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).

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.

Installation

For safety reasons, the power supply/circuit breaker to the appliance must be disconnected or tripped off before any installation or maintenance.
Provide the installation of a junction box 13 cm above the water outlet (Fig.12).
Connect/splice the power cable/wire to the shower heater cable and make sure they are well tight and secure. Use adequate connectors or terminals (not included). Do not connect it by a plug and socket.

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.

Warning: Set the temperature selector (Fig.13) or ON/OFF button (Fig.14) to the OFF position. Open the shower tap to run water through and to fill up the inner heater chamber to prevent the burning of the heating element. Check for any water leakage and shut the shower tap off.
Turn the circuit breaker ON at the main switchboard where the appliance is connected to.

LOREN SHOWER ULTRA MULTITEMPERATURE
Place the temperature selector in any of the heating positions (Fig.13).
The shower turns on automatically when the shower tap is opened.
For your safety and longer life of the components, the temperature selector must only be moved when the shower tap is closed.

LOREN SHOWER ULTRA ELECTRONIC
Set the ON/OFF button to the ON position and turn the temperature-selector rod to any of the heating positions (Fig.14).
The shower turns on automatically when the shower tap is opened.
For your safety and longer life of the components, the ON/OFF button must only be moved when the shower tap is closed.
The temperature can be set by turning the rod while the appliance is running.
The water temperature can also be set by opening or closing the water flow at the shower tap.
Warning: This appliance can heat the water over than suitable for shower. Adjusting the water temperature on the appliance shall be taken to prevent the risk of scalding.

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.

PROBLEM	POSSIBLE REASON	SOLUTION
The water is not hot enough.	High water flow.	Reduce the flow rate via shower valve/tap.
	Very low temperature of the incoming water.
	Low setting temperature position.	Set the temperature selector at higher position.
	Electrical Installation Malfunction (voltage supply).	Contact a qualified technician/electrician to revise your electrical installation by checking the cables/wiring conditions (thickness) and voltage/amperage supply to the appliance.
The water is very hot.	Low water flow.	1) Increase the water flow rate via shower valve/tap or 2) Set the temperature selector at lower position
No water running.	Jet spreader blockage.	The jet spreader must be periodically cleaned to ensure no blockage occurred on holes.
	No water supply.	Check if the main and/or shower tap/valve are open.
	Air inside the pipe.	Disconnect the power and purge out any air bubbles/pockets
Water is cold or the appliance is not working.	Circuit Breaker or Shower are turned off.	Turn the breaker or the shower on.
	Off Position of the temperature selector.	Set the temperature selector at higher position.
	Burning of the heating element(*).	Replace the heating element.
The circuit breaker is tripping off.	Failing of the grounding system.	Fix the grounding system by consulting a qualified electrician.
	Electrical system overload.	Provide an exclusive and sized installation for the appliance.
Water drip after shut the shower tap off.	Natural flow of water stored inside the appliance after use.	At the end of the bath, close the shower tap, open the hand shower and let all the water run out. After this, shut the hand shower off.
	Dirty spreader with its hol es clogged.	Clean the spreader (Fig.15).
(*) 1) Wear due to normal use. Water quality impacts considerably on the element’s longevity. 2) Premature burning due to electrical installation malfunction or lack of water in the heating chamber (see previous solution chart). 3) None of the points above is warranty covered. The supply cord must not be replaced by the consumer. If the cord is damaged, take the appliance to technical service. Never attempt to install, disassemble, inspect or repair the appliance without first shutting off all power to the unit by means of the circuit breaker on the main electric switchboard.
