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,

1/2inch I.D. N.P.T. The 2 adapters sets supplied are for1/2inch I.D. tubing and 5/8inch 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 ONbutton. 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.

Section 3 - Operation

3.1 Power Requirements

Caution! Be sure that the power supply is the same voltage as specified on the nameplate

With the chiller plugged in (before pressing the POWER ONbutton), the display responds by showing

standby (....). If there is no response, check that the circuit breaker on the rear of the chiller is in the

ON position. An extension cord is not recommended.

3.2 Temperature Setting and Adjustments

After setting up and filling the chiller:

1. Press the POWER ONbutton. 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.

3.6 Draining the Unit

Press the Power Off button and unplug the chiller. Remove drain plug and reservoir cap and allow

unit to drain. Syphon or use a small manual pump to remove all fluid from the reservoir.

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.

4. Your set temperature and other settings will have to be reset.
