4 SAFETY INSTRUCTIONS
To avoid any risk of accident during installation, start-up and
adjustments, the following equipment specifics must be taken
into account:
- Pressurised refrigerant circuits
- presence of refrigerant
- Presence of electrical voltage
Only experienced and qualified persons may work on such
equipment.
The recommendations and instructions in this manual and on
each drawing provided with the unit must be followed.
In the case of units with pressure equipment or components, we
recommend that you contact your professional organisation for
information on the regulations that apply to operators or owners
of pressure equipment or components. The specifications of
this equipment or components are given on the name plate
or in the regulatory documentation provided with the product.
A fire protection device is fitted as standard on the units.
IMPORTANT:
Before working on the unit, ensure the power has been
disconnected at the main disconnect switch in the unit's
electrical cabinet.
5 MACHINE COMPLIANCE
Refer to the document entitled “Declaration of conformity” supplied with your equipment.
6 WARRANTY
The warranty is effective for a period of 12 months from the date the unit is first commissioned into service provided said date
occurs within three months of the invoice date.
It is effective for a period of 15 months from the unit invoice date in all other cases.
NOTE: Refer to our general terms and conditions of sale for further information.

7 UNIT LOCATION
These units are typically used for refrigeration and are not
required to withstand earthquakes. Earthquake resistance has
therefore not been checked.
Before setting up the unit in its intended location, the installer
must check the following points:
- These units are designed to be installed and stored inside a
machine room that is sheltered from frost and the elements.
Failure to do so will incur the loss of the manufacturer's
warranty.
- The surface area of the ground or structure must be strong
enough to bear the unit's weight.
- The unit must be perfectly level.
- There must be sufficient free space around and above the
unit to allow servicing and maintenance (see dimensional
drawing provided with unit).
- The room housing the unit must comply with the requirements
of regulation EN 378-3 and other specifications applicable at
the installation site.
- The selected location must not be liable to flooding.
Provisions must be made for the drainage of defrosting water.
- Sound level:
• Our units are designed to operate quietly.
• In the installation design, you must take into account the
interior environment for radiated noise and the building type
for airborne and solid-borne noise transmission.
• To ensure vibrations transmitted by solid materials are
reduced as much as possible, it is strongly recommended
to fit anti-vibration mounts between the unit support and
frame (see the section on anti-vibration mounts), as well as
flexible couplings on the hydraulic piping.
• Have an analysis carried out by an acoustics engineer.
IMPORTANT: The ambient temperature must not exceed 50°C
during the unit's off cycles.

8 HANDLING AND POSITIONING
To raise the unit, attach the slings to the designated handling holes.
The data relating to the centre of gravity and the position of the anchorage points are given on the dimensional drawing.

The unit can be handled with a forklift truck (check the
maximum permissible load of the forklift).
In this case, it is important that the necessary precautions be
taken to avoid the unit sliding on the forks of the forklift. You
must observe the instructions given on the label affixed to the
unit. Failure to observe these instructions may result in the unit
tipping over and causing physical injury.
WARNING:
- Attach the slings only to the anchorage points intended for
this purpose and which are designated on the unit.
- Use slings with a suitable lifting capacity and follow the lifting
instructions on the drawings provided with the unit.
- Caution: the centre of gravity is not necessarily at the middle
of the unit and the forces applied to the slings are not always
identical.
- Raise and set down the unit carefully. Take care not to tilt it
by more than 15°, as this could adversely affect its operation.
- To avoid damaging the casing, use textile slings with
shackles.
- Use a frame with an adjustable centre of gravity to keep the
slings away from the top of the unit.
- Always protect the unit casing (panels, posts, front access
door) from damage during handling. Only the base frame is
designed to withstand handling.
- Safety when lifting can only be guaranteed if all these
instructions are followed.
Otherwise, there is a risk of damage to the equipment and
personal injury.

Compressor
The DYNACIAT LG, LGP and DYNACIATpower units use
hermetically sealed SCROLL compressors.
Oil
The compressor is lubricated with a polyester oil, (POE)
type 160SZ for the DYNACIATpower 700V to 1200V. This oil
will be 3MAF type (32 cSt) for DYNACIAT LG - LGP and
DYNACIATpower 1400V to 2400V.
If necessary, top up the compressors with ICI Emkarate RL 32
CF oil or Mobil EAL Arctic 22 CC oil if no 3MAF is available for
R410A models.
Refrigerant
The DYNACIAT LG, LGP 120V to 600V and DYNACIATpower
700V to 2400V operate with R410A.
The Global Warming Potential (GWP) is 2088 GWP for R410A
in compliance with norm EN378-1
Exchangers
With the DYNACIAT, the evaporators and condensers are
single-circuit brazed-plate heat exchangers.
With the DYNACIATpower, the evaporators and condensers are
double-circuit brazed-plate heat exchangers.
The evaporators are insulated with 10 mm thick polyurethane
foam. 19 mm insulation is available as an option (standard fitment
for operation with low temperature glycol water below 0 °C).
The heat transfer fluid must be filtered and internal inspections
must be carried out.
Repairs or modifications of any kind to the plate heat
exchangers are prohibited. Only replacement of the heat
exchanger with another original heat exchanger and by a
qualified technician is authorised.
If the heat exchanger is replaced, this must be noted in the
maintenance booklet.
Thermostatic expansion valve
The expansion valves have a thermostatic charge (MOP)
allowing the maximum possible evaporation pressure to be
obtained in order to protect the compressor.
Every unit is fitted with packaged hermetically-sealed
thermostatic expansion valves that are set in the factory to
maintain superheat of 5 to 7°C under all operating conditions.
Dryer
All units are fitted as standard with a dryer filter (on the
DYNACIATpower the filter unit has a replaceable element)
whose role is to keep the refrigerating circuit clean and free
of moisture. The dryer filter consists of aluminium oxide and a
molecular sieve that neutralises any acids in the refrigeration
circuit.
Liquid sight glass
Located on the liquid line just after the filter dryer, the liquid
sight glass is used to monitor the charge in the unit and to
check for moisture in the circuit. Bubbles in the sight glass
mean that the refrigerant load is insufficient or that non-
condensable gases are in the refrigeration circuit. If the sight
glass indicator paper changes colour, there is moisture in the
circuit.
Warning: Some of the sight glasses may turn yellow when the
machine is powered off as their sensitivity is affected by the
fluid temperature.
The sight glasses should return to green after the unit has
been operating for a few hours.
If the sight glasses remain yellow, there is excessive moisture
in the circuit.
A specialist intervention is required.
