Installation

The ISLA FOOD COUNTER comes in various lengths and should be installed in a proper and uniform manner. The following guidelines will help ensure proper installation.

Case location should be near a floor sink or waste outlet – with electrical and refrigeration access usually under the case.
All plumbing should conform to local codes.
When the ISLA FOOD COUNTERS is to be installed in an existing fixture or in a supplied fixture, the ISLA FOOD COUNTERS and the new or existing fixture should be leveled front to back and side to side.
The electrical junction box is located under the ISLA FOOD COUNTERS which is where the electrical is terminated by the manufacturer. The junction box is a standard 2×4 box with knock-outs and cover.
The refrigeration is also stubbed down under the case for connection to liquid and suction lines from the remote ISLA FOOD COUNTERS case.
In cases where more that one ISLA FOOD COUNTERS are installed, run drains separately to the sink or drain outlet.
For ISLA FOOD COUNTERS units installed in an existing table, the lip on the unit should be sealed with a NSF approved sealant and all phillips screws slots should be sealed with same.
The ISLA FOOD COUNTERS should be dropped in the existing table oriented with the discharge air blowing from the front to the back of the fixture, the front is identifiable by the adjustable top air discharge control pins.
A thermostat and solenoid mounted in the suction line is recommended for temperature control and defrost.
Set defrost per case specs section of this book.

Exterior Loading
These models have not been structurally designed to support excessive external loading. Do not walk on their tops; This could cause serious personal injury and damage to the fixture.
Leveling
IMPORTANT! it is imperative that the ISLA FOOD COUNTER(s) and the FIXTURE that the ISLA FOOD COUNTER is installed in, be leveled from front to back and side to side prior to joining. a level case is necessary to ensure proper operation, water drainage.
NOTE:

A. To avoid removing concrete flooring, begin lineup leveling from the highest point of the store floor.
B. When wedges are involved in a lineup, set them first.

All cases were leveled and joined prior to shipment to insure the closest possible fit when cases are joined in the field. When joining, use a carpenters level and shim legs accordingly. Case must be raised correctly, under legs where support is best, to prevent damage to case.

Check level of floor where cases are to be set. Determine the highest point of the floor; cases will be set off this point.
Level and set the first case, carefully guiding the electrical, refrigeration and drain lines through the parent case. Case must be raised under legs where support is best to prevent damage to case. Internal bracing may be removed at this time.
Apply liberal bead of case joint sealant (NSF Approved) to cover dotted area shown below.

DO NOT USE PERMAGUM!

Proper case-joint sealing is extremely important to prevent water leaks!
It is the contractor’s responsibility to install case(s) according to local construction and health codes
BUILT IN TWO SECTIONS
All cases were leveled and joined and prior to shipment to insure the closest possible fit when cases are joined in the field. To avoid removing concrete flooring, begin line-up leveling from the highest point of the store floor.
It is imperative that the case be leveled from front to back and side to side. A level case is necessary to insure proper operation of mechanical systems.

Bumper installation instructions

HUSSMANN-IM-FR-Isla-Food-Counters-fig
8

Step 1: Make sure the aluminum channel and end caps are installed.
Step 2: Use silicone lubricant to help the bumper slide into the channel.
Step 3: Starting on one end: while inserting the bumper, push it up against the end cap to prevent the bumper from shrinking after installation(when it gets cold).
Step 4: As you insert the bumper into the channel with one hand, pull the bumper toward you with the other to open the inside lips. Slowly apply pressure by rolling the bumper into the track.

Plumbing

Waste Outlet and P-TRAP
The waste outlet is located at the left hand end of these fixtures allowing drip piping to be run under the fixture lengthwise.
A 1” P-TRAP and threaded adapter are supplied with each fixture. The P-TRAP must be installed to prevent air leakage and insect entrance into the fixture.

installing Condensate Drain
Poorly or improperly installed condensate drains can seriously interfere with the operation of this refrigerator, and result in costly maintenance and product losses. Please follow the recommendations listed below when installing condensate drains to insure a proper installation:

Never use pipe for condensate drains smaller than the nominal diameter of the pipe or P-TRAP supplied with the case.
When connecting condensate drains, the P-TRAP must be used as part of the condensate drain to prevent air leakage or insect entrance. Store plumbing system floor drains should be at least 14” off the center of the case to allow use of the P-TRAP pipe section. Never use two water seals in series in any one line. Double P-TRAPS in series will cause a lock and prevent draining.
Always provide as much down hill slope (“fall”) as possible; 1/8” per foot is the preferred minimum. PVC pipe, when used, must be supported to maintain the 1/8” pitch and to prevent warping.
Avoid long runs of condensate drains. Long runs make it impossible to provide the “fall” necessary for good drainage.
Provide a suitable air break between the flood rim of the floor drain and outlet of condensate drain. 1” is ideal.
Prevent condensate drains from freezing:
- a. Do not install condensate drains in contact with non-insulated suction lines. Suction lines should be insulated with a non absorbent insulation material such as Armstrong’s Armaflex.
- b. Where condensate drains are located in dead air spaces (between refrigerators or between a refrigerator and a wall), provide means to prevent freezing. The water seal should be insulated to prevent condensation.

