tem. Can be installed at a maximum distance of 1040 m.
BMS connections
By means of a serial board, it is possible to connect the
system to a standard RS485 monitoring network.
Low ambient temperature kit (YLCA 5 to 15)
Includes a pressure transducer for controlling condensing
pressure at low ambient temperature (-18°C).
Standard on models YLCA 20 & 27, and YLHA PLUS 5-27.
High pressure fans
Buffer tank
With a backup heater installed.
Antivibratory supports
Whenever necessary to reduce to a maximum vibrations
and noise caused by the unit, you can use a set of caoutch
antivibratory supports, that should be installed between the
supporting chassis of the unit and the base or floor on which
same should be set. This base should be solid and dimen-
sioned in accordance with the weight to be supported. To
fasten the supports to the base of the chassis, 8/10Ma screws
are used. The antivibratory supports accessory includes 4
parts. These supports should be distributed amongst and
fastened in the drilled holes in the base, the location of which
is detailed in the General Dimensions section.
