2. SAFETY
2.1. Dangers due to misuse
•Only start up and operate the refrigeration equipment once it
has been properly set up and installed and has no obvious defects.
•Do not make any technical changes to the refrigeration
equipment.
•Do not store any explosive substances in the refrigeration
equipment, such as aerosol containers with flammable propellant
gas.
•Do not make any technical changes to the refrigeration equipment.

11
2.2. Safety guidelines of refrigeration equipment operating with
propane (R290) refrigerant
Refrigerant R290 (propane gas) is
classified as a refrigerant of safety group A3. Based on the refrigerant commonly
used in commercial systems, the system design and risk analysis are in accordance
with explosion protection regulations (defined by standard EN 378-1 or EN IEC
60335-2-89).
Safety guidelines:
•Keep ignition sources away (heat, sparks, open flames, hot surfaces).
•Use a damp cloth or sponge to clean and remove condensation water. Keep dry
materials from electrical parts to avoid electrical shock.
•Before turning on the refrigeration equipment, fill the drain with approx. 2 litres
of water.
•It is prohibited to cover any ventilation openings of the unit. A safe minimum
distance must be kept (between units) to ensure sufficient air access.
•Do not use any mechanical devices or other means (e.g., ice scrapers) to
accelerate the defrosting.
•Do not use steam or high-pressure cleaners for basic cleaning.
•Only install the units in well-ventilated rooms.
•Do not install the units in cellars or lowered rooms.
•Do not damage the refrigerant circuit.
•Do not expose the unit to temperatures above 55°C during transportation and
storage.
•Avoid transmitting pulsations and vibrations to the unit.
•Do not allow external forces to act on the unit, e.g., careless handling with a
forklift or floor cleaning machine.
•Do not crush or bend pipes.
•Only qualified maintenance personnel may carry out work on the refrigerant
circuit.
•Only open the refrigerant circuit and remove the refrigerant in well-ventilated
rooms outside store business hours (when customers are not present) or
outdoors.
•Disconnect the unit before all maintenance, service, or repair work.
•Disposal of the unit must be performed following Waste & Disposal-Recycling
Regulation requirements.
Failure to comply with safety requirements could lead to potential health and safety
risks.

2.3. Safety guidelines of refrigeration equipment operating in
Hydroloop Glycol system
Refrigeration equipment suited with a Hydroloop Glycol system
comes with flexible stainless steel ¾” female connections on the
pipelines.
Safety guidelines:
•It is recommended to use propylene glycol.
•The pressure of the glycol system should not exceed the designated
pressure of 6 bars.
•For the average climate temperature, we recommend 40 vol. %
concentrate.
•Glycol operating temperatures should not exceed 150 оC (boiling point).

2.4. Material damage during a prolonged shutdown
•Operate the unit in a stable operating position (horizontal alignment).
•Operate the unit only on the designated leveling legs.
•Read the installation notes if needed.
•Do not operate the unit above the climate class specified on the technical data
sticker.
•Check that the unit is in proper condition. Any damage must be repaired
immediately.
•In the event of a power failure, stored products must be inspected by the
operating company (temperature check).

13
•Check the area in which the products are placed for foreign objects. Immediately
remove incorrectly stored products.
•Do not set up or store the unit outdoors. To ensure good air circulation, maintain
a minimum distance to the surrounding walls and other units.
•Do not attach stickers or films to glass surfaces.
•Do not operate the unit if there is any glass damage (cracks, breaks).
2.5. Personal protective equipment
Use hand protection:
•Protection from heavy equipment parts during transport,
unpacking, installation, and disposal.
•Protection from sharp edges when unpacking and during setup
and installation.
•Protection from contact with liquid in the event of leakage in the refrigerant
circuit.
•Protection from low temperature during loading and cleaning.
•For removing glass parts and splinters in case of glass breakage.
Use eye protection:
•Protection from contact with liquid in the event of leakage in the refrigerant
circuit.
Wear protective clothing:
•Wear appropriate clothing (cold protection) when loading the unit with products.
2.6. Electrical voltage
Only qualified staff may carry out work on the electrical system. In
the event of fault messages or damage to the refrigeration
equipment, contact the maintenance service.
Electrical safety guidelines:
•Do not connect damaged refrigeration equipment or damaged parts (such as
connecting cables) to the power supply.
•Check to ensure safety devices are correctly installed and working.
•Do not remove protective devices and covers attached to the unit.
•Note the following before connecting to the power supply:
oApplicable local electrical safety regulations.
oApplicable standards and safety instructions.

