Figure 1 - Main units of the display case
Figure 2 – Monte S(SH), Monte M(MH), Monte L(LH) display cases

www.combisteel.com
1.3.2 Display case operation
The useful volume of the refrigerated display case is cooled based on the principle of heat transfer from the
useful volume of the display case to the environment. The heat from the useful volume is carried into the
evaporator, compressor transfers it by the refrigerant to the condenser, and then it is removed to the
environment.
The refrigerated display case operation is the operation of its refrigeration system controlled by an electronic
regulator (controller). The controller's temperature sensor reads the air temperature in the useful volume of the
display case, when the set temperature is exceeded, the solenoid valve opens and the refrigerant is supplied to
the evaporator. When the desired temperature is reached in the useful volume of the dis-play case, the controller
switches off and closes the solenoid valve, thereby cutting off the refrigerant supply to the evaporator. The
evaporator defrosting time and frequency are determined by the controller settings.
The control panel consists of:
1. Electronic controller.
2. Illuminated key switch.
Figure 3 - Control panel
The electronic controller (1) is used to automatically maintain the temperature in the refrigerated space and
control the air cooler defrosting process. See the Electronic Controller User's Manual in Appendix D to the
Manual. The factory setting ensures optimal operation of the product. The controller can be readjusted by the
service personnel only. The switch (2) is used to turn the lighting on and off. The interior of open display cases is
insulated by an air curtain (an invisible air flow barrier between the upper honeycomb and the lower suction
panel).
Warning: Do not block the cooled air supply for the air curtain (by goods, labels, price tags, etc.)
To reduce energy consumption during off-hours, the display cases can be optionally equipped with night covers
(Fig.4). In order to prevent the refrigeration loss, as well as to ensure perfect sanitary conditions, the display case
can be closed with a night cover, available on request as an option, for the night time.
Figure 4 - Night cover

www.combisteel.com
Warning: The night cover requires a careful handling. The night cover should be raised/lowered
smoothly, without any jerks and distortions, using a special handle, until the cover fixation. This is necessary to
avoid damage to the mechanism and wear of the night cover material.
Warning: If the customers do not fulfil the above requirements, the warranty for the night cover is not
provided!
See Appendix E for the night cover installation instructions.

3 Proper use
3.1 General guidelines
The Manual provides information necessary for the proper operation and maintenance of the display cases
during their intended use. The display case service life and safety in operation depend on observance of the
operating rules.
3.2 Safety measures
The display cases meet the safety requirements of Technical Regulations of the Customs Union: TR CU 004/2011
"On safety of low-voltage equipment", TR CU 010/2011 "On safety of machinery and equipment", TR CU
020/2011 "Electromagnetic compatibility of technical means".
The display cases belong to I class of human protection against electric shock according to GOST IEC 60335-1.

Warning: Observe the following safety rules when working with the display cases:
-check the cable before connecting the display cases to the mains and make sure it is working properly;
-connect the mains plug to a grounded socket only;
-the power cord may only be replaced by the qualified personnel authorized to this type of works;
-in case of any faults in the electrics (wire insulation fault, ground wire breakage, etc.), immediately
disconnect the display case from the mains and call an electrician.
-connect the showcases to the supply mains (Fig.4) via an automatic circuit breaker of combined
(thermal and electromagnetic) protection with a rated current value of:

QF, QF1 – automatic circuit breakers;
XP – 3 pole plug and socket EURO connector with grounding terminal.
For the wiring diagram see Appendix B.
Warning: Do not operate equipment with a missing or faulty ground connection.
Warning: Before dismantling and depressurization of refrigeration system components, drain the
refrigerant into a special container, avoiding its leakage into the atmosphere.
Precaution: The display cases are not intended for use by persons (including children) with reduced physical or
mental capabilities, or lack of experience or knowledge, unless they are supervised or instructed regarding the
product use by a person responsible for their safety. Children should be supervised to prevent playing with the
product. In case of non-compliance with these safety measures, the manufacturer shall not be liable for the
safety.
3.3 Display case installation.
Warning: When the display case is delivered, check the packaging for damages. If there are any defects,
make a claim to the transport company. The display cases should be transported in a vertical position only.
Carefully unpack the display case, taking all necessary precautions to avoid mechanical damage to the external
front surfaces of the product. Remove the components from the interior. Read the datasheet. Check the delivery
package.
Remove the display case from the wooden pallet by unscrewing the fixing bolts.
Indoors, the product can only be moved in accordance with the handling circuit on the nameplate.
Tilt the display case 15° back and screw the front feet, then tilt it forward and screw the rear feet.
Set the display case level to a stable horizontal position using height-adjustable feet.
When installing display cases at the operating site, observe the following conditions:
-the ambient air temperature should not exceed 25°C, because at temperatures above 25°C and relative
humidity of more than 60%, the technical characteristics specified in p. 1.1 are not guaranteed;
-provide an air conditioning system in the room to maintain normal operating conditions, because the
common ventilation will increase the humidity, which will reduce the operational reliability;
- do not install showcases near doors or in halls with artificial air flows to avoid air flows of more than
0.2 m/sec, humidifying the air;
-install the display case at least 1 m away from the heat source, and sun-warmed walls and ceilings;
-keep the clearance of at least 60 mm between the display case and the wall.
In case of failure to observe the above conditions, the display cases will not meet their performance
characteristics and the power consumption will increase.
Before using the display cases: carefully remove the protective film from the outer and inner panel surfaces;
wash them with warm water and neutral detergent; rinse; dry. When washing, prevent moisture ingress in
electrical items.

INSTRUCTION
EKC202B, EKC302B CONTROLLER SETTINGS ADJUSTMENT
1. PURPOSE
The controller as part of the refrigeration equipment is designed to control its operation and provides the
following:
maintaining the temperature in the refrigerated space within the required range;
automatic defrost of the air cooler;
compressor protection.
The front panel of the controller is shown in Fig. 1.
Fig. 1.
1, 2, 3 - programming keys; 4 - display; 5 "minus" signal; 6 air cooler fan activation indicator (illuminated);
7 defrosting indicator (illuminated); 8 - refrigeration indicator (illuminated).
2. BRIEF DESCRIPTION
The front panel of the controller contains three programming keys (1), (2), (3) and a display that shows three
numbers or letters (4), a minus sign (5), an air cooler fan activation signal (6), a defrosting signal (7), and a
refrigeration signal (8).
The controller maintains the interior temperature by periodical starting and stopping the compressor according
to a signal received from the sensor installed in the air cooler. If the interior temperature exceeds the set value
(the first line in Table 1), then the controller activates the compressor. After reaching the specified interior
temperature, the controller stops the compressor. When the compressor is disabled, the interior temperature
increases due to heat flows, and when a value equal to the sum of the previous set value (the first line in Table
1) and the value "r01" is reached, the controller activates the com-pressor.
When products are cooled (the compressor is running), the display (4) shows the interior temperature value and
the refrigeration signal (8). When the compressor is disabled, the refrigeration signal (8) is not displayed.
To see the temperature on S5 evaporator sensor, press briefly the key (2), and to activate the forced defrosting,
press and hold the key (2) for 5 seconds.
3. TEMPERATURE SETTING ADJUSTMENT
Set value adjustment procedure:
press the key (3) until the temperature set value appears on the display;
select the desired value by pressing the keys (1) or (2) ;
press the key (3) to record the value.
