Section 2 - Set Up
Before proceeding, be sure all power is off
2.1 Location
Locate the chiller on a strong, level surface. Insure easy access to the top cover and position
the chiller for unobstructed air flow through the front and rear screens. The front wheels can be
locked to keep the chiller in place while in use. Avoid voltage drops by using properly grounded
power outlets wired with 14 gauge or larger diameter wire. If possible, be close to the power
distribution panel. Minimize low line voltage problems by eliminating the use of extension cords.
2.2 Reservoir Fluids
For most applications above +15°C, distilled water is satisfactory. For operation below +15°C, the
chiller MUST be protected with an antifreeze solution. Ethylene glycol (laboratory grade) and water
in a 50/50 mixture is satisfactory from +15°C to -15°C. Select a fluid that is compatible with the
chiller's wetted parts of brass, copper, polypropylene, PVC, nylon and stainless steel. Only use fluids
that will satisfy safety, health and equipment compatibility requirements. CAUSTIC, CORROSIVE
OR FLAMMABLE FLUIDS MUST NEVER BE USED.
Do not use a flammable fluid as a fire hazard may result.
WARNING!
Operation below +15°C requires antifreeze in the circulating fluid.
2.3 Pump, Hoses and Couplings
To maintain a safe workplace and to avoid leaks, special care should be taken when choosing hoses
and connectors for the chiller.
1. Pressure ratings - Hoses should be able to withstand the largest pressure that they will
encounter. For positive displacement pump models, this is 100 psi.
2. Flexible tubing - Avoid tubing that will expand and take up fluid volume when operating at the
desired pressure.
3. Hose diameter - The fittings on the chiller Outlet and Inlet lines are internally threaded,
1/2 inch I.D. N.P.T. The 2 adapters sets supplied are for 1/2 inch I.D. tubing and 5/8 inch I.D.
tubing. Other fittings can be used if a smaller hose diameter is desired. Remember that the
operating pressure in the circulating system increases when using a smaller diameter hose.
4. Couplings & Clamps - The use of screw-tightened hose clamps is necessary on all joints to
insure good, tight connections. Quick connectors are not recommended because they have the
potential for restricting flow rate.

IMPORTANT!
Chillers equipped with a high pressure positive displacement pump have a pressure
regulator inside of the chiller and a pressure gauge on the control panel. To access this
regulator, remove the rear air grille. The valve is located to the right. On models 6107 & 6705,
6155 the regulator is located center point, upper grille (rear).
The Pressure Valve is FACTORY ADJUSTED to 40psi. If you do NOT want to operate at this
pressure, or do not know what your operating pressure should be, start at a lower operating
pressure. Reduce the pressure by turning the valve counterclockwise (unscrew outward)
before starting the chiller.
With the chiller fully connected and running, read the pressure gauge and turn the regulator
to the desired pressure. If required, an optional external pressure reducing assembly is
available for this pump to reduce the pressure to 10 - 45 psi.
2.4 Setting Up a Closed System or Cooling Coil to the Chiller
1. Connect your closed cooling system to the chiller with hoses or pipes. The direction of the flow
through the system can be controlled by the way the hoses or pipes are connected to the chiller.
The “Inlet” will draw liquid into the chiller; the “Outlet” will pump liquid out.
2. Turn the access panel screws to remove the top cover and expose the reservoir. Turn the filler
cap and lift up to remove. Use a funnel to fill the reservoir with fluid. When full, remove the
funnel, but do not replace the cap at this time. Check hoses and fittings for tightness and be
sure there are no bends or crimps in the hoses.
3. Plug the chiller into the proper AC outlet (unit's electrical requirements on rear of unit). Press
the POWER ON button. The chiller will begin pumping liquid through your system. Check for
leaks.
4. With the pump running, the reservoir's fluid level will decrease as the closed system begins to fill.
Add a little fluid at a time until the level in the reservoir stops going down. This means that your
system is filled and the air has been purged from it. Replace the reservoir cap and turn it
clockwise to lock it. Recheck the cap for tightness.
Note: When chillers with the standard magnetic drive centrifugal pump are connected to an external
apparatus with a built-in flow shut-off, an external bypass loop assembly (pt.# 510-147) may be
needed if operating below 20°C. This bypass assembly continues fluid circulation to and from the
pump even though the main flow to the external apparatus has been blocked.
2.5 Setting Up an Open Bath System to the Chiller
1. Connect hoses to the Inlet and Outlet fittings on the back of the chiller. The "Inlet" draws fluid
into the chiller, the "Outlet" pumps fluid out. Fill the open bath. Considering this flow, position
the hoses in your bath for a good circular flow and stirring motion.
2. Turn the panel screws to remove the top cover and access the reservoir. Turn and lift the filler
cap to remove. Use a funnel to fill the reservoir with the same fluid in your bath. This primes the
pump and helps establish a flow when the chiller is turned on.
3. Replace the reservoir cap and turn to lock it. Check for tightness. Check all hoses and fittings.
Be sure there are no bends or crimps in the hoses, and that the hose attached to the chiller's
inlet is submerged near the bottom of the bath. Secure the inlet and outlet hoses to the open
tank so they do not move when pumping starts. The bath's fluid level will drop slightly as the
hoses in the system fill up with fluid. The bath's fluid must cover the chiller's inlet hose.
4. Plug the unit into the proper AC outlet (unit's electrical requirements on rear of unit). Press the
Power On button. The chiller will begin pumping fluid through your system. Check for leaks.