Refrigeration

Refrigerant Type
The standard refrigerant will be R-404A unless otherwise specified on the customer order. Check the serial plate on the case for information.

Piping
The refrigerant line outlets are piped through the rear of the fixture at the left hand end when viewed from the back. Insulate suction lines to prevent condensation from dripping.

Refrigeration Lines

Liquid Suction 3/8” O.D. 5/8” O.D.

NOTE: The standard coil is piped at 5/8” (suction); however, the store tie-in may vary depending on the number of coils and the draw the case has. Depending on the case setup, the connecting point in the store may be 5/8”, 7/8”, or 11/8”. Refer to the particular case you are hooking up.
Refrigerant lines should be sized as shown on the refrigeration legend furnished by the store. install P-TRAPS (oil traps) at the base of all suction line vertical risers.

Pressure drop can rob the system of capacity. To keep the pressure drop to a minimum, keep refrigerant line run as short as possible, using the minimum number of elbows. Where elbows are required, use long radius elbows only.

Control Settings
Maintain these parameters to achieve near constant product temperatures. Product temperature should be measured first thing in the morning, after having been refrigerated overnight. For all multiplexing, defrost should be time terminated. Loadmaster valves are not recommended. The number of defrosts per day should never change. The duration of the defrost cycle may be adjusted to meet conditions present at your location.

Evaporator Fans
The evaporator fans are located at the center front of these merchandisers directly beneath the display pans. FOR ACCESS TO THE FANS: Remove the right handdeck pan as viewed from the front of the case.

Acccess to TX Valves and Drain Lines

Mechanical – Remove product from end of case. Remove product racks. Remove refrigeration and drain access panels (labeled). TX valve (mechanical only) and drain are located under each access panel at end of the case.
Electronic – The Electronic Expansion valve master and slave cylinder(s) are located within the electrical access panel(s).
Electronic Expansion valve (Optional)
A wide variety of electronic expansion valves and case controllers can be utilized. Please refer to EEV and controller manufacturers information sheet. Sensors for electronic expansion valves will be installed on the coil inlet, coil outlet, and in the discharge air. (Some supermarkets require a 4th sensor in the return air).
Case controllers will be located in the electrical raceway or under the case.

Thermostatic Expansion Valve Location
This device is located on the same side as the refrigeration stub. A Sporlan balanced port expansion valve model is furnished as standard equipment, unless otherwise specified by customer.

Expansion Adjustment
Expansion valves must be adjusted to fully feed the evaporator. Before attempting any adjustments, make sure the evaporator is either clear or very lightly covered with frost, and that the fixture is within 10°F of its expected operating temperature.
Measuring the Operating Superheat

Determine the suction pressure with an accurate pressure gauge at the evaporator outlet.
From a refrigerant pressure temperature chart, determine the saturation temperature at the observed suction pressure.
Measure the temperature of the suction gas at the thermostatic remote bulb location.
Subtract the saturation temperature obtained in step No. from the temperature measured in step No. 3.
The difference is superheat.
Set the superheat for 5°F – 7°F.

T-STAT Location
T-STATS are located within the electrical raceway.

Electrical

HUSSMANN-IM-FR-Isla-Food-Counters-fig 9

CASE MUST BE GROUNDED
NOTE: Refer to label illustrated above that is affixed to case to determine the actual configuration as checked in the “TYPE iNsTall ED” boxes.

Electrical Circuit Identification
Standard lighting for all models will be full length fluorescent lamps located within the case at the top.
The switch controlling the lights, the plug provided for digital scale, and the thermometer are located at the rear of the case mullion.
The receptacle that is provided on the exterior back of these models is intended for computerized scales with a five amp maximum load, not for large motors or other high wattage appliances. It should be wired to a dedicated circuit.

Electrical service Receptacles (When a pplicable)
The receptacles located on the exterior of the merchandiser are intended for scales and lighted displays. They are not intended nor suitable for large motors or other external appliances.

