I. Unboxing Inspection and Pre-Installation Preparation (Must-do for beginners to avoid rework)

1.1 Check Factory Standard Accessories
After unboxing the Share Cool FS2-3F, please verify each item against the packing list to ensure no missing, deformed, or transport-damaged parts. Core standard accessories include:

Share Cool FS2-3F three-valve countertop cola machine main unit

Base bracket, 4-to-3 adapter, water inlet filter (with cartridge, gasket, special wrench)

Food-grade air tube, 3 syrup tubes (one for each valve head), water inlet tube

Gas cylinder wrench, small screwdriver, sealing gaskets, spare screws

Product manual, product certificate, warranty card

1.2 Pre-installation Operations
Before installation, pre-route the 3 syrup tubes through the reserved holes in the base, straighten the tubes to ensure no kinks or pinching, so they can be quickly connected to the Share Cool FS2-3F main unit and syrup bags later, avoiding misalignment during installation.

1.3 Required Tools and Installation Environment Requirements

Required tools: Factory-supplied gas cylinder wrench, filter-specific wrench, 14-inch adjustable wrench, Phillips screwdriver

Installation environment standards:

The Share Cool FS2-3F must be placed on a flat, hard countertop. Leave at least 10cm of ventilation space behind the unit, matching the main unit dimensions 400680780mm.

Provide a nearby grounded 220V three-prong outlet and a 4-point water inlet ball valve. Distance between water source and unit ≤2 meters.

Keep away from heat sources, open flames, and direct sunlight. Reserve dedicated spaces for upright gas cylinder and flat-lying syrup bags.

II. Dual-Mode Water System Installation (Share Cool FS2-3F factory standard, zero mistakes for beginners)

The Share Cool FS2-3F supports both tap water and bottled water modes. Choose the appropriate procedure based on your store’s actual situation. Mixing the two modes is strictly prohibited.

2.1 Tap Water Mode Installation Steps

Connector and filter preparation: Use the 4-to-3 adapter with built-in sealing gasket to connect firmly to the water source ball valve. Remove the plastic protective film from the filter cartridge, rinse it with clean water to remove loose fibers, then install into the filter housing. Press the gasket into place. Ensure the round hole in the filter cap aligns perfectly with the cartridge hole. Hand-tighten, then use the filter-specific wrench to tighten in reverse direction until fully sealed.

Tubing connection rules: The filter housing is clearly marked “IN” and “OUT”. Follow the water flow direction strictly: connect one end of the independent water tube to the water inlet ball valve (tighten to prevent detachment), and the other end to the filter inlet. Connect the filter outlet tube to the water inlet on the back of the Share Cool FS2-3F. Before turning on water, double-check that all connections are fully inserted and gaskets are in place.

Water flow test: Slowly open the water inlet ball valve. Check all connections for leaks. No seepage or dripping means success. If leaks occur, turn off the water source, reconnect the fittings, replace sealing gaskets, and test again until satisfactory.

2.2 Bottled Water Mode Installation Steps

Use a food-grade purified water container of at least 20L capacity. The container opening must be smooth and undamaged.

Cut the Share Cool FS2-3F water inlet tube at an angle in advance. Insert it vertically to the bottom of the container to prevent the tube from sticking to the wall and causing pump failure.

Ensure no kinks or floating sections. Protect the container opening from dust to avoid water contamination.

III. Gas System Installation and Pressure Adjustment (Safety core, get it right the first time)

3.1 Gas Cylinder and Gauge Installation Steps

Before installing the gas cylinder, confirm that the sealing gasket at the cylinder mouth is intact and not loose. Align the gauge with the cylinder mouth, hand-tighten first, then use the factory-supplied gas cylinder wrench to tighten further in reverse direction.

After the air tube is in place, use the 14-inch adjustable wrench to clamp and secure it. Adjust the gauge orientation for easy reading, and avoid bending the tube.

3.2 Rated Pressure Adjustment Standard
Use the factory-supplied adjustment rod to set the pressure. Rotate the rod slowly clockwise to adjust the pressure to the normal rated value of 70-80 psi. The gauge needle must be in the middle of the green zone. Never exceed 100 psi. After adjustment, tighten the lock nut to secure the pressure value and prevent drift during operation.

3.3 Airtightness Pressure Hold Test Requirements
After adjusting pressure, close the gas cylinder valve and perform a pressure hold test lasting 10-15 minutes. Do not operate the Share Cool FS2-3F during this period. If both pressure gauges show no drop, the system is airtight. If pressure drops, it indicates a leak at the gas line connections (cylinder-to-gauge or gauge-to-machine). Re-tighten connections, replace gaskets, and test again until passing.

IV. Syrup System Connection and Flavor Label Management (Three valves, prevent cross-contamination)

The Share Cool FS2-3F comes standard with 3 syrup tubes, one for each valve head (angle valves). There is no fixed order; you can connect them according to your store’s flavor plan.

