The flat part of the thin round plate should be between screw heads. Remove product pick up tubes from the product containers. Note: Static mixer is inside the nozzle. If static mixer is lost, the product will not mix properly. (See Figure F.) 3. Turn the dispensing nozzle upside down and remove static mixer. Repeat the same with all remaining nozzles. 4. Wash the parts with water mixed with hand dishwashing detergent. 5. Rinse all parts thoroughly, put static mixers into nozzle leg first and install them back in the machine by inserting into mixing chambers and locking in positions. Failing to lock in position may cause dispensing nozzle with the static mixer to be pushed rapidly out of the mixing chamber by the 29 Psig (2 bar) water Note: Wash on a regular basis the drip tray and the drip tray grill separately. (see figure G) Sanitizing and Cleaning Dispensing System Product Pumps System Cleaning The product pumps system cleaning assures the performance of the pumping system and cleans the inside walls of tubing. The product used is very thick (6+1 concentration or more) and will build up a layer of sucrose and pulp mixture on the inside walls of tubing. This build up narrows the inside diameter of the tubes and will restrict the product flow and will slowly offset the brix. Proper cleaning of the pump system will help prevent and correct this condition. 1. Remove the product containers from the dispensing cabinet. Replace each container with any clean container (same capacity as product container) filled with warm water (40-45°C) and insert product pick up tubes (Figure F) - - - - (Figure G) pressure and splash all surrounding with mixed product. Replace product pick up tubes. (Figure H) Page 8 Crathco® Post Mix Beverage Dispensers into clean container. (see figure H) 2. Close the cabinet door and dispense the warm water the same way, as it would be a product. Dispensing should last for no longer than 90 seconds. 3. Repeat the above for all remaining dispensing stations. Washing Parts Proceed as described in “Wash Parts” without flushing. Sanitizing Prepare sanitizing solution per instruction on the package changing the strength of the solution to be equivalent to 6+1 e.g. If instruction calls to dilute contents of the sanitizer package in 4 liters of water use only 0.6 liters of the water for the solution. Fill the clean container that was used for tubing cleaning with the sanitizing solution. 1. Install container with sanitizer solution in the cabinet and connect pump tubing to product pick up tube assembly. 2. Close the cabinet door and depress dispensing switch corresponding with position of the container with sanitizing solution for 15 seconds. 3. Wait 3 minutes. 4. Lift the pick up tubes assembly to be above the sanitizing solution and depress the same dispensing switch for 2 seconds to avoid sanitizer spillage inside of the cabinet. Rinse the pick up tube assembly and connect it back to the pump tubing. 5. Replace the container containing the sanitizing solution with the product container. 6. Depress dispensing switch. Keep dispensing product until 200 ml is dispensed with correct brix. 7. Repeat steps 1 to 6 for all remaining stations. 8. Turn the flush switch to FLUSH and depress each dispensing switch for 4 seconds. Note: Do not skip any sanitizing procedure step. Flushing (Figure I) Proceed as described in Flushing the Dispensing System. Flushing time is only 4 seconds. Preventing Unauthorized Dispensing During “Off Hours” After system flushing, do not turn the flush switch to the DISPENSE position. Lock the door and remove the key from the lock. This will allow dispensing cold water only. (See figure I) Note: Turn the flush switch to DISPENSE when resuming operation the next day.

Biweekly: Sanitizing (See page 8-9). Ice bank water level check up. (See figure J) Note: Make sure that water level in the drain tube is even with tank overflow outlet. Monthly: 1. Check the condenser for dust build up. If necessary clean the condenser with a bristle brush. 2. After sanitizing, remove dispensing base assembly and wipe off the interior of the cabinet with a cloth dampened in sanitizer. 3. Check the platform of the dispensing base assembly and clean it using sanitizer solution. Replace dispensing base assembly. 4. Clean cabinet cooling system drain with a small bottle brush and sanitizer solution. 5. Check water level to ensure it is maintained at aproper fill level (See page 4). Filling the ice bank with water. Every half of the year: 1. Replace all pump tubing. If pumps are loosing their capacity and adjusting pump speed does not correct the problem, replace tubing on a more frequent basis. 2. Remove cabi...