BEFORE SERVICING
ALWAYS DISCONNECT ELECTRICAL POWER AT THE MAIN DISCONNECT WHEN SERVICING OR REPLACING ANY ELECTRICAL COMPONENT.
This includes (but not limited to) Heaters and Lights.

Field Wiring and Serial Plate Amperage
Field Wiring must be sized for component amperes printed on the serial plate. Actual ampere draw may be less than specified. Field wiring from the refrigeration control panel to the merchandisers is required for refrigeration thermostats.
Case amperes are listed on the wiring diagram, but always check the serial plate.

Ballast Location
Ballasts are located within the access panel.

User Information

Hot Well/Soup Well Operating Instructions
Each hot unit has an individual heater with a separate control. These are thermostatically controlled with an indicator light showing when the heater has cycled on and is heating. The light below each control knob indicates when the well heater is heating. HUSSMANN-IM-FR-Isla-Food-Counters-fig

These units are for short-term holding and display of precooked hot foods. They are not intended to cool or reheat food. The temperature of the food entering the display should be approximately 160°F when first inserted.
Any attempt to use the hot unit to display large amounts of food or soup for long periods of time will result in dehydrated, overcooked and unsafe food. The quality of the food will progressively worsen as the length of time increases.
The deterioration of product quality is a function of time and temperature. All products are affected even though in gravy or other liquid. They may appear to withstand the temperature better than “dry” foods such as fried chicken but this is not necessarily true. All foods will continue to be affected by prolonged exposure to elevated temperatures.
The following guidelines are provided only as a general guide for the use of this equipment. The local health agency for your area can provide specific temperature requirements.
Critical attention must be given to the heat controls for these hot tables/soup bars. Both the upper and lower heat controls (soup only require lower control) must be adjusted to achieve proper food temperatures. Hot foods should be held at a constant temperature of at least 140°F (60°C) (minimum FDA requirements to prevent spoiling). However, increasing the temperature too high will also cause the food to overcook, dry out, lose its flavor, texture and color. Food held for prolonged periods at high temperatures will also lose some of their nutritional value.
Different foods require different control settings. The type of food, the quantities of food and length of time that it is to remain in the hot table must be considered when establishing control settings. Therefore, it must be the user’s responsibility to establish the correct control settings to maintain the food at the safest, tastiest and saleable condition. HUSSMANN-
IM-FR-Isla-Food-Counters-fig 11

To fill the well:

Turn the fill valve to open position.
Close the drain valve.

To drain the well:

Turn the fill valve to the closed position.
Open the drain valve.

Operation:

Turn power switch on.
Set temperature control to ‘7” setting. Adjust as necessary.
Adjust overhead heater as necessary.

Shutting down:

Turn “ON” switch off.
Close fill valve.
Open drain valve.
Once the water is drained, close the drain valve.

Overhead Heating system
Overhead heaters and fluorescent lights are located above each well to provide both top heat and illumination.
To obtain the proper food temperatures, the well heater and overhead heater must be adjusted. Maximum limits should be avoided to prevent overcooking or drying out of food.
Note: Soup Wells do not have overhead heaters.

food temperatures can be accurately determined only through the use of food thermometers!

Important Food Handling Tips:

Preheat case 30 minutes before loading product.
Never place food directly into the warmer. Always use an inset.
Food must be displayed in a single layer, in contact with the heat source at all times.
Using thermometer, check product before loading in case (150°-160°).
At start, set control to “7”. After loading, recheck temperature every ½ hour to see that unit is operating properly. Adjust the temperature to maintain a product temperature of 140°F (60°C) and above. The setting will depend on the type and quantity of product being displayed. Be sure to test product temperature with a thermometer frequently for good product maintenance.
Food should be rotated periodically.
At the end of the day, remove product and let case cool. Then clean with soap and water.

Do not run hot wells without any water!

General Cleaning

Case Cleaning
Long life and satisfactory performance of any equipment are dependent upon the care given to it. To insure long life, proper sanitation and minimum maintenance costs, the unit should be cleaned thoroughly and frequently.
The interior may be cleaned with any domestic soap or detergent based cleaners. Sanitizing solutions will not harm the interior bottom, however, these solutions should always be used according to the manufacturer’s directions. It is essential to establish and regulate cleaning procedures. This will minimize bacteria causing discoloration which leads to degraded product appearance and significantly shortening product shelf life.
Soap and hot water are not enough to kill this bacteria. A sanitizing solution must be included with each cleaning process to eliminate this bacteria.

