INTRODUCTION
The Hussmann Model GSVM open vertical merchandiser offers versatility in the display of medium temperature (35-41ºF) products such as diary products, prepared salads, pizza and fresh entrees that are pre-chilled in a cooler. So that you can realize maximum benefit from this fine piece of equipment we urge both you and your installer to carefully read and follow this brief set of instructions prior to installation of the equipment.

INSPECTION
The equipment has been skidded and crated prior to shipment from the factory. It is the carrier’s responsibility to deliver it to you in good condition until such time as you sign for it.
Upon receipt of the cabinet, examine the packaging for damage. If the packaging is damaged, make specific notation on the delivery ticket as to the location and extent of damage prior to signing for the piece. Carefully remove packaging and examine the cabinet for damage. If damage is found, contact the delivering carrier immediately and request that his agent prepare an inspection report for the purpose of filing a claim. THIS IS YOUR RESPONSIBILITY, NOT THE FACTORY’S.
Save all packaging materials and move the cabinet as little as possible prior to inspection.

LOCATION and CLEARANCE
It is important that careful consideration be given to locating the cabinet away from an area where direct sunlight would shine into the fixture, or where drafts from air conditioning grilles, fans, and open doors could affect its operation. The GSVM4060 and 4072 have front condenser air intake and discharge. A minimum distance of two feet must be left open in front of the case so that air discharge and intake to the condensing unit is not obstructed. The GSVM5272 model requires a 5″ minimum clearance behind the case and clear above the case since it has straight through condenser air flow. Brackets are provided for field attachment to obtain the 5″ spacing.

SKID
The skid should be left on the cabinet until it is near its final location. The skid provides protection for both case and floor. The skid is removed by raising one end of the case approx. 6″, block securely and remove the 2 skid bolts on the raised end – then screw back into the holes 2 leg levelers. The procedure is repeated on the op-posite end. When the leg levelers are in place, the case may be slid off the skid and placed in its final location.

LEVELING
The cabinet must be leveled properly to insure full drainage of condens ate water from the evaporator coil. Level the case from front to rear and end to end. Standard levelers , packed ins ide the case, or optional legs can be provided for this purpose.

SEALING
Once the case is properly leveled, the case should be sealed to the floor as shown in the following drawing, using an NSF approved material such as General Electric RTV-102 silicone sealer or equivalent.

• Silicone Sealant Floor

ACCESS PANEL REMOVAL
The louvered access panel on the lower front of the case provides access to the condensing unit, electrical box and condensate pan. Remove panel by removing screw at bottom and lifting up and pulling forward.

DRAINS
Remote draining is not required in self-contained models. The condensate water from the evaporator drains out through the bottom of the cabinet, through a copper trap attached to the underside and into the condensing unit compartment to a heated condensate pan. Until this trap gets filled with water from the initial defrost, there may be a small frost buildup in the coil area on startup, which should disappear after the first defrost. The pan uses a thermistor to sense the presence of water in the pan and adjusts the amount of heat required to evaporate the water.

LEGS (OPTIONAL)
If required by Health Inspectors the levelers can be removed and replaced with NSF Approved legs to raise the case 6 inches for cleaning purposes. An optional skirt kit can be provided to clip on to the legs.

SERIAL PLATE
The serial plate is located on the interior top wall of the cabinet towards the left end. It contains all pertinent information such as model, cabinet serial number, amperage rating, refrigerant type and charge, etc. This information will be needed to install, service, or order parts for this piece of equipment.

AIR DISTRIBUTION and PRODUCT LOADING
This cabinet has a forced-air circulation system. Air flows through the back wall over the product on the shelves, as well as out the honeycomb diffuser located above the product, across the face of the product (air curtain) and into the return air grill. Do not load product so that it extends over the shelf edges or over the return air grille.

POWER REQUIREMENTS
The GSVM Models are equipped for operation on a 115/60/1 power supply. See chart in specifications for requirements. It is very important for the safety of both you and your customer to have each circuit properly grounded. A qualified electrician should perform all wiring in accordance with the National Electrical Code and/or all local codes. Separate circuits are recommended for each case in order to prevent product loss due to overloading or malfunction of other equipment on the same circuit. For proper operation of equipment, voltage as measured at the compressor must not vary more than 5% from the cabinet serial plate rating. If either a high or low voltage condition exists, contact your electrician, local power company, or equipment manufacturer.

ELECTRICAL BOX
The electrical box is located behind the louvered access panel. The box is capable of sliding out for service after the hold down screw is removed. The box contains the power switch and defrost time clock.

POWER SWITCH
The main power switch is located behind the front louvered access panel on the side of the electrical box. This power switch controls all power to the case. THE CABINET POWER SWITCH MUST BE IN THE OFF POSITION BEFORE STARTING ANY CLEANING OR SERVICE WORK ON THE EQUIPMENT.

