Close the downstream isolating valve (field supply).

Install an Allen key on the calibration screw in the centre of the plastic cover.
Rotate  it  clockwise  to  increase  the  outlet  pressure  and  anticlockwise  to
reduce it.

Check for correct operation of the temperature and pressure relief valve. Manually
operate  the  temperature  and  pressure  relief  valve  to  ensure  free  water  flow
through discharge pipe. Turn knob left.

11.5 To drain the domestic hot water tank

DANGER: RISK OF BURNING

The water in the tank can be very hot.

Prerequisite: 

Stop the unit operation via the user interface.

Prerequisite: 

Turn OFF the respective circuit breaker.

Prerequisite: 

Close the cold water supply.

Prerequisite: 

Open  all  the  hot  water  tapping  points  to  allow  air  to  enter  the

system.
