The System Product overview A range of draught beer dispense glycol cooling systems delivering consistently cold temperatures (between 2oC and 4oC) from a minimum of one dispense point in the CRYO 10 AU to a maximum of 14 dispense points in the CRYO 90 AF/100 WF. The system utilises a CRYO system cooler containing a sub zero coolant. Product is cooled in coils which are immersed in the sub zero coolant.
Location continued Floor mounted CRYO WF coolers The CRYO WF coolers 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 CRYO WF coolers in the temperature controlled product store. The CRYO WF coolers should not be exposed to liquid spillage, spray, steam or high humidity.
CRYO WF and Discharge Cooler Warning, this appliance must be earthed! Caution, avoid spilling the glycol mix, wipe excess glycol away as it is slippery! Installation must only be carried out by a suitably trained person and comply with national and local codes for connection to electrical supply. It is recommended that the mains electrical supply is protected by an RCCB.
Glycol Lines/Wiring (CRYO WF units only) Using a minimum 1.5mm2 two core cable for a maximum 50m run, connect the Discharge Cooler to the CRYO WF cooler. Connect the two core cable to the bottom two pins on the plug. The plug socket is located at the rear of the CRYO WF cooler (Note: This is a nominal 24 volt supply). Complete the glycol circuit by connecting the pipe work between the CRYO WF cooler and the discharge cooler with the aid of the fittings provided.
CRYOCOOL Installation Check list These sheets are intended as a guide to a method of installation of the CRYOCOOL System.
Bar Installation 1 Site coolers (CRYO AU only) 2 Run python into position in bar 3 Pull out product lines from python close to and beneath relevant font re-taping as you go 4 Fit flow control to product lines (not supplied) keeping 3/8 pipe to minimum between flow control and python 5 Connect restrictor tube between flow controls and taps. Tape and insulate 6 Fit trace cooling tees into python as required and insulate 7 Fit Pressure Balancing valve between flow and return.
Commissioning The CRYO coolers will cool glycol to a sub zero temperature- DO NOT TOUCH. Before switching the CRYO AU, AF & 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 set range of temperatures. Ensure products dispensed at between 2°C and 4°C.
Maintenance (Faults/Repairs) • • • There are no user serviceable items inside the equipment. Maintenance must only be carried out by a properly qualified and trained person. Switch off the mains supply and unplug the equipment if it malfunctions or receives any physical damage causing it to become unsafe and/or working outside the parameters set in this document. User Maintenance • • • • • Switch off and unplug the unit during maintenance operations. Do not remove any protective covers.

Glycol Glycol Freezing Points A 30/70 mix of Glycol/Water has a freezing point at around -14ºC (Refer to Graph 1) Graph 1.
Glycol Mix Brix A 30/70 mix of Glycol/Water has a sugar percentage (Brix) of around 20% (Refer to Graph 2) Graph 2.
Refractometer Usage Instructions for the use of the hand refractometer for measuring Glycol/Water Concentrations Calibration • Flip open the daylight plate, which covers the prism. • Apply one or two drops of clean tap water onto the prism, using a soft applicator, such as a cable tie. • Close the daylight plate. • Holding the refractometer up to the light, look at the scale through the eyepiece, turning the eyepiece assembly until the boundary line, created by the water, is in sharp focus.
