INSTALLATION

5.1 Location
This unit is intended for indoor use only.
Be sure the location chosen for your unit must be able to provide good air circulation for most efficient refrigeration.
Avoid locations near heat sources such as stoves, ovens, fryers, and also direct sunlight where temperatures can reach extreme values. Besides, do not select a location in an area where temperatures may drop below 55ºF or increase more than 90ºF.
You should allow enough clearance between the unit and the side walls in order to make use of the stay open feature of doors at 120º. The doors must be able to open a minimum of 90º in order to make use of the maximum clear door width.
Furthermore, the floor at the final location must be strong enough to support the total weight of the cabinet lus the maximum product load. Also, it must be level and free of vibration. Reinforce the floor if necessary.
5.2 Uncrating
Back-Bar and Merchandiser ERC 110 are shipped on a wooden pallet in stretch wrapped material and wood crate.
First remove the plastic cover and then unscrew the wooden frame.
Merchandiser ERC 180 is shipped on a wooden pallet in stretch wrapped material and a wood frame. First remove the plastic cover and then remove the screws on the wooden frame.
All packaging materials used are environmentally friendly and may be recycled or reused. Actively contribute to the protection of the environment by insisting on packaging recovery and removal methods that are environmentally friendly.
NOTE: We do not recommend laying the unit down on its front, side or back. However, you must be certain to allow the unit to remain in an upright position afterwards for at least 24 hours before plugging it in so that the compressor oil and refrigerant may settle.
5.3 Ventilation
To assure maximum operating efficiency, the equipment should be located where a continuous air supply can circulate around the cabinet. To maintain a proper air flow, a minimum of 30″ on the front of the unit must be provided.
Restricting the air supply will generate an excessive heat load on the condensing unit and adversely affect it operating efficiency. Do not at any time obstruct the grill area in the front of the cabinet in any way. 5.4 Leveling
Its extremely important that the cabinet is perfectly level for proper operation so that the drain pan will drain
properly, the doors will line up with the frames and the unit will not be subject to undue strain.
We install feet adjustable from factory. You can adjust these feet as you wish
5.5 Sealing Case to Floor
To maintain NSF Sanitation listing cases must sealed to the floor.
Use NSF sealant such as silicone or equivalent cove mouldings or tiles are acceptable.
Do not block any louvered holes. 5.6 Initial cleaning procedure
Before starting-up and placing any food inside the cabinet, firstly remove the protective film and then clean the complete unit thoroughly. If any adhesiv eremains, eliminate it with alcohol. Washing with a mild soap and warm water solution is recommended for cleaning all the stainless-steel surfaces of your cabinet. This should be followed by cleaning with a baking soda solution. Rinse thoroughly with clear water and dry with a clean, soft cloth.
NOTE: Never use abrasive or harsh cleaners, concentrated detergents, solvents or chemicals whencleaning the unit.

ELECTRICAL INSTRUCTIONS

The supply voltage should be checked before connection to assure that proper voltage for the cabinet wiring is available. To determine correct unit voltage, please refer to the serial data plate located on an inner wall  of the unit. Verify that this information exactly matches the electrical characteristics at the installation location. NOTE: We requires that a sole use circuit be dedicated for the unit. Failure to do so voids warranty.
NOTE: The unit is designed to operate with a voltage fluctuation of 5% of the voltage indicated on the cabinet serial data plate. Burnout of the compressor due to exceeding the high or low voltage limits will automatically void the factory warranty.
Units are provided with a U.L. approved power cord and plug which is factory installed. Infrico use these types of plugs. If you do not have the right outlet have a certified electrician install the correct power source:
WARNING: Any alterations to this cord and plug could cause an electrical hazard and will void the factory warranty. Furthermore, never use an adapter plug.
WARNING: We will not warranty any units that are connected to an extension cord.

