SAPHO KU245 KIMURA wall-mounted thermostatic shower mixer
Application
Thermostatic mixing valves are designed to provide a convenient operation and
save water and heating energy. It offers a high precision of regulating the
requested temperature. The pressure of all mixers sis set to 3 bar at both
inputs in the factory. Under these conditions, the mixer performance is ideal
with any type of water heating.

Technical Data
- A minimum pressure of 0,5 bar without subsequent resistance
- A minimum pressure of 1 bar with subsequent pressure
- Maximum operating pressure of 6 bar (1)
- Recommended pressure of 3 bar (1)
- Maximum water temperature on the hot water inlet 80°C
- Recommended water temperature on the hot water inlet 60 -70°C
- The water temperature on the inlet must be a minimum 2°C higher than the temperature of the mixed water
- Temperature range of the mixed water 15-50°C
- Maximum flow rate at a pressure of 3 Bar – 6-12 l / min (2)
- Safety stop button 38°C (3)
- Operating temperature 0°C – 50°C (4)
At a pressure higher than 5 bar, we recommend installing a pressure-reducing
valve to the inlet conduit (1) The flow rate is adjustable and will vary
depending on the inlet temperature and pressure.(2) The SafeStop button 38°C
is set at a hot inlet temperature of 65°C and a cold inlet temperature of 12°C
at a pressure of 3bar. (3)
The freezing of water in the mixer causes its damage! (4)
New Installation
Warning!
Before connecting the mixer, the inlet conduit must be flushed properly and
get free of impurities (especially for new water distributions). The hot water
inlet must be on the left side and the cold water inlet on the right side of
the front view of the installed mixer. If not, the mixer will not work! Use a
spirit level and an eccentric connection to install the mixer body in a
horizontal position parallel to the wall. Check the seam tightness for leaks
after the installation. During the period of use the thermostatic head almost
never turns (38°C is usually a convenient temperature). For smooth work it is
recommended to turn it a few times (from cold to hot water) at least once a
month.
Installation
Continue with the installation according to the following diagrams.
The installation must be performed by a qualified person.
Temperature Setting
The SafeStop button 38°C is set at a hot water inlet temperature of 65°C and a
cold water inlet temperature of 12°C at a pressure of 3 bar. Since the
temperature of the SafeStop can vary depending on the inlet temperature and
pressure changes, it´s possible to change its position during the use. If the
SafetyStop is not set at 38°C, follow these instructions:
Turn on the water and measure it´s temperature using a thermometer. Press the
safety han-dle and rotate the temperature controller in the position with 38°C
temperature. Without further rotation of the handle, remove the cover and the
screws and pull out the loosened handle. Re-attach the handle to the mixer, so
that the mark shows 38°C.
Temperature Limitation
The safety stop button reduces the temperature range to a maximum 38°C, after
pressing the button on the mixer handle the limit can be canceled and you can
gain a higher temperature.
Operation
The requested temperature can be set with the thermostat handle on the left
side of the mixer, as shown in the picture below. If you need a temperature
higher than 38°C, push the safety stop and continue turning the handle. Beware
of possible burning with hot water!Using the handle in the right side you can
control the water flow while maintaining a con-stant temperature at the
outlet. For maximum flow the valve can be fully opened. 
Thermostatic Cartridge
To ensure the long-term functionality of this product, we recommend a regular
(1x per year) maintenance of the thermostatic cartridge. Close the main water
supply. Loosen the fixing screws in the bottom of the mixer -as shown in the
picture – to unloose the cartridge. You can leave the handle on the cartridge.
Pull out the cartridge (it´s not screwed into the mixer body) and remove dirt
from it, using a vinegar or limescale cleaners. Then slide cartridge back into
the mixer body and fix it with a screw.
Cleaning and Maintenance
To clean the mixer surface, use available cleaners against limescale or just a soap water. Avoid agents containing acid, abrasive agents and steel wools. Plastic and rubber parts can be cleaned the same way.
- The perlator strainers and shower head holes must be cleaned regularly to prevent clogging.
- In areas with hard water, more frequent cleaning is required.
Problems and Solutions
Water temperature control does not work
If the water of a required temperature is not coming out, turn the handle
several times to control the temperature from hot to cold. Check if the mixers
work properly in the same place at the same time. Check if the filters on the
inlet are not clogged. Remove the thermostatic cartridge and clean it as
described in paragraph no.7. If the defect cannot be removed, replace the
cartridge with a new one.
If there´s no water at a temperature of 38°C coming out in the safety stop
position Follow the instructions in paragraph no.5 – Temperature settings
If turning the thermostatic cartridge is stiff or difficult The problem often
arises after longer disuse of the mixer. Turn on the water and turn the
temperature handle until it runs smoother. Remove the thermostatic cartridge
and clean it as described in paragraph 7.1.
Warranty
-
The supplier of the water mixers grants a 6-year warranty for the seam tightness and
a 24month warranty for the surface finishing and functionality of the thermostatic cartridge, hand showers, shower hoses and other parts since the date of sale confirmed on the warranty certificate, if: • a warranty certificate and a proof of sale is documented -
Installation and the way of use were in accordance with the instructions, which are an integral part of each product.
