MANUAL
010 - GENERAL INFORMATION/TABLE OF CONTENTS
This manual has been compiled in a simple and easy-to-read manner so our units can be installed, set
up and serviced correctly. Please read its contents carefully and keep it near the machine at all
times.
The following points are of capital importance:
•The equipment must be installed, tested and serviced by skilled and legally qualified personnel.
•Local safety regulations applicable at the time of installation must be observed.
•The refrigerating equipment must only ever be used for the purpose for which it was designed. Uses
other than those specified shall in no way be binding for the Manufacturer.
•Any packaging components included (plastic bags, polystyrene, wood, etc.) represent a potential
hazard and must be kept out of the reach of children. Sort them out and dispose of them according
to local applicable regulations.
•Power supply specifications must comply with the details shown on the serial plate of the machine.
•In the event of failure or of malfunction, always switch off the machine.
•Modifications to the power system or unauthorized alterations in general, which are not
contemplated in this manual, shall invalidate the warranty.
•To service or repair the machine, always contact an authorized Costan after-sales service center and
ask for original spare parts. Failure to do so could jeopardize machine and operator safety.
THE MANUFACTURER DISCLAIMS ALL LIABILITY FOR DIRECT OR INDIRECT
DAMAGE TO PROPERTY AS WELL AS FOR ANY PERSONAL INJURY ARISING FROM

020 – DESCRIPTION / TECHNICAL DETAILS
General
Eptagloo refrigerating units are available in a three and a four-compressor version, featuring parallel-
connected semi-hermetic compressors by Bitzer (“Octagon” series) or Frascold. These compressor
packs are appropriate for positive and negative-temperature applications using refrigerant gas R404a,
they are meant to be installed indoors in suitable plant rooms or either outdoors when fitted out the
appropriate weather protective enclosure.
The range was designed and constructed to the applicable laws and EU Directives. This equipment is
available in a baseline version for indoor installation, including the components strictly required to
guarantee total reliability and correct performance of the machine, in compliance with Epta’s
renowned quality standards: On-board electrical panel for compressor control and regulation,
compressors installed on a stout galvanized and painted metal-sheet undercarriage, suction header
designed to ensure the return of oil to the compressors, suction filter, filter dryer on the liquid line with
liquid and humidity indicator, liquid receiver vessel. High customizability results from the possibility
to choose - as an option from the baseline version up – among as many as five different types of
electronic controllers and a switchboard that can be fitted with overcurrent protection or overcurrent
plus residual current protection. Installation options (either for indoor installation in plant rooms or
outdoors) can be associated to an enclosure soundproofing option. Accessories range from the sole
inspectable oil-separator option, directly discharging into the suction line, to the complete oil-return
option including separator, oil reservoir, distribution header and float regulators. Pulse dampers
(mufflers) are fitted to every single compressor, as well as external pressure-gauge connections,
glycerin-dip high and low pressure gauges, compressor power-factor correction, liquid subcooling for
low-temperature systems (when associated to a medium-temperature unit).
Main features (standard version)
•Power supply panel constructed to EN 60204-1, integrated in the equipment and pre-wired. The
electrical panel is test-run at the factory before the equipment is released. Master circuit-breaking
handle on the outside.
•Controller unit pull-out box, with access door from outside the equipment. Controller type to be
selected among five different alternatives.
•Suction header also acting as anti-liquid bottle; insulation of the entire suction line, of circuit
suction stretches (header – compressor) and of the suction filters.
•Replaceable mechanical-cartridge filter on the suction line, upstream of the suction header (two
filters for four-compressor systems).
•On-board liquid receiver complying with the requirements of EU Directive 97/23, capacity 40L.
(for 3 compressors ) and 60L. (for 4 compressors).
•Safety valve complying with EU Directive 97/23/EC to protect the liquid receiver against pressure
rise caused by external heat (fire)
•High-capacity anti-acid drier filter with replaceable core on the liquid line, with liquid and moisture
indicator.
•Pressure-switch and probe panel including:
Two high-pressure switches (manual-reset for system safety) to protect from high pressure
caused by mismaneuvering or other causes. When test-run as per operational instruction
QOP019110A, correct tripping of safety pressure-switches was simulated and verified
One high pressure switch for each compressor (compressor safety)