3.2 Temperature Setting and Adjustments
After setting up and filling the chiller:
1. Press the POWER ON button. The LED display indicates (8888), the power up self test. When the
chiller is turned on, there is a 60 second time-out period. During this time the controller is
performing a self-diagnostic and a balancing of pressure across the compressor inlet and outlet.
(a balanced system reduces the AC current required to start up the compressor and will result in
an extended compressor life.) The pump is active during the start delay period. When the time
out period reaches zero, the compressor starts and the chiller is then fully operational.
Upon completion of the self test, the actual fluid temperature is displayed. Your desired
operating temperature can now be set.
2. Press the SET/MENU button. The degree lights flash indicating the temperature can be set or
changed. Turn the SETTING ADJUSTMENT knob to the desired setting. This setting is accepted
after pressing the SET/MENU button or will be automatically accepted after a few seconds of
keypad inactivity. The degree light stops flashing and the display shows the actual temperature.
3. The SET TEMPERATURE may be checked at any time by pressing and releasing the SET/MENU
button. Allow sufficient time for the chiller to stabilize at the desired temperature.
3.3 Selection of Celsius or Fahrenheit
To change the readout to °C or °F:
1. Press and hold the Set/Menu button until the display reads “UNITS”.
2. Press Set/Menu again then turn the Setting Adjustment knob and select °C or °F.
3. Press Set/Menu or the setting will be accepted after a few seconds.

above the High Limit you select. It is not an over temperature feature which shuts off the chiller.
To set the readout High Limit:
1. Press and hold the Set/Menu button until the display reads “UNITS”.
2. Turn the Setting Adjustment knob until the display reads “HI-L”.
3. Press the Set/Menu button, enter the desired value using the Setting Adjustment knob.
4. Press Set/Menu and the display will again read "HI-L". The Setting Adjustment knob can be
turned to access another menu option or you can wait until the entered value has been
accepted. When the value is accepted, the degree light will stop flashing and the fluid
temperature will be displayed.

Run the unit intermittently (5 to 10 seconds each time) to pump the water from the system. Stop
pumping when the fluid is reduced to a trickle. Running for a longer period will cause damage to the
positive displacement pump. Open the reservoir and use suction or a hand pump to remove any
remaining water.
Prior to storage or shipping: Water MUST be removed from ALL parts of the chiller system, or
an ANTIFREEZE must be added to insure that internal damage does not occur.
3.7 Controller Default Settings
To return to the factory default values:
1. Press and hold the Power On button, then turn off at the circuit breaker.
2. Still holding Power On, hold the Set/Menu button while turning the unit on by the circuit breaker.
3. The controller will display “DEF” and go to the standby mode.

To optimize flow and prevent pump damage due to scale or foreign particles, a filter is included with
the high pressure pump models. How often the filter requires maintenance depends on the
environment and use of the chiller.
To access this filter remove the left side panel. The water filter is located behind the side brace. Grip
the plastic sediment bowl firmly and turn counter-clockwise to remove it. Clean the stainless steel
wire screen found inside and replace it in the filter holder. Do not replace the filter screen unless it is
damaged.
(On models 6105 and 6705, remove the right side panel to access the water filter and pump. On
model 6155, you must remove the top panel in order to remove the side panel. After removing the
side panel, you will have access to the water filter.)
5.4 Refrigeration Air Filter & Air Vents
For maximum cooling efficiency, the condenser and the front and back air vents should be kept free
of dust and dirt. Dirt thermally insulates the condenser coils and reduces the cooling capacity of the
refrigeration system.
Set up a periodic schedule to clean the removable air filter at least monthly. Tap water and mild
detergent is sufficient to clean filter material. Frequency of cleanings depends on the atmospheric
conditions around the chiller as well as length of operating time.
