INTRODUCTION, INSPECTION UPON RECEIPT , PROPER LOCATION
CLEARANCE, AND INITIAL SET-UP
Introduction –
Hussmann HGL-TS/BS models are
self-contained, low temperature, vertical dis-
play merchandisers for ice cream and frozen
foods. Design features include heated glass
doors for fog free visibility, automatic defrost,
efficient foamed in place non-CFC insulation,
cord connection for 208-230 volt application
and balanced refrigeration systems for energy
saving performance.
Inspection upon receipt –
Upon receipt of the cabinet, carefully
examine the crating for damage. If crate is
damaged, make a note on the delivery ticket
before signing. Carefully remove shipping
crate and examine cabinet for “concealed”
damage. If damage is found, contact the de-
livery carrier immediately and have his agent
prepare an inspection report for the purpose
of filing a claim. THIS IS YOUR RESPONSI-
BILITY.
Proper Location & Clearance –
Avoid locating the cabinet where direct
sunlight would shine into the fixture or where
drafts from air conditioning grills, fans and
open doors could affect its operation.
Because the condensing unit is located
at the top of the HGL-TS, at least twelve (12)
inches of clearance should be allowed at the
rear of the cabinet and at the top of the case.
This clearance is necessary to provide free air
movement to and from the condenser for
maximum operating efficiency.
Because the condensing unit is located on the
bottom of the HGL-BS, at least twenty four (24)
inches of clearance should be allowed in front of
the case and six (6) inches of clearance at the
rear to provide the necessary free air movement
to and from the condenser for maximum operat-
ing efficiency.
Initial Set-Up
Skid –
The skid should be left on the case until it
is near its final location. The skid provides pro-
tection for both case and floor. The skid is re-
moved by raising one end of the case approxi-
mately six inches. Block securely and remove
the two skid bolts on the raised end. The proce-
dure is repeated on the opposite end. When the
skid bolts are removed, the case may be slid off
the skid.
Leg Installation – Top Mounts Only
After the case is near its final location
and the skid has been removed, the NSF ap-
proved legs should be installed. The legs are
packaged inside the cabinet. Replace the tape
and door blocks. To install legs, raise one end of
the cabinet approximately eight (8) inches, block
securely, and install two legs. The leg mounting
plates are factory installed and contain a ½ x 13
tapped hole to mate with the leg assembly. The
procedure is repeated on the opposite end. The
3-door requires legs in the center. With cabinet
legs installed, the cabinet should be positioned in
its final location and leveled.
The cabinet is leveled by turning the bot-
tom section of each leg. The self-closing doors
require the cabinet to be properly

Page 4
leveled. End to end leveling will make the door (s)
close with uniform speed and tightness. A slight
pitch from front to rear is desirable. THE CABI-
NET BACK SHOULD NEVER BE HIGHER
THAN THE FRONT.
Leveling & Sealing – Bottom Mounts Only
The case can be leveled by shimming under
the cabinet base frame, or by installing optional
levelers. The self-closing doors require the cabinet
to be properly leveled. End to end leveling will
make the doors close
with uniform speed and tightness. A slight pitch
from front to rear is desirable. Once level the case
should be sealed to the floor as shown in the fol-
lowing drawing, using an NSF approved material
such as General Electric RTV-102 silicone sealer
or an equivalent.
Conensate Pan –
An electrically heated (300W, 208-230v)
condensate pan is provided to evaporate the de-
frost water. The heated condensate pan slides
onto the slide plate on the cabinet bottom on both
the TS and BS cases. The pan is removable for
cleaning. A vinyl drain tube is provided for con-
nection to the heated condensate pan. The drain
must be trapped to guard against drain line freez-
ing and for good sanitation practice.
Bottom Louvered Panel Removal –
The louvered panel provides access to the
condensing unit and the electrical box. Remove
panel by removing shipping screw (s) at
bottom and lifting up and pulling forward. Re-
move shipping screw on electrical box to allow the
electrical box to slide out for servicing.
Top Decorative Panel Removal –
The top decorative panel is removed by lift-
ing up and pulling forward.
Compressor –
The compressor is mounted on springs and
banded for shipping purposes and this band needs
to be cut upon installation. Do not loosen the com-
pressor mounting bolts, as these are factory pre-set
for proper riding on the springs.
Shelves –
Each cabinet is provided with 4-cantilever
shelves per door that are adjustable on 1-inch in-
crements and are tiltable. Each cabinet also has
one bottom shelf per door. These shelves have one
inch legs to allow proper airflow in the cabinet.
Behind the shelves are wire flue spacers which also
allow for proper airflow. All shelves and flue spac-
ers are white, epoxy coated for durability and ease
of cleaning. Shelves should be adjusted to desired
operating height.
When loading product into the cabinet, care
should be taken not to load product so that it
touches the evaporator coil cover, also, do not ex-
tend product past the front edge of the shelf. Ex-
tending past the edge will seriously effect internal
air flow through out the cabinet.
Shelves are UL rated for a maximum load of
123 lbs. DO NOT OVERLOAD SHELVES.

