3.1.

 

RECEIVING   

§

 

The   box   cooler   is   usually   delivered   in   a   wooden   case.   
Carefully   open   the   case   upon   receipt   and   check   if   all   
items   are   present   (check   against   the   bill   of   lading)   and   
inspect   all   items   for   damage.   

§

 

Note   any   damage   or   missing   items   on   the   carrier’s   bill   
of   lading   and   file   a   claim   immediately   with   the   freight   
company.   When   possible,   take   pictures   of   the   damage.   

§

 

Notify   Duramax   Marine®   immediately   when   damage   is   
observed   or   when   items   are   missing.   

§

 

Close   the   case   immediately   after   inspection,   to   avoid   
that   the   items   in   the   case   get   lost   or   damaged.   

§

 

Leave   the   box   cooler   inside   the   case   until   immediately   
before   installation.

INSTRUCTIONS   FOR   TRANSPORT,   

HANDLING   AND   LIFTING   

   

   
   
   
   
   
   
   
   

   

   

Heavy   loads   

Crushing   or   severe   personal   injury   caused   by   a   
falling   or   swinging   load   due   to   incorrect   handling   
or   lifting.   

Ø

 

Transportation,   handling   or   lifting   of   the   box   
cooler   shall   only   be   carried   out   by   suitably   
trained   and   qualified   personnel.   

Ø

 

Use   lifting   equipment   with   adequate   lifting   

capacity   and   appropriate   lifting   accessories   
with   hooks   and   shackles   that   are   suitable   for   
the   lifting   provisions.   

Ø

 

Stand   clear   of   load.   

Ø

 

Wear   safety   helmet   and   safety   shoes.   

§

 

Lift   the   tube   bundle   only   by   four   M16   eyebolts   

4

   (DIN   

580).   Tighten   them   into   the   4   threaded   holes   in   the   

tube   sheet   which   are   designated   for   this.   If   needed   the   
position   of   the   eyebolts   must   be   adjusted   with   
suitable   washers.   Do   not   insert   the   point   of   a   hook   in   
an   eyebolt   but   use   a   shackle.   Lift   only   by   using   all   4   
eyebolts   simultaneously   (see   fig.   2).   Do   not   insert   the   
point   of   a   hook   in   an   eyebolt   but   use   a   shackle.   

                                                                                                                                                                                                            

4

   The   eyebolts   are   not   part   of   the   scope   of   supply   from   Duramax   

Marine®.   

§

 

Lift   the   water   cover   only   by   the   4   lifting   holes   provided   
in   the   end   plates   (see   fig.   2).   

§

 

Pay   attention   to   the   weight.

   The   weight   of   the   box   

cooler   is   shown   in   the   technical   specifications   at   the   

end   of   this   manual   and   on   the   type   plate.   

§

 

Do   not   use   nozzles,   flanges   or   other   protruding   parts   
to   move   or   lift   the   box   cooler.   

§

 

Prevent   damage   to   the   box   cooler,   especially   the   
duroplast   coating.   

A   damaged   coating   (also   small   

damages)   will   lead   to   accelerated   (galvanic)   corrosion.   
Small   damages   can   be   touched   up   by   a   special   two-­‐

component   repair   set,   which   can   be   ordered   from   
Duramax   Marine®.   

§

 

Prevent   impacts   and   dropping.   

§

 

Pay   attention   to   the   centre   of   gravity,   do   not   swing,   
cant   or   tilt.

3.3.

 

SHORT   AND   LONG   TERM   STORAGE   

The   box   cooler   may   need   to   be   stored   for   a   longer   period   
of   time   prior   to   installation.      

§

 

Leave   the   box   cooler   inside   the   wooden   case   in   which   
it   is   supplied   to   protect   it   against   damage.      

§

 

Store   the   case   in   a   dry,   well-­‐ventilated   area,   protected   

from   the   weather,   preferably   indoors.   

§

 

Avoid   wide   temperature   fluctuations   to   prevent   that   
condensation   and   moisture   enter   in   the   box   cooler.   

§

 

Do   not   stack   other   objects   on   top   of   the   case.   

§

 

Do   not   use   the   case   as   a   climbing   aid
