TC20i Temperature Control Instrument
Overview
Designed to work with Optimec JCF, JCM, JCFD, SAG and is830 instruments, the TC20i
provides a neat and efficient solution, to enable the measuring and inspection of
soft contact lenses at a constant temperature. With full electronic control the TC20i can
maintain cell measuring temperature within the range 15 - 40 Degrees Celsius (+/- 0.5deg).

TC20i Temperature Control Instrument
Set-Up Detail
1. Position the TC20i to the right of the Optimec JCF, JCM, SAG, JCFD or is830 instrument.
2. On the left hand side of the TC20i is a cooling fan and it is EXTREMELY IMPORTANT
that it is not obstructed, and that a minimum 10cm space is maintained beteween it and
any other object. Failure to do will restrict the air flow and may result in the failure of the
internal heat exchanger.
3. Take the clear silicon tube leading from the top of the Peristaltic Pump and connect to the
plastic tube connector on the right hand side of a JCF and JCM analysis cell or to the
upper connector of the manifold block on the right hand side of a SAG instrument.
4. Take the clear silicon tube leading from the side of the TC20i cabinet (longest tube) and
connect to the plastic tube connector on the left hand side of a JCF,JCM, JCFD or is830
analysis cell or to the lower connector of the manifold block on the right hand side of a
SAG instrument.
5. Position the temperature sensor in the analysis cell of the JCF or using the clip bonded
into the analysis cell of a JCM, SAG or is830 instrument.
6. Fill the analysis cell with saline to the correct level (see JCF, JCM, JCFD,SAG or is830
manual).
7. Insert the power lead included with the TC20i into the plug at the rear of the instrument
and switch on the power at the wall. Switch on the TC20i using the switch at the rear
of the instrument.
8. The Green LED (Power) will illuminate to confirm that the instrument is on.
9. When switched on the Peristaltic Pump will rotate and draw saline from the analysis cell
As this happens, the saline level in the cell will fall and bubbles will be seen as the pump
expels air during priming. Top up the saline level in the cell until bubbles no longer appear.
WARNING:
IF SALINE IS SPILT, DISCONNECT THE TC20i FROM THE ELECTRICAL SUPPLY
Avoid spilling saline on the TC20i as it is very corrosive, damaging the paintwork, and should
it come into contact with the electronics, may cause a serious instrument failure and possibly
a risk of electric shock.
WARNING:
DISCONNECT FROM THE POWER SOURCE if the side panels may be removed to check
that no saline is in the cabinet, and left to dry naturally if there is. This is the only circumstance
for the side covers to be removed as there are no user serviceable parts within the cabinet.

TC20i Operating Instructions
Temperature Adjustment
When the TC20i leaves Optimec, it will be set to a working temperature of 20 Degrees
Celsius. Should this be the temperature you wish to to work at, you will not need to make
any adjustments to the instrument.
The working temperature can be changed if required in 0.1 Degree Celsius increments
in the range15 - 40 Degrees Celsius.
Should you wish to change the working temperature, proceed as follows:
1. On start up the instrument is in Working Mode with the Green LED (Power) illuminated.
2. Press the Return Arrow (Set Switch) to illuminate the Yellow LED. The instrument is now
in Temperature Set Mode.
3. Using the Up Arrow (Raise Temperature) or the Down Arrow (Lower Temperature), press
until the required temperature is displayed on the Temperature Readout.
4. Press the Return Arrow (Set Switch) returning the instrument to Working Mode.
5. If the Return Arrow (Set Switch) is not pressed within 10 seconds of using the Up and
Down Arrows the instrument will automatically return to Working Mode set with the last
selected temperature.
1. On start up the instrument is set in Working Mode.
2. The Blue LED (Cooling Indicator) or Red LED (Heating Indicator) will illuminate until the
saline solution reaches the set temperature.
3. When the set temperature has been achieved the Green LED (Temperature Reached)
will illuminate.
4. The TC20i will maintain the set temperature within +/- 0.5 Degrees Celsius.
5. As the electrical load required to achieve set temperature varies, it is normal for the note
of the fan to change.

TC20i Operating Instructions
Maintenance
The TC20i is a very reliable instrument, and if used carefully, will function reliably for many
years. In order to keep your TC20i in the best condition, Optimec strongly recommend that
the following procedures are carried out as part of a planned maintenance regime.
PERISTALTIC PUMP TUBE: The peristaltic pump tube will wear over time and the pump
efficiency will fall as a result. Any reduction in the quantity of saline flowing through the
TC20i can have a dramatic effect on the capabilities of the unit and may lead to the failure
of the internal heat exchanger.
Daily visual inspection of the tube will show if the tube has worn and will be seen as a
permanent flattening.
When used 8 hours per day, 5 days per week it is recommended that the tube be replaced
at 3 monthly intervals.
Replacement peristaltic tubes are available direct from Optimec. Refer to Page 6 for
replacement procedure.
CARTRIDGE FILTER: The disposible cartidge filter removes debris from the saline solution
down to 25 microns. Over time the filter will become blinded as particulates are removed
from the saline solution. A blinde filter wiil reduce the flow of saline which will effect the
capabilities of the unit and may result in heat exchanger and/or pump failure.
When used 8 hours per day, 5 days per week it is recommended that the filter be replaced
on a monthly basis.
Replacement cartridge filters are available direct from Optimec.
TEMPERATURE SENSOR: The sensor is a serviceable part and failure is indicated when
the Temperature Readout displays the message “ERR”.
Spare temperature sensors are available direct from Optimec.

Peristaltic Tube Replacement
First remove the external tubes from the peristaltic pump.
Then use a flat bladed screwdriver to prise the pump rotor cover from the rotor casing.
Slide the peristaltic tube from under the the pumphead rotor by hand.
.
Discard the old tube and fit the new tube by reversing the removal procedure.
Refit the pump rotor cover before use to protect the operators fingers from injury.

The Cartridge Filter is held in place by a clip and the tubes are a push fit onto the tubing
connectors and reducers. Please ensure when replacing the tubing that the tubes are
pushed fully over the connectors and that there are no kinks present. On start up check
that there are no leaks. If leaks are found turn off the TC20i immediately and recheck all
tube connections.

Ambient Temperatures
The TC20i is an electrical driven instrument and as such, if not used correctly, can be a
source of electric shock and therefore could be hazardous to life if the following precautions
are not observed.
NEVER operate the instrument in damp or wet conditions.
NEVER run the instrument with the covers removed.
NEVER operate the instrument from a voltage other than that specified on the serial plate
on the rear of the cabinet.
UNAUTHORISED disassembly, repair or modification will void the one year warranty and
could result in injury or electric shock.
If a fault should develop, switch the instrument off and remove the electrical supply lead.
You should then contact Optimec Limited and refrain from using the instrument until
guidance is received.
If for any reason the TC20i requires servicing or repair after the the warranty period, please
contact Optimec.