STARTUP PROCEDURE

After the cabinet has been installed, levelled, cleaned and electrically connected in accordance with this manual, it is ready to operate.
7.1 Digital temperature controller (Carel)
These units are equipped with a digital temperature controller located in the front panel.
This digital controller is fitted with a very powerful display, with 3 digits and decimal point and icons. The keypad
ensures ease of use and reliability, and allows direct access to several operation functions. KEYPAD

1. HACCP: Enter the HACCP alarm display menu (optional).
2. AUX: Deactivated in these models.
3. LIGHT: Deactivated in these models.
4. UP / CC: If pressed for more than 5 seconds, activates/deactivates continuous cycle operation.
5. ON/OFF: If pressed for more than 5 seconds, it will turn the equipment on/off.
6. PRG/MUTE: In the event of an alarm: this mutes the sound alarm (buzzer) and deactivates the alarm relay.
7. DOWN / DEF: If pressed for more than 5 seconds, it will turn manual defrosting on/off provided the evaporator temperature is lower than the final programmed defrosting temperature.
8. SET: If pressed for more than 1 second, it will display and/or confirm the set point.

DISPLAY AND ICONS

7.2 Start-up
Plug the apparatus into an electrical socket. The digital controller will display “OFF” and alternatively the cabinet temperature.
Connect the start-up ON/OFF button during more than 5 seconds.
The cabinet temperature will be displayed and “OFF” will disappear. The compressor starts up after 1 minute.
The system should run smoothly and quietly in accordance with generally accepted commercial standards. If any unusual noises are heard, turn the unit off immediately and check for any obstructions of the fans.
All cabinets must be given enough time to reach normal operating temperature before placing any food inside cabinet or pans (if equipped). Continuous opening and closing of the doors / drawers will hamper the unit’s ability to maintain optimum refrigeration performance.
NOTE: Before loading product, we recommend to run the unit empty during 24 hours. Refrigerated Back-Bar and
Merchandiser are designed to maintain an approximate temperature of 39ºF.

OPERATION

8.1 Temperature control adjustment
Setting the set point
The set point establishes the high point of the desired cabinet temperature range. This parameter is preset at the
factory and does not have to be adjusted unless the customer chooses to do so.
To display or set the set point, proceed as follows:

1. Press for more than 1 second to display the set point;
2. Increase or decrease the set point using the buttons respectively, until reaching the desired value;
3. Press again to confirm the new value.

Refrigerated Back-Bar (ERV) and Merchandiser (ERC)
The thermostat is factory set at 39ºF. The minimum temperature that can be set for the set point is 28ºF.
Re-establishing manual reset alarm
It is possible to re-establish all manual reset alarms by pressing the “PROG/MUTE” and “CONTINUOUS CYCLE” buttons at the same time for more than 5 seconds.
8.2 Defrost control
All these models are equipped with an automatic defrost system which clears the evaporator coil of any accumulated frost. Frost is accumulated on the evaporator coil during the normal operation. The defrost are time-initiated and temperature-terminated. In refrigerators, prep tables and chef bases, defrost system works by switching-off the condensing unit and switching-on the evaporator fan(s). The defrost cycle occurs automatically every four hours and is indicated by the letters “dEF” displayed on the screen. The defrost cycle should last until the temperature set for the end of the defrost cycle is reached or for a maximum of 30 minutes.
Freezer models have a hot gas defrost system. Hot gas defrost system works by routing superheated compressor discharge gas directly to the evaporator. The defrost cycle occurs automatically every three hours and is indicated by the letters “dEF” displayed on the screen. The defrost cycle should last until the temperature set for the end of the defrost cycle is reached or for a maximum of 30 minutes.
At the end of the defrost cycle, the cabinet starts with normal refrigeration operation.
Starting a Manual Defrost Cycle
In case a manual defrost is required, it is possible to activate it by pressing button for 5 seconds.
8.3 Adjusting operation parameters
There are some parameters that can be modified by the user. To access the frequent parameters, proceed as follows:
Press for more than 5 seconds (if an alarm is active, the buzzer is muted), the display shows the code of the first modifiable parameter. Then, follow the next instruction:

1. Press until reaching the parameter to be modified;
2. Press to display the associated value;
3. Increase decrease the value with the or buttons respectively, until reaching the desired value;
4. Press to temporarily save the new value and return to the display of the parameter code;

