Glykool 130 Service Programme

The new Glykool range of glycol coolers have been designed to be reliable and

simple to operate. The coolers have been designed to offer a technical solution

to the growing demand for colder and colder dispensed products; this is best

achieved by the use of sub-zero glycol.

The Glykool coolers use well-known and well-proven mechanical refrigeration

technology but also encompass a number of technical changes, which will

enhance both the performance, and reliability of this system.

Refrigerant flow around the system is controlled via a thermostatic expansion

valve that allows the system to react to changes in required capacity under a

wider range of operating parameters

This cooler underwent a number of thorough quality checks before leaving the

factory to ensure the minimum number of faults occur during the life. However,

to ensure this cooler can meet the demands it has been designed for it must be

installed and maintained in accordance with the manufactures guidelines.

These can be found later in this booklet, which must remain with the unit at all

times.

INSTALLATION

On installation, a number of important rules must be observed to be sure the

cooler operates correctly. These will be found under the heading

(INSTALLATION GUIDE), which covers both water-cooled and integral

models.

Glykool130

a) INSTALLATION GUIDE

INTEGRAL UNITS

1. Ensure the cooler is installed in a well-ventilated location with no obstructions to the

condenser or side and rear panel ventilation slots. The unit must not be installed in an area

where it will be exposed to temperatures that are likely to cause freezing, (i.e. below 0°C)

or are in excess of 32°C.

2. Ensure the unit is installed on a level surface and is filled to the overflow, with cold

water/glycol below 24°C. Glycol/Water mixture should be 50%.

3. Dose water tank with Kleencare SP920 in accordance with instructions supplied with the

Kleencare kit, and taking note of heath & safety sheets.

4. Ensure all tubing connections to the product coils and re-circulation pump are well

insulated with Armaflex type insulation to prevent condensation.

5. Ensure that the python run is not excessive, and is routed away from external heat

sources. Maximum lift is 10m, Maximum run 50m.

WATER COOLED UNITS

1. Ensure the cooler base is installed in a well-ventilated location with no obstructions to the

side and rear panel ventilation slots. The unit must not be installed in an area where it will

be exposed to temperatures that are likely to cause freezing, (i.e. below 0°C) or are in

excess of 32°C.

2. Ensure the unit is installed on a level surface and is filled to the overflow, with cold

water/glycol below 24°C. Glycol/Water mixture should be 50%.

3. Ensure that the header tank is filled to its maximum level with the correct ratio of

water/glycol coolant mix (30%) to prevent freezing of the tubes connecting the heat dump

to the base unit, which can be exposed to sub zero temperatures. (See Glycol

Requirement Chart).

4. Before switching on the unit, turn the line clean switch to the off position to enable the

glycol lines to be fully primed. Once this is complete, turn the switch to the on position.

5. Ensure that the coolant re-circulation pump and tubing connecting the heat dump are

primed with coolant, that there are no air locks or restrictions and that coolant is freely

returning into the header tank. Top up the header tank to maximum level after priming.

6. The header tank level must be regularly checked and maintained with the correct ratio of

water glycol mix (30%)

7. Ensure all tubing connections to the product coils and re-circulation pump are well

insulated with Armaflex

8. Ensure that the python run is not excessive, and is routed away from external heat

sources. Maximum lift is 10m, Maximum run 50m.

9. All water cooled units are fitting with a auto reset thermal switch to protect the compressor

should the glycol level drop, the heat dump become blocked, or the glycol pump fail.

Note:

The electronic control is fitted with a delay on power up.

The delay allows the control to self-check.

HEAT DUMP - GENERAL GUIDELINES

1. It is important that the heat dump is sited correctly to enable it to work efficiently. The

guidelines below should be adhered to wherever possible.

2. Ensure the unit is sited on an outside wall (preferably non-south facing) in the correct

orientation out of direct sunlight.

3. Ensure there are no other heat sources, i.e. a condensing unit or another heat dump, in

the immediate vicinity, where hot air may be re-circulating.

4. Use the recommended tubing (15mm O/D, 10mm I/D Special EVA) to connect the base

unit to the heat dump. Do not use PVC braided tube, as this is not compatible with glycol

and will degrade over a period of time.

5. Do not exceed the recommended distance and lift from the base unit to the heat dump of

10M Lift / 50M Run.

6. The heat dump must be connected using a minimum of 1.5mm two core cable. If a smaller

cable is used, a voltage drop will occur which may cause the fan motor to run at a reduced

speed.

7. If the unit is to be installed inside a building or room, ensure that there is adequate

ventilation within the room to enable the heat to be dissipated effectively. Temperatures

within the room should not exceed 32°C.

8. Do not kink the flow and return tubes, which would restrict the coolant flow.

9. Do not insulate the flow and return lines.

10. The flow and return lines must not be strapped together, as heat transfer between the two

will affect the system performance.

11. Ensure that the heat exchanger matrix of the heat dump is kept clean and free from

obstructions. It is recommended that it should be cleaned with a soft brush at regular

intervals (see maintenance schedule).

12. To enable the heat dump to be mounted on a flat surface, a floor standing mounting kit is

available as an option. (Order part number 09-0203-01)

For details on use and mounting refer to installation instructions in section h

b) INSTALLATION INSTRUCTIONS.

NOTE: The unit should be installed and serviced by a suitably trained person.

NOTE: Sealed plugs may be fitted to new units.
