Set-up
1.
Select the location for installing
your oven.
Single Oven Placement
Place the oven on a bench top or other framework capable of holding at least
250 pounds. The oven must have a minimum of three (3) inches in the rear to
provide proper ventilation. If possible, provide room at the sides and rear of the
oven for maintenance. The oven exhaust opening is at the rear of the left side of
the oven; allow at least two (2) inches clearance here as well. The oven may be
placed next to another cabinet on its right, or next to another oven, with three-
quarters of an inch clearance (measure with door open).
Make sure the oven is level and plumb; this will assure proper heat distribution
and operation of all mechanical components.
Multiple Oven Placement
Up to three ovens may be stacked vertically, either with or without the optional
framework / base supplied by Despatch. NOTE: in the LCC1-51 model, only two
ovens may be stacked vertically. Make certain that the supporting surface is
capable of holding the weight of three ovens (750 pounds, not including support
framework) or weight of two ovens in the LCC1-51 models.
The holes in the rear oven feet may be used to bolt the ovens together by
removing the hole plugs in the top of the mating oven beneath.
2.
(Nitrogen models only) Connect the nitrogen supply line to the inlet marked
nitrogen on the side of the oven. The nitrogen supply should run at 70 PSI but
not more than 80 PSI. Check for leaks.
3.
(Nitrogen and Water Cooled Models) Install water connection for cooling coils to
the inlet marked "Water Inlet." Verify the valve on the flow meter is turned off
(fully clockwise). The water supply to the oven must not exceed 100 PSI. It is
recommended to install a regulator to prevent any surge. Check for leaks. Slowly
open the valve on the flowmeter and allow any air to bleed out. Failure to do this
will result in damage to the flowmeter. Repeat this procedure if water supply is
shut off. Adjust the flowmeter to 3 gpm (recommended amount of flow.
4. (Nitrogen Models only) Make the drain connection at the side of the oven. Note
there are two drain connections: water outlet and water drain (see photo on next
page). NOTE: The water outlet may be connected in a closed loop system, but
the water drain must be left in an open-to-atmosphere condition.
WARNING:
Do not use the oven in wet, corrosive or
explosive atmospheres unless this oven is
specifically designed for a special
atmosphere.
CAUTION: Design the drain system to prevent operator injury from high temperature
or pressure buildup. Piping must be able to withstand short periods of up to 500 °F
(260 °C) temperatures [662 °F (350 °C) for LCD ove ns]. Drain lines should be
insulated or warning labels installed stating that a hazard exists.
