1Introduction
The 826A Water Cooler is intended to be used as a simple liquid coolant circulator, with Aurora Scientific
800 Series apparatus. The Water Cooler incorporates a brushless DC pump to circulate the water through
an aluminum radiator to exchange heat with the air.

2Quick Start Guide
Setting up an 826A Water Cooler is a simple procedure. This Quick Start Guide will guide you through the
process.
2.1 Attaching the Liquid Coolant Lines
Two lengths of tubing, both six feet in length have been supplied to attach the 826A Water Cooler to an
Aurora Scientific 800-Series Test System. The Tubing has been pre-fitted with the required fittings to
easily connect to the test system. The connection to the circulator uses a threaded compression fitting or
a “hose” screw. It does not matter which side the supply and return are connected to the test system.
To attach the hoses to the circulator, slide on the hose screws over the end of the hoses before mating
the hose to the back of the circulator. Once the hoses have been firmly pressed on, tighten up the hose
screws, to secure the connection (see Figure 1).
Figure 1: Attaching Hoses to Circulator
2.2 Filling the Liquid Reservoir
WARNING: FILL RESERVOIR ONLY WITH COOLANT OR DISTILLED WATER! TAP WATER WILL
CORRODE THE ALUMINUM RADIATOR IN THE UNIT AND CAUSE SEVERE LEAKAGE AND DAMAGE.
Ensure all tubing connections have been completed before attempting to fill the unit. Place the 826A unit
so that it is the highest point in the cooling loop, (above the Test System and tubing). Open the reservoir
cap on the top of the unit. Use a coin or large flathead screwdriver to remove the reservoir cap. A small
funnel has been included with the liquid coolant to minimize spills. Slowly, pour some of the coolant
liquid into the reservoir and carefully fill up to the top (See Figure 2).

Figure 2: Filling Coolant Reservoir
NOTE: Be careful not to overfill the reservoir, since any overflow from the reservoir will drain
directly into the 826A case. You should fill the reservoir to approximately 1.5cm (1/2”) from the
top of the reservoir. If you should overfill the reservoir, screw the cap back on, place a towel under
the liquid circulator and tilt the unit from left to right to drain the liquid from the case. Under no
circumstances should you turn the 826A upside down to drain overflow liquid from the case since
this will damage the fan due to the liquid draining through the fan. .
Once the reservoir has been filled, switch on the 825A to allow the pump to fill the rest of the system and
tubing with coolant. When the system begins running for the first time the fluid inside the reservoir will
begin to drain. As this happens continue to fill the reservoir with distilled water until the draining has
stopped. Once full, replace the cap and unplug the power adapter from the system until ready for use.
If the fluid refuses to flow through the system immediately when power is connected, it is likely that the
pump is still dry. In this case you may attempt to prime the pump by slightly tilting the unit back and
forth to encourage the liquid to flow. Once the pump has begun to circulate, you may replace the
circulation hoses to the test system.
2.3 Positioning the Unit
Positioning the coolant circulator correctly is essential to its proper operation. Firstly the unit should be
positioned a reasonable distance away from the actual test system as vibration from the pump and fan
will make mechanical measurements noisy. If the test system is mounted on a vibration isolation table,
DO NOT locate the coolant circulator on it as this will cause vibration noise to appear in the data.
Since the head pressure generated by the pump is small, the 826A Water Cooler should be mounted
slightly above or at about the same height as the test system. Take care to mount the unit within ±0.5m
of the height of the 800-series apparatus or the circulator will have trouble driving coolant through the
entire loop.

2.4 Module Operation
Once all of the connections have been made and the coolant reservoir filled, the 826A is ready for use.
The coolant circulator does not have a power switch, as it draws its power from a tap on the rear of the
825A. Circulation is therefore turned on by switching the 825A on or off. Once the unit has been plugged
in the fan speed can be set with the two position switch located on the back panel of the coolant
circulator. The low setting is in general sufficient to be used with all ASI 800 Series test systems for most
temperature settings of the 825A. Aurora Scientific recommends switching the fan setting to high when
operating at either extremes of the TEC controller’s range.
The Module is equipped with dry break fittings to avoid any spillage of coolant in the event that the unit
must be moved.

3Maintenance
To prevent air from getting into the system and causing problems with coolant flow, the user should
periodically check the coolant level in the reservoir to verify that it is full (approximately 1.5cm or ½” from
the top) and top up as necessary.
Aurora Scientific recommends replacing the coolant annually to keep your system operating optimally.
If you run out of coolant, distilled water can be used to top up the system. DO NOT use ordinary tap
water, as this will corrode the aluminum radiator inside the unit. Additional bottles of coolant can be
ordered from Aurora Scientific in the event that the coolant supplied with the system runs out.

4.5 Returning Products to Aurora Scientific for Repair
There are a few simple steps that must be completed before returning your product to Aurora Scientific.
1. Obtain a Return Material Authorization number (RMA#).
Contact our technical support department to obtain a RMA #. We require the serial number of the
product along with your contact information, i.e. your name, institution, phone number and email
address.
2. Package your instrument.
Use the original packaging materials if available. If you do not have original packaging then ensure that
the product is wrapped in bubble pack and placed in a sturdy corrugated cardboard box. If you are
returning a force transducer please place the transducer head in the plastic protective box and then wrap
the plastic box in bubble pack and place it in a small cardboard box which can then be placed in the larger
box along with the electronics. For force transducer repairs we require both the transducer head and the
control electronics. Please don't send the power cord. When returning a muscle lever system wrap the
motor in bubble pack and place it along with the lever arm in a small cardboard box and then place that
box in the larger shipping container along with the controller. For muscle lever repairs we require the
motor, lever arm, motor cable and control electronics. Please don't send the power cord.
3. Prepare Customs documents.
Canadian Clients: no customs documents are required, skip to step 4.
European Clients: no customs documents are required, skip to step 4 and ship to Aurora Scientific Europe.
Asia, Australia and New Zealand Clients: no customs documents are required, skip to step 4 and ship to
Aurora Scientific Asia.
USA and Rest of the World Clients: You must include a Commercial Invoice (CI) with the shipment. Please
click this link to download a blank CI.
You can also prepare the commercial invoice yourself instead of using the downloadable form. Print the
document on your company's letterhead and include the following information: Date, Shipper's Name,
Address and Phone Number (your company information), Consignee's Name, Address and Phone Number
(Aurora Scientific Inc. is the Consignee), Country of Origin of Goods (this will be Canada if you purchased
