Figure 18. Water Meter Set Up
• The pressure of the incoming water is 25 psi or greater on a pipe (¾” for TSDC, 1” for
TSDC2 and TSDF2).
• There are no interruptions of water delivery when the unit is on Pre-Cooler Mode.
• The controller is properly set up.
• The Pressure Regulating valve is properly maintained and tested biyearly.
– This water meter will automatically measure the amount of water that passes
through the make-up valve in Gallons and monitor it during specified periods of
time. The meter has an accuracy of +/- 5%.
Water Meter Set-up (Optional)
When the unit is started up for the first time, the start and finish dates will be 00/00 and
0:00.
• The first two numbers are the Month/Day; for instance, if the counter was to be set
from April 19th until May 7th, the start should read 04/19 while the finish should
read 05/07.
• The timer numbers are the start/finish times with hours in the 24-hour format and
minutes; for instance, if the timer should start at 6:00 AM and finish at 4:30 PM, the
monitor would read “Start 6:00” and “Finish 16:30”.
Pre-Cooler Pad Water Flow (For TSDC2 and TSDF2 Models Only)
Make-Up Pressure Balancing Valve
A minimum water flow must be distributed over the Pre-Cooler Pads as per the minimum
water flow rates (see Table 6). The water flow of the make-up will depend on the supply
water pressure. The pressure balancing valve will balance the pressure to the correct value.
This valve will be preset at the factory. The correct values can be found in Table 6.
• Change the pressure by rotating the knob. See callout 1 in Figure 19.
• Check to ensure the pressure on the gauge exactly matches what is listed in Table 6.
