Manual
Fig.5.3.2 – Manually start pump by pushing all three buttons to enter program (PRGM) mode then push
down button. To shut off, enter PRGM mode and push up button.
TIP: Alternate over pressurizing fluid to purge expansion tank and manual starting
pump to purge pump and manifold. Repeat four or five times, allowing for purged
air to move through and exit system to ensure all air has been purged.
8. Appliance should now be charged to a fluid pressure of 30 psi.
a) With charge pump operating and fluid circulating, close ball valve on line returning fluid to
reservoir (at return assembly). A rapid increase in pressure will again be observed on
pressure gauge, until appliance pressure reaches 25 psi – the expansion tank air
pressure. Pressure then increases more slowly.
b) When appliance pressure reaches 30 psi, switch off charging-pump and quickly close ball
valve at appliance fluid inlet.
c) If pressure is below 30 psi, open inlet ball valve and switch on charge pump momentarily.
Switch off pump and close valve as before. If pressure is above 30 psi, let very small
volume of fluid out of appliance outlet.
9. Disconnect supply and return charging hoses from appliance. Open ball valves, and allow
fluid in charging lines to drain back into reservoir.
If small bits of copper from de burring enter line-set, they may get lodged in
charging port (Parker hydraulic quick connect nipple of lower manifold). This may
cause quick connect to leak. If quick connect leaks, drain system of fluid and
remove quick connect. Back flush quick connect, reinstall, and recharge Appliance.
Pour remainder of fluid back into glycol jug and label “50/50 propylene glycol –
water”. This fluid may be re-used in charging other appliances. Fluid will react with
air over time. Transferring fluid to a smaller container will limit contact with
air. Do not use if fluid becomes cloudy or discolored.
Check and follow all local environmental regulations regarding storage and
disposal of food-grade propylene glycol heat transfer fluid.
6 – Collector Flashing and Leaf guard Installation
Collector flashing and leaf guard are designed for pitched roof installations only.
Flashing and leaf guard should not be installed on rack-mounted collectors due to
increased wind loads.
