Note
If your local plumbing code requires to install the limiter to
reduce the total flow of water in the shower to 2gpm at 80psi,
see Fig. [2].
Safety notes
Protection against scalding
It is recommended that near points of discharge with
particular sensitivity to the outlet temperature
(hospitals, schools, nursing and retirement homes)
thermostatic devices should be installed which can limit the
water temperature to 109°F (43 °C). This product is limited at
109°F (43°C). It is generally recommended that the temperature
of shower-systems should not exceed 100°F (38 °C) in
nurseries and specific areas of care centres. Use Grohtherm
Special thermostats with special handle to facilitate thermal
disinfection and appropriate safety end stop. Applicable
standards and technical regulations for drinking water must be
observed.
Application
Thermostat mixers are designed for hot water supply via
pressurised storage heaters and, utilised in this way, provide the
best temperature accuracy. With sufficient power output
(from 18 kW or 250 kcal/min), electric or gas instantaneous
heaters are also suitable.
Thermostats
cannot be used in conjunction with
non-pressurised storage heaters (displacement water heaters).
All thermostats are adjusted in the factory at a flow pressure
of 43.5 psi on both sides.
Should temperature deviations occur on account of special
installation conditions, the thermostat must be adapted to local
conditions (see Adjusting).
Specifications
Safety stop 100 °F
Hot water temperature at supply connection min. 4 °F higher
than mixed water temperature
Thermal desinfection possible
Minimum flow rate
= 1.3 gpm
If static pressure exceeds 72.5 psi, a pressure reducing valve
must be fitted.
Installation
Reversed connection (hot on right - cold on left).
Replace thermostatic compact cartridge, see
Replacement parts, page 30, Prod. no.: 47 175 (1/2”).
Installation of the shower rail
When installing e.g. on plasterboard walls (not solid walls) it
must be assured that an appropriate reinforcement is in place to
ensure sufficient strength.
Adjusting
Temperature adjustment, see page 27 Fig. [1].
Operation
The safety stop limits the temperature range to 100°F
(38 °C). The 100°F (38 °C) limit can be overridden by
pressing the button, see page 27 Fig. [1].
Shut-off valves, see Fig. [2].
Prevention of frost damage
When the domestic water system is drained, thermostat mixers
must be drained separately, since non-return valves are installed
in the hot and cold water connections. For this purpose, the
mixer must be removed from the wall.
Maintenance
Inspect and clean all parts, replace if necessary and
lubricate with special valve grease.
Shut off the hot and cold water supply.
Thermostatic compact cartridge,
see page 28 and 29.
Readjustment is necessary after every maintenance
operation on the thermostatic compact cartridge
(see Adjusting).
Shut-off valves, see page 28 and 29.
Readjustment is necessary after every maintenance
operation on the shut-off valves, see page 29.
Showers, see page 30.
The function of the SpeedClean nozzles is guaranteed
for a period of five years.
Thanks to the SpeedClean nozzles, which must be regularly
cleaned, limescale deposits on the rose can be removed by
simply rubbing with the fingers.
Replacement parts
