INTRODUCTION 

 

This  manual  has  been  compiled  by  TCF  Srl  to  provide  the 
installer,  customer  and  user  with  instructions  intended  to 
ensure  the  proper  management  and  use  of  the  air-exhaust 
units  series  CV,  CVM,  CVMI,  EV  from  the  delivery  up  to  the 
commissioning. 
The recommendations which follow are intended to ensure a 
continuous and durative operating life of the air exhaust unit. 
The  procedures  described  below  should  be  performed  by 
skilled  personnel  with  a  good  knowledge  of  air-conditioning 
systems  design  and  operation,  even  though,  thanks  to  the 
unit’s simplicity of design, these could be carried out also by 
those unfamiliar with air handling. 
 
 

1.  

DESCRIPTION OF THE AIR-EXHAUST UNIT 

 

1.1

 

COMPOSITION 

 
The air exhaust unit is made up from: 

 

Return  section  possibly  including  one  control 
damper or grille 

 

Fan section 

 
1.2

 

PERMITTED USE 

 
TCF air exhaust units are designed exclusively for CIVIL AND 
INDUSTRIAL AIR TREATMENT. 
In case of CORROSIVE and/or EXPLOSIVE air flows, a number 
of special technical modifications must be made at the design 
stage which, altogether, adapt the machine for the treatment 
of special air flows. 
The  air  exhaust  units  must  at  all  times  be  used  strictly  in 
accordance with the design conditions established at the time 
of contract in agreement with the customer. ANY OTHER USE 
SHALL  CONSTITUTE  IMPROPER  USE  AND  IS  THEREFORE 
DANGEROUS.  THE  MANUFACTURER  MAY  NOT  BE  HELD 
LIABLE  FOR  DAMAGE  CAUSED  BY  NON-STANDARD  USE  OR 
ANY USE NOT ENVISAGED IN THE CONTRACT.

CONTROL, PACKING, TRANSPORTATION 

 

2.1 

FACTORY INSPECTION OF THE SUPPLY  

 
Prior  to  shipping,  each  TCF  air  exhaust  unit  is  subject  to  all 
the functional tests listed on the attached UNIT INSPECTION 
SHEET. The controls concern: 

 

General machine dimensions 

 

Correct assembly of the various parts and sections 

 

Compliance with the various safety rules in force 

 

Integrity of all the system’s component parts 

 

Application  of  the  identification,  operation  and 
safety notices 

 
On  completion  of  the  inspection,  the  Chief  Inspector  applies 
the  EC  mark  demonstrating  product  compliance  with 
prevailing European Union machine directives. 
 
 
 
 
 

2.2

 

PACKING 

 
Transportation of the machines may be: 

-

 

normal 

-

 

special 

In the former case, TCF Srl does not normally pack the units. 
In  case  of  special  transportation,  the  packing  requested  is 
agreed  at  the  time  of  contract  and  is  entirely  on  the 
customer’s charge. 
 
Fragile components supplied separate from the unit, such as 
control boards etc., are always delivered packed. 
 
2.3

 

LOADING,TRANSPORT,UNLOADING 

 
TCF Srl disclaims any liability for damage occurred to the air 
exhaust  unit  during  loading,  unloading  and  transportation. 
We  therefore  recommend  that  precautions  be  taken, 
including: 

-

 

The  load  must  be  firmly  secured  to  ensure  its 
integrity during transportation 

-

 

Handling must be performed without exerting force 
on  protruding  accessories  (hydraulic  attachments, 
handles, hinges, air locks, protection roof) 

-

 

Do not overturn the sections as you may otherwise 
break internal supports, components and dampers 

-

 

Do  not  subject  the  unit  to  violent  impacts  as  you 
may damage its integrity 

-

 

If  a  forklift  truck  is  used  during  the  loading, 
unloading and handling operations, the forks of the 
truck must be at least the same length as the unit to 
ensure stability (fig. 1) 

-

 

If  the  air  exhaust  unit  is  fitted  with  a  continuous 
steel base frame, handling may be carried out with a 
crane, using cables firmly secured to rods (sufficient 
for  the  stress  involved)  passing  through  the  holes 
provided in the base. 

If  a  crane  is  used,  proceed  as  shown  in  the  illustration, 
using spacers to protect the structure (fig. 2). 
-

 

During  transportation,  protect  the  unit  from 
atmospheric  agents.  Special  care  must  be  taken  if 
the  unit  is  supplied  disassembled  or  designed  for 
internal use.
