What is the best flow rate for each size TECO SeaChill Chiller?

The recommended flow rate is 180-780 gallons per hour for each unit. There is no difference in chiller efficiency between the varying flow rates but it is important to maintain a flow rate that is no less than 180 gph and no more than 780 gph.

My chiller is reading a different temperature than my the thermometer in my tank and I want to set the chiller to match my other thermometer, how do I do that?

Keep "SET" button pressed for a full 10 seconds
The display will show a value of 02 –20 do not change this setting
Push “SET” again
The temperature will be displayed again but less brightly
Pushing the up arrow or the down arrow select the temperature you desire
After five seconds this setting is entered into memory and the display will brighten again and the unit will function normally with the new temperature setting.

My control panel seems to have lost its settings, what do I do?

It sounds like your control panel will need to be recalibrated. Following the directions in your user manual or on the online guide.

Remove the chiller cover.
On the right side of the top of the control panel are a two metal prongs. If you touch both of those prongs simultaneously with a coin (penny, nickel, dime – doesn't matter what type of coin, it will even accept Canadian pennies) it will restore the control panel to factory settings
From there you can follow the direction to set your chiller temperature.

Are the heaters integrated with the chiller so they operate off the same control panel?

Absolutely. The heater and the UV are installed into the heat exchanger and connected directly to the control panel. Both the heater and the UV are concealed so that they do not impair the appearance of the chiller and easily programmed from the control panel.

Why does my chiller have a fuse?

The fuse is a safety mechanism to prevent damage to the compressor should there be any kind of power irregularity. Your chiller comes with a free replacement fuse that is located in the plastic panel holding the active fuse. Should you need the spare fuse, simply open the fuse panel as illustrated and replace the active fuse with the spare. The TR10, TR15 and TR20 all use GGM10 10amp 250volt fuses. These fuses are readily available in the United States or you can purchase them from TECOUS by writing to sales@tecous.com

What do I do if my chiller is leaking from where the shut-off valves go into the housing?

First, turn off the chiller power switch. Next, unplug the chiller. Never mix electricity and water. Next, remove the shut off valves from the chiller. Make sure that the housing is seated firmly. If the housing is loose, re-seat the housing until you hear the housing snap into place (link to instructions to remove housing). Make sure the Housing Ring Nuts are on tight.
Next, check that the Ring Nuts and O rings are properly placed on the Shut Off Valves. Be careful not to break the tabs on the shut off valves. The tabs are there to prevent the water pressure pushing the Shut Off Valves out far enough to leak.
Tighten Ring Nuts firmly, seating the O-rings.

It says the chiller takes ¾' or 5/8” i.d. tubing. How does this work?

The Shut Off Valves have two nipple adapters. The smaller of the two fits 5/8” i.d. tubing. In order to use ¾” i.d. tubing you must remove the first ring nut so that the ¾” i.d. tubing can go back to the larger nipple.

I've lost the o-ring that goes into the valve? How can I replace it?

All parts can be ordered through Fritz Industries, email us at service@tecous.com or call 800-955-1323 ex.158

What is the proper technique for storing a chiller?

If it has been used, drain as much water out as possible. You can tilt the chiller to do this, but make sure the chiller sits flat for at least a couple of hours before using again to give the coolant time to settle. It's best if you can put it in the original box with the Styrofoam to protect it, but so long as it is upright, it should be okay.

Troubleshooting
Problem	Cause(s)	Solution(s)
Display does not light up	No electricity.	Check that the Power Supply Cable is correctly connected to both the chiller and the outlet. Check that the power switch is in the “I” or on postion Check that the fuse has not been burned out
Display reads "AL1"	Dry air filter	Clean the Air Filter as described in 10. Chiller Maintenance
	Ambient temperature too high	Lower the ambient temperature to below 95 ° F/35 °C
	Obstructed ventilation gate	Remove the obstruction or create a ventilation hole as described in 1a iv-vi Safety Precautions above
	Broken fan	Contact service@tecous.com
Display reads "AL2"	If the UV sterilizer is installed this message indicates that the UV lamp needs replacing	Replace the UV lamp with an appropriate TECO UV lamp replacement available on this website.
Display reads "E1"	Temperature probe has been damaged	Contact service@tecous.com
Display reads "E2"	Heater is damaged	Contact service@tecous.com
The temperature displayed is not correct	Water may not be circulating through the chiller correctly	Check for obstruction in tubing. Check that pump is working.
The temperature displayed is not correct	Heat/Cooling is lost through long, uninsulated tubing	Reduce the length of tubing as much as possible, insulate the tubing.