During the defrost cycle, the cover gets warm
and some product softening may occur if prod-
uct is touching the cover.
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 grill.
Electrical Connections, Volts, Amperage and Ship Wt.
The HGL cases are supplied with a supply cord as charted below with a grounding
prong for operation on 208-230 power supplies. Do not remove the grounding prong under
any circumstances.
NOTE: Connecting this unit to any electrical supply other than
specified on the serial plate will void the warranty and may result
in serious damage to the unit. The cabinet should be supplied with
its own service.

The HGL cases use R-404A refrigerant. Check the serial plate for the specific refrigerant charge
used. The serial plate is located in the upper left-hand corner of the case interior. It has all the
pertinent information needed for proper electrical installation. The serial plate should not be re-
moved for any reason.
INITIAL START-UP AND LOADINGGENERAL UPKEEP AND CLEANING
OPERATION AND MAINTENANCE
Start-Up and Loading –
 After the wiring has been completed, set the
defrost timer for the correct time of day,
making sure the defrost pins are secure in
the face of the clock. HGL cabinets are fac-
tory set for 2 defrost periods in 24 hours (6
a.m. and 10 p.m.)
 Cut the band holding the compressor in
place during shipping.
 Check the cabinet thoroughly for loose nuts
and bolts and electrical connections. Inspect
the refrigerant lines for any visible damage
or chafing.
 Replace the electrical box cover.
 Start the cabinet and allow to pull down to
operating temperature before loading.
General Upkeep & Cleaning –
To insure good sanitation, appearance, and
minimum maintenance, the cabinet should be
cleaned and washed regularly as use demands.
Clean with mild detergent and warm water.
. Do not use an abrasive cleaner or steel
wool, as they will mar the finish.
Under normal conditions, after the
cabinet is installed and running, very little
maintenance should be required. However,
the following list of housekeeping practices
will assure trouble-free operation.
♦ Check operation of condenser fan motors.
Fan blades must turn freely.
♦ Check drain pan and heater to prevent
accidental overflow.
♦ Make sure doors are closing properly and
that the gaskets seal.
♦ Make sure all evaporator fan motors are
running. These can be seen through grill
inside cabinet.
♦ Clean the cabinet with a mild detergent.
This will insure good sanitation, and
minimize maintenance. Never use an
abrasive as this could mar the finish.

Page 7
♦ A regular program should be set up for the
cleaning of the fin-and-tube condenser.
Normally, this cleaning is required every 3
to 4 months, but the individual store appli-
cation may shorten or lengthen this time pe-
riod. Dust and dirt accumulation can cause
serious efficiency loss. On BS cases (bottom
mounts) access is gained to the unit area by
removing the louvered grille. The unit
slides forward to facilitate cleaning and for
service. Care should be taken when pushing
the unit back in place to insure that the pull-
out coil does not become kinked or damaged
in some way.
Power Switches –
The power switch is located at the elec-
trical box, which is behind the top decorative
panel (TS models) or bottom louvered panel
(BS models). The switch will shut off all
power to the case.
Before any service is performed on this
piece of equipment, make sure the power sup-
ply to the cabinet is disconnected.
Temperature Control –
The electronic temperature control is
located in the electrical box. The temperature
control does not have an 'OFF' position. Ad-
justments may be made by turning the knob on
the face of the dial. Turning it counter clock-
wise will give colder temperatures. There is
also an adjustable temperature differential (the
difference between the cut-in temperature and
the cut-out temperature) located on the back of
the temperature control cover. When adjusting
the differential, the temperature setting may
also have to be adjusted.
The control has a range of –20° F to +100°F
with a differential of 1° to 30°. It is factory
set for approximately – 18° F with a 8° dif-
ferential. The temperature should be
checked with a thermometer other than the
case thermometer after it is running to in-
sure that the case is running at the proper
temperature for the product.
A picture of this Electronic Tempera-
ture Control board layout and terminal loca-
tion is at the back of this book.
Electrical Enclosure –
The electrical enclosure contains the
defrost time clock and temperature control.
For servicing convenience, access is gained
by removing the access panel and electrical
box cover. The cabinet supply breakers
should be disconnected before removing the
enclosure cover.
Defrost Time Clock –
The timer is factory pre-set for two
(2) defrost cycles per day at 6:00 a.m. and
10:00 p.m. with a 40 minute failsafe. The
timer

