Glykool 130+ Service Programme
The 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 product; this
is best achieved by the use of sub-zero glycol.
The Glykool cooler use well-known and well-proven mechanical refrigeration
technology, but also encompasses 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 capillary tube that
optimises the capacity of the unit under certain operating parameters.
This cooler underwent a number of through quality checks before leaving the
factory to ensure the minimum number of faults occur during its life. However,
to ensure that this cooler can meet the demands it has been designed for, it
must be installed and maintained in accordance with the manufacturers
guidelines. This information can be found later in this booklet, which must
remain with the unit at all times.

Glykool 130+ Installation Guide
On installation, a number of important rules must be observed to be sure the
cooler operates correctly.
• 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 (below 0°C) in excess of 32°C
• Ensure the unit is installed on a level surface and is filled to the
overflow, with a 50% glycol/cold water mix below 24°C.
• Dose the water tank with Kleencare SP920 in accordance with
instructions supplied with the Kleencare kit, taking note of the health
and safety data sheets provided.
• Ensure the header tank is filled to the maximum level with a 30%
glycol/cold water mix to prevent freezing of the tubes connecting the
heat dump to the base unit, which may be exposed to sub-zero
temperatures (See Glycol Requirement Chart)
• 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.
• 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 the coolant is freely returning to the header tank.
Top up the header tank to the maximum level after priming.
• The header tank level must be regularly checked and maintained with
the correct ratio of 30% glycol/water mix.
• Ensure that all the tubing connections to the product coils and
recirculation pump are well insulated with Armaflex.
• Ensure that the python run is not excessive and is routed away from
external heat sources. Maximum lift is 10 m. Maximum run is 50 m.
Notes:
All water cooled units are fitted with an auto reset thermal switch to protect the
compressor should the glycol level drop, the heat dump become blocked or
the glycol pump fail.
The electronic control is fitted with a delay on the power up. The delay allows
for the control to self-check

Heat Dump General Guidelines
• 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.
• Ensure the unit is sited on an outside wall (preferably non-south facing)
in the correct orientation out of direct sunlight.
• 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.
• 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.
• Do not exceed the recommended distance and lift from the base unit to
the heat dump of 10 m lift / 50 m run.
• 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.
• 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.
• Do not kink the flow and return tubes, which would restrict the coolant
flow.
• Do not insulate the flow and return lines.
• The flow and return lines must not be strapped together, as heat
transfer between the two will affect the system performance.
• 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).
• 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 of the heat dump, refer to installation
instructions on page 24.

Prevention of Freezing
Unit Freezing
It is recommended that the unit be sited in such a way as not to expose it to
temperatures likely to cause freezing. If the unit is to be sited in an unheated
area, it would be wise to the insulate all the pipe work and provide some form
of emergency heating, which should be controlled by a frost-stat and sited in
close proximity to the unit.
In the event of freezing up occurring, the following action is recommended:
• Isolate unit form the mains electricity supply
• Isolated product supply from unit
• Apply gentle warmth to the general area of the unit and its pipe work
• Check for obvious leaks
• Turn on water supply whilst continually watching for leaks
• Reconnect product supply
• Reconnect mains electricity supply
• Observe unit running for a short period watching out for leaks, strange
noises and the any other form of malfunction
• If no problems are observed, then normal operation of the unit may be
resumed.
Product Freezing
A product freeze up will only occur if the line clean procedure is not followed.
In the event of a product freeze up, the following procedure should be
followed:
• Switch the line clean to the ON position.
• Allow the unit to run in ‘line clean’ mode for one hour.
• Check to see if the lines are still frozen by opening the dispense tap.
• If no flow is observed from the dispense tap, the unit should remain in
‘line clean’ mode for another hour before checking the dispense tap
again for flow.
• When flow is observed from the dispense tap, switch the line clean to
the OFF position.

Glycol Concentrations
Food grade mono propylene glycol should only be used with this unit. The
freeze point of glycol depends on the concentration of glycol to clean water
mixture. If insufficient concentrations of glycol are used, the system may
freeze.
Glycol Concentration for Glycol Bath
It is recommended that a 50% glycol / 50% clean water mix is used for the
glycol bath. This will protect a system down to –15°C and below
Glycol Concentration for Heat Dumps
A 30% glycol / 70% clean water mix will protect the system down to –13°C.
The amount of glycol required for the heat dump, Add 2.5 pints (1.4 Litres) for
the glycol tank to the length of pipe work as shown in the following table:
