What affects shower performance?
The shower unit's top priority is to keep the desired water temperature constant.
To maintain this temperature, the shower may have to automatically change the
rate of water owing through the unit. Any of the following conditions can cause the
shower to change the ow rate (force of the shower) in order to keep the temperature
constant. Most changes are minor and will go unnoticed.

General Notes
This product works best when supply temperatures and pressures remain
stable and within the product specications, refer to section "Specications".
If the supply conditions fall outside the specications, the shower may go into
a safe shut down condition.
1. Plumbing Do's & Don'ts
Refer to section: "Important Safety Information" rst.
1.1 Do not use sealing compounds on any pipe ttings or joints.
1.2 Never t the unit to hot water supplies or to gravity systems of any
description. Only t the product to a mains cold water pipe.
1.3 Avoid layouts where the shower hose will be sharply kinked. This may reduce
the life of the hose.
1.4 Supply pipework MUST be ushed to clear debris before connecting the
appliance. Debris will reduce the performance of the unit.
Avoid running the pipework through excessively hot or cold areas such as hot
loft spaces, airing cupboards, or in close proximity to hot water pipes. If this
cannot be avoided, we would recommend insulating the pipes.
1.5 The appliance must be tted onto the nished wall surface i.e. on top of the
tiles. DO NOT tile up to the sides of the unit or use a sealant around the
case. Failure to do this may cause product failure.
1.6 We recommend that a non-restrictive (free owing) isolating valve is tted in
the cold water supply pipe to allow maintenance of the appliance.
1.7 When installed in very hard water areas (above 200 ppm temporary
hardness) your installer may advise the installation of a water treatment
device, to reduce the effects of limescale formation.Any malfunction due to
limescale is not covered by the manufacturer's guarantee. Your local water
company will be able to advise the hardness of water in your area.
1.8 Caution! Double checkvalves, tted in the inlet supply to the appliance,
cause a pressure buildup, which could exceed the maximum static inlet
pressure for the appliance.
2. Electrical
Refer to section: "Important Safety Information" rst.
2.1 In a domestic installation, the rating of the electricity supplier’s fuse and the
consumer unit must be adequate for the additional demand. All Mira Advance
ATL electric showers are high power units. Voltage drop due to local heavy
demand will reduce the shower’s performance.
INSTALLATION REQUIREMENTS

11
2.2 The appliance must be earthed by connecting the supply-cable earth
conductor to the earth terminal.
Any supplementary bonding and supply cable size must conform to BS 7671.
2.3 As a guide only, and in accordance with BS 7671 we recommend close
circuit protection:
I.e. 9.0 kW = 40 Amp
9.8 kW = 45 Amp
A separate, permanently connected supply is taken from the consumer unit
to the appliance through a double-pole switch. The switch can be a ceiling
mounted pullcord type or a wall mounted switch in an adjacent room.
2.4 DO NOT exert strain on the terminal block, however make sure that the
electrical connections are tightly screwed down.
2.5 DO NOT turn on the electrical supply until the plumbing has been completed.

COMMISSIONING
Important! The Mira Advance ATL will adapt it's settings for the individual supply
conditions and store this information in it's main memory (during manufacture, this
informationisfactorysetusingidealconditions).Oninitialinstallation,theunit needs
to "learn" about the site conditions and does so during the commissioning cycle.
It is important that the unit is commissioned correctly otherwise an error condition
may occur. Once set, the unit constantly updates it's memory with information about
the site conditions to optimize the shower's performance. This is stored once the
Start/Stop button is pressed whilst the shower is running.
Basic Operation Checks
1. Switch on the electrical supply at the
mains and test the Shower Drain Pump
(if applicable, see separate Shower Drain
Pump instructions) before turning the
shower on. Switch on the electrical supply
at the double-pole switch. The Start/Stop
button will illuminate to indicate that the
electrical supply is connected to the
shower.
2. Turn the Temperature control dial to full
cold, the dial operates anticlockwise from
hot to cold.
3. Push the Flow or Start/Stop button and
observe the blue ow indicator with audible
beep. Check that cold water ows freely
from the shower within a few seconds.
If a delay of more than 5 seconds is
encountered, then it is likely that the unit
has not been primed.
Refer to section "Installation" for priming
the unit using the air bleed button. Should
the unit still not function then refer to the
section "Fault Diagnosis".
After a short delay, the Shower Drain Pump (if applicable) should operate and
drain the waste water, after the shower is turned on.
Adjusting Maximum Temperature Limit and Commissioning Cycle
4. Make sure the double pole switch is off.
5. Set the Temperature control dial to the position required for the correct
temperature as shown in the following table.
6. Switch on the double pole switch and check the blue Start/Stop button is lit.
Flow
Start/Stop

17
7. Within 30 seconds, push and hold down the Flow and Start/Stop buttons at
the same time.
8. On the long beep, release the Start/Stop button. On the short beep, release
the Flow button.
Following the Maximum Temperature Setting procedure, the appliance
automatically starts a Commissioning process to check and adjust to the site
conditions. The High Flow light ashes for approximately 2 minutes. Caution!
During this cycle the water temperature will reach a maximum of 44 °C.At the
end the Flow light goes off, the shower stops and goes to the normal standby mode.
The maximum temperature limit can be further reset to any temperature within the
table by repeating this process. The shower is now ready for use.
If the unit's maximum temperature is set to 41 °C or cooler, there is a clear triple
beep tone and single flash of the Start/Stop light when double pole switch is turned
back on. This is to show that the unit is in a "BEAB Care" compliant mode. If
recommissioningis requiredwhilstinthismode,waituntilbeepshavepassedbefore
starting the commissioning cycle.
Memory model: ifthe maximum temperatureisadjustedafter havingbeenstoredin
one or more of the memory buttons, then the showering temperature cannot exceed
the new maximum setting.
E.g.
Note! High cold water mains supply pressures and high shower temperatures will
cause a slight audible hissing sound to be heard from the unit whilst it is operating.
This is quite normal and does not indicate that there is a fault with the unit.

1. How your Shower Works
1.1 Hot water is produced by passing cold water through
a heating tank.
The unit constantly monitors the following conditions:
• The incoming cold water temperature.
• The outgoing shower temperature.
• The ow rate of water.
• The current user settings.
The ow rate may automatically adjust to maintain
the current temperature setting. As part of this
process, a series of "clicks" may be heard, this is a
normal part of the operation when the shower is in
use.
The showering temperature is adjusted by turning the Temperature Control Dial,
which varies the ow of cold water passing over the elements. The slower the rate
of ow, the warmer the shower and vice versa.
