10 --- Appendix

10.1 --- Check the unit after the installation

The following list includes the checks to carry out to
verify that Hisp is intact after the installation.
IMPORTANT: EVERY UNIT IS TESTED IN OUR
PLANTS BEFORE DELIVERY.
A) STATIC CHECK
A.1) Evaporating unit SE
A.1.a) Sight check that the panels and rivets
are intact and well fixed.
A.1.b) Check that a condensate drain, with a
wide--- bended trap, for every machine
is available.
A.1.c) Check that the (optional) Freecooling
air intake ducts (rigid or flexible) and
the rainproof external grille, with me-
tallic prefilter (optional) are available
and fixed.
A.1.d) Check that the overpressure damper
for the outlet of the Freecooling air is
available and functions correctly (the
fins are mobile), together with the ex-
ternal rainproof grille. (Freecooling is
optional)
A.1.e) Check that the unit is fixed firmly to
the ceiling or to the wall, and that any
fastening devices passing along the
walls of the room to be conditioned are
sealed.
A.1.f) Put the electrical board of the room in
the " OFF"position.
A.1.g) Remove the lower inspection panels to
gain access to the inside of the evapo-
rating unit.
A.1.h) Gain access to the electrical board and
put the QS1 mains supply switch in the
" 0"position.
A.1.i) Check that the electrical board is free
from foreign bodies.
A.1.l) Check that the supply cables and the
Bus cable between Microface and re-
mote display are correctly connected.
A.1.m) Check the fastening and the polarity of
the emergency supply (batteries)
cables to the inverter. If in doubt, read
the wiring diagram. CAUTION: do not
alter the adjustment of the potentiom-
eters in the inverter board.
A.1.n) Check the fastening of cables, elec-
tronic components and fuses.
A.1.o) Check the evaporating fan by turning it
manually: it must be free to rotate with-
out any abnormal noise. The shaft
must be in line.
A.1.p) Check the correct position of the air fil-
ter.
A.1.q) Check that the Freecooling damper (if
installed) is intact and fastened.
A.1.r) Check that the delivery fins are ori-
ented, depending on your needs.
A.1.s) Check that the (optional) electric heat-
ers are correctly placed in the air flow,
and that they do not touch the condi-
tioner' s walls or other components.
English
A.2) SC motor condensing unit
A.2.a) Remove the front and side panels to
gain access to the refrigerating circuit
(when the weather conditions allow it:
prevent water from entering into the
electrical board and the compressor
compartment).
A.2.b) Check that the refrigerating circuit is
intact and that there are no oil stains in
the compressor compartment and
along the ducts.
A.2.c) Check the evaporating fan by turning it
by means of a screwdriver: it must be
free to rotate without any abnormal
noise.
A.2.d) Check that the electrical board is free
from foreign bodies, the correct con-
nection to the evaporating unit and
that all electrical connections are tight-
ened.
The unit is ready for the dynamic check.
B) DYNAMIC CHECK
B.1) Close the inspection panels of the evaporating
unit, with the exception of the panel letting into
the electrical board.
B.2) Check the ground connection.
B.3) Put the electrical board of the room in the " ON"
position.
B.4) Gain access to the electrical board of the evapo-
rating unit and put the QS1 mains supply switch
in the " 1"position.
B.5) Check the voltage at the main supply cables.
B.6) Check the voltage at the emergency supply
cables.
B.7) Set the required system configuration by means
of the Microface (or Hiromatic) control display,
such as set point, network (by assigning an iden-
tification number to every unit), parameter
sharing, stand--- by, Freecooling (if installed)
differentials and so on.
B.8) Start up the machine and measure the current
absorbed by the evaporating fan only.
B.9) Start up the compressor (if necessary force the
system via the control) and wait until the system
is stable. Measure the absorbed current, with
both fan and compressor operating.
B.10) Check all these values by comparing them with
the OAs (Operating Ampère) as specified in
this Manual in order to avoid abnormal electric
absorptions.
B11) Check the delivery temperature with a digital
thermometer.
B.12) Verify the superheating, according to Tab. 10.
B.13) (If the emergency power supply option is avail-
able) disconnect the mains supply (via the elec-
trical board of the room) and check that the in-
verter starts automatically.
B.14) Restore the correct calibration of the control
parameters.
B.15) Close the panels of the evaporating and motor
condensing units.