Tube connection operation: Pinch the white connector at the tube end, then screw the black quick-connect thread onto the syrup bag’s fitting. The natural seepage of syrup indicates a proper seal. Ensure the connection is tight and leak-free.

Each supplied syrup bag has a triangular opening mark. During installation, the triangular opening must face downward. The outer carton of the syrup bag can be used as a support base and stacked.

After all syrup tubes are connected, attach corresponding flavor labels to avoid wrong connections that would cause flavor mixing.

V. Filling the Tank and Powering On (Warranty red line – never run dry)

5.1 Standard Tank Filling Procedure

Core requirement: You must fill the water tank before connecting power to start the Share Cool FS2-3F. Never run the unit dry, as this will damage the equipment and void the warranty.

Tap water mode filling: First turn off the water source. Press the ring on the water filling port to retract the internal teeth, then remove the tube and fill with water until it reaches the overflow hole (this unit has no external drain pipe; overflow goes directly into the drip tray). After filling, immediately turn off the water source and reattach the tube.

Bottled water mode filling: Use a measuring cup to add water through the filling port. Fill until water reaches the overflow hole.

5.2 Power-On and Accessory Installation
After confirming that the tank is filled and all water/gas seal tests have passed, plug the power cord into a properly grounded three-prong outlet. Turn on the main switch. Observe that the unit operates without abnormal noise and the display panel works normally. The unit’s lightbox mounting plate is secured to the body by two small holes. If the threads are loose during installation, wrap Teflon tape around them to increase friction and ensure a firm, wobble-free mount.

VI. Post-Installation Commissioning and Taste Calibration (30 minutes, ready for operation)

After first power-on, wait 8-10 minutes for the water tank temperature to drop to the factory-set range of 1-5°C, then proceed with dispensing tests.

Press each valve head’s dispense button one by one to purge air from the lines until continuous liquid flow without bubbles is achieved. Verify that each valve dispenses smoothly with no clogging or leaking.

Taste calibration: Use the syrup adjustment valve on the back of the Share Cool FS2-3F to adjust the syrup-to-carbonated water ratio. Turn clockwise to increase syrup, counterclockwise to decrease. Adjust until the taste meets your store’s target profile.

Dispense 10 consecutive cups. Verify that the unit dispenses stably, with temperature fluctuation ≤0.5°C and no taste degradation, meeting the factory dispensing standard of 120-150 cups/hour during peak hours. Then the unit is ready for normal store operation.

VII. Quick Troubleshooting for Share Cool FS2-3F Installation (For beginners to avoid pitfalls)

Symptom: No pressure rise after power-on
Main inspection direction: Gas cylinder not opened, pressure not reaching rated value, gas line seal failure
Quick fix: Check that the gas cylinder valve is fully open. Readjust pressure to 70-80 psi. Re-tighten all gas connections, replace sealing gaskets, and retest.

Symptom: Syrup not rising, no syrup output
Main inspection direction: Syrup quick-connect not tightened, syrup bag placed incorrectly, tube kinked or pinched
Quick fix: Re-tighten the connection until syrup naturally seeps out. Place syrup bag with triangular opening facing down, flat. Straighten tubes and check for kinks.

Symptom: Gas but no water
Main inspection direction: Water source interrupted, water inlet tube not fully inserted
Quick fix: For tap water mode, check that the inlet ball valve is open. For bottled water mode, verify that the inlet tube is inserted vertically to the bottom without kinks; then restart the unit.

Symptom: Bottled water mode fails to draw water
Main inspection direction: Inlet tube end stuck to container wall, tube not below water surface
Quick fix: Pre-cut the inlet tube at an angle. Adjust tube position to avoid wall contact or surfacing.

Symptom: No carbonation in dispensed drink
Main inspection direction: Low gas pressure, water tank temperature not reached, gas leak
Quick fix: Readjust pressure to 70-80 psi. Wait for tank temperature to drop to 1-5°C. Perform the airtightness pressure hold test again to locate leaks.

IX. Installation Red Line Rules and Warranty Statement

The entire installation process for the Share Cool FS2-3F must strictly follow the logical sequence: Water → Gas → Syrup → Fill Tank → Power On. Do not reverse any steps. Failure of any single seal will prevent the unit from operating properly.

All connections (ball valve, filter, gas cylinder, syrup tubes) rely solely on physical tightening for sealing. No glue or welding is required. During installation, ensure gaskets are intact, threads are properly engaged, and wrenches are used with sufficient force. Never install without gaskets.

The procedures for filling, purging, and starting up differ significantly between bottled water mode and tap water mode. You must follow the correct procedure for your actual water source. Mixing the two modes is forbidden.

Never modify the unit’s tubing or electrical circuit without authorization. Never replace seals, filter cartridges, valve heads, or other core parts with non-original components. Violating these rules will void the warranty.