DEFROST TIME CLOCK

The time clock, located in the electrical box, provides a definite off-time so that the evaporator will clear itself of frost. The clock is provided with pins to initiate defrost. The failsafe setting sets the length of defrost (from 2 minutes minimum to 110 maximum). The clock is factory pre-set for 3 defrosts (at 6 a.m. , 2 p.m. and 10 p.m.) on the 4060 and 4072 at 20 minutes each. There are 4 defrost on the 5272 (2 a.m., 8 a.m., 2 p.m., and 8 p.m.) at 30 minutes each Additional defrost may be required for cases located in high humidity or high us age cases. If possible, avoid setting a defrost during the day, or peak usage periods. THE CLOCK TIME POINTER SHOULD BE SET TO THE CORRECT TIME OF DAY WHEN THE CABINET IS READY TO BE STARTED.
Setting the timer – Extra pins are pro-vided with the timer.

• Put pin in hole of dial face at the time you wish the cabinet to defrost. Note that there is an AM and PM section on the dial face. Be sure the pin is tight.
• Set the length of time for the defrost (failsafe). Push down on the adjustment and slide it to the length of time. Do not set the time longer than 60 minutes.
• Set the time pointer to the proper time of day and start cabinet.

CONNECTIONS

• Check cabinet thoroughly for loose nuts and bolts and electrical connections.
• Inspect the refrigeration lines for any visible damage or chafing.
• Replace electrical box cover.
• Replace the louvered access panel.
• Start the cabinet and allow to pull down to operating temperature before loading.

SHELVING MAXIMUM WEIGHT CAPACITY (LBS)
The following is a tabulation of the maximum evenly distributed weights that can be applied on the respective shelves. They greatly exceed most normal food products that could be displayed in the case

OPERATION and MAINTENANCE

It is important that the two previous sections of this installation booklet have been read and followed carefully before attempting to start up the equipment. A thorough inspection should be made prior to start up to assure that there are no loose nuts, bolts, electrical connections or refrigeration lines rubbing or chafing. Turn the power switch to the ON position. ALLOW system to reach normal operating temp. prior to loading any product. This cabinet has a forced-air curtain that flows over the top of the product.

See SHELVES for the special loading instructions. Air flows out of the honeycomb diffuser located above the product, across the product, and into the return duct. The honeycomb can be removed for cleaning.

TEMPERATURE CONTROL
Interior cabinet temperatures are controlled through the use of a bulb and capillary type temperature control. The control is located in the electrical box. The sensing bulb is mounted on the top of the evaporator coil on the 4060 and 4072. On the 5272 it is located on the rear wall behind the evaporator coil. Be sure to disconnect power supply prior to any service work on the control. The control is factory pre-set between 19º and 21ºF for the GSVM4060, 4072 and – 26º to 28ºF on the GSVM5272 to maintain between 35º and 40ºF interior cabinet average temperatures. The differential is set at 8-10ºF or a little over halfway towards “MAX”. Do not adjust lower or evap. icing will occur. It can be adjusted to other desired temperatures by turning the dial to the corresponding dial face temperatures. The indicated dial temperature will not directly correspond to the actual cabinet temperature due to the bulb location and depending on various conditions, a certain amount of time lag will be noticed between the new setting and the resulting temperature.

CONDENSING UNIT
A regular program should be set up for cleaning the fin-and-tube condenser. Normally, this cleaning is required every 3 to 4 months, but the individual store application may shorten or lengthen this time period. Dust and dirt accumulation can cause serious efficiency loss. Access is gained to the unit area by removing the louvered grille. Before at-tempting to slide out condensing unit you must first remove the screws from the con-denser unit baffles. The unit slides for-ward to facilitate cleaning and for service. Care should be taken when pushing the unit back in, to insure that the pullout coil does not become kinked or damaged in some way. The baffle screws must be re- placed after sliding the condensing unit back into position. Double check to make sure the drain hos e is in the drain pan be-fore putting the access grille back on. The rear access panel is also removable if it is necessary to work at the back of the case.

SHELVES
The GSVM4060 cabinet is equipped with 2 standard s helves for the display of your product. The 13” shelf should be located at the top and 15” shelf should be located below it. The GSVM5272 and 4072  has an additional 13” shelf as standard which should be located above the 15” shelf also. The shelves should be positioned so they do not protrude into the front (top to bottom) air curtain. Do not use deeper shelves or allow product to protrude over the shelves into the air curtain.

THERMOMETER
A solar thermometer is provided that registers degrees ºF. The thermometer is located in the front center. A solar powered thermometer is equipped with each cabinet. The thermometer is located in the top front center of the cabinet interior. Temperature is dis-played in Fahrenheit degrees as standard. Celsius display is available as an option. The thermometer may be replaced by removing the two s crews securing the thermometer to is mounting bracket. Re-move the sensing element from the clip. Install the new thermometer in reverse or-der.
To clean the sensing element of the thermometer, follow the same procedure as replacement. Cleaning of the element is accomplished by using water and mild detergent. Be sure to wipe the element clean of any residues s o proper temperatures are displayed.

