ASSEMBLY INSTRUCTIONS
General
MORA TEMP DUO - TWO MIXERSINONE!
• MoraTempDuoisacombinationofastandardkitchenorwashbasinmixerand
a sensor controlled tap. Using the lever the Mora Temp Duo works exactly as
any other ordinary mixer. But with the sensor function you get a non contact
function by holding your hands in front of the sensor eyes.
• When installing MoraTemp Duo in rooms where there is a periodic risk of
freezing, the fittings must be drained of water, otherwise there is a risk of the
tap being damaged through freezing.
• The control box must not be washed by high-pressure jet cleaning.
• The sensor part of the tap is fitted with automatic shut off after 24 seconds of
use (adjustable up to 48 sec). In order for the tap to start again the ”obstacle”
oryourhandsmustberemovedfrominfrontofthesensoreyesandthenmoved
back again. This is a safety feature to prevent flooding if an object were to be
placed in front of the sensor eyes.
• Before connection is made, the incoming water pipes must be flushed.
NOTE: If the red indication lamp is flashing or lights without the tap being used,
the battery voltage is too low, and the batteries must be replaced.
When the batteries have been removed and then replaced, the
RESET button on the circuit board must always be pressed in for a brief moment
to reset the electronics.
Spent products can always be sent to MORA ARMATUR AB
for recycling.
Assembly
1. Place the mixer in the hole, rec. hole dim 35mm (max 37mm - min 32mm),
and attach using the support washer and nut.
2. Remove the control cover, pull out the circuit board and make the neces-
sary changes to flush time and sensor distance. (see diagram A). Mount
the batteries, attach the sensor cable (the cable between the sensor eyes
and control box) on the circuit board, press the RESET button on the circuit
board and put back the cover. On AC operation: select AC instead of DC on
the circuit board, reset the transformer to 12V operation. Connect to circuit
board. Press RESET.
3. Connect the valve block to the mixer’s connection pipe (remember the sup-
port sleeves in the connection pipe) and to incoming hot and cold water. If the
mixer has an outlet for connecting a dishwasher, connect the dishwasher’s
connection hose to the mixer’s outlet pipe.
4. Assemble the solenoid valve with the ball valve in the control box. Then attach
the ball valve to the valve plate. Do not forget the filter/packing. If there is a
limited space against the drain trap, the enclosed elbow can be attached in
between to angle the control box 90° out of line.
5. Then fit the connection hose between the outlet on the solenoid valve and the
mixer’s connection for incoming hot water.
6. The mixer valve built into the valve block only supplies the tap with water
during sensor operation. This is set to give hot water on delivery; the exact
temperature and flow can be adjusted using the adjuster screw (see diagram
B).
NOTE:Ifonly coldwaterisrequired(100%)fromthetapduringsensoroperation,
the accompanying cold water plug must be fitted (see diagram C).
7. Turn on the water.
8. Test the activation distance. If the activation radius of the sensor is too
short/long, this can be adjusted using switch no. 6 (rough adjustment) and
the adjuster screw (fine adjustment), see diagram A.
NOTE: Be careful - only small adjustments to the screw are needed to change
the activation distance.
9. Check that the after flush time and the maximum flush time are satisfactory,
otherwise adjust these on the circuit board in the control box. Hot water in Cold water in

Temperature and flow setting
Only cold water for sensor operation
The temperature of the water during sensor operation is determined by a mixing
valve that is built in to the valve block. You can use the temperature screw to
produce fairly cold water, although not 100 % cold water, which sometimes may
be required if you need the water for preparing food etc.
In order to always have 100 % cold water during sensor operation a cold water
plug must be fitted. Remove the cover on the cold water side, and fit the cover and
spring from the hot water side. On the hot water side the ”cold water plug” must
be fitted (included). To do this you only need a 3mm Allen key. When the plug has
been fitted, the tap will always give 100 % cold water during sensor operation.
The function of the mixer valve has been totally blocked, and the water that the
tap now produces during sensor operation can be used as drinking water and for
food preparation.

