broken glass that could fall on passersby, if the tubes were ever damaged. (E.g. during an extreme storm

due to flying debris or tree branch falling on the collector). It may be necessary for a barrier of to be

installed below the collector to catch any falling materials, such as a clear roofing material.

󱚡 WARNING

If the solar collector is installed above an area where people may walk, take appropriate

measures to minimize the risk of injury, if a tube ever broke and glass fell onto the ground or

people below.

5.6. Connection to Plumbing

5.6.1. Plumbing Connection

a) Once the frame has been mounted and the manifold attached, the manifold header may be connected to

the system plumbing.

b) Delayed Commissioning: If the collector is to be installed (including

evacuated tubes) prior to plumbing connection (e.g. on new house), high

temperature resistant covers (aluminum foil) should be placed over the

header inlet and outlet to prevent any contaminants (bugs, spiders, leaves,

dust) entering the header. The solar collector will not be damaged by a short

period of dry stagnation (1-2 weeks), however leaving the solar collector

exposed to the sun and not commission for extended periods will void the

warranty.

c) Soldering: The header connection is standard 3/4” (7/8” OD) copper pipe

size and must be connected by soldering using 90/5/5 (tin/silver/antimony) or

equivalent lead free solder. Maximum allowable lead content in solder for

contact with potable water is normally 0.2% (or as specified by local

plumbing code). In addition only use solder that is able to withstand

temperature of at least 482

F (250

C) without softening.

When soldering, care must be taken to avoid exposing the manifold casing to the torch flame. Place a wet

cotton cloth around the base of the header pipe to reduce at the silicone rubber seal. Point the flame away

from the collector and anything flammable while soldering. Take care not to set the wet rag on fire. It is

advisable to purchase a pocket fire extinguisher and keep it handy while soldering.

✖ Damage to collectors and other components incurred by extended dry or wet stagnation will not be eligible for

warranty claims.

5.6.2. System High-Point Air Purge

a) In order to completely purge the air from direct flow and closed loop systems, a Tee fitting must be

installed at the high point in the system. Usually, this Tee can be soldered direction on the collector outlet

(hot), instead of just a 90 elbow. The Tee side-connect (bull, arm) will then be on the collector header pipe,

the lower Tee connect (pass-thru, run) on the Return Line and a ball valve

can be then be installed on the uppermost Tee connect (pass-thru, run). On

the top side of the ball valve, an automatic air vent should be installed

TEMPORARILY. After flushing and charging is complete, the ball valve

should be closed and the air vent removed and stored on-site. Leaving the

air vent in place will lead to degradation over time potentially forming a leak

on the roof.

b) Complete instructions for purging the collector of air are presented in

detail in sections 7 & 8.

5.6.3 Leak Testing

a) BEFORE filling the solar loop piping, the collector must be plumbed to

the Supply (Feed) and Return Lines and an AIR PRESSURE TEST
