Installation Manual

Preparation

The plumbing installation must be completed before the electrical installation.
The minimum income water pressure to activate the appliance is 1.0 mca (1.5 Psi or 10 kPA or 0.10 Bar) (Fig.:01).
The maximum income water pressure is 40 mca (58Psi or 400kPa or 4Bar). Residential plumbing systems with unstable pressure or pressure above than recommended require the installation of a pressure stabilizer valve.
Before installing the appliance, let the water run out to drain out all plumbing dirt and to purge out any air bubbles/pockets and make sure there are no leaks.

Water quality and pressure may have an impact on the lifespan of the heating element, as well as on the appliance. These factors are not be covered under the manufacturer's warranty.
The inlet water nipple comes with an income water pressure regulator device (Fig.:02). Do not remove the device -subject to warranty loss.
The water outlet (1/2” BSP thread) must be flat level to the wall. If it’s too deep inside the wall (over than 3mm), install an extension device (does not come with the product). (Fig.:03).

Place PTFE (Teflon) tape around the nipple thread (Fig.:02).
Screw the appliance gently at the water outlet thread. Do not use tools (Fig.:04)
The appliance needs to be correctly aligned and horizontally leveled (Fig.: 04).

Spreader Installation

Align the spreader with the body and push it until it couples with the duct (Fig.:05).
Identify the dot mark on the body, approach to it and align with the dash mark on the spreader (Fig.:06).
Push the spreader until it touches the body.
Rotate the spreader clockwise, latching it (Fig.:07).

Warning: Before connecting it to the cables, in order to prevent the burning of the heating element, open the shower tap to run water through and to fill up the inner heater chamber. Check for any water leakage and shut the shower tap off.
Repeat this operation whenever the product is removed and reinstalled.

Installation and Usage

Install the hose holder on the wall in a way that it does not block the water flowing through it, and at a height easily by hands reach. Note: Check the pipes position into the wall to ensure they won’t be drilled during the hose holder installation (Fig.08).
How to use the hand shower: Push and pull (open and close) the center pin of the hand shower (Fig.:09).
Close the hand shower after use.
In case of no install of the hose and hand shower, place the hose plug to shut the water outlet (Fig.08).

Warning

In order to prevent the risk of electric shocks, make sure to connect the grounding wire of the appliance (green or green/yellow cable) to the grounding system.
The electrical installation and grounding system of this appliance shall be performed by qualified people. Do not use the neutral wire for grounding.

Never attempt to install, disassemble, inspect or repair the appliance before disconnecting the power on the main electric switchboard (Fig.11).
External Cleaning: Use only damp cloth without any chemical.
Internal cleaning of the spreader: Hardness (high mineral content), dirt and debris in the water can affect the well-functioning of the appliance. If there is obstruction of the spreader holes causing reduction of water flow and/or deforming jets, it is recommended to clean the spreader.
For spreader cleaning: remove by turning it counterclockwise and follow the steps indicated at Figs.16 and 17. Then, proceed as in Fig.15. Use a brush to unblock the holes. After cleaning, reinstall the spreader back as instructed at Item 4.1 (Spreader Installation) to the heater unit. Run water through the appliance, making sure there are no leaks and the water is flowing uniformly and unobstructed through the spreader. Then, turn the circuit breaker ON.

Preparing

The connection of this appliance is compatible with the residual current circuit breaker (RCD or RCCB).
Make sure the voltage of the appliance is compatible to the voltage of the electric supply (127V~ or 220V~) (Fig.10).
Run dedicated and adequate cable/wires from also dedicated and adequate circuit breaker on the main switchboard to the appliance (Fig.11).
Such installation should take into consideration the voltage (V), power rating (W) and distance from the appliance to the main switchboard, by following its requirements on the technical characteristics table.
Never attempt to install, disassemble, inspect or repair the appliance without shutting off all power to the unit by means of the exclusive circuit breaker on the main electric switchboard.
