Setting   up   the   T257P   Temperature   Control   System   

4.1

Follow   the   steps   outlined   below:   

1.

 

Connect    the    T257P    chiller    to    the    application    using    fluid    transport    hoses    from    ThermoTek    or   
hoses   using   Colder   PLC   or   PLCD   insert   fittings,   or   custom   fittings   as   configured.   

2.

 

Keep   the   chiller   horizontal   and   on   a   level   surface.   

3.

 

Make   sure   there   is   a   minimum   12”   clearance   and   free   path   for   flow   of   air   entry   and   exit   at   the   
left   side   and   right   side   of   the   T257P   chiller   prior   to   operation.   

4.

 

Check   to   see   if   the   power   switch   is   in   the   OFF   position.   

5.

 

Insert    the    fluid    transport    hose    into    the    T257P    Chiller.    If    the    fittings    are    the    standard    Colder   
quick   disconnects,   hearing   a   “click”   indicates   a   secure   connection.      Check   the   labels   next   to   the   
ports   for   coolant   flow   direction.   

6.

 

Remove   the   reservoir   cap   and   add   coolant   to   the   reservoir   until   the   fluid   reaches   the   bottom   of   
the   neck.   Please   refer   to   the   technical   information   section   for   recommended   coolants.         

7.

 

Close   the   cap   securely   to   the   reservoir.      Make   sure   not   to   overfill   the   reservoir.   

8.

 

Install   the   appropriate   end   of   the   power   cord   into   the   unit.   

9.

 

Plug   the   male   end   into   the   AC   voltage   outlet   within   the   device   specified   voltage.      Please   refer   
to   the   technical   information   section   for   input   voltage   specifications.   

   

 

Startup   Procedure   

4.2

1.

 

Verify   that   the   T257P   Chiller   is   plugged   into   the   appropriate   AC   voltage   outlet.   

2.

 

Verify   the   T257P   Chiller   coolant   ports   are   connected   to   the   application.         
A.

 

It   is   recommended   that   insulated   tubing,   with   minimum   3/8”   ID,   be   used   when   connecting   
to   the   application.         

B.

 

Even   if   the   application   flow   path   is   smaller   than   the   recommended   ID,   it   is   important   to   use   
the   recommended   ID   for   the   transport   hose   to   minimize   system   pressure   drops.   

C.

 

Do   not   use   Copper   or   Brass   components   in   the   application-­‐wetted   path.      This   will   adversely   
impact   the   T257P   Chiller   heat   exchanger.   See   the   technical   information   section   for   T257P   
Chiller   wetted   path   component   list.   

3.

 

Turn    ON    the    T257P    Chiller.        The    power    switch    is    located    on    the    right    side    of    the    device,   
adjacent   to   the   coolant   ports.   

4.

 

When   the   unit   first   powers   up   a   rotating   circle   will   appear   on   the   LCD   screen   located   on   the   
front   of   the   unit.   

5.

 

The   unit   will   automatically   start   and   enter   the   RUN   Mode   with   the   fans   and   pump   active   and   
the   control   system   set   to   control   the   operating   fluid   to   20   C   or   the   last   set   temperature.
