DO NOT OPEN ISOLATION VALVES DURING PROCESS OF FLUSHING THE
PIPING LINES.
2.6.3 Piping Leak Check
Close return side flush valve and perform leak check for a minimum of 30
minutes at city water pressure. Examine all piping connections for leaks. If
a leak is found, isolate and eliminate the leak. Repeat piping flush (see
Section 2.6.2) if required after repair is performed.
2.6.4 Piping Line Purge
Once a successful leak check has been performed, all water must be
drained from the piping lines. Open all drains (including drains installed
at the base of every rise) and drain all piping runs. Compressed dry air or
dry nitrogen may be used to assist in purging piping of excess water and
to dry piping prior to charging system with glycol solution.
2.6.5 Fill System
Fill 50 gallon tank and entire water piping loop independently as outlined
below with a mixture of propylene glycol/potable, distilled water (35% by
volume). If city water is used in place of potable, distilled water, run city
water through a De-Ionization filter. See Table 1 below for approved
glycol vendors. The optimum level of propylene glycol in the system is 35%
by volume.
DO NOT OPERATE OUTSIDE THE ALLOWABLE GLYCOL PERCENTAGE
RANGE. Percent glycol solution below the allowable range may lead to
the rupture of piping lines and damage to the pump. Percent glycol solution
above the allowable range may inhibit proper pumping ability which could
lead to damage to the pump. DO NOT USE AUTOMOTIVE ANTIFREEZE.
USE OF AUTOMOTIVE ANTIFREEZE MAY DAMAGE SYSTEM.
