Installation and Startup

Site Requirements

Ambient Temperature and Relative Humidity

The Chiller is designed for indoor installation in ambient temperatures between 16° and 35°C (60° and 95°F); relative humidity should not exceed 80% (non-condensing).

Location

Install the Chiller on a strong, level surface as close to possible to the process requiring cooling. It should not be installed closer than 4 feet (1.4 meters) to a heat-generating source. If possible, the unit should be located near a suitable drain to prevent flooding in the event of leaks. Do not place it where corrosive fumes, excessive moisture, excessive dust, or high room temperatures are present.

Position the Chiller as close as possible to the power distribution panel. Avoid voltage drops by using a properly grounded power source wired to meet electrical data plate requirements. The use of an extension cord is not recommended.

NOTE: The unit may be located at a level below that of the equipment being cooled. As long as the process remains closed, overflow will not occur when adding cooling fluid to the unit's reservoir.

Clearance

Allow adequate clearance on the front, sides, and rear of the Chiller for access to connections and components. The front and rear vents of the Chiller must be a minimum of 24 inches (61 cm) away from walls or vertical surfaces so air flow is not restricted.

General Considerations

It is the user’s responsibility to ensure that the tubing and fittings connected to the Chiller are compatible with the fluid, temperature, and pressure being used.

• All external piping, tubing, or hoses should be run full size to limit the potential for external pressure drops.

The use of quick-connect fittings is not recommended, as they can cause substantial pressure drops.

• Materials of construction should be compatible with the fluid being used as well as the temperature and

pressure at which the unit will operate.

• Where applicable, always use a back-up wrench when making piping connections to the Chiller.

• Pressure Ratings – Hoses should be able to withstand the highest pressure that they will encounter (100 psi

/ 6.9 bar).

• Flexible Tubing – Avoid tubing that will expand and increase fluid volume when operating at the desired

pressure.

• Hose Diameter – The fittings on the Chiller’s process fluid lines are female 0.5 in NPT. The facility water fluid

inlets and outlets on water-cooled models are female 0.75 inch NPT.

• Facility Water (water-cooled models only) – Should be clean and well maintained. Ideally, the facility water

should be tested monthly to ensure a pH level between 7.2 and 7.8. Add algaecide if algae growth is present.

110-392 10

Process Fluid Connections

The incoming cooling water pressure should be 20 psi / 1.4 bar minimum and 150 psi / 10.3 bar

The Chiller has two internally threaded fittings on the rear of the instrument housing for the process water connections. Two sets of adapters are supplied with the unit for connecting these fittings to the process piping.

The direction of the flow through the system can be controlled by the way the connections are made. Fluid is drawn into the Chiller through the “Inlet” connection; fluid is pumped out of the Chiller through the “Outlet” connection.

NOTE: When Chillers with the standard magnetic drive centrifugal pump are connected to an external

apparatus with a built-in shutoff, an external bypass loop assembly (Part No. 510-147) may be needed if operating below 20°C (68°F). This bypass assembly continues flow circulation to and from the pump even though the main flow to the external apparatus has been blocked.

Facility Water Connections

WARNING: On units requiring facility water, those connections must be made by a licensed plumber.

CAUTION:

maximum.

Water-cooled Chillers have two internally threaded fittings on the rear of the instrument housing for the facility water connections. The cooling water supply should be connected to the facility water inlet on the Chiller. The facility water outlet on the Chiller should be connected to the appropriate return or drain, as required.

The cooling water supply may be from city tap water or a cooling tower. The incoming water pressure should be between 20 and 150 psi / 1.4 and 10.3 bar.

Reservoir Drain

A connection is provided for the reservoir’s gravity drain.

Reservoir Vent

A reservoir vent assembly is provided with Chillers equipped with the heater option to relieve pressure within the reservoir as coolant heats and expands. A connection is provided on the rear of the Chiller for the vent assembly.

110-392 11

Process Coolant

Suitable Fluids

WARNING: For units that use cooling fluids.

Use only fluids that comply with safety, health, and equipment compatibility requirements. Read the safety data sheet for the fluid being used carefully before use.

