COOLING UNIT MARKS AND CARACTERISTICS
Every cooling unit has its own identification number/code. This number is on the
plate/label “technical data”. Plate/label with technical data is the only way to
identify cooling unit; consists all necessary data about unit which are relevant to
the user/service people for quick and simple identification.

EN Instalation
35
The main porpuse of this glycol cooling unit is to cover heat losses when beer
is transfered from beer cooling unit to dispensing tap. When there is no
dispensing on the taps, beer which is in the tubing
between beer cooling unit and dispensing taps would
become warm. Glycol cooling unit cools down beer in
tubing so beer is cold even after few hours of no-
dispensing.
Most of technical issues can be easily solved by simple procedures. To this purpose we
ask you to read instructions carefully before informing service people or
manufacturer. In case you cannot solve the problem by using instructions from this
manual, please contact the seller from which you bought the unit. Keep units
in good condition and do not allow any modification on it except if they are
approved by the producer.
WORKING PRINCIPLE
AMBIENT CONDITIONS FOR INSTALLATION
PROCEDURE IN CASE OF MALFUNCTION
Cooling unit has to be installed in the place where it is protected from rain, water
sparkles, with temperature correspondent to its climate class (marked on label
Technical data); in case this terms are not assured warranty is no longer valid and
malfunctions in performance are possible.
Possible climate classes are:
SN – temperature of environment from 50°C to 90°F
N – temperature of environment from 61°C to 90°F
ST – temperature of environment from 65°C to 100°F
T – temperature of environment from 65°C to 110°F
Instalation
In accordance with current regulation, installation and setting has to be
done by authorized and proper technical stuff.
INSTALLATION
Where is maximum allowed incline 2 degrees. During the installation of the cooling
unit with air cooling it is necessary to ensure that there is enough space needed. Unit
is need to be placed on straight and translucent space, far from heat source, away
from wall 11,8 inch and 11,8 inch from next unit. It is need that air circulation around
the unit is assured.
Cooling unit has to be placed correctly on the surface:

INSTALATION STEPS
1. Connect one of the glycol tubes to the pump inlet. Insulate any exposed tubing.
2. Connect the second glycol line to the pump outlet. Insulate any exposed tubing.
3. Remove filling hatch to fill the bath with liquid.
4. Inspect the bath for debris.
5. Fill the glycol bath with Micro Matic Polar Flo glycol solution (mixed 2 ½ parts
water to 1 part glycol) Fill the bath to the full level on the glycol level indicator.
6. Connect unit to the electrical outlets capable of handling the required voltage
loads. This should be carried out by suitably trained personnel and comply with all
state and national electrical codes.
7. Glycol level will fall as glycol is pumped through the glycol lines. Continue to fill
the bath to the fill level on the glycol level indicator..
8. Inspect for any leaks.
9. Glycol temperature will fall slowly to 29°F.

Maintenance
MAINTENANCE
CHANGING A GLYCOL PUMP
1. Unplug unit from receptacle.
2. Remove four (4) screws holding pump to bath lid.
3. Cut tubing slightly above outlet fitting on pump.
4. Remove pump through hole in top of bath lid.
5. Insert new pump through opening in lid.
6. Attach pump outlet hose and clamp with stainless steel clamp.
7. Replace mounting screws and plug unit into receptacle.
1. Inspect the unit monthly to ensure that the glycol level is maintained to the full
level.
2. If the level is low replace with a Micro Matic Polar Flo glycol solution: mixed 2 ½
parts water to 1 part.
3. If there is evidence of ice build up in the unit, allow the ice to melt and replace
all the water/glycol solution with a fresh solution mixed per above instructions.
4. The glycol/water solution should be changed approximately every 18 months. In
regions of high humidity considerations should be given to replacing the solution
on an annual basis.
5. Check and clean the condenser fins every sixty (60) days.
6. Check that there is adequate air flow through the unit ensuring
enough space all around and that there are
no obstructions in front of the air flow vents.
7. Check the condition and effectiveness of
the trunk line insulation.
8. At regular intervals, to be determined by
the owner, the unit should be checked for
electrical saftey.

packing shows that the product after end of the life cycle must be separated from
other waste, and that is related to the usage of the electric and electronic
equipment and properly waste disposal. Separated collection and recycling this
kind of the equipment helps to avoid possible negative influence on the
environment and health, and also helps to use again or recycle some of the
materials that were used to set the equipment. Unauthorized disposal of this type
of the product includes possibility to apply the legal penalties in accordance with
current legal regulations.
