What you need between delivery and the system sitting in its place, including where our supply ends and your site begins.
Installation must be done by someone familiar with hydrogen safety, electrical safety and alkaline electrolyte handling. Read the safety chapter first.

First timeStart with unpacking and incoming inspection on the day it arrives. Reading the site and battery-limit sections before delivery makes the preparation quicker.
Done this beforeThe site conditions and the battery-limits table are all you need.

Unpacking and inspection
Where it goes
- Surface or rack
- A stable, level surface or a 19-inch 6U rack. It must support at least 100 kg, counting the unit plus hoses and cables.
- Front clearance
- At least 300 mm, so you can connect and disconnect tubing, plug in power and Ethernet, see the LED and reach the power switch.
- Rear clearance
- At least 400 mm. Do not block the rear exhaust airflow.
- Ambient temperature
- 5–45 °C
- Ventilation
- Indoors, well ventilated. Not in a sealed room or a small unventilated enclosure.
- Ceiling
- Hydrogen is lighter than air and collects high up. Avoid covered ceiling spaces where it can accumulate.
- Discharge points
- Decide where O2 OUT, H2 OUT and H2 VENT each discharge safely before you start.
- Hydrogen detection
- If your site risk assessment calls for it, fit a detector and put alarm and response procedures in place.
Before installation
Battery limits
What is inside the one box and what belongs to your site. When you review a quotation, line it up against this boundary first.
- Inside the unit
- The stack, the electrolyte tank and circulation pump, the heat exchanger, the heater, power conversion, control and instrumentation, and the safety interlocks. You do not have to assemble a separate balance of plant.
- Upstream is yours
- The DI water supply, making up and storing electrolyte, the incoming power and breaker, and earthing.
- Downstream is yours too
- Vent and exhaust routing, the dryer, compression and storage, the connection to the point of use, and whatever overpressure protection the code requires.
- Who repairs what
- Repair and replacement of site equipment is the customer's responsibility. We interpret the alarms and operating trends to judge the system's behaviour and tell you whether factory service is needed.