Page 8
must be adjusted to the proper time of day
when the cabinet is started. The timer is ad-
justed by turning the knurled adjustment knob
in the center of the dial face counter-clockwise
until the time indicator corresponds with the
correct time of day. The defrost pins should be
checked for tightness. The timer the cabinet
has the lowest usage.will require readjusting
after a power failure or the cabinet supply is
turned off for extended periods of time. If an
additional defrost is required due to ambient or
cabinet usage conditions, do not put a defrost
during the middle of the day. Put any addi-
tional defrosts during the night or at a time
when the cabinet has the lowest usage.
Defrost is time initiated and temperature
terminated.
If the thermostat should fail, the timer is
equipped with a failsafe set at 40 minutes that
will allow defrost to terminate on time.
Thermometer –
The thermometer is located by looking
through the right hand door onto the right
hand end of the fan grill.
The Thermometer will also warm up
rather rapidly when the case door is held open
for a time such as when the case is being re-
stocked or a shopper is making a decision on a
product. After the door is closed it will take
some time for the thermometer to pull back
down to the case temperature. The thermome-
ter and temperature control sense discharge air
temp. which is 5-10° colder than the case tem-
perature.
The thermometer may be replaced by re-
moving the two screws holding it to the evapora-
tor fan grill. Lower the evaporator coil cover
by removing the brass screws located at the two
front corners of the cover, and backing out the
screws along the front edge of the cover holding
it to the grill. Follow the sensing lead to the cen-
ter rear of the evaporator coil. Loosen the clip
holding it to the bracket and slide the end of the
lead out.
When installing the new thermometer be
sure to run the lead of the new thermometer
through the hole in the fan grill first. Finish as-
sembly in reverse order. The same procedures
should be followed in the event you wish to clean
the end of the sensing lead.
Defrost Heater Thermostat –
The defrost heater thermostat is clamped
to the evaporator outlet tube. It is a bi-metal
thermostat that is tied in series with the evapora-
tor fans for a delay and with defrost time clock
solenoid to end defrost when the temperature
has been satisfied. The evaporator fans will not
come on until the thermostat senses 32° F and
defrost will terminate when the stat senses 58° F.
Defrost Heater Replacement –
The defrost heaters are firmly embedded
in the evaporator and held in place with spring
clips. To remove the heater, first remove all the
spring clips and pull the defective heater out of
the slots in the evaporator, starting at the wire
supply lead.
The replacement heater should be firmly
seated in the slots by using a small block of wood
and a mallet. After the new heater is in place,

Page 9
replace all of the spring retaining clips to assure
heater retention. One lead of the defective
heater may be used to pull the new leads
through the cabinet to the respective terminals
as marked on each lead.
NOTE - Care must be taken to make sure the
drain stub is correctly inserted in the cabinet
drain tube for proper drainage.
Lighting –
Electronically powered T-8 lamps lo-
cated inside each doorway provide interior
lighting. The tubes are enclosed in a patented
lens system to maintain proper heat around the
bulb for maximum light intensity and to protect
the product in case of breakage. See the An-
thony ELS instructions attached at the back of
this booklet for lens removal.
Each HGL model has a convenient ON/
OFF switch so lights may be turned off to con-
serve energy during hours when the store is
closed. The switch is located inside the cabinet
above the left-hand door. This switch only con-
trols the lights. 208-230 volt power must be
shut off at the main power supply source lo-
cated within the store prior to starting any ser-
vice or maintenance work.
Light ballast are located in mullions of the door
frames. See the Anthony ballast removal in-
structions at the back of the booklet.
Door Switches –
The switches at the top of the doorways
operate the evaporator fan motors. These
switches stop the fan motors when the doors are
open.
Door and Frame Heaters –
This cabinet is equipped with both
frame and door heaters. These are thermo-
statically controlled and will not come on until
the cabinet is at operating temperature. See
door mfg instructions for heater replace-
ment at the back of this booklet.
Alarm Thermostat (heater delay) –
The alarm (heater delay) thermostat is
located on the top of the inner liner in the up-
per right hand corner behind the evaporator.
The thermostat will not turn the heaters on
until it senses 0° and in turn will turn the
heaters off when it senses +18°F. This is so
that unwanted heat will not be added to the
case during defrost or if the case refrigeration
system fails.
Expansion Valve Adjustment –
Expansion valve must be adjusted to
fully feed the evaporator. Before attempting
to adjust the valve make sure the evaporator
is either clean or only lightly covered with
frost, and that the cabinet is within 10° of its
expected operation temperature. Adjust the
expansion valve as follows:
Attach two sensing probes to the
evaporator, one under the clamp holding the
expansion valve sensing bulb and the other

