Can I calibrate the temperature sensor?

Yes, the temperature sensor and can be calibrated by using the controller keypad. To calibrate the sensor, begin by looking at the current temperature displayed on the LCD and recording it.  Press both arrow keys simultaneously for 10 seconds until "ca" appears or a number from -4 to +4 appears.  The calibration should be set at 00.  From this point press the up or down button to match your chillers thermostat reading to your desired reading.  Press "set" again, whcih accesses the differential setting. Pressing "set" again, the chiller will resume to normal operation after a few seconds.

Can the chiller be installed under a stand?

Although not advisable, the Prime Mini-Chillers can be installed under well-ventilated stands.  The stands must have an open front & back allowing the heat to escape from the stand.

How do I change the temperature differential?

We pre-set the temperature differential in each of our Prime mini-chillers to 2 degrees F.  We do not advise changing the differential unless your application is a specialized applications.  To change the differential, press both arrow keys simultaneously for  10 seconds until "ca" or a number between -4 and +4 appears. Press the set key again until a "d" or "f" with a number appears. Press the "up" button to change the differential, then hit "set".  The chiller will resume to normal operation after a few seconds.

How loud are the Prime Mini-Chillers?

Current USA understands the value of silence, that’s why we've made our mini-chillers so quiet.  Both the 1/15th & 1/10th hp chillers are virtually silent and have a rated decibel rating of 25-35db.

I just plugged my chiller in and it is making a banging/rattling noise, is it broken?

If your Prime chiller makes a rattling noise upon installation, unplug the unit and check for shipping damage around the housing or the base.  If damage is found, contact your retailer to inform them of freight damage.  If no damage is found, follow the following steps:  1. Turn the unit upright and allow it to sit for 24-hours.  After 24-hours, plug the unit back in and see if the chiller will operate normally. 2. If the chiller still rattles, contact Current-USA technical support.

The chiller is running, but it is not cooling the tank.

If your chiller is plugged in, and seems to be working, use these guidelines to see if it isn't working correctly: 1. Ensure that the chiller has been correctly sized for your application.  Check our website for sizing guidelines or contact your retailer.  2. If the chiller is blowing out hot air, then it allow it to run for a longer period of time.  The hot air is heat being removed from your aquarium water, so it is likely operating normally.  3. Follow the guidelines in the instructions regarding proper placement as ventilation is key in chiller efficiency.  If warm or hot air is being sucked into the chiller, it may take longer for the chiller to cool the water.  4. Ensure that the condenser screen on the front of the chiller is clean.  Remove it by pressing the tabs on the screen and wash with warm water.  Allow it to dry before re-inserting it onto the chiller front.

What is the evaporator made of?

All chillers made by Current-USA use titanium heat exchangers that provide the highest protection from the corrosive elements in saltwater.

What is the proper water flow rate through the chiller?

Our Prime 1/15th hp nano chiller should be provided a water flow rate of approximately 3-10 gpm (180-300 gph.)  The Prime 1/10th hp chiller should be provided a water flow rate of approximately 7-12 gpm (420-720 gph.)

What maintenance is required on the chiller?

The only maintenance required on our Prime Mini-Chillers is to ensure that the inlet air screen filter is always clean.  Pet hair and dust can impede air flow, therefore reducing the efficiency of the chiller. Check out our Newsletter section of our website www.current-usa.com for maintenace tips for the chillers.

Where is the best location to install the chiller?

For maximum efficiency, water chillers are best located next to an aquarium where the back and front have at least 18" of space for proper ventilation.
