This article covers the complete installation and initial startup sequence for the BrewBlast™ 110CPH nitrogen generator. Complete all steps in order before placing the system into service. Only qualified technicians should perform installation.
Pre-Installation Requirements
- Install indoors only, in a well-ventilated room with normal air exchange to the surrounding space.
- Ambient temperature must remain between 40–90°F during operation.
- Maintain at least 6" of clear space on each side of the cabinet to allow adequate airflow through the ventilation openings. Blocking the vents will cause heat to build inside the cabinet.
- The unit ships on lockable swivel casters. Position the unit in its final location before making any connections, then lock all four casters.
- Do not place or stack anything on top of the cabinet.
Step 1 — Electrical Connection
Connect the power cord supplied with the BrewBlast™ 110CPH to the port labeled Power Supply on the rear of the cabinet. Plug the opposite end into a standard 120VAC / 60Hz / 1-phase wall receptacle. A dedicated small appliance circuit is preferred.
Customer Alarm Wiring (optional)
The rear panel includes a 3-wire customer alarm port for remote monitoring via an audible alarm, visual indicator, or building management system. For wiring details, terminal functions, and contact ratings, see BrewBlast™ 110CPH – Specifications & Components. Follow all local and site wiring regulations when making these connections.
Step 2 — Nitrogen Outlet Connection
The nitrogen outlet is a standard industrial quick coupler located on the rear panel, labeled Nitrogen Out. A 1/4" MNPT quick coupler plug is included for connection to 1/4" NPT hoses and piping.
To connect:
- Pull back the sleeve on the nitrogen outlet quick coupler.
- Insert the quick coupler plug fully into the coupler body.
- Release the sleeve — it will spring forward and lock the plug in place.
- Tug the connection gently to confirm it is seated and locked before pressurizing.
Step 3 — Condensate Drain Connection
The condensate drain is a 1/4" OD push-to-connect bulkhead fitting located on the rear of the cabinet. Connect 1/4" OD tubing and route it to a suitable floor drain or collection point. The filter bowls drain automatically when sufficient condensate accumulates — the external tubing prevents water from pooling on the floor.
Step 4 — Initial Startup
- Confirm all electrical and plumbing connections are complete and all downstream valves are open.
- Push the green illuminated toggle switch on the front panel to the ON (up) position.
- The toggle switch will illuminate, indicating the system is powered. The compressor will start after a 12-second delay — this is normal and protects the compressor on startup.
- Allow the system to run and begin filling the internal storage tank. Monitor the 0–160 PSIG pressure gauge on the front panel.
- Purge the downstream plumbing — including all hoses and lines leading to the cold brew or beverage system — with the generated nitrogen for at least 15 minutes before placing the system into service. This ensures the lines are filled with high-purity nitrogen rather than residual air.
- While the system is pressurizing, inspect all connections for leaks. Listen for audible hissing and check fittings by hand or with an approved leak detection solution on non-electrical components.
- Once the storage tank reaches approximately 90 PSIG, the generator will shut off automatically and the amber standby light will illuminate. This is normal operation.
- As nitrogen is consumed downstream, the tank pressure will drop. When it falls to approximately 60 PSIG, the generator will restart automatically and refill the tank.
Normal System Operation
The BrewBlast™ 110CPH operates in two automatic modes once powered on. The internal controller determines which mode to enter based on storage tank pressure.
| Mode | Indicator | Description |
|---|---|---|
| Run | Amber light off | Generator is running, compressor is active, and the storage tank is being filled with nitrogen |
| Standby | Amber light on | Storage tank is full (~90 PSIG); generator is idle and will restart automatically when tank pressure drops to ~60 PSIG |
The system is designed for 24-hour operation. Ensure that proper downstream regulators, cooler temperatures, and line temperatures are maintained for consistent pour performance.
Starting and Stopping
For routine daily use, the unit does not need to be powered down. The system will cycle between run and standby automatically.
- To start: push the green toggle switch to the ON (up) position. The compressor will start after the 12-second startup delay.
- To stop: push the green toggle switch to the OFF (down) position.
