1 - INTRODUCTION
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
NFE 29795.
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. When
cylinders are empty, evacuate the remaining gas pressure,
and move the cylinders to a place designated for their
recovery. Do not incinerate them.
ATTENTION: Only use refrigerant R134a, in accordance with
700 AHRI (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.
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 purge
the unit water circuit, before working on the components
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 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.
