STEP 4
replace water in the collector
loop with HTF mixture.
Mix the propylene glycol HTF and distilled
water mixture in a accordance with Table 4 and
Table 5 in a large clean bucket. You will need
a second empty bucket as well. The charging
process will require a high head pressure pump
capable of producing 50 PSI (115ft. head) pres-
sure to charge the system.
Place the hose for the discharge side of the
pump in the empty bucket. Place the hose for
the suction side of the pump in the bucket with
the HTF. Run the charge pump and allow a
small amount of HTF to transfer to the empty
bucket this step flushes the pump and hoses.
Stop the pump and transfer the hose for the dis-
charge side of the pump to the bucket with the
HTF. Run the charge pump for approximately
30 seconds or long enough to ensure priming of
the pump.
Connect the discharge side of the charging pump
to the upper charge faucet (COMPONENT #9,
FIGURES 15A; 15B; 16A; 16B; 17A; 17B).
