Vision V21 & V34 Service Programme
The Vision range of remote coolers have been
designed to combine in one unit a cooler that
can be used as a standard ice bank cooler, with
the options of modifying the programmable
control to enable the use as a glycol cooler.
This cooler underwent a number of thorough
quality checks before leaving the factory to ensure
the minimum number of faults occur during its
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
manufacturer’s guidelines. These can be found in
this booklet, which must remain with the unit at
all times.

Section 2
INSTALLATION GUIDE
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.
General
Unpack the unit from its transportation packing
and visually check for any signs of damage. Site
the unit in a convenient location as close to the
point of dispense as possible making sure that a
Mains Electricity Supply is within 2 metres and
allows easy access at all times. The area should
also allow free circulation of air around the unit.
The unit should be tted with a correctly fused
and wired 13 amp plug tted with a 10 amp fuse
or alternatively a standard Euro Plug to
IEC83: 1975.
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 which are likely to
cause freezing, (i.e. below 0 ºC ) or are in
excess of 32ºC.
2. Ensure the unit is installed on a level
surface and is lled to the over ow, with
cold water below 24ºC. Ideally ice should
be used to reduce the water bath temperature
to as low as possible , before switching the
unit on. The water level must be regularly
checked and maintained.
3. Dose water tank with an appropriate biocide
following the manufacturers instructions and
taking note of health and safety requirements.
4. Ensure all tubing connections to the product
coils and re-circulation pump connected to
the cooler correctly and are well insulated
with Arma ex 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 which are
likely to cause freezing, (i.e. be- low 0ºC ) or
are in excess of 32ºC.
2. Ensure the unit is installed on a level
surface and is lled to the over ow, with
cold water below 24ºC. The water level must
be checked and topped up once the python
lines have been primed.
3. Ensure that the header tank is lled 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
compressor isolate switch to the o 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 to the heat dump
is 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 (70%/30%)
7. Ensure all tubing connections to the
product coils and re-circulation pump are
connected to the cooler correctly and
are well insulated with Arma ex.
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 tting 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.
HEAT DUMP - GENERAL GUIDELINES
1. It is important that the heat dump is sited
correctly to enable it to work e ciently.
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. Power to the heat dump must be connected
using a minimum of 1.5mm
2
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 e ectively. Temperatures
within the room should not exceed 32ºC
8. Do not kink the ow and return tubes which
would restrict the coolant ow.
9. Do not insulate the ow and return lines.
10. The ow and return lines must not be
strapped together, as heat transfer between
the two will e ect 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 1a).
12. To enable the heat dump to be mounted
on a at surface, a oor standing
mounting kit is available as an option.

packaging and visually inspect for signs
of damage.
Site the dump in a convenient location,
preferably in a non-heat sensitive and
shaded area 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 from
the hot exhaust air from the heat dump.
In either situation the heat dump should
be sited to allow free circulation of air.
The maximum recommended height
of the heat dump above the cooler
is 10 meters.

Section 2
Connect the ow and return pipework from the
base unit to the ttings 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 ttings.
Note - Do not kink the pipework as this will
restrict coolant ow.
Do not insulate the pipework. (Pipework mounted
on an exterior surface may be insulated if it is felt
that due to extreme conditions freezing
may occur).
Do not strap the ow and return pipes together
as heat transfer between the two will e ect the
systems 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.
Note - The wires are not polarised and may be
tted 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.