CAUTION: DO NOT USE

Caustic, corrosive, or flammable liquids Automotive anti-freeze* Hard tap water* Deionized water with a specific resistance >1 meg ohm Concentrations of acids or bases Solutions with halides: chlorides, fluorides, bromides, iodides, or sulfur Chlorine bleach Glycerine Syltherm fluids

At temperatures above 40°C, additives or mineral deposits can adhere to the heater. If deposits are allowed to build up,

the heater may overheat and fail. Higher temperatures and higher concentrations of additives will hasten mineral deposits

The Chiller can accommodate a variety of coolant fluids (water, glycol mixtures, etc). For most applications above 20°C (68°F), distilled water is satisfactory. For operation below 20°C (68°F), the Chiller must be protected with an antifreeze solution. Ethylene glycol (laboratory grade) and water in a 50/50 mixture is satisfactory from +20° to -15°C (68° to 5°F). Select a fluid that is compatible with the Chiller’s wetted parts (brass, bronze, stainless steel, EPDM rubber, nylon, PVC).

WARNING: Operation below 20°C (68°F) requires antifreeze in the circulation fluid. Do not use automotive antifreeze as the additives may be harmful to the Chiller's wetted parts.

110-392 12

Electrical Power

WARNING:

Do not plug unit into the electrical outlet until it is ready for startup.

Always turn the unit OFF and disconnect mains power before performing any maintenance or service as hazardous voltages exist within chassis components.

WARNING: DO NOT apply power until the unit is ready for Startup.

Connect the power cord (if) supplied with the Chiller to an appropriate electrical outlet.

Phase Requirements (if applicable)

For 3-phase units, be sure to connect in proper sequence, ie.: L1, L2, and L3. These Chillers are designed with a junction box on the rear of the unit to which you can connect the electrical power supply conduit. Be sure to provide suitable conduit strain relief and grounding.

3-phase units are equipped with a phase monitor that prevents startup if phase sequence is incorrect. The Chiller will turn OFF in the event of a loss of one phase and/or prevent operation if there is a voltage mismatch between any two phases greater than 8%.

Optional Signal Inputs/Outputs

Ambient / External Temperature Probe

Allows control of the cooling fluid temperature using an external temperature measurement (ambient room/machine temperature or process temperature). A 9-pin connector is provided for connecting the ambient/external tracking probe.

NOTE: In order for the Chiller to properly recognize the presence of the external temperature probe, the probe must be connected to the unit before power is applied..

RS-232 / RS-485 Serial Output

Allows remote control the Chiller and/or the output of temperature readings to an external auxiliary device. The maximum communications distance for Chillers equipped with the RS232 option is 50 feet (15 meters). The maximum distance for units equipped with the RS485 option is 4000 feet (1200 meters). A 9-pin D-connector is provided for this connection.

Remote On / Off Port

Allows the connection of a remote On/Off switch or other remote control device to the Chiller. A 15-pin Dconnector is provided on the rear of the instrument enclosure for this connection.

4-20mA Set Point Control

Allows set point changes using a customer supplied current value. A 15-pin D-connector or 8-pin circular connector is provided for this connection.

110-392 13

Startup

Facility Water Flow (water-cooled units only)

1. Open the valves to the facility water supply and return.

2. Check for leaks.

Filling the Reservoir

1. Remove the reservoir cap located on the top of the Chiller and, using a funnel, add fluid until it is approximately 2 inches (5.1 cm) below top of reservoir.

2. Once the fluid level is about 2 inches (5.1 cm) below the top of the reservoir, remove the funnel but do not replace the cap at this time.

Starting Process Fluid Flow

1. Place the circuit breaker located on the rear panel of the Chiller to the ON position. The display on the front

working electrical power and that circuit breaker on the rear of the Chiller is in the ON position.

2. Press the Power Button on the front panel. The system startup sequence will begin and proceed as follows:

• The pump will turn on and fluid will begin circulating through the system.

• The set point temperature will appear briefly on the Temperature Display; after a few seconds, it will be

replaced by the actual fluid temperature.

• 15 to 20 seconds after power up, the compressor will begin operating.

NOTE: When adding fluid to the unit for the first time, prime the pump by pressing the Power Button to turn

power ON, letting the Chiller run for 3 seconds, and the pressing the Power Button again to turn power OFF. Repeat this ON and OFF procedure three times.

3. Check for leaks.

4. With the pump running, the reservoir’s fluid level will drop as the process and/or process cooling lines fill with fluid. Slowly add fluid to the reservoir until the liquid level remains stable.

5. Replace the reservoir cap.

110-392 14

Normal Operation

NOTE: The Chiller incorporates a special "lockout" feature that can be enabled to prevent unauthorized or

accidental set point and other operational changes. This feature is described in detail under "Enabling and Disabling the Local Lockout." It should not be enabled until all operational parameters have been set.

