Installation UV Lamp Installation UV Lamp Installation Locate the UV chamber inside the left door of the Thermo Scientific TII (Figure 3-10). Install the UV Lamp as follows: Figure 3-10 UV Chamber 1. Disconnect the power cord from the unit.
Cartridge / Membrane Installation Your Thermo Scientific TII has been shipped with one RO membrane for the 12 lph unit, or two RO membranes for the 24 lph unit, which you will install. The Startup Kit (D502138) includes a prefilter, MPS cartridge, carbon filter, and cartridge pack, and must be purchased separately.
Carbon Filter Installation Chlorine can also damage your membranes, resulting in premature membrane failure. Therefore, your Thermo Scientific TII uses an extruded carbon filter to remove chlorine from your feed water. Install the carbon filter as follows: 1. Remove the carbon filter (Part Number D502115) from its packaging and wet the o-rings with water.

(1.83 m) long with a 1/4” O.D. x 1/4” N.P.T. tubing adapter on one end. The atmospheric drain fitting is located on the lower left corner in the rear of the Thermo Scientific TII. 2. Install the tubing adapter into an atmospherically vented drain and route the tubing to the Thermo Scientific TII drain connector, ensuring that there are no kinks.
Preparation in this section. When new RO membranes are installed in the Thermo Scientific TII, the membranes should be rinsed to remove all traces of preservative from the membranes. 1. Ensure that the feed water and drain connections are in place and power connections are made.
Answer yes to both questions. Once initiated, the rinse procedure will last two hours, and will stop automatically. CAUTION Do not allow the Thermo Scientific TII to operate unless water is available to the unit. WARNING Use a properly grounded electrical outlet of correct voltage and current handling capacity.
Figure 3-21 Typical TII Display Prior to beginning the cleaning procedure, ensure the Thermo Scientific TII is attached to a suitable reservoir and that all water and electrical connections between the Thermo Scientific TII and the reservoir are in place. The system should be cleaned before the first use, before a new cartridge pack is installed, or whenever the one-year cleaning timer alerts you.

By purchasing the optional N.I.S.T. calibration module (Catalog No. E1403X5), it is possible to perform a calibration of the DI resistivity meter board of the Thermo Scientific TII System purity sensing electronics traceable to N.I.S.T standards. This calibration should be repeated at least once a year.

1. Make sure the printer and Thermo Scientific TII are turned OFF. 2. Connect the Thermo Scientific TII to the printer via the RS232 port on the back left side of the unit. Use the tan printer cable included with the Epson printer. Plug the printer power cord into an electrical outlet.
7. The system should be left in RUN during the workday. 8. If the Thermo Scientific TII is to be shut down for an extended period of time, the unit should be completely drained and the cartridges and membrane(s) removed and refrigerated to prevent the growth of bacteria.
Refer to “Automatic Dispensing” in the “User Settings” section of this manual for more information. Four blank buttons appear on the control panel and perform various functions as defined on the display throughout operation. See the Normal Operation section for more detailed descriptions. TII Water System Thermo Scientific...
In RUN mode, the pump recirculates water through the cartridges and the UV lamp. It is recommended that the Thermo Scientific TII be left in RUN mode during the day. In RUN mode, the purity meter display indicates the resistivity (temperature compensated to 25°C) of the water available for dispensing.
RO membrane once every three hours and fifty-six minutes of operation. This prevents buildup on the RO membrane. A timer in the Thermo Scientific TII counts the hours power is applied to the unit. When the timer reaches three hours and fifty-six minutes, the Thermo Scientific TII initiates a four minute flush if the unit is in the RUN or STANDBY Modes.
MENU. During the four minute flush, water is sent to drain through the drain tubing and the display will show remaining minutes. After the timed flush has ended, the Thermo Scientific TII will return to the mode (IDLE, RUN or STBY) it was in when you initiated the flush.

“Error Conditions” section later in this manual to interpret the error. Setting the Feedwater Chlorine Level To ensure that the RO membrane(s) in the Thermo Scientific TII are not damaged by free chlorine in the feed water, the system electronically tracks the amount of chlorine processed by the carbon prefilter (D502115) and alerts the user when the carbon capacity is exhausted.
Display Contrast The Thermo Scientific TII display can be adjusted based on user preference. Set Units The Thermo Scientific TII can display readings in a variety of units. Use this option to set desired units. Printer Attached The Thermo Scientific TII can print readings to an optional printer accessory (AY1137X1).

The carbon filter incorporated in your Thermo Scientific TII provides a combination of filtration and chlorine removal. There is a timer built into the Thermo Scientific TII which will alert you when the carbon requires replacement. When the “Routine Care” light illuminates the carbon filter may need to be replaced.
Clean your Thermo Scientific TII and replace the cartridge pack when the product water purity drops below acceptable levels of resistivity, when organic levels become too high, or if a new 0.2 micron filter clogs rapidly after installation even though the cartridge pack was thoroughly rinsed before the 0.2 micron...
It is recommended to replace RO carbon prefilter when replacing the RO membrane. Refer to the Carbon Filter Installation section of this manual. 1. Turn off the Thermo Scientific TII and disconnect it from the power supply. 2. Disconnect inlet feed water connection. 3. Locate the RO membrane(s) inside the left door (see Fig. 9).
The ultraviolet lamp requires periodic replacement. Lamp life will vary according to the number of times the Thermo Scientific TII is turned on and off. Lamp life is based on the Thermo Scientific TII being operated in the normal recirculating mode during regular working hours and then placed in the Standby mode during off hours.