Scrub thoroughly, cleaning all surfaces, with soap and hot water.
Rinse with hot water, but do not flood.
Apply the sanitizing solution according to the manufacturer’s directions.
Rinse thoroughly.
Dry completely before resuming operation.

Cleaning Glass and Mirrors
Only use a soft cloth and mild glass cleaner for cleaning any glass or mirrored components. Be sure to rinse and/or dry completely.
Never use hot water on cold glass surfaces! It may shatter and cause serious injury! Allow glass surfaces to warm first.

CAUTION

CLEANING PRECAUTIONS
When cleaning:

Do not use high pressure water hoses
Do not introduce water faster then waste outlet can drain
NEVER INTRODUCE WATER ON SELF CONTAINED UNIT WITH AN EVPORATOR PAN
NEVER USE A CLEANING OR SANITIZING SOLUTION THAT HAS AN OIL BASE (these will dissolve the butyl sealants) or an AMMONA BASE (this will corrode the copper components of the case)
TO PRESERVE THE ATTRACTIVE FINISH:
DO USE WATER AND A MILD DETERGENT FOR THE EXTERIOR ONLY
DO NOT USE A CHLORANITED CLEANER ON ANY SURFACE
DO NOT USE ABRASIVES OR STEEL WOOL SCOURING PADS (these will mar the finish)

Plexi-glass and Acrylic Care

Improper cleaning not only accelerates the cleaning cycle but also degrades the quality of this surface. Normal daily buffing motions can generated static cling attracting dust to the surface. Incorrect cleaning agents or cleaning cloths can cause micro scratching of the surface, causing the plastic to haze over time.

Cleaning
Hussmann recommends using a clean damp chamois, or a paper towel marketed as dust and abrasive free with 210® Plastic Cleaner and Polish available by calling Sumner Labs at 1-800-542-8656. Hard, rough cloths or paper towels will scratch the acrylic and should not be used.

Antistatic Coatings
The 210® has proven to be very effective in not only cleaning and polishing the Plexiglass surface, but also providing antistatic and anti-fog capabilities. This product also seals pores and provides a protective coating.

Cold Food
Stocking
Improper temperature and lighting will cause serious product loss. Discoloration, dehydration and spoilage can be controlled with proper use of the equipment and handling of product. Product temperature should always be maintained at a constant and proper temperature. This means that from the time the product is received, through storage, preparation and display, the temperature of the product must be controlled to maximize life of the product. Hussmann cases were not designed to “heat up” or “cool down” product – but rather to maintain an item’s proper temperature for maximum shelf life. To achieve the protection required always:

Minimize processing time to avoid damaging temperature rise to the product. Product should be at proper temperature.
Keep the air in and around the case area free of foreign gasses and fumes or food will rapidly deteriorate.
Maintain the display merchandisers temperature controls as outlined in the refrigerator section of this manual.
Do not place any product into these refrigerators until all controls have been adjusted and they are operating at the proper temperature. Allow merchandiser to operate a minimum of 6 hours before stocking with any product.
When stocking, never allow the product to extend beyond the recommended load limit. Air discharge and return air flue must be unobstructed at all times to provide proper refrigeration. Do not stock product within the top air discharge zone (See diagram).
This case was designed and tested using stainless steel hotel pans. The use of any other material (such as crocks) may insulate the product and thus, not be kept cold. Containers made of materials other than stainless steel is discouraged and may void warranty.
Avoid the use of supplemental flood or spot lighting. Display light intensity has been designed for maximum visibility and product life at the factory.
The use of higher output fluorescent lamps (H.O. and V.H.O.), will shorten the shelf life of the product.

Important Steps

Do not set temperature too cold, as this causes product dehydration. Refer to case specs section for proper settings.
Temperature control should be by means of a T-STAT and Suction Stop Solenoid at each case. Do not use EPR valves, Liquid Line Solenoids or electronic control devices of any kind, as these allow temperature swings causing dehydration and excessive energy consumption.

Case Cleaning
Long life and satisfactory performance of any equipment are dependent upon the care given to it. To insure long life, proper sanitation and minimum maintenance costs, the refrigerator should be thoroughly cleaned frequently.
SHUT OFF FAN DURING CLEANING PROCESS. It can be unplugged within the case, or shut off case at the source. The interior bottom may be cleaned with any domestic soap or detergent based cleaners. Sanitizing solutions will not harm the interior bottom, however, these solutions should always be used according to the manufacturer’s directions. It is essential to establish and regulate cleaning procedures. This will minimize bacteria causing discoloration which leads to degraded product appearance and significantly shortening product shelf life.
Soap and hot water are not enough to kill this bacteria. A sanitizing solution must be included with each cleaning process to eliminate this bacteria.

