electromechanical kJ Btu counter plus digital-panel meter
indicating sensor temperatures, differential temperature, flow
rate, and watt Btu per minute or hour.
b.
[Water] [and] [Heat Transfer Fluid] Leak Detection: UL-listed
system consisting of a sensor probe, control panel, and LED
indicators for [water; yellow,] [and] [heat transfer fluid; red,]
with audible alarm at minimum 75 dB sound level; reference 10
exponential minus 12 watts.

INSTALLATION
3.1.1
Solar Collector System
**************************************************************************
NOTE: Disinfect domestic water systems, if
connected with solar collector panels. Provide
disinfection provisions in either Section 15400,
"Plumbing Systems," or another appropriate project
section.
**************************************************************************
Install the solar collector system in accordance with this section and the
printed instructions of the manufacturer. [Disinfect domestic water
systems, if connected with collector panels, in accordance with Section
15400N, "Plumbing Systems."] Prior to system start-up, protect collector
from direct sunlight.
3.1.2
Piping Installation
Accurately cut pipe to measurements established on site and work into place
without springing or forcing. Locate piping out of the way of windows,
doors, openings, light fixtures, electrical conduit, equipment, and other
piping. Provide for expansion and contraction. Do not bury, conceal, or
insulate until piping has been inspected, and tested. Locate joints where
they may be readily inspected. Provide flexibility in piping connected to
equipment for thermal stresses and vibration. Support and anchor piping
connected to equipment to prevent strain from thermal movement and weight
from being imposed on equipment. [Provide seismic restraints in accordance
with SMACNA Seismic Restraint Mnl.] Install hangers and supports in
accordance with MSS SP-69 and MSS SP-89, unless otherwise indicated.
3.1.2.1
Fittings
Provide long-radius ells wherever possible to reduce pressure drops. Do
not bend pipes, miter pipe to form elbows, use bushings, or notch straight
runs to form full-sized tees. Provide union for disconnection of valves
and equipment for which a means of disconnection is not otherwise provided.
Provide reducing fittings for changes of pipe size.
