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 re­circulating.

• 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 09­0203-01)

For details on use and mounting of the heat dump, refer to installation
instructions on page 24.

Portable Appliance Testing (PAT)

An additional test point has been fitted to the top of the rear panel of the unit
to provide a connection for PAT testing of the units on site. The tank drain
exits the unit via a 1/2 “ bulk head situated on the lower part of the left hand
panel. The shut-off valve can be accessed by removing the front lower grill.
Glycol flow and return connections are indicated by a coloured disc (red disc
for flow to the heat dump and blue for return from the heat dump).

Decommissioning of the glycol lines should be undertaken before
decommissioning of the 24V electrical socket in order to prevent the ingress of
glycol/water into the electrical socket.

Thermal Cut-Out

The unit is fitted with a thermal cut-out which will protect the refrigeration
system in the unlikely event of a fault in the glycol /heat dump system. The
thermal cut-out will isolate the power supply to the compressor if the heat of
the discharge lines increases above 65°C. The compressor will not cut back
in until the temperature in this line falls to below this temperature.

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:

Heat Dump Installation Instructions

This unit should be installed and serviced by a suitable trained person

Site the dump in a convenient location, preferably in a non-heat sensitive and
shaded location on the outside of the building. If it cannot be installed
outside, ensure that the area is free from other heat sources and is
adequately ventilated to prevent heat build up form the hot exhaust air from
the heat dump. In either situation, ensure that there is free air circulation
around the heat dump. The maximum height that the heat dump should be
above the cooler is 10 metres.

Fitting Instructions

• Unpack the unit from its transportation packaging and visually inspect
for signs of damage.

• Remove the wall-mounting bracket from the assembly, (mounted on lift
off hinges). Slacken the two fixing screws securing the cover/fan
assembly to the condenser matrix, swing the cover open and lift off the
assembly.

• With reference to drawing above, drill the surface onto which the heat
dump is to be fitted at the stated mounting hole centres ensuring that
adequate clearance is allowed around the heat dump to allow future
access for cleaning. The wall-mounting bracket can be used as a
guide for marking its hole centres. Ensure that the wall-mounting
bracket is mounted squarely to ensure level movement of the
condenser matrix when fitted.

• Either mark the position of the third mounting screw at the time of
marking the wall mounting bracket position, or after fitting the wall
mounting bracket hang the condenser matrix on, close against the

- 24 -

mounting surface and mark the fixing position. The third fixing screw
will pass through the hole in the condenser matrix. The retaining clamp
is fitted over the screw (as shown below), which can then be tightened
to retain the condenser matrix.

• Connect the flow and return pipe work from the base unit to the fittings
on the heat dump labelled “FLOW” and “RETURN” and secure the
pipes to the mounting surface so that the weight of the pipes is not
being carried on the heat dump fittings. Do not kink the pipe work, as
this will restrict coolant flow. Do not insulate the pipe work. (Pipe work
mounted on an exterior surface may be insulated if it is felt that due to
extreme conditions freezing may occur). Do not strap the flow and
return pipes together as heat transfer between the two will affect the
system’s performance.

• Route a twin core 24-volt supply cable through the lower guide tube
and then through the strain relief grommet positioned below the two
way terminal block on the condenser matrix. The wires are not
polarised and may be fitted either way round.

• Ensure that the amount of cable entering through the main cover is not
excessive and cannot become entangled in the fan blade. Tighten the
strain relief grommet to support the cable. This should not be the only
means of support for the cable, therefore fix back to the mounting
surface at regular intervals along the cable length.

• After the condenser matrix is fully fitted to the mounting surface, hang
the cover/fan assembly onto its hinges.

• With the cover/fan assembly open, connect the wires from the fan to
the terminal block. Ensure that the wiring from the fan is routed
through the plastic clip provided to prevent the possibility of the wires
becoming entangled in the fan blade (as shown on the next page)

- 25 -

Connect the wiring and the pipe work to the cooler following the instructions
supplied with the cooler.
