G. Position the plumbing connections on the Solenoid Valve body and snug them in place, but do
not over-tighten the fitting! If any joint leaks when tested and further gentle tightening does not
stop the leak the entire fitting must be replaced. If pipe dope or thread compound is used to
create a leak-free joint use care not to get any sealant in the tubing itself. Any excess may be
flushed through the tubing and cause the Solenoid Valve to stick or clog the Injection Nozzle
[85].
H. Reconnect the wiring as labeled. Make sure all connections are clean and tight.
I. Restore the water supply to the unit. Check the plumbing for leaks on the intake side of the
Solenoid Valve.
J. Restore electrical power to the unit and activate the Humidity Control [81]. Check the Solenoid
Valve for proper operation and the plumbing for leaks on the outlet side of the Valve.
K. Wipe up any spilled water and replace the Side Access Panel. Be careful not to pull or pinch
any wires when replacing the panel.
DOOR LATCH, How To Adjust:
Determine if the Oven Door [41] or Proofer Door [42] is fitting too loose (it will leak moisture and
hot air past the Gasket) or too tight (it will not close properly, or will "pop" open unexpectedly). If it is
too loose the Door Latch [44] must be adjusted OUT (away from the unit); if it is too tight the Door
Latch must be adjusted IN (towards the unit). Please proceed as follows:
A. Loosen the two acorn nuts inside the Latch Cover [45] with a small box wrench. Pull the Latch
Cover straight out from the Door to remove it and then remove the acorn nuts (refer to Figure
#16 on page 39).
B. Open the Door and take careful notice of the adjustment plate position against the body of the
Door Latch.
C. Hold the adjustment plate against the body of the Door Latch with one hand while you loosen
the three mounting screws with the other hand. Back the screws out approximately three full
turns.
D. CAREFULLY move the Door Latch body IN or OUT under the adjustment plate one notch at
a time. Make sure the Door Latch stays straight up and down and tighten the mounting screws.
Test the Door for proper closing and sealing (refer to the DOOR TEST PROCEDURE).
E. Repeat steps "C" and "D" if you are not satisfied with the Door adjustment. If the Door tests as
satisfactory make sure the three mounting screws are tightened securely.
F. Install the acorn nuts on the ends of the top and bottom Door Latch screws. Turn the nuts on all
the way until they just contact the back side of the latch bracket, then loosen them by 1½ to 2
full turns. Install the Latch Cover and tighten the acorn nuts lightly to hold the Latch Cover in
place.
DOOR TEST PROCEDURE:
A. Cut one or two strips of paper approximately 1" wide and 8" to 10" long.
B. Open the Door slightly, insert a strip of paper between the Gasket [46] and Door Jamb and close
the Door.
C. Slowly pull the paper strip out. You should feel some resistance as you pull the strip from
between the Gasket and Door Jamb of a properly adjusted Door. Test the fit at regular 2" to 3"
intervals around the entire Door.
1. If you feel NO resistance at a particular spot the Door is too loose, you have found a weak
or damaged spot in the Door Gasket or the Door Jamb has been bent in.
2. If you feel HEAVY resistance at a particular spot the Door is too tight or the Door Jamb
has been bent out.
