10. Apply a little food safe grease to the fittings on the solenoid valve and on the back side of the half
ball end of the tubes.
11. Mount solenoid valve on bottom tubing first (the fitting with the restrictor and screen is the lower
one; the arrow on the valve should point upwards), do not tighten yet with spanner.
12. Mount upper tubing.
13. Tighten all nuts, retain fittings while tightening.
Steam valve (solenoid steam valve is optional)
1. Remove electrical plug from coil.
2. Loosen 21 (sometimes 20) mm nut from steam valve (see Figure M 21b).
3. Loosen 20 mm nut on tube to top of boiler, retain the fitting with a 17 mm spanner.
4. Take out valve with fitting and short copper tubing.
5. Remove fitting and short copper tubing from valve and clean.
6. Mount fitting and copper tubing on new valve with a drop of Loctite, check the flow direction of the
new valve (little arrow), use a new copper O-ring on the fitting.
7. When not already mounted: mount new coil with metal ring on coil at side of valve, do not over
tighten the 14 mm nut.
8. Remount valve with fitting and tubing, let coil point down, use a little food safe grease to the
fittings on the valve and on the back side of the half ball end of the tubes.
9. Mount electrical plug on coil with rubber seal and screw.
Check your work, solve problems
1. Connect pump motor to electrics, o
pen water mains, switch machine “on”, check for leakage and
proper functioning. Use a blind filter to pressurise the tubings on the group valves.
2. Tighten nuts and/or fittings when necessary. When tightening a fitting to a valve, loosen the tubing
first, tighten fitting and then re-tighten the tubing. Do not over tighten fittings on a valve.
3. If a fitting keeps leaking, remove tubing from fitting and take the fitting out of the valve. Use a new
copper O-ring when remounting. If this does not have the desired result, use a drop of Loctite or a
few windings of Teflon tape between fitting and valve for better sealing.
4. If a tubing keeps leaking, unscrew the nut from the fitting (retain fitting with a spanner) and check
the half-ball on the end of the tubing. You may have tightened the nut with the half-ball askew to
the fitting. Apply a little food safe grease to the back end of the half-ball, position the tubing
correctly to the fitting and tighten nut. If the damage to the half-ball is not too severe, the tubing
will seal, if it does not seal: replace tubing.
5. Remount body panels and cup warmer.
