Vitosol 100-FM/200-FM Installation, Operating and Service
Start-up steps
1. Check and adjust nitrogen cushion pressure in the
diaphragm expansion tank D. Calculate cushion
pressure based on formula (see page 37) and charge
cushion pressure as required.
2. Thoroughly flush system through the system fill
manifold F to remove debris and flux residue (see
page 40).
3. Fill system with solar fluid J through the system fill
manifold F using charge pump or hand fill pump E.
CAUTION
Never mix Tyfocor-HTL with alternative heat transfer
media or with water.
4. Fill system to minimum fluid fill pressure (see page 37).
Typical values:
1-storey home: Static head= 10 ft. (3 m)
System fill pressure= 48.5 psig (3.3 bar)
2-storey home: Static head= 20 ft. (6 m)
System fill pressure= 53 psig (3.7 bar)
5. Purge all air from air vents L and H by running
solar loop pump at maximum speed. After system is
completely vented, shut off air vent valve in top of
system.
6. Set system flow rate (see page 42).
7. Provide overflow container C (minimum size should
equal collector fluid volume).
8. Set control settings: Differentials, maximum tank
temperature.
9. Remove protective film from flat plate collectors or
install the tubes.
CAUTION
Remove protective film from flat plate collector ONLY
after all above steps have been completed.
CAUTION
Never flush with water when it is freezing, if no heat
transfer medium is used.
CAUTION
Never drain the system with a vacuum pump.
