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

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.

Section 2

HEAT DUMP INSTALLATION

INSTRUCTIONS

NOTE: The unit should be installed and

serviced by a suitably trained person.

Installation Guide

Unpack the unit from its transportation

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.

With cover assemby

fully open, lift o

Removable Wall

Mounting Bracket

adequate clearance is allowed around the heat

dump to allow future access for cleaning.

Note - 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  tted.

Either mark the position of the third mounting

screw at the time of marking the wall mounting

bracket position, or after  tting the wall

mounting bracket hang the condenser matrix on,

close against the mounting surface and mark the

 xing position.

Note - the third  xing screw will pass through

the hole in the condenser matrix. The retaining

clamp is  tted over the screw, which can then

be tightened to retain the condenser matrix.

Fitting

Remove the wall mounting bracket from the assembly, (mounted on lift o hinges).

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.

Tighten the strain relief grommet to