Selecting the Temperature Unit (°C or °F)

Adjusting the High Pressure Bypass Setting

Locknut

Chillers with a positive displacement or turbine pump incorporate an automatic safety to maintain outlet pressure below a valve-regulated pressure. This valve is adjustable and is located inside the Chiller housing.

WARNING: Service should only be performed by fully qualified personnel. Extreme caution is required as hazards are present when servicing this equipment.

To access the high-pressure bypass valve, remove the access panel on the top of the unit (rear left).

The high-pressure bypass is adjusted as follows:

1. Set the low flow rate alarm value to zero (see Setting Operational Parameters, Minimum Flow Rate). This will

prevent the unit from activating the flow alarm while you are adjusting the maximum pressure setting.

2. Completely block the Chiller’s outlet flow. This should cause the outlet pressure to rise.

3. Set the Pressure/Flow Rate Display to read either PSI or kPa.

4. Rotate the handle on the pressure valve until the desired maximum

pressure setting is shown on the Pressure/Flow Rate Display.

5. Secure the Locknut.

6. Reset the flow alarm value to the previous setting.

7. Return the Pressure/Flow Rate Display to the previous setting.

8. Replace the access panel.

Enabling / Disabling the Local Lockout

This feature is used to prevent unauthorized or accidental changes to set point and other operational values. When enabled, the values for the following functions can be displayed, but not changed:

• Temperature unit

Routine Maintenance

The Chiller is designed to require a minimum of periodic maintenance.

Condenser, Air Vents and Reusable Filter

The condenser, the air vents, and reusable filter should be kept free of dust and dirt. They should be checked on a regular basis and cleaned as required.

The reusable filter is accessed from either the left or right side of the unit. Use a mild detergent and water solution to wash off any accumulated dust and dirt. Rinse and dry thoroughly before reinstalling.

Inline Strainer

An inline strainer with 20 mesh stainless steel screen is located on the inlet to the heat exchanger. To access, remove the Chiller’s top cover (attached at the rear of the unit with two screws). Remove the threaded cap, pull the screen out of the fitting, rinse off any particulate material, and reinstall. Be sure to check for leaks after reinstalling.

Fluid Level

The fluid level should be periodically checked to determine if the fluid level needs to be topped off. Generally, fluid should be added whenever the level in the reservoir is 2 inches (5.1 cm) below the top of the reservoir.

NOTE: On units equipped with the heater option, check fluid level when operating at maximum temperature and allow for fluid expansion. Use of a venting assembly (see “Controls and Components”) is recommended.

Cleaning

Only mild detergents and water or an approved cleaner should be used on the painted and stainless steel surfaces of the Chiller. Do not allow cleaning liquids or sprays to enter the Controller vents.

RS-232 / RS-485 Communications

Serial Connector — A 9-pin D-connector (optional) is provided on the back panel of the Chiller for RS232 / RS485 data communication. A serial cable that uses only the following pins should be used to connect the Chiller to the computer:

RS-232 RS-485

Pin # 2 data read (data from computer) Pin # 3 DAT (+) on “B”

Pin # 3 data transmit (data to computer) Pin # 5 signal ground

Pin # 5 signal ground Pin # 9 DAT (-) on “A”

RS-232 / RS-485 Protocol — The controller uses the following RS-232 / RS-485 protocol:

Data bits — 8 Parity — none Stop bits — 1 Flow control — none Baud rate — selectable (Chiller and PC baud rates must match).

Communications Commands — Commands must be entered in the exact format shown. Do not send a [LF] (line feed) after the [CR] (carriage return). Be sure to follow character case exactly. A question mark (?) indicates that the Chiller could not execute the command (either because it was in an improper format or the values were outside the allowable range). A response followed by an exclamation point (!) indicates that a command was executed correctly. A response must be received from the Chiller before another command can be sent. All responses are terminated with a single [CR].

This feature is optional and may not appear in your version of the software.

NOTE: Two versions are available. If the model number of your Chiller contains an N in the 11

digit (e.g., 6860T56A26ND), it provides 4-20mA set point control over a temperature range of 5° to 90°C; if the 11th digit is an K, the 4-20mA control range is 4° to 40°C

Go to menu item “CC” and set to “YES”.

If current input is outside of the range of the 4–20 mA, “Ft 18” will be displayed.
