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.
