilted.
Each cabinet has one bottom shelf per door.
These shelves have one-inch legs to allow
proper air flow in the cabinet. Behind the
shelves are wire flues spacers, which allow for
proper air flow. All shelves and flue spacers
are white and epoxy coated for durability and
ease of cleaning. Shelves should be adjusted to
desired operating height. Do not load product
so that it touches the evaporator coil cover.
Do not extend product past the front edge of
the shelf. Extending past the edge will seriously
affect internal air flow through the cabinet.
Shelves are UL rated for a maximum load of
120 lbs.

If an attempt to clear the restriction by this
method are unsuccessful, the entire assembly,
not the capillary tube only, should be replaced
with a new factory ordered replacement.
Refrigerant flow to the evaporator is controlled through the use of a capillary tube.
Because the suction line capillary tube assembly, sometimes referred to as heat exchanger or
pull-out coil has no moving parts, it will rarely
need servicing. However, if a leak occurs in
the refrigeration system, it is possibly that dirt,
dust, or moisture may collect in the capillary
tube causing the system to go into a vacuum.
Should this occur, it is recommended that dry
nitrogen or a dry refrigerant be forced through
the system to clear blockage.

4-2 Maintenance
CLEANING STAINLESS STEEL SURFACES
Use non-abrasive cleaning materials, and
always polish with grain of the steel. Use warm
water or add a mild detergent to the water and
apply with a cloth. Always wipe rails dry after
wetting.
Use alkaline chlorinated or non-chlorine
containing cleaners such as window cleaners
and mild detergents. Do not use cleaners
containing salts as this may cause pitting and
rusting of the stainless steel finish. Do not
use bleach.
SHUT FANS OFF DURING
CLEANING PROCESS.
CLEANING COILS
The condenser can be inspected without
pulling the whole condensing unit out of the
case. Simply remove the grille on the intake
side of the condensing unit for HGM-BS
merchandisers. For HGM-TS, the condensing
unit is located at the top of the merchandiser.
Condenser coils should be cleaned at least once
per month. Additional cleaning may be needed
depending on the operational environment. A
dirty condenser blocks normal airflow through
the coils.
Airflow blockage increases energy consumption
and reduces the merchandiser’s ability to
maintain operating temperature.
To clean the coils, use a vacuum cleaner with
a wand attachment and a soft (non-metallic)
brush to remove dirt and debris. Do not bend
coil fins. Always wear gloves and protective
eye wear when cleaning near sharp coil fins
and dust particles.
— LOCK OUT / TAG OUT —
To avoid serious injury or death from electrical
shock, always disconnect the electrical power
at the main disconnect when servicing or
replacing any electrical component. This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.
The condensate water outlet empties into a
limited capacity evaporation pan.

evaporation pan heater, and allow pan to cool.
reduce the pan’s evaporation capacity and
cause premature heater failure. The evaporation
pan waste water will overflow and spill onto the
floor if the heater is not properly operating.
Always wear protective eye glasses and gloves
when servicing.
Remove accumulated debris from the
evaporation pan. Wipe down heater coil with a
cloth and warm water. Be sure to remove any
dirt, debris or liquids from the heater coil.
Water introduced during cleaning will cause
the evaporation pan to overflow.
Use only enough water necessary to clean
surface. Water must not drip down the case!
Never use ammonia based cleansers, abrasive
DO NOT FLOOD!
cleansers, or scouring pads.
When Cleaning:
Do not use high pressure water hoses
Do not introduce water faster than waste outlet can drain
NEVER INTRODUCE WATER ON SELF CONTAINED
UNIT WITH AN EVAPORATION PAN
NEVER USE A CLEANING OR SANITIZING SOLUTION
THAT HAS OIL BASE (these will dissolve the butyl
sealants) or and AMMONIA BASE (this will corrode the
copper components of the merchandiser)
TO PRESERVE THE ATTRACTIVE FINISH:
Use a water and a mild detergent for the exterior only
Do NOT use a chlorinated cleaner on any surface
Do NOT use abrasives or steel wool scouring pads
(these will mar the finish)
