so that the flow direction arrow faces
the storage tank.

Step 24
• The pipe from the PTR valve
must
:
– be easily seen
– pose no risk of damage to the
building or injury to persons
– be plumbed to waste to comply
with AS/NZS 3500.4 and local
plumbing codes
• The panel drain line
must
be
plumbed safely to the waste drain
and
must
comply with AS/NZS
3500.4 and local plumbing codes.
• This system may periodically drain
water from the collectors to protect
the system from extreme hot or cold
