4. Adjust the flowmeter to the recommended 3 gpm (11.4 lpm).
5. Complete the drain connection on oven side by connecting
WATER OUTLET to the closed loop
system (Figure 6).

WATER DRAIN must be left open-to-atmosphere. Make closed-
loop connections using WATER OUTLET (Figure 6).
Warning!
Never allow WATER DRAIN to be plugged. A hot oven generates
a small amount of steam when the water is first turned on.
Steam can burn skin.
Caution!
Design the drain system to prevent operator injury from high
temperature or pressure buildup. Piping must withstand short
periods of up to 500 °F (260°C) temperatures (662 °F (350°C) for
LCD ovens). Insulate drain lines or install warning labels stating
the potential high temperature or pressure hazard.
4.2.2.2. Air Atmosphere with Optional Water Cooling Model
1. Connect Clean Dry Air (CDA) line to DRY AIR 100 PSI at the connections panel (Figure 6).
2. Install water connection for cooling coils to WATER INLET (Figure 6). Verify the valve on the
flowmeter is turned OFF, that is, fully clockwise.

Clean Dry Air pressure supplied should be at 100 psi (6.9 bar).

Water pressure supplied to the oven must not exceed 100 psi
(6.9 bar). Despatch recommends installing a regulator to prevent
surging.
3. Check for leaks by slowly opening the valve on the flowmeter and allowing any air to bleed
out.
