Hydraulic Connections - Toshiba QuietCo2OL Notice D'instructions

REFRIGERANT PIPING WORK
Before any work is done on the refrigeration circuit, the holding charge must be removed.
The piping used must be of copper refrigeration quality in accordance with PED 2014/68/EC
and EN12735-1.
All piping must be correctly supported and fixed and should in no case be allowed to
restrict the operation of the gas cooler unit. For the connection of piping, protect sensitive
components located around the permanent assemblies to be made.
The products added for thermal and /or acoustic insulation must be neutral with respect to
support materials.
The protection devices, piping's and accessories must be protected against unfavorable
effects from the environment.
The liquid line piping should be considered as an extension of the condensing unit receiver. A special
attention must be paid to the piping path and the thermal insulation. In case of exposure to heat source
(piping path exposed to the sun and not protected, piping path through non ventilated attic,...), The liquid
inside the piping can be vaporized and can cause an abnormal receiver pressure increase which could lead
to unit failure.
