PREPARING THE DEVICE FOR START-UP
The unit must be properly installed and located according to the installation instructions before it is used
Installation requirements
- Always use a dedicated circuit with the amperage stated on the unit.
- Plug into an outlet designed for the plug
- Do not overload the circuit.
- Do not use extension cords.
- Never use adapters.
- Never plug in more than one unit per electric circuit.
- If in doubt, call an electrician.
IGLOO will not warranty any equipment that is connected to an extension cord or an adapter plug. The equipment may be turned on after confirmation of the fire protection efficiency with the results of measures performed according to binding regulations!
Unit Location
- Install the unit on a strong and leveled surface.
- To ensure proper operation the unit must be leveled from front to back and left to right.
- The unit may malfunction if improperly leveled.
- Be sure there is sufficient ventilation around the entire unit.
- Select a location away from heat and moisture-generating equipment.
- Avoid installation in a high ambient or humid location.
- High ambient temperatures will cause the compressor to overwork.
- Humidity may cause rust, and condensation around glass or stainless steel and decrease the efficiency of the unit.
Connection and start-up
- Remove cardboard angles and protective foil.
- Place the unit on an even and hard base. Then level the unit with the leveling legs.
A – Screw the leg in nuts
After installation of the equipment at the destination location it should be left to rest for at least 2 hours before turning it on (for devices with builtͲin compressors) to set the level of refrigerant to prevent problems with the start-up.

UNIT START-UP
The Temperature of the cooled space and aggregate operating cycle may fluctuate. This depends on numerous factors, such as the amount and temperature of products placed in the device and the temperature of the surroundings. The equipment should be placed in a dry and wellͲventilated area, ensuring proper air exchange (distance between the wall and the equipment– min. 10cm), out of sunlight, kept far from heat sources and devices enforcing air flow (ceiling and portable ventilators, blowͲin heaters). The equipment functions properly in a room, where the temperature falls within the appropriate climatic class. The operation of the equipment may worsen when operates outside the stated temperature range
Remarks and indications
- The display case has to be properly leveled, which will prevent noisy corking of the equipment and shall ensure proper water (condensate) outflow during defrosting
- After transporting the equipment, wait about 2 hours before starting up the unit.
- To ensure proper conditions for the stored products, do not load the shelves completely. Ensure an even load of shelves and not exceed the maximum load.
- The first filling of shelves should be performed after the unit has reached the desired cooling temperature. This principle should also be observed after a long pause in the operation.
- Do not block any ventilation holes, which would hamper the circulation of the cooled air. It is also necessary to ensure proper airflow around the equipment.
- Do not use electric devices inside the product-storing chamber.
- Avoid unnecessary opening of the doors and leaving them open for a longer period.
Temperature regulation
The thermostat is to obtain the set temperature within the equipment and maintain it within the determined temperature ranges. The manufacturer enters all settings of temperature regulators required for the normal functioning of the equipment. Before primary actuation, the user should control and possibly set the required temperature inside the equipment on the control panel. Digital display – displays the current temperature inside the equipment. It is forbidden to interfere with the systemic parameters of the thermostat, as this can lead to serious consequences, including damage to the cooling unit!

MODIFYING THE PARAMETERS
Parameter navigation
The operating parameters, modifiable using the keypad, are divided into two types: frequent (type F) and configuration (type C). Access to the latter is protected by a password (default= 22) to prevent accidental or unauthorized modifications.
Accessing the Type F parameters:
- Press the SET button for more than 3 s (if there are active alarms, mute the buzzers). The display shows the parameter code ‘PS’ (password);
- Use the UP and DOWN buttons to scroll the parameters. The LED corresponding to the category of parameters will be on;
- Press SET to display the value associated with the parameter
- Increase or decrease the value using the UP or DOWN buttons respectively;
- Press SET to temporarily save the new value and display the parameter again;
- Press the SET button for more than 3 s to permanently save the parameters and exit the parameter setting procedure