Scrub thoroughly, cleaning all surfaces, with soap and hot water.
Rinse with hot water, but do not flood.
Apply the sanitizing solution according to the manufacturer’s directions.
Rinse thoroughly.
Dry completely before resuming operation.

Cleaning Glass and Mirrors
Only use a soft cloth and mild glass cleaner for cleaning any glass or mirrored components. Be sure to rinse and/or dry completely.
Never use hot water on cold glass surfaces! it may shatter and cause serious injury! Allow glass surfaces to warm first.

Hussmann recommends using #15 Sil-Fos for repairs.

Tips and Troubleshooting
Before calling for service, check the following:

Check electrical power supply to the equipment for connection.
Check fixture loading. Overstocking case will affect its proper operation.
If frost is collecting on fixture and/or product, check that Humidity Control is working properly, and that no outside doors or windows are open-allowing moisture to enter store.

FOR PROMPT SERVICE
When contacting the factory, be sure to have the Case Model and Serial Number handy. This information is on a plate located on the case itself.

Stainless Steel Cleaning and Care

There are three basic things, which can break down your stainless steel’s passivity layer and allow corrosion.

Mechanical a brasion
Mechanical Abrasion means those things that will scratch the steels surface. Steel Pads, wire Brushes, and Scrapers are prime examples.
Water
Water comes out of our tap in varying degrees of hardness. Depending on what part of the country you live in, you may have hard or soft water. Hard water may leave spots. Also, when heated, hard water leaves deposits behind that if left to sit, will break down the passive layer and rust your stainless steel. Other deposits from food preparation and service must be properly removed.
Chlorides
Chlorides are found nearly everywhere. They are in water, food and table salt. One of the worst perpetrators of chlorides can come from household and industrial cleaners.

Don’t Despair! Here are a few steps that can help prevent stainless steel rust.

Use the Proper Tools
When cleaning your stainless steel products, take care to use non-abrasive tools. Soft Clothes and plastic scouring pads will NOT harm the steel’s passive layer. Stainless steel pads can also be used but the scrubbing motion must be in the same direction of the manufacturer’s polishing marks.
Clean With the Polish lines
Some stainless steels come with visible polishing lines or “grain”. When visible lines are present, you should ALWAYS scrub in a motion that is parallel to them. When the grain cannot be seen, play it safe and use a soft cloth or plastic scouring pad.
Use alkaline, or Non-chloride Containing Cleaners
While many traditional cleaners are loaded with chlorides, the industry is providing an ever increasing choice of non-chloride cleaners. If you are not sure of your cleaner’s chloride content contact your cleaner supplier. If they tell you that your present cleaner contains chlorides, ask for an alternative. Also, avoid cleaners containing quaternary salts as they also can attack stainless steel & cause pitting and rusting.
Treat your Water
Though this is not always practical, softening hard water can do much to reduce deposits. There are certain filters that can be installed to remove distasteful and corrosive elements. Salts in a properly maintained water softener are your friends. If you are not sure of the proper water treatment, call a treatment specialist.
Keep your Food Equipment Clean
Use alkaline, alkaline chlorinated or non-chlorinated cleaners at recommended strength. Clean frequently to avoid build-up of hard, stubborn stains. If you boil water in your stainless steel equipment, remember the single most likely cause of damage is chlorides in the water. Heating cleaners that contain chlorides has a similar effect.
RINSE, RINSE, RINSE
If chlorinated cleaners are used you must rinse, rinse, rinse and wipe dry immediately. The sooner you wipe off standing water, especially when sit contains cleaning agents, the better. After wiping the equipment down, allow it to air dry for the oxygen helps maintain the stainless steel’s passivity film.
Never Use Hydrochloric acid (Muriatic acid) on Stainless Steel.
Regularly Restore/Passivate Stainless Steel.

CLEANING COILS
Never use sharp objects around coils. Use a soft brush or vacuum brush to clean debris from coils. Do not puncture coils! Do not bend fins. Contact an authorized service technician if a coil is punctured, cracked, or otherwise damaged.

Do NOT use chlorine or ammonia-based cleaners to clean aluminum coils.
ICE in or on the coil indicates the refrigeration and defrost cycle is not operating properly. Contact an authorized service technician to determine the cause of icing, and to make adjustments as necessary. To maintain product integrity, move all product to a cooler until the unit has returned to normal operating temperatures.