14
oThe power supply voltage and frequency must match the specifications on
the technical data sticker.
•Only trained operating personnel may disconnect the unit.
•Observe the following safety rules if the unit is damaged during operation or
before maintenance:
oDisconnect the unit (switch off all sources of electrical power).
oSecure the unit in such a way that it cannot be connected to the power
supply, and mark it with a safety sign.
•Only qualified staff may replace damaged parts (e.g., connecting cables, lights)
•Do not use extension cords or multiple socket strips.
•Do not use steam or high-pressure cleaners for basic cleaning.
•Do not damage concealed electrical parts. The operator must not drill into the
unit or carry out any other work on it.
2.7. Refrigerant circuit
Only qualified staff may carry out work on the refrigerant circuit. In the event of fault
messages or damage to the unit, contact the maintenance service.
2.8. Improper installation of hooked shelves
There is a risk of injury due to falling of hooked shelves holding products.
The shelf brackets must snap completely into the openings provided when being
attached.
2.9. Opening/closing the doors
Hand or other body parts may become caught in the door hinge or on the handle.
•When opening/closing the doors, do not reach into the opening gap, especially
on the hinge side.
•Look out for other people when opening/closing the doors.
2.10. Recommended working conditions and ambient temperature
The refrigeration equipment is to be operated under suitable ambient
conditions (climate class 3):
•Ambient temperature must not fall below +16°C and not exceed +25°C
(improper temperature can affect the operation of the refrigeration equipment).

15
•Relative humidity should not exceed 60% (excess humidity can affect the dew
point parameters).

circulation of the open unit).
•It is forbidden to exceed the maximum allowable loading of the unit shelves.
•Recommended arrangement of the shelves is specified in the main layout.
•It is forbidden to cover air circulation channels (the placement of goods should
be logical and consistent).
2.11. Purpose of use
JUPITER is intended to be used for the presentation of chilled packaged products. It
is not intended for storing products without packaging, such as vegetables. For non-
packaged foods, the evaporator on the unit should be chosen with a special coating
suited for such product storage. JUPITER provides an average operating temperature
(0...+10°C) in the inner space of the unit.
It is forbidden to load the unit with warm goods (temperature of goods lower or
higher than the JUPITER operating temperature).
The recommended temperature for loaded goods is specified by the standard DIN
10508. The requirements for the temperatures of loaded goods are provided below:
≤+10 оC
Fruits, vegetables, butter, cheese, and cheese products
≤+8 оC
Pasteurized products, sour milk
≤+7 оC
Milk and dairy products, delicacies, ready-made food, snacks,
sandwiches, green salad, game, salad with mayonnaise sauce, cooked
meat products, eggs and their products, sauces
≤+4 оC
Household poultry, minced meat, and products, rabbit meat, wild
hare meat
≤+3 оC
By-products
≤+2 оC
Pre-packed minced meat and fresh fish (on ice)
The manufacturer is not liable for any damages caused by the unintended purpose
use of JUPITER and is exempted from warranty obligations.
3. MAXIMUM LOAD
JUPITER is equipped with shelves with a maximum allowable load, specified in the
main layout sticker (Fig. 19.). The sticker is attached to the right corner of the unit’s
inner ceiling. It is forbidden to exceed the indicated maximum loads.
