Below is the text version of "How to perform a chiller replacement". For a full version with photos please download the PDF using the link here or at the bottom of this article.
Overview
This article provides step-by-step instructions for field technicians when replacing a complete chiller in a Standup 1.5, 1.0, or 0.75 machine. Symptoms that may indicate the need for an entire chiller replacement include the following:
- Advised by Bevi to do so
- Water not chilled
- Water not carbonated
- Noise (either nonstop or occasional)
- Internal water leakage
- Excessive CO2 consumption
- Dispensing issue
Generally, the current recommendation is to replace the entire chiller when there is an internal failure. The complete chiller removal & replacement process takes approximately 30 minutes.
In this article:
- Task 1: Turn Off Water Source to the Bevi
- Task 2: Remove and Replace the chiller
- Task 3: Emptying the Chiller Tank
- Task 4: Fill the Ice Bank
Required Tools & Materials
- #3 Phillips Screwdriver
- Collapsible Bucket
- Booster pump (Part # 720-0006)
- 3/8” Push to Connect Stoppers
Task 1: Turn Off Water Source to the Bevi
- For all Standup units, follow the incoming water line and turn the manual valve so that it is in the closed position. The water line enters the back of the machine chassis.
Task 2: Remove and Replace the chiller
Standup 1.5 (front-connections chiller)
- Isolate the buffer tank by turning the manual valve to the closed position.
- Turn off the chiller by flipping the green switch on the side of the chiller, near the power cord.
- Close the valve on the CO2 tank.
- Unscrew the (2) screws that secure the foot clamp (chiller bracket) at the base of the chiller using a #3 Phillips screwdriver.
Note: Use the (2) threaded holes on the plumbing tray to secure the screws until needed again for installing the new chiller.
- Remove the foot clamp/chiller bracket and set aside.
- Using the service lines located on the side of the door, purge the sparkling water line and release the pressure from the still water line using the manual valves. When no water continues to drain, this step is done.
- Skip to Reference A steps below for instructions on how to empty the chiller (either with or without a pump) before continuing with the rest of the procedure.
- Remove the (5) red clips from the fittings located on the front of the chiller. Set aside for later use.
- Disconnect the tubing that is connected to these (5) fittings.
- Remove the (5) fittings and set aside.
- Plug exposed openings from the fittings.
- Disconnect the power plug from the chiller
- Remove the chiller from the unit.
- To re-install the chiller, perform steps 1-13 in reverse order, omitting the water line purges and emptying the chiller.
- Fill the ice bank following the instructions in Reference B below.
Standup 1.0, 0.75 (top-connections chiller)
- Turn off the chiller by flipping the power switch on the side
- Close the valve on the CO2 tank.
- Purge the sparkling water line by holding a bucket under the dispense nozzle and initiate a sparkling dispense on the touchscreen. Once no water is dispensing, the water line has been adequately purged.
- Release the pressure in the still water line by initiating a still dispense on the touchscreen. Keep the bucket under the dispense nozzle in case any water is eliminated from the tube.
- Close the two manual valves on the sparkling and still water lines that lead to the chiller.
- Remove the red clips and disconnect the valves, leaving them attached to the chiller.
- Skip to Reference A steps below for emptying the chiller before moving ahead with the following instructions.
- Pull the chiller out of the unit.
- Remove the power plug from the side of the chiller.
- Remove the IN WATER and IN CO2 tubes from the back of the unit.
- To re-install the chiller, perform steps 1-10 in reverse order, omitting the water line purges and emptying the chiller.
- Fill the ice bank following the instructions in Reference B below.
Reference A: Emptying the Chiller Tank
Standup 1.5 (front-connections chiller)
Emptying the chiller tank with a Pump
If emptying the chiller without a pump, skip to the next section below.
- Disconnect “fill/empty ice bank” water line from the front of the chiller.
- NOTE: Before turning the shutoff valve to the “open” position, make sure the tubing is pointing toward your bucket/sink.
- Turn the shutoff valve on the “fill/empty ice bank” water line to the “open” position. The chiller is empty when no more water is coming out.
- Insert tubing of pump into “fill/empty ice bank” push-to-connect fitting.
- Plug the pump into an electrical outlet, and turn on.
- NOTE: Before pumping, check to ensure arrows are aligned on the pump for proper directional flow. Additionally, check to see if the opposite end of the pump tubing is pointing toward the bucket/sink.
- Pump until completely empty.
Emptying the chiller tank Without a Pump
- With the chiller powered off, locate the recirculation jumper and disconnect the fittings from the chiller.
- Hold a bucket right underneath the fittings and turn the chiller on. Water should be now pumping into the bucket. Continue until no more water is coming out.
- Turn off the chiller and reconnect the recirculation jumper.
- NOTE: In some cases, the recirculation jumper may not be present and 3/8" stoppers will be in place.
Standup 1.0 (top-connections chiller)
Emptying the chiller tank with a Pump
If emptying the chiller without a pump, skip to the next section below.
- Remove the chiller to the point where you can access the protective cover located on the top front of the chiller that has (2) Phillips head screws located on either side.
- Remove the cover.
- Insert pump tubing into the chiller’s ice bank and ensure that tubing reaches the bottom of the chiller. Pump until completely empty.
- NOTE: Before pumping, check to ensure that arrows are aligned on the pump for proper directional flow. Additionally, check to see if the opposite end of the pump tubing is ready in bucket/sink.
Emptying the chiller tank Without a Pump
- With the chiller powered off, locate the recirculating line and disconnect them at the elbow connectors. The connection may be tucked and require extraction.
- Place the two lines coming from the chiller in the bucket and turn the chiller on. This will turn on the recirculating pump which will push water out of one of the lines into the bucket. Continue until no more water is coming out.
- Turn off the chiller when complete.
Reference B: Fill the Ice Bank
- Detach the overflow tube from the (2) securing clips.
- Place overflow tube in bucket
- Open water source valve to fill ice bank until water trickles into the bucket.
- Once water starts to fill the bucket, close the water source valve.
- Replace overflow tube in the securing clips on the front of the chiller.
