3 The System Product overview A retail account based glycol cooling system delivering consistently cold temperatures (between 2 o C and 4 o C) across a maximum of ten dispense points per CRYO 100 WF remote cooler. The system utilises a CRYO 100 WF remote cooler containing a sub zero coolant. Product is cooled in coils which are immersed in the sub zero coolant. The cooled product temperature is maintained by using a super chill python installed between the CRYO 100 WF remote cooler and the dispense point. Benefits Reduced power consumption Replaces the requirement for both remote and shelf ice bank coolers. Additional space underneath the bar for storage of glassware. Reduced heat input to the bar area. Configuration Product stored at a maximum of 13 o C in a temperature controlled cellar is supplied to the product coils in the CRYO 100 WF remote cooler by a standard dispense panel. A super chill python, made using 12 x 3/8 product lines, 2 x 15mm OD recirculation lines and covered with 19mm insulation is connected to the product coil outlets and recirculation pump flow and return. When using a 14 line super chill python connect only the 12 lines which are wrapped within the 19mm insulation, the other 2 are built in for redundancy purposes and should not be used, drinks will be out of specification if they are. The glycol mix in the CRYO 100 WF remote cooler s coolant bath is pumped around the super chill python to maintain the temperature of the product between the cooler and the point of dispense. Trace cooling is allowed using a T piece fitted to the recirculation flow line allowing the glycol to circulate around the trace cooling loop and return into another T piece fitted in the recirculation return line. Survey General considerations The purpose of the survey is to determine in advance of the installation whether special considerations need to be raised with the design company or the main contractors. Items to be considered are: Location of the CRYO 100 WF remote cooler is the location suitable? Is there a suitable electrical supply within 2 metres of the chosen location? The standard super chill python has 12 lines. If the existing python has more than twelve lines, a second python will be required. Can the existing route to the bar area accommodate an additional python? Will the cooler interfere with existing services or storage facilities? Better to ask the manager first! Routes between bars? New bar layouts may have a raised step to house pythons and cables. Where bars are simply refurbished there may not be sufficient room in existing channels. Contractors need to know if there will be additional work. Can the install be made to allow minimum down time of the dispense system? 3

4 Survey cont. System constraints The main constraints of the system will be the pumping capacity of the vertically-mounted CRYO 100 WF pump. It is desirable to ensure that the maximum distance between the coolers and the pressure differential valve is 40 metres. Beyond this distance, cooling performance may be affected due to the reduction in glycol flow; however 60 meters can be achieved by installing an optional boost pump. The pump priming height (head) is more than sufficient for most installations, including where the cooled cellar is below ground. Cooler location The CRYO 100 WF may be sited within cooled cellars, store rooms or other appropriate internal areas where the ambient air temperature will not exceed 40 C, however when used in the CRYOCOOL system it is better to site the cooler in the temperature controlled product store. A suitable position should be chosen within 2 metres of a 13A socket. The CRYO 100 WF uses conventional remote heat dumps to remove waste heat from the refrigeration unit. The heat dumps can be sited up to 50 metres from the coolers, preferably discharging to an external ambient. The electrical connections between CRYO 100 WF cooler and heat dump must be made with suitable 1.5mm 2 cable and 15mm O.D tubing, with a sufficient bore to ensure a minimum flow in this circuit of 4.5litres/minute. Installation CRYO 100 WF and Discharge Cooler Locate CRYO 100 WF in selected position (within 2 metres of a 13A socket) Fill the top tank with glycol and water (mixed at 30% glycol, 70% water). The top tank should be filled with this glycol mix to just above the top of the evaporator coil. Select a suitable position to site the discharge cooler and fit as normal. The CRYO 100 WF can be run with the unit switched to clean mode (cools to approximately 2 C) and the top mounted pump disconnected, to ensure the integrity of the discharge cooler circuit. CRYO 100 WF Product line connections From the sub zero python connect the recirculation lines to the flow and return of the top mounted recirculation pump on the CRYO 100 WF. From the dispense panel in the temperature controlled cellar connect the product lines to the inlet of the product coils of the CRYO 100 WF. Connect product lines of the super chill python to the outlet of the product coils of the CRYO 100 WF. te: All lines to be well insulated! Bypass Valve At a convenient point immediately after the furthest dispense tower from the cooler, the pre-insulated bypass valve needs to be fitted to ensure suitable differential pressure is maintained between the flow and return lines. Connect the valve between the flow and return lines, ensuring the arrow on the valve is pointing in the direction of the return manifold. Connections between python insulation and the valve can be sealed using PVC tape and/or Armaflex tape. See installation checklist below 4

5 Installation cont. Trace Cooling To allow trace cooling, a T piece is fitted in the recirculation flow line allowing the glycol to circulate around the trace cooling loop and return into another T piece fitted in the recirculation return line. To encourage flow through the trace cooling loop a pressure bypass valve is fitted between the flow and return at the end of the super chill python; this creates a pressure difference of approximately 10psi between the recirculation flow and return. The trace cooling flow rate is adjusted using a flow regulator located in the return trace cooling line before it re-enters the T piece in the return python line. A nominal flow rate of 1 litre/minute (adjusted when commissioning) ensures adequate cooling under most conditions. te: Where capillary tube is less than 0.75m long and where the 9.5mm beer line is terminated close to the python exit point, trace cooling may be omitted. For all other instances trace cooling will be required.

7 Commissioning Before switching the CRYO 100 WF to cool mode ensure that all coils are purged with product! Commissioning can only be successfully completed when: Recirculation pump is running and all components are installed and connected Glycol bath temperature remains between 2 C & 4 C Ensure products dispense at between 2 C and 4 C. te: The temperature controller on the CRYO 100 WF does not require any alteration during set up, it is factory set to the parameters required. Trace cooling Begin with setting the trace cooling flow on each trace cooling loop. Turn the knurled knob on the flow adjustment valve 1.5 turns anticlockwise from fully closed. This will give approximately 1 litre/minute, which is sufficient for maintaining cooled product in the lines. If temperatures are consistently too cold it is possible to alter the sub zero glycol temperature via the temperature controller in the base of the CRYO 100 WF, however be aware, this will alter the temperature of the casual drink. Product Supply Cleaning lines All product lines should be sterilised using known procedures and cleaning chemicals. It is absolutely essential that all traces of water are removed from extra-cold product lines before commissioning begins. Failure to do this will result in frozen coils, and damage to the system may result. Suggest, to ensure the CRYO 100 WF is at the correct temperature to perform the cleaning operation switch to clean at the end of the evening and perform the cleaning operation the next day. Cleaning socket labels Cleaning reminder labels (supplied) should be installed adjacent to the extra-cold cleaning sockets in the cellar. In accounts where it is felt that the cleaning regime may be overlooked, additional labels (not supplied) can be fitted to the keg connectors. Final checks * Clean shelves of debris and discarded fluid (beer and/or glycol) * Check that all joints have been sealed against moisture ingress * Ensure there are no leaks under bar, coolers and discharge cooler * Replace any bar furniture including back-panels and shelves * Leave system information pack in a conspicuous position by the CRYO 100 WF * Discuss cleaning regime with Manager/cellar man thoroughly 7