Page 10
securely taped to one of the return bends two
thirds of the way through the evaporator cir-
cuit. Some “hunting” of the expansion valve is
normal. The valve should be adjusted so that
during the hunting the greatest difference be-
tween the two probes is 3°F. Make adjustments
of no more than one half turn of the valve stem
at a time and wait for at least fifteen minutes
before rechecking probe temperature and mak-
ing further adjustments. Replace and tighten
cover of the valve stem.
Refrigeration –
As stated previously, these cases are self-
contained systems featuring semi-hermetic
compressors and thermostatic expansion valves.
The condensers are of a fin-and tube construc-
tion and should be periodically cleaned to main-
tain efficient operation.
If it should become necessary to leak test
the system; please adhere to the following no-
tice:
BECAUSE OF CFC ATMOSPHERIC CON-
SIDERATIONS BEING TAKEN TODAY, WE
ASK THAT LEAK TESTING BE DONE
WITH REFRIGERANT 22 MIXED WITH NI-
TROGEN. IF THE CONDENSING UNIT
NAMEPLATE DESIGNATES A REFRIGER-
ANT OTHER THAN R-22 REMOVE ALL R-
22 FROM THE IMMEDIATE AREA TO
AVOID CONFUSION AFTER LEAK TEST-
ING AND EVACUATING THE UNIT. RE-
CHARGE THE UNIT WITH PROPER RE-
FRIGERANT.
Leak Testing –
CAUTION
The test gas cylinder must be equipped
with a pressure gauge and regulator so that
system test pressures do not exceed maximum
allowable limits. Do not ever use anything
other than an R-22/Nitrogen mixture for leak
testing.
Attach a refrigerant test gas cylinder
to your service manifold and connect the
manifold to the charging port on the liquid
line valve. Charge an R-22/Nitrogen mixture
into the system, raising the pressure to the
unit’s nameplate for the low side and high
side pressures. Using an electronic detector,
carefully check the entire system for leaks.
Take special care to inspect all brazed and
flare connections.
Evacuation –
After the system is proven leak tight,
thoroughly evacuate the system according to
the following procedure:
 Discharge the refrigerant-nitrogen mix-
ture, allowing it to blow from the system
as rapidly as possible, into an empty cylin-
der. Be sure that all service valves and
solenoid valves are open to allow all of the
mixture to be discharged.
 Connect a deep-drain vacuum pump to
both the high and low side of the system.
Pull a vacuum on the system to at least
1500 microns.
 Break the vacuum by adding refrigerant
into the system until the pressure is above
0 psig. Always charge the refrigerant line
into the system through a new drier in the
charging manifold line. A 16 cubic inch
drier is sufficient for this purpose.

Page 11
 Repeat steps 2 and 3 two more times, the
third time evacuating the system to 500 mi-
crons.
Operational Data –
The following is typical data for HGL
models based on lab tests, and may vary under
field operating conditions. All data is based on
a discharge air temperature of -25°F and a re-
turn air temperature of -10°F. See chart below
CASE MODELS HGL-1/2 BS-TS HGL-3-BS/TS
Ambient Temperature 75°F 80°F 75°F 80°F

Suction Pressure (psi) 5-6 5-7 6 – 8 6 – 8
Refrigerant R-404A --------------------------------------------------
RECEIVER –
The receiver should not be confused for
a filter-drier or muffler. The receiver is in the
liquid line after the condenser and just ahead of
the filter-drier. The manufacturer may label
the receiver as a muffler or a drier but it is in
fact an empty shell.
CRANKCASE PRESSURE
REGULATOR –
The HGL-1 and 2 cases employ a crank-
case pressure regulator in the suction line. The
CPR is set for 10 psi. The purpose of the valve
is to maintain a low suction pressure on start-
up so that the compressor will start properly.
On start-up, the valve will hold the suction
pressure at the desired setting until the suction
pressure has dropped below the setting, then
the valve will open. If it becomes necessary to
check or reset the setting, the case must be
warm such as after a defrost cycle or from an
initial warm case condition.
Put a suction compound gauge on the compres-
sor suction valve, start the compressor. If the
pressure needs to be reduced turn the adjust-
ment screw clockwise or counterclockwise to
raise the pressure
DO NOT SET THE VALVE BASED ON THE
NAMEPLATE AMPERAGE RATING AS
THE PRESSURE SETTING WILL BE TOO
HIGH AND THE COMPRESSOR WILL
NOT START PROPERLY