LIGHTING
Interior lighting is provided by a cool white fluorescent bulb under the top header (standard), and additional lights under each shelf. The tubes are sleeved to maintain proper heat around the bulb for maximum light intensity and to protect the product in case of breakage. The tubes can be replaced without removing shelves or product. To replace the bulb, twist th e bulb and slide the prongs clear of the lamp holder. When re-installing this type of bulb, be sure the prongs on the bulb twist and lock into place.

LIGHT SWITCH (es)
The standard case has one upper light with a switch located under the top left end behind the honeycomb. Addition-ally, the lighting on each shelf has a separate switch located under the center of each shelf.

BALLAST (s)
The ballast for the top standard light is located in the electrical box. Access is gained by removing the access panel. Access to the shelving ballasts is gained by removing the respective shelf (after u n-plugging the harness), and removing the three screws from the ballast cover.

CLEANING EXTERIOR
When cleaning the exterior of the cabinet, use a soft cloth or sponges with water and a mild detergent. Rinse and wipe dry. Do not use an abrasive cleanser on the painted surfaces as this will mar the finish. For plexiglass windows, use an a p-proved plexiglass cleaner such as Craftics 20/20 Plasti -Cleaner.

CLEANING INTERIOR
For cleaning the interior of the product compartment, remove the product, disconnect the electrical power, and allow cabinet to warm to room temperature. Use a soft cloth or sponge with a mild detergent to wash the interior. The drainage area and drain should be checked to insure that they have not be-come clogged. If the condensate drain hose is removed from the electric condensate pan for cleaning, it must be reinstalled prior to operating the case. Do not use an abrasive cleanser on the painted surfaces GSVM-4060 only has Electric Condensate Pan as Standard Wipe dry before restarting the cabinet. The time clock (see Defrost Time Clock section) should be reset to the correct time of day. Allow the cabinet to cool down to proper temperature before reloading product.

CLEANING STAINLESS STEEL SURFACES
Generally soap and water will be sufficient for most cleanings when done of- ten and regularly. When necessary, several cleaning agents can be used. Some of themare Comet, Bab-O, Liquid NuSteel, Cooper’s Stainless Steel Cleaner, and Al-len’s Stainless Steel Cleaner.

REFRIGERATION
The GSVM models employ a refrigeration system using a hermetic compressor. The GSVM4060 and GSVM4072 systems employ a capillary tube for refrigerant flow control. The capillary tube is soldered to the suction line pull-out coil for proper heat exchange. If the capillary should become plugged or damaged for some reason it is best to replace the whole heat exchanger with a new one. Consult the factory for the proper replacement. The GSVM-5272 employs a bleed port type expansion valve for proper refrigerant control. As stated previously, these cases are self-contained with the condensing unit mounted at the bottom. They are equipped with a hermetic compressor and a capillary tube. The condenser is of fin and tube construction and SHOULD BE PERIODICALLY CLEANED TO MAIN-TAIN EFFICIENT OPERATION.
If for any reason the cabinet must be recharged, consult the serial plate found inside the cabinet for the proper refrigerant charge and weight. If it should become necessary to leak test the system, please adhere to the following notice: BECAUSE OF THE CFC ATMOS-PHERIC CONSIDERATIONS BEING TAKEN TODAY, WE ASK THAT LEAK TESTING BE DONE WITH REFRIGER-ANT 22 MIXED WITH NITROGEN

LEAK TESTING
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 a 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 s ide and high side pressures. Using an electronic detec-tor, 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 mixture, allowing it to blow from the system as rapidly as possible, into any empty cylinder. Be sure that all service valves are open to al-low 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.
• Repeat steps 2 and 3 two more times, the third time evacuating the system to 500 microns.

The following pressures are optimum when the case in a 75º to 80ºF ambient and is running from 35º to 40ºF cabinet temperature and are for reference only:

MODEL NO.| REFRIGERANT TYPE| SUCTION PRESSURE
(psig)| HEAD PRESSURE
(psig)
---|---|---|---
GSVM4060| R- 134a| 12-15| 130-150
| | |
GSVM4072| R- 134a| 12-15| 130-150
| | |
GSVM5272| R- 134a| 14-18| 130-150
GSVM5272| R- 404A| 40-50| 310-320

Consult the serial plate for the correct refrigerant charge. This charge is critical and should be weighed in.

TEMPERATURE CONTROL

The temperature control is located in the electrical box. The sensing bulb is located on the left hand end of the lower back wall. When replacing make sure the bulb is in the proper location and that the hole in the liner is properly sealed after the replacement has been made. The control is adjustable from –30º to 50ºF (dial face marking). The actual cabinet
temperature is approximately 6 to 9º warmer than the control setting so this must be taken into consideration. The control also has an adjustable differential that determines the difference between the cut-in and cut-out temperature. This is adjustable from 5 to 20º. The factory set-ting is from 8-10º to insure proper off time to keep the evaporator from icing.

EVAPORATOR FAN MOTORS
To replace an evaporator fan motor, the product must be removed from the cabinet and the bottom shelf also removed. Next, remove the plate covering the fans by removing the 2 screws, and 4 bolts holding this in place. The fans are now ac-
