Do not siphon refrigerant.
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.
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 relief 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 or ISO-
5149.
Never apply an open flame or live steam to a refrigerant
container. Dangerous overpressure can result.
During refrigerant removal and storage operations follow
applicable regulations. These regulations, permitting condi-
tioning 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. A 3/8” SAE connector on
the manual liquid line valve is supplied with 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. Proper
refrigerant cylinders designated and marked for
R1234ze(E) should be used. When cylinders are empty,
evacuate the remaining gas pressure, and move the
cylinders to a place designated for their recovery. Do not
incinerate.
ATTENTION: Only use refrigerant R1234ze(E), in
accordance with AHRI 700-2014 (Air conditioning,
Heating and Refrigeration Institute). The use of any other
refrigerant may expose users and operators to unexpected
risks.
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.
When the refrigerant circuit is opened for repair, it is
mandatory to plug all openings of the circuit if the repair
exceeds 30 minutes; this is to avoid moisture absorbed in
the circuit, especially in the oil. If the scheduled
intervention is longer, the circuit must be charged 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.
ATTENTION: No part of the unit must be used as a walk-
way, rack or support. Periodically check and repair or if
necessary replace any component or piping that shows
signs of damage.
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
drain the unit water circuit, before working on the compo-
nents installed on the circuit (screen filter, pump, water
flow switch, etc.).
Do not loosen the water box bolts until the water boxes
have been completely drained.
Periodically inspect all valves, fittings and pipes of the
refrigerant and hydronic 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.
