Loading instructions
After adjusting for dispensing height, you are ready to load
your dishes.
Only load a manageable stack of dishes at a time —
approximately 4” (10.2cm) to 5” (12.7cm). Each DIS model
dispensing tube will accommodate a 26” (66cm) stack of plates
or bowls.
Keep fingers clear from the edge of
the opening
If the stack is over the guide posts and is bottomed out, it is
full. If stack is over guide posts and not bottomed out (the
stack will bounce up and down), adjust the springs. See “Field
adjustment” instructions.
Temperature adjustment – ET & QT models only
ET (even-temp) models have either a 400 or 700 watt
heating element and an adjustable thermostat. The factory
setting for thermostat is “A” which gives an operating
temperature of about 165°F (74°C) and effective plate
temperatures of between 110°F (43°C) to 120°F (49°C)
after about two to three hours of pre-warming.
QT (quick-temp) models have a 700 watt heating element
and an adjustable thermostat. The factory setting for
thermostat is “E” which gives an operating temperature
of about 205°F (96°C) and effective plate temperatures of
between 130°F (54°C) to 150°F (66°C) after about two to
three hours of pre-warming.

Field adjustment
The dispensing height may be adjusted, by following these
instructions in order:
Always wear safety glasses when adjusting
your dispenser. Springs under tension may
recoil when released.
If adjusting a heated model, unplug the unit. Allow
the unit to cool completely before handling.
1) Lock brakes on mobile units before beginning.
2) Unload the dispenser. Remove dispensers from the unit
by grasping the black plastic guide posts and lifting the
dispenser completely out of the unit.
3) There are minimum of six springs per dispenser. When
adjusting, make sure each section has the same number
and size of springs connected to the tube and make sure the
springs are attached in the same order in each section (see
diagram 1). This will prevent the load of dishes from binding.
4) If the dispensing
height is too low, add
springs or replace
current springs with
higher tension springs
(springs with higher
tension may be
ordered from Delfield’s
Parts and Service
Department). Gently
engage one spring at
a time by hooking
the top loop of
the spring into the bracket on the tube frame. Then hook
the bottom loop of the spring into the carrier bracket (see
diagram 2). Add as many springs as necessary.
5) If the dishes are resting too high in the unit, remove springs
or replace current springs with lower tension springs
(springs with lower tension may be ordered from Delfield’s
Parts and Service Department). Gently disengage one

(see diagram 2). Remove as many springs as necessary.
6) If level is appropriate, return tube to cart or counter. If
spring adjustment does not position carrier properly, repeat
procedure trying different springs. If this does not work,
a different set of springs may be required. To order call
Delfield’s Parts and Service Department.
