Commissioning
Procedure
With the shower electrical supply isolated, check that the maximum temperature switch (see page 26)
matches the intended use; (41° BEAB Care)
With power applied to the shower:
Check terminal voltage at the shower is within the range 230V +/- 10%
Turn on the shower and enter ‘Cold Water Flushing’ mode (see page 27)
Check inlet water supply temperature is within the range; 3 to 28°C (5 to 20°C BEAB Care)
Exit Cold Water Flushing when completed
Turn on the shower and by pressing the Temp + button, set the outlet water temperature to
maximum, and by pressing the Flow + button set the flow rate to maximum. Then carry out the
following sequence:
Record the outlet water temperature and flow rate;
Reduce the water supply flow rate at the
inlet
of the shower to 2.5 lpm;
Record the outlet water temperature at the reduced flow rate;
The outlet water temperature should not exceed the maximum temperature switch setting (see page 26).
Record details of test equipment (thermometer, voltmeter, flow meter etc.) used for the measurements.
In-Service Tests
The purpose of in-service tests is regularly to monitor and record the performance of the shower.
Deterioration in performance can indicate the need for service work on the shower and/or the water
supplies.
Procedure
Using measuring equipment to the same specification as used in commissioning the shower, check that:
The water supply temperature is within the range; 3 to 28°C (5 to 20°C BEAB Care)
The terminal voltage at the appliance is within the range 230V +/- 10%
If the maximum outlet water temperature has changed by more than 1°C from the previous test
results, record the change and check
... for any damage/blockage to the shower, inlet filter, hose and handset:
... any in-line or integral check valves or other backflow prevention devices are in good working order;
... any isolating valves are fully open.
With an acceptable outlet water temperature, complete the following procedure:
Record the outlet water temperature and the flow rate at maximum settings;
Reduce the water supply flow rate at the
inlet
of the shower to 2.5 lpm;
Record the outlet water temperature
Record details of test equipment (thermometer, voltmeter etc.) used for the measurements.
If an acceptable outlet water temperature cannot be achieved i.e. temperature is greater than the
maximum temperature switch setting (see page 26) by +1° or more then service work is required.