Important: To definitively save the new values of the modified parameters, press exiting the parameter setting procedure. for more than 5 seconds, thus the parameter setting procedure.
All the modifications made to the parameters, temporarily saved in the RAM, can be cancelled and “normal operation” resumed by not pressing any button for 60 seconds, thus allowing the parameter setting session to expire due to timeout.
Important: if the programming session ends by timeout, the parameters relating to the clock will not be reset, as these parameters are saved immediately when entered.
If the instrument is switched off before pressing saved will be lost. , all the modifications made to the parameters and temporarily
Adjusting the Set Point Differential (rd)
This parameter sets the number of degrees the air temp will rise above set point before the refrigeration system will cycle on.
In refrigerators and prep tables models, the set point differential is set at 7.2 which will allow the air temperature to rise 7.2 degrees above set point setting before cycling refrigeration on. In freezers, the set point differential is set at 5.4. This parameter is preset at the factory and does not have to be adjusted unless the customer chooses to do so. To set the set point differential, the parameter that should be changed is “rd” according to the previous instructions. The range of adjustment that we recommend is 3.6ºF / 10.8ºF. Low values guarantee a room temperature that deviates only slightly from the set point, but involves frequent starts and stops of the compressor.
Adjusting the Thermostat Probe Calibration (/c1)
This parameter is used to correct the temperature measured by the probe, using an offset. The value assigned to this parameter is in fact added to (positive value) or subtracted from (negative value) the temperature measured by the probe. The temperature value is corrected by the offset before checking if the reading is out-of range.
To set the thermostat probe calibration, the parameter that should be changed is “/c1. The default value is 0 which means that there is no offset to the reading of probe 1.
Adjusting the Anti-Short Cycle Delay (c1)
This parameter sets the minimum time (in minutes) between two starts of the compressor, irrespective of the temperature and the set point. Setting this parameter limits the number of starts per hour. To set the anti-short cycle delay, the parameter that should be changed is “c1” . The default value is 1minute.
Adjusting the Interval between Defrost Cycles (dl)
The defrost cycles are performed periodically at an interval equal to the value of “dl” in hours. The interval “dl” starts being counted from the end of the previous count. The duration of the defrost therefore does not affect then the interval between defrost cycles. The interval “dl” is cyclical and is also maintained when the controller is OFF. If the interval “dl” expires when the controller is OFF, when it is started again a defrost will be performed.
If “dl”=0 the defrost is never performed except for when forced from the keypad (manual defrost).
Important: To ensure regular defrosts, the interval between defrost cycles must be greater than the maximum defrost duration, plus the dripping time and post-dripping time.
Note: during defrost cycles the temperature alarms are disabled.
The parameter is “dl. The default value is 4 hours in refrigerated tables, prep tables and chef bases. In freezer, the default  value is 3 hours.
Adjusting the Maximum Defrost Duration (dP1)
This parameter determines the maximum defrost duration on the evaporator in minutes if defrost by temperature is selected.
If timed defrost has been selected, this represents the actual duration of the defrost selected. The parameter is “dP1” . The default value is 30 minutes.
Summary of parameters that can be modified by the user

8.4 Digital temperature controller (Dixell)
These units are equipped with a digital temperature controller located in the front panel.
This digital controller is fitted with a very powerful display, with 3 digits and decimal point and icons. The keypad ensures ease of use and reliability, and allows direct access to several operation functions.

Note: while in the OFF status, the light button is active
8.5 Loading product

• Before introducing food into the cabinet, it is advisable to leave it empty while in operation until it reaches the working temperature. Once this has been reached, you can proceed to load the equipment.
• When introducing food, enough space must be left between the goods to enable air circulation.
• Never allow the goods to prevent doors from closing.
• Do not exceed the maximum weight per shelf of 55 lb.
• Do not obstruct the fan with the load and assure that this never exceeds the maximum load level determined. The load must therefore always be situated underneath the fan.
• Never put hot food in the cabinet.
• Do not leave food inside the unit when it is going to remain shut down either from a power outage or fault in the equipment.
• If the cabinet is going to remain shut down for prolonged periods, try to leave it unplugged, empty, clean and with door ajar.
• Food or drinks may be well wrapped or enclosed in airtight containers to avoid odours inside the unit.