Removing the sensor eyes
Remove the sensor cable contact in the control box. Pull
out the sensor pack from the foot of the mixer using a small
screwdriver or the tip of a knife. Work the cable and contact
through the hole. Depending on how big the assembly hole
in the bench top is, you may need to remove the mixer and
lift it up a few centimetres to get at the contact.
Reassemble the new sensor pack in the reverse order.

TROUBLESHOOTING AND CORRECTIVE MEASURES FOR THE SENSOR FUNCTION
Sensor function
gives no water
Transformer fault set, AC not
selected and activated on the
circuit board.
The water is shut off
Poor or batteries turned the
wrong way
Sensor distance too short
The solenoid valve is not
working
Dirt in the solenoid valve
Inlet filter clogged
Fault in the electronics
Check that the transformer is set to 12V. And
that the circuit board has AC selected.
Check the water connection
Check the batteries, 4 ea R6 á 1.5 volt, which
must be mounted according to the instructions
in the battery compartment
Try moving your hand closer to the sensor eyes
Activate the sensor eyes and listen for a click-
ing sound
see above
Examine the inlet filter mounted between the
solenoid valve and valve block
Conduct a ”self-test” as described above
Set the Transformer to 12V. Select AC.
Press RESET.
Open any shut offs
Replace batteries, or correct the position
of the battery. NOTE: Use alkaline bat-
teries!
Adjust the sensor gap
If you hear no sound: Replace the
solenoid coil or if necessary the entire
solenoid valve
If you hear a clicking sound - clean the
solenoid valve or replace the membrane
disk, see figure below
Clean the inlet filter
Replace the sensor eyes or circuit board
POSSIBLECAUSE TROUBLESHOOTING CORRECTIVEMEASUREPROBLEMS
The tap will not
turn off
Before additional tests can be made, establish whether the fault is electrical or mechanical by disconnecting the batteries.
If the tap shuts off with disconnected current, the fault is electrical. If the tap continues to run there is a mechanical fault.
Mechanical fault - dirt in the
solenoid valve
Electrical fault - the elec-
tronics prevent the solenoid
valve from shutting off
-
Conduct a ”self-test” as described above
Dismantle the solenoid valve for clea-
ning, see figure below
Replace the sensor eyes or circuit board
Dirt in the solenoid valve, or
leaky membrane disk
Screw apart the solenoid valve and look for dirt
and check the membrane disk
Clean and where necessary replace the
membrane disk, see figure below
The tap is dripping
The sensor distance is too far - Adjust the sensor distance to about 5
cm in front of the sensor eyes
The tap opens/
shuts off con-
stantly The sensor eyes are defective The sensor distance setting is not reacting Replace the sensor eyes
Normal function
When activating the sensor function, a red flashing light is to be visible on the indication lamp (under the sensor eyes) just when the flow
starts.Test:
MoraTemp Duo has a built-in function for self-testing in the electronics unit. This is what you do: Open the control box cover and pull out the
circuit board. Press the ”RESET” button briefly. The result should then be a red flashing light both from the indication lamp on the tap and from
the circuit board, a clicking sound from the solenoid valve and the tap should open. Then a green flashing light on the circuit board, clicking
from the solenoid valve, the tap shuts off, then two red flashes from the indication lamp and on the circuit board. This test confirms that the
electronics are OK.
Clean the
holes when
necessary
Membrane
disk
Maintenance and cleaning
Themaintenancenormallyrequiredinvolves,forthemostpart,keepingthesensor
eyes clean. Use no abrasive cleaning agent or strong substances that might
damage the lenses. If the water contains a lot of particles and dirt, you might
sometimes need to remove and clean the solenoid valve’s water affected parts,
and the dirt filter that is fitted between the valve block and solenoid valve. Be
particularly careful with the small holes in the membrane disk and the surfaces
to which they seal.
Strong sunlight aimed directly at the sensor eyes may also disturb the function.
Theinterval betweenbatteryreplacementvariesalot,but fornormaluse working
life should be year or so.
Always use alkaline batteries for best performance.
When assem-
bling check
that this hole is
correctly aligned
with the cor-
responding hole
on the solenoid
valve.
