Preliminary Operations; Foreword; Inspection; Transport - Liebert HIROSS Hisp SE Manual De Asistencia

1 --- Preliminary operations

1.1 --- Foreword

The following manual covers the installation, operation and
maintenance of HISP air conditioners, which are composed by
an evaporating unit (SE, Split---Evaporating), positioned in the
room, and by a condensing unit (SC, ---Split---Condensing),
positioned outside.
IMPORTANT:
Also consult the manual for the Microface microprocessor con-
trol supplied with the machine (if installed):

1.2 --- Inspection

On receiving the equipment immediately inspect its condition;
report any damage to the transport company at once.

1.3 --- Transport

Always keep the unit vertically upright and do not leave it
S
in the open.
While carrying the unit, avoid exerting any pressure on the
S
upper corners of the package.
Unpack the unit as close as possible to its installation posi-
S
tion. Once unpacked, avoid any impact to its internal com-
ponents.

1.4 --- Sealing the room

To create stable thermo---hygrometric conditions within the
room, proceed as follows:
Vapour seal the walls, floor and ceiling using an imperme-
S
able material.
Make sure that the room is airtight by sealing all gaps, cable
S
entries, etc...

1.5 --- Operating limits

The units are designed to operate within working ranges (see
Tab. 1). These limits are referred to new and correctly installed
machines or for those that have been correctly serviced. The
warranty clauses are no longer valid for any damage or mal-
function that may occur during or due to operation outside the
application values.

1.6 --- Servicing areas

The unit must be provided with a suitable service area, as fol-
lows (see Fig. 3 and Fig. 5). All maintenance of the evaporating
unit can be carried out by removing three of the lower panels, to
gain access to the electric board, to the evaporating, ventilat-
ing, filtering, and Freecooling sections (if Freecooling is
installed).
Access to the motor condensing unit is ensured by removable
panels, fixed through vandal---proof screws (the tool is sup-
plied with the unit).

2 --- Installation

CAUTION: the ambient unit must never be installed out
doors.

2.1 --- Overall dimensions

See Fig. 1 and Fig. 2 for the overall dimensions of the evaporat-
ing unit (SE) and of the external motor condensing unit (SC).

2.2 --- Positioning the indoor unit

Unpack the units as close to the place where it has to be
S
installed as possible. Once unpacked, avoid stress any im-
pact to its internal components.
The air conditioner (indoor unit) can be installed in any in-
S
door location provided it is not exposed to an aggressive
ambient.
Position the indoor unit next to the main heat source.
S
Fix the unit to the ceiling
S
or to the wall by insert-
ing 6 (SE 05---06) or 8
(SE 08---10---13---14)
expansion or thorough
clamps (in this case en-
sure the clamp is
sealed) in the f 8---mm
holes on the two side
brackets.
Make sure the airflow
S
circulate freely.
To allow the servicing of the unit, the Service Area showed
S
in Fig. 5, has to be left unobstructed (in Fig. 5c the
200---mm minimum clearance from the back of the evapo-
rating unit is approximate. It has to be left to ensure that the
refrigerating lines can be connected to the valves on the
back panel).
2.3 --- Freecooling duct connections
(optional)
The air conditioner may be
supplied with an integrated
Freecooling device (option-
al), which uses fresh air from
outside to cool the ambient
without starting up the com-
pressor. The device supplies
the correct cooling capacity
required, through a modu-
lating motor damper.
In this case, the back side of
the unit is equipped with
connections which collect
the outside air, as follows:
standard: double circu-
S
lar hole, for 202 (SE
05---06) or 252
(SE 08---10---13---14)
mm diameter flexible
ducts to be fixed with
metal clamps (optional).
option: single rectangu-
S
lar hole with flange for
560 x 190 (SE 05---06) or 600 x250 (SE 08---10---13---14)
mm duct (not supplied by us).
