Do not unweld or flamecut the refrigerant lines or any
refrigerant circuit component until all refrigerant (liquid and
vapour) as well as the oil have been removed from unit.
Traces of vapour should be displaced with dry nitrogen.
Refrigerant in contact with an open flame produces toxic
gases.
The necessary protection equipment must be available, and
appropriate fire extinguishers for the system and the
refrigerant type used must be within easy reach.
Do not siphon refrigerant.
The accidental releases of the refrigerant, due to small leaks
or significant discharges following the rupture of a pipe or
an unexpected release from a safety valve, can cause
frostbites and burns to personnel exposed. Do not ignore
such injuries. Installers, owners and especially service
engineers for these units must:
-
Seek medical attention before treating such injuries.
-
Have access to a first-aid kit, especially for treating eye
injuries.
We recommend to apply standard EN 378-3 Annex 3.
Avoid spilling liquid refrigerant on skin or splashing it into
the eyes. Use safety goggles and safety gloves. Wash any
spills from the skin with soap and water. If liquid refrigerant
enters the eyes, immediately and abundantly flush the eyes
with water and consult a doctor.
Never apply an open flame or live steam to a refrigerant
container. Dangerous overpressure can result. If it is
necessary to heat refrigerant, use only warm water.
During refrigerant removal and storage operations follow
applicable regulations. These regulations, permitting
conditioning and recovery of halogenated hydrocarbons
under optimum quality conditions for the products and
optimum safety conditions for people, property and the
environment are described in standard NF E29-795.
Any refrigerant transfer and recovery operations must be
carried out using a transfer unit. 3/8” SAE connectors on
the liquid, suction and discharge lines are available for all
units for connection to the transfer station. The units must
never be modified to add refrigerant and oil charging,
removal and purging devices. All these devices are provided
with the units. Please refer to the certified dimensional
drawings for the units.
Do not re-use disposable (non-returnable) cylinders or
attempt to refill them. It is dangerous and illegal. When
cylinders are empty, evacuate the remaining gas pressure,
and move the cylinders to a place designated for their
recovery. Do not incinerate.
Do not attempt to remove refrigerant circuit components or
fittings, while the machine is under pressure or while it is
running. Be sure pressure is at 0 kPa and that the unit has
been shut down and de-energised before removing
components or opening a circuit. If the refrigerant circuit is
opened for repair, all circuit openings must be plugged if
the repair takes longer than 30 minutes, in order to prevent
humidity from contaminating the contents of the circuit,
especially the oil. If the work is expected to take longer,
charge the circuit with nitrogen.
Do not attempt to repair or recondition any safety devices
when corrosion or build-up of foreign material (rust, dirt,
scale, etc.) is found within the valve body or mechanism. If
necessary, replace the device. Do not install relief valves in
series or backwards.
No part of the unit must be used as a walk-way, rack
or support. The refrigerant lines can break under
the weight and release refrigerant, causing personal
injury.
Do not climb on a machine. Use a platform, or staging to
work at higher levels.
Use mechanical lifting equipment (crane, hoist, winch, etc.)
to lift or move heavy components. For lighter components,
use lifting equipment when there is a risk of slipping or
losing your balance.
Use only original replacement parts for any repair or
component replacement. Consult the list of replacement
parts that corresponds to the specification of the original
equipment.
Do not drain water circuits containing industrial brines,
without informing the technical service department at the
installation site or a competent body first.
Close the entering and leaving water shutoff valves and
purge the unit water circuit, before working on the
components installed on the circuit (screen filter, pump,
water flow switch, etc.).
Periodically inspect all valves, fittings and pipes of the
refrigerant and hydraulic circuits to ensure that they do not
show any corrosion or any signs of leaks.
It is recommended to wear ear defenders, when working
near the unit and the unit is in operation.
1.5 - Measures, provisions, procedures
against emergencies
When the machine is subjected to heat or fire, a device prevents
explosion by releasing the refrigerant (via the relief valve). This
fluid can be decomposed into toxic waste when subjected to
flame:
-
Stay away from the unit.
-
Set up warnings and recommendations for personnel in
charge to stop the fire.
-
Fire extinguishers appropriate to the system and the
refrigerant type must be easily accessible.