ACCESSORIES

9.1 Shelving
Installation of shelves
Back-Bar are supplied from factory with pilasters, stainless steel rails and stainless steel shelves. Shelf rails are installed by inserting them into the pilasters at the desired shelf location. Then, place shelves on the rails, making sure they are seated roperly.

MAINTENANCE, CARE AND CLEANING

10.1 Cleaning procedure
Cleaning the cabinet
To clean the cabinet, the following instruction should be followed:

• Disconnect the unit from the power supply and remove all food product from inside.
• Open all doors and allow the cabinet to reach room temperature. Remove all accessories and clean them with a baking soda or mild soap and warm water solution. Dry all of the accessories completely with a soft clean cloth.
• Once the cabinet has reach room temperature, wash the entire cabinet inside and out with a baking soda or mild soap and warm water solution. Rinse thoroughly with clear water and dry with a soft clean cloth. Failure to dry all surface completely may cause water stains. There are also stainless steel cleaners available which can restore and preserve the finish of the steels protective layer.
• Return all accessories to their initial positions and plug the unit in.
• Early signs of stainless steel breakdown can consist of small pits and cracks. If this has begun, star to apply stainless steel cleaners in order to restore the passivity of the steel.
• Many product foods have an acidic content which can attack stainless steel, such as mustard, mayonnaise, lemon juice, tomatoes and other vegetables.

NOTE: Never use steel pads, wire brushes or scrapers to clean the cabinet.
NOTE: Cleaning solutions need to be alkaline based or non-chloride cleaners. Any cleaner containing chlorides will damage the protective film of the stainless steel.

Gaskets Maintenance

• Gaskets require regular cleaning to keep their elasticity, to maintain proper sealing and to prevent mildew build up. Gasket cleaning can be done with the use of warm soapy water.
• Avoid hard cleaners and sharp tools when cleaning gaskets.
• Gaskets can easily be replaced just pulling out of the grove in the door and new gaskets can be pressed back into place.

Cleaning the condenser coil
The condenser coil, which is located directly behind the front panel, must be checked periodically. The frequency of cleaning depends on the operating environment. Air must be able to freely circulate through the condenser, so the surface of the condenser must be kept free of dirt and grease for proper system operation. Dirty condensers result in compressor failure and product loss. If the condenser coil is dirty or blocked, follow this instruction:

• Disconnect the power supply
• Remove the screws on the hinged front panel of the cabinet and open it.
• Slide out the condensing unit, and the condenser is easy accessible.
• Carefully clean dirt from the condenser using a vacuum cleaner of soft brush; never use a wire brush.
• Heavier dust build up may require compressed air to blow through the condenser coil.
• Slide the condensing unit back into position.
• Finally, replace the front panel, tighten all screws and reconnect electrical power supply.

WARNING: Never use water for this cleaning procedure as water can damage the electrical components located near or at the condenser coil.
Doors/Hinges Maintenance
Over time and with heavy use doors the hinges may become loose. If it is noticed that the door is beginning to sag, it may become necessary to tighten the screws that mount the hinge brackets to the frame of the unit.
Drain Maintenance
Each unit has a drain located inside the unit which removes the condensation from the evaporator coil and evaporates it at an external condensate pan. If you notice excessive water accumulation on the inside of the unit be sure the drain tube is connected from the evaporator housing to the condensate evaporator drain pan.
If water is collected underneath the unit you may want to check the condensate evaporator drain tube to be sure it is still located inside the drain pan.
Be sure all drain lines are free of obstructions, typically food product is found blocking drain lines causing water to back up and overflow the drain pans.
10.2 Parts and Service
WARNING: Make sure that the equipment is unplugged before cleaning or repairing it.
If the problem persists after you have carried out the indicated checks, “DO NOT MAKE ANY REPAIRS YOURSELF”. Contact our Technical Service. Always provide the cabinet model and serial number (located on the data plate, 15 digits)
NOTE: When a replacement part is required, always insist on factory authorized parts only.
