MAINTENANCE - BEAB CARE
These tests should only be performed by a qualified engineer.
Commissioning and In-Service Tests
D.1
Commissioning
D.1.1
Purpose
Since the installed supply conditions are likely to be different from those applied in
production it is appropriate, at commissioning, to carry out some simple checks and tests on
each instantaneous water heater to provide a performance reference point for future
in-service tests.
D.1.2
Procedure
D.1.3
With the appliance turned off, check that:
a)
the water supply temperature is within the range 5 to 20°C;
b)
the terminal voltage at the appliance is within the range 230 ± 10%.
D.1.4
Turn on the appliance and if the maximum outlet water temperature is adjustable, adjust
this in accordance with the manufacturer's instructions to the maximum permitted BEAB
care temperature. Then carry out the following sequence:
a)
record the supply voltage at the terminals of the appliance;
b)
record the outlet water temperature and the flow rate resulting from the setting;
c)
reduce the water supply flow rate at the inlet of the appliance by at least 50% or to the
lowest value at which the appliance continues to deliver an output of heated
water, whichever is the greater pressure;
d)
record the outlet water temperature and the reduced flow rate;
The outlet water temperature should not exceed 43°C for a shower.
e)
record details of the equipment, thermometers etc, used for the measurements.
