Commissioning

1. Prior to electrically connect the facility, make sure that the AC
power line voltage and frequency ratings correspond to the
indications on the identification plate and the power voltage is
within a tolerance of + 10 % with respect to the rated value.
2. Specific protection is provided according to the neutral system.
3. Any on-site wiring must comply with the legal standards in
force in the country of installation (including grounding).
4. Before turning on a device, make sure that:
- the electric connections have been correctly made
- the clamping screws of the various terminals are correctly
tightened
5. Check the possible presence of locking devices of compressor
antivibration elements, and remove them, if they exist.

Operating

1. Do not use the refrigeration equipment or components for any
utilization other than that for which it is designed.
2. Comply with the special manufacturers' recommendations con-
tained in the manufacturers' operating instructions.
3. It is strictly prohibited while the device is running to remove the
guards and panelling provided by the manufacturer to protect
the user and ensure his safety.
4. When operating, surface temperatures above 60°C and /or
below 0°C may be reached. During any servicing operation,
the personnel should be extremely careful while working on the
device.
5. Profroid is not informed to real use of partly completed machi-
nes; their integrations and use must comply to Machines
Directive and recommendations of this operating instructions.
6. Results of design calculations, checks, and test reports in rela-
tion with low voltage directive are archived.

Maintenance

1. The device must be checked and inspected into service, regu-
larly, by a qualified and approved personal, following rules.
2. The device will be subject to preventive maintenance (EN 378):
- external visual inspection of device,
- checks of device during running,
- checks of device corrosion.
3. Before working on pressurized components, shut down the
facility and wait until the equipment is at the ambient (room)
temperature.
4. Before removing the guards and panelling, turn off the device.
Set it aside and make sure that no power is present.
5. Do not use piping to access on the equipment or to store
something on the equipment.
6. The replacement of a safety valve must be made by the same
brand of the original one.
If there is modification of type and /or brand, then the professio-
nal in charge of the replacement will do a calculation sheet fol-
lowing EN 13136 and /or ask Profroid some elements.
7. Handle regularly the device valves in view to avoid theirs
blocking on.
8. If a personal in charge of maintenance closed a blocked valve,
this personal will must avoid the possible increase of pressure
in the part of device which is isolated.
9. The periodic technical checks must be made following frequen-
cies determined by standards, sound engineering practice, end
user and installer.
10. Report periodic checks and analyze the data. In case of abnor-
malities or inconsistencies, determine the cause and correct it.

11. In case of hanged units (evaporator as an example), it is
necessary to define an exclusion zone on the ground, to avoid
the presence of persona under the equipment.
12. It is important to ensure that the hinge mechanisms of moving
parts are operational before all manipulations (drain pan, door,
fans mounted on hinges,...).
13. In general, when opening any moving parts it is necessary to
accompany them or slow their opening speed to avoid casing
deformations.
14. Lockable fan switch aren't safety accessories.
15. Manipulate the drain pan cautiously.

Recycling

Before disassembling all or part of a device, make sure that the
power supply has been switched off.
Recover for recycling by means of appropriate tools the refrigerant
present in the unit or in the area of intervention after isolation of it.
Collect all used oil and deposit it in the appropriate recycling cen-
ters. Remember to drain the oil separator. Eliminate all or part of
the device in a suitable recycling center.

Reach

Concerning the DANFOSS components (KVP, KVL, KVR, KVD),
avoid any contact between the skin and the O‐ring. Concerning the
DANFOSS components (ETS, KVS, SGN, SGP), avoid any contact
between the skin and the paper. Avoid to breathe dust that might
come from the paper. Recycle the paper as hazardous waste.
