To set up the EemaX AUTOBOOSTER for first-time use, follow these steps:

1. Shut Off Electricity – Turn off the electricity at your circuit breaker before starting any installation steps.
2. Check Clearance – Ensure there is at least 14 inches of straight pipe clearance above the tank heater for proper installation.
3. Close Water Supply Valve – Shut off the supply water valve to the tank heater, usually located above the tank on the cold water inlet side.
4. Drain the Tank – Open the drain valve, typically near the bottom of the tank, to fully deplete the water from the tank.
5. Drain Hot Water Pipes – Remove any remaining water from all existing hot water pipes.

These steps prepare the system for installation and ensure proper operation.
