Galaxy Aqua Premier Installation Manual [exclusive]

The Galaxy Aqua Premier is an instantaneous electric water heater/shower designed for mains cold water connection. Installation must strictly follow electrical (IEE) and water regulations. 🛠️ Installation Requirements

Water Supply: Connect only to the cold water main (not a tank unless a booster pump is used). Pressure & Flow: Minimum Pressure: 1.0 Bar (15 psi).

Minimum Flow: 8–11 litres per minute, depending on the kW rating (e.g., 9L/min for 9.5kW).

Electrical: Requires a dedicated 230/240V AC supply with its own fuse and a double-pole isolation switch.

Pipework: Uses 15mm copper or stainless steel pipe. Do not use jointing compound; use PTFE tape if needed. 📋 Installation Sequence

Mounting: Fix the unit to a flat wall away from direct spray.

Plumbing First: Complete all water connections before any electrical work. galaxy aqua premier installation manual

Flushing: Flush the supply pipe thoroughly to remove debris before connecting to the unit.

Electrics: Connect Live, Neutral, and Earth (must be earthed) to the terminal block.

Commissioning: Run water through the unit before switching on the power to avoid "dry firing" the elements. ⚠️ Critical Safety Tips

Freeze Warning: Never install the unit where it might freeze.

Ventilation: The outlet acts as a vent; do not fit any taps or flow controls to the shower outlet.

Check Valve: Fit a double-check valve if the shower head can reach into the bath or tray water. 🔧 Common Troubleshooting I have a galaxy aqua-premier andcthe thermalcut out keeps The Galaxy Aqua Premier is an instantaneous electric

In the quiet, tile-walled sanctuary of a suburban bathroom, Arthur sat on the edge of the tub, staring at the glossy white box in his hands: the Galaxy Aqua Premier

. It wasn't just a shower; it was a promise of instantaneous heat, a 9.5kW marvel designed to replace the old, sputtering unit that had finally given up the ghost.

Beside him lay the Galaxy Aqua Premier Installation Manual, its pages crisp and smelling of fresh ink. Arthur knew that for a successful "premiere," he had to follow the script exactly. Act I: The Preparation

The manual's first commandment was absolute: Safety First. Arthur marched to the consumer unit and flipped the breaker, ensuring the power was dead. He then turned the main water valve until it wouldn't budge. He wasn't just installing a fixture; he was managing a delicate dance between high-voltage electricity and pressurized water. Act II: The Anatomy of Installation

Arthur opened the front cover, removing the two screws that held the control knobs in place. Inside, the unit revealed its secrets—the terminal block for the 240V supply and the 15mm inlet for the cold water.

Marking the Territory: He held the backplate against the wall, away from the direct spray of the handset. With a pencil, he marked the drilling points, careful to avoid the hidden pipes and cables lurking behind the tiles. Stage 5: Loading the Filters Refer to the

The Plumbing: He connected the 15mm copper pipe to the inlet elbow. "No jointing compound," the manual whispered—only PTFE tape if things got difficult. Before the final connection, he flushed the pipe to clear out debris that could clog the internal filters.

The Wiring: Arthur threaded the heavy-duty cable through the unit’s entry point. He stripped the wires, ensuring the earth cable was sleeved in green and yellow. He tightened the terminal screws until they were "VERY TIGHT"—metal to metal, no insulation trapped—knowing that a loose connection was an invitation to overheating. Act III: The Final Alignment

With the internals secure, Arthur performed the "Calibration Ritual." He rotated the temperature spindle fully anti-clockwise to the cold setting and aligned the power selector to the '9 o’clock' position. The front cover clicked into place, and the screws were driven home. The Grand Finale

Arthur didn't flip the power yet. He turned on the water first, letting it flow through the unit for several minutes to purge every last bubble of air—a critical step to prevent the heating elements from burning out instantly. Installation and User Guide

Stage 5: Loading the Filters

Refer to the filter layout diagram in your Galaxy Aqua Premier manual: Usually Left to Right.

  1. Sediment Filter (Stage 1): Usually white or spun polypropylene. Remove the blue wrench, unscrew the left sump, drop the filter in, and screw the sump back on (hand-tight + 1/8 turn).
  2. Carbon Filter (Stage 2): Usually granular activated carbon (GAC). Rinse it slightly under tap water to flush carbon fines. Install in the middle housing.
  3. RO Membrane (Stage 3): This is the "heart."
    • Unscrew the horizontal housing.
    • Lubricate the O-ring (with silicone grease, not petroleum).
    • Push the membrane firmly into the socket until it seats.
    • Screw the cap back on.
  4. Polishing Filter (Stage 4): The final inline carbon filter (often a small horizontal canister). Connect one end to the manifold and the other to the faucet tube.

Safety Precautions Not to Overlook
