Delivery, handling, reception and storage 

 

Delivery 

Kitchen  hoods  are  bulky  units

;  it  is  the  buyer’s 

responsibility to coordinate adequately the delivery on 
site in order to have the best mode of transport such 
as flat bed, small truck for narrow access or tailgates. 

 
Handling 

The buyer must provide necessary equipment on site 
to unload the truck.  When using a forklift for any item 
over  6  foot  (1.8  meter),  the  forklift  must  be  equipped 
with long forks. 

 
Reception 

Upon reception, inspect the material to make sure it is 
in good condition before signing the bill of lading or any 
approval document provided by the carrier.  If there is 
damage,  write  it  clearly  on  the  bill  of  lading  or  any 
approval document provided by the carrier.   As soon 
as  possible,  advise  Cadexair  and  provide  pictures  of 
the damaged equipment. 
 
Verify the packing slip attached to the bill of lading to 
make sure all the items listed on the packing slip are 
received.  It is possible that some items are note sent 
in  the  same  shipment.    Refer  to  the  packing  list 
included with the bill of lading for verification. 
 
Claims on missing items must be sent within 72 hours 
following the reception of material.  If claims are done 
after this delay, Cadexair reserves the right to refuse 
the claim. 
 

Storage 

Do not store the exhaust kitchen hood outside; avoid 
exposing the exhaust kitchen hood to the sun and to a 
temperature above 35° Celsius.  These conditions can 
affect  the  adherence  of  the  protective  film  glue 
protecting the exhaust kitchen hood and may damage 
the stainless steel when removing the protective film. 
 
  

 

Installation 

 

IMPORTANT 

Cadexair does not take responsibility for 
the  installation  of  the  exhaust  kitchen 
hood on site unless it is clearly stated in 
the sales contract. 
 
A commercial exhaust kitchen hood must 
always  be  installed  according  to  the 
applicable  NPFA  96  edition  and  local 
standards. 
 
Cadexair  does  not  recommend  walking 
or standing on top of the exhaust kitchen 
hoods.    These  actions  may  damage  and 
deform the exhaust kitchen hood which 
will  void  the  guaranty.    If  an  access  is 
mandatory, installed boards to distribute 
the weight evenly on the exhaust kitchen 
hood joints and not to the center of the 
stainless  steel  sheets.    If  needed, 
additional  supports  must  be  used  to 
support the boards. 

Material clearance  

Make  sure  to  respect  the  clearance  standards  from 
combustible  and  semi-combustible  material.    The 
exhaust  kitchen  hood  must  be  installed  3  inches 
(75mm) from semi-combustible classified material and 
18  inches  (460mm)  from  combustible  material.    This 
clearance standard is applicable to walls, ceiling and 
structural components of the building.  Verify with the 
fabrication plans if clearance reduction methods have 
been applied. 

Kitchen exhaust hood positioning 

Make  sure  to  respect  the  kitchen  exhaust  hood 
homologation  when  installing.    The  hood  must  be 
installed to 78 inches (1980mm) from the finished floor 
in the front.  The exhaust kitchen hood must have an 
overhang  of  6  inches  (150mm)  on  each  side  and  an
