Technical information
7
pressure gauge, two air bleed valves, filling valve and drain
valve. Also includes a mesh filter for the water circuit. This
filter is supplied loose for installation at the most convenient
point.
Flow switch
Assures sufficient water flow when the unit is in operation.
Protecting grids
To protect the coils from possible impacts. Made of steel
rods and painted with oven baked polymerized white enamel
(RAL9001).
Accessories and options
Unit without hydro kit
Includes the elements described in the previously mentioned
specifications, less the hydro kit (pack). The water circuit
includes an air bleed valve. Connections are ready for field
installation.
Two pumps
Accessory available with models 50 to 100 with hydro kit.
The second pump becomes operative when the magneto-
thermal protector of the first pump is activated (models 50,
60 and 80), or through the controller program (models 100,
120 and 150).
Water filter
Supplied as a standard element on units including the hydro
kit (pack). Stainless steel mesh with 1 mm. diameter perfora-
tions.
Optional on units not including the hydro kit.
The warrantee of the unit will not be valid if a water filter has
not been installed.
Remote control unit
Wall-mounted remote control unit with keyboard for cool/heat
and ON/OFF functions. Includes power supply, alarm and
cool/heat LEDs. Maximum cable length: 50 m.
Remote terminal
For total access and control of the system by means of
the display and buttons. Allows selecting cool, heat and off
functions. Can also modify operating parameters and moni-
tor the system. 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 noise level units
Include anti-noise covers mounted on the compressors and
sound isolating plates, covering the compressor chamber.
Static starter
For smooth start of the motor. Specially designed for Scroll
compressors (maximum outdoor temperature: 50°C).
Antivibratory supports
Whenever necessary to reduce vibrations and noise produced
by the unit to a maximum, a set of steel spring antivibratory
supports can be used. These should be installed between
the chassis support of the unit and the base or floor where
same is to sit.
This base must be solid and dimensioned in accordance with
the load to be supported.
The antivibratory support accessory for models YLCA/YLHA
40, 50 and 60 includes 4 units, whereas for models YLCA/
YLHA 80, 100, 120 and 150 includes 6.
These spring supports should be distributed and fastened
in the drilled holes at the base of the chiller, the location of
which is detailed in the General Dimensions section.
