3.4 OPERATION CONDITIONS
The unit can be used in rooms normal according to IEC 60364-5-51, resp.
ČSN 332000-5-51 ed. 3, ČSN 332000-1 ed.2. The ambient
temperature must be between -20 and +40 °C.
The unit can transport air without solid, fibrous, sticky, aggressive chemical and explosive additives. The maximum permissible supply air
temperature must not 40 ° C. The maximum humidity of the air flowing through the unit is 17 g / kg s.v. (84 % r.h. at 25 °C).
If, due to the immediate climatic conditions, the humidity of the outdoor intake air reaches 100 % r.h. (wet steam), it is at the operator's discretion
whether to keep the unit running with the risk of temporary separation of moisture on the internal parts
of the unit (eg filters, flaps,…). This
humidity cannot be the subject of a complaint.
3.5 DECLARATION OF CONFORMITY
This product type has been tested by the authorised person no. 227, Výzkumný ústav pozemních staveb
– Certifikační společnost s.r.o., Pražská
16, 102 21 Praha 10
Hostivař, and a certificate has been issued to it. For a unit of the above type is issued a "Declaration of Conformity” within the
meaning of Act No. 22/1997 Coll. as amended.
4. TRANSPORT, STORAGE, ACCEPTANCE
On the loading surface of the vehicle, the unit must be sufficiently secured against slipping and tipping over. The unit is wrapped in PE foil and
placed on transport the pallet. The unit is fixed to the transport pallet by means of textile or plastic tie-ups.
During loading and unloading by the fork-lift the unit must be lifted suspended on the transport pallet. When transporting the unit supplied without
the transport pallet it is necessary to support the unit on the underside over the entire surface to prevent damage and
to pay attention to the
condensate outlet opening on the underside of the unit
. During lifting by a crane, it is necessary to pass the ropes through the transport pallet
or under the unit to prevent their slipping. THE UNIT CAN BE HANDLED ONLY BY SUPPORTING OR TYING UNDER THE UNIT FLOOR - THE
UNIT CANNOT BE LIFTED BY THE CEILING OF THE UNIT OR OTHER PARTS (SUCH AS A/C FLANGES, EXCHANGER OUTLETS ETC.)
Ensure proper balancing of the transported unit. The ropes above the unit must be stretched to prevent damage. The outdoor variants of the units
are fitted with transport profiles for safe passing of slings under the unit bottom.
The units must be stored in dry and dust-free areas where the ambient temperature does not fall below + 5 °C. The unit must be protected during
storage against mechanical damage, dirt and corrosion caused by permanent condensation of water vapour on the surface of the unit. During
storage, it is necessary to protect the units against snow, rain and other weather conditions (store in a covered warehouse).
When accepting the unit, it is necessary to check whether the product was delivered in the agreed design and extent, whether it was not
damaged during transport, whether there is no condensed water under the plastic wrap (if there is moisture under the packaging, unpack the
unit and dry in a covered dry place) . In case of damage during transport, the transferee must record the extent of damage in the Delivery Note,
obtain and send photo documentation to S&P UK Ventilation Systems
Ltd
.
Failure to comply with this procedure exposes the transferee to the
risk
of rejection of the complaint by S&P UK Ventilation Systems
Ltd
.
!
CAUTION!
The unit shall not be transported above
persons!
!
CAUTION!
The holes in the frame and legs are not
intended for the unit hinging.
CAUTION!
!
Units with direct evaporator (marked DX and DXr in the unit code)
must be equipped with a mixing flap (marked MX in the unit code),
which ensures, if necessary, min. condenser/evaporator inlet
temperature of +10 °C.
CAUTION!
For units with a direct evaporator (marked DX and DXr in the unit code), the
design air flow through the unit must be observed
when
!
operating the direct evaporator/condenser. It is acceptable to reduce the flow in cooling and heating mode by a maximum of 20 % of the
design air flow. For proper operation of the direct evaporator, it is necessary to observe the necessary heat or cold consumption from the
heat exchange surface of the evaporator/condenser. If the design amount of energy is not consumed, the condensing unit / heat pump may
report a fault in the pressure protections (LP, HP) of the cooling circuit and the condensing unit / heat pump may cycle in ON/OFF mode.
