This document is the operator's manual for the Cornelius Impulse XL Post-mix Beverage Dispenser.
Function Description
The Impulse XL is an over-the-counter, post-mix beverage dispenser designed for large-cooling-capacity and ease of maintenance. It can be ordered with or without a built-in carbonator, and syrup pump kits are available. The unit dispenses carbonated and non-carbonated drinks by mixing syrup with plain or carbonated water at the dispensing valve. A CO2 cylinder supplies gas to syrup tanks or bag-in-box syrup pumps and to the integral carbonator. CO2 pressure pushes syrup through a cooling coil to the valve, and carbonated water (from the carbonator) is pushed through a manifold to the valve. For still drinks, plain water is substituted for carbonated water. The unit is factory-set to dispense non-carbonated and carbonated water as per customer requirements, and can dispense up to three non-carbonated waters, with remaining valves dispensing carbonated drinks. Non-carbonated water dispensing valves can be converted to dispense carbonated drinks.
Important Technical Specifications
Dimensions:
- Height: 27.6 inches (700 mm)
- Width: 18.3 inches (464 mm)
- Depth: 29.1 inches (740 mm)
- Shipping Weight (approx.): 176.2 pounds (80 kg, no water)
- Water Bath Size: 15 gal (US) (57 L)
- Ice Bank Size: 40.0 lb (18.0 kg)
Capacity (assuming 3 oz./sec. (85g/sec.) dispensing rate, 90°F (32°C) ambient temperature, two 12-oz. (340g) drinks per minute, and drinks dispensed at 40°F (5°C) or below):
- Raja unit, 230 volt, 50 Hz: 250 drinks continuously
Installation Requirements:
- Counter must be level and able to support 510 lbs. (200 kg).
- Environment: Indoor installation only, non-harsh environments.
- Ambient temperature: 50°F to 110°F (10°C - 43°C). Temperatures exceeding 110°F (43°C) will void the factory warranty and may lead to refrigeration system failure.
- CO2 pressure: 75 psi (5 bar) maximum.
- Syrup pressure: 60 psi (4 bar) maximum.
- Water pressure: 30-43 psi (2-3 bar) maximum. If water supply pressure is less than 40 psi, a booster is required; if more than 50 psi, a regulator is needed.
- Electrical: Refer to nameplate for specific requirements. A 10-amp disconnect switch (slow-blow fuse or equivalent HVAC/R circuit breaker) is required. For 50 Hz units, an ELCB (earth leakage circuit breaker) must be installed.
- Clearance: At least 8 inches (0.2 m) on all sides and 18 inches (0.45 m) on top to prevent overheating.
CO2 Regulator Settings:
- Bag-in-box applications: 70 psi (4.8 bar).
- Sugar base tank applications: 40 psi (2.8 bar).
- Diet base tank applications: 10 psi (0.7 bar).
- Colt dispenser with integral cold carbonator: 75 psi (5.2 bar). Higher CO2 pressure results in lower carbonation.
Electronic Control Board Functions:
- Ice bank control with compressor start-up protection.
- Carbonator control with continuous run protection (programmed timer shuts down pump motor if it runs continuously for more than 3 minutes to prevent water leaks or loss of water supply).
- LED diagnostics (Green LED for line voltage within range, Red LED for fault conditions like carbonator pump running over 3 minutes or compressor startup delay).
Usage Features
- Easy Maintenance: Removable refrigeration deck.
- Adjustable Flow Regulators: Water and syrup flow regulators on dispensing valves are easily accessible.
- Key-lock Switch: Activates valves and optional illuminated front merchandiser.
- Dispensing: Press a cup or glass against the lever or push the button on the valve cover.
- Syrup Supply Replenishment: Procedures for both tank systems and Bag-In-Box (BIB) systems are provided, including rinsing disconnects and connecting new syrup supplies.
- Water-to-Syrup Ratio Adjustment: Requires removal of the valve front cover and installation of a syrup diversion assembly. Carbonated water flow and syrup-to-water ratio can be adjusted.
- Flow Rates: Flow rates of water and syrup are adjusted based on the desired ratio (e.g., 5:1 ratio means water flow is 5 times syrup flow). A table of flow rates based on a 5:1 ratio is provided.
Maintenance Features
Daily Cleaning:
- Remove and clean cup rest, drip tray, valve nozzles, and diffusers with warm soapy water.
- Wipe down exterior surfaces.
- Pour warm soapy water down drains.
- Spray nozzles and diffusers with approved sanitizing solution.
Daily Maintenance:
- Check product temperature, smell, and taste.
- Check water pressure using gauges on the back room package.
- Check carbonation of the drink.
- Check CO2 supply level.
- Check dates on BIBs.
Monthly Cleaning (in addition to daily and weekly procedures):
- Flush and sanitize all syrup lines and connectors.
- Remove ice from hopper and clean/sanitize the hopper and cold plate surface using a provided brush.
Yearly Maintenance:
- Have water pump and check valve inspected and cleaned by a qualified service technician.
- Have CO2 gas check valve inspected and cleaned by a qualified service technician.
- Remove unit's splash and cold plate cover to clean and sanitize the cold plate surface.
Preventative Maintenance Summary:
- Sanitize Unit: Every 3 months.
- Check Ratio: Every 6 months, and whenever flavors are changed or service is performed.
- Clean Condenser: Every 6 months and as needed.
- Carbonator Double Liquid Check Valve: Annually.
- Check for Leaks: Annually.
- Clean BIB Connectors: Annually.
Troubleshooting:
- Detailed troubleshooting tables are provided for post-mix system issues (e.g., low syrup flow, low carbonation, foaming) and refrigeration system issues (e.g., compressor not operating, continuous operation without ice bank formation, agitator motor not operating).
- Carbonator troubleshooting table for pump not operating.
Component Service (requires qualified service personnel):
- Procedures for replacing Carbonator Pump, Pump Motor, Agitator Motor, Controller Board, Condenser Fan Motor, and Power Cord. These procedures involve disconnecting power, shutting off water and CO2, removing panels, and specific steps for each component.
- Warnings are provided for disconnecting power and depressurizing the system before service.
