Referring to Figures 14-17, it is important to note that:
1. The cooling coil sections and the evaporative (or honeycomb) humidifier sections without recirculating pump

are equipped with a condensate drain pipe. (Item 1, Figure 14 (A, B)).

2. For evaporative humidifier sections equipped with are circulation pump, the drain pipe (used typically for
FWD 08 2
cleaning purposes, item 3, Figure 16 (A, B) needs to be connected to a shut off valve without siphon. There is

also an additional overflow pipe which needs to be connected to a siphon. (Item 1,Figure 15 (A, B)).

Figure 16 indicates the fresh water inlet for wasted water type or steam type humidifier sections. The freshwater

flow control in the section is ensured with a solenoid valve. It is recommended to fit a shut off valve to facilitate
FWD 20 2
the maintenance and a pressure regulator on the water entry for proper operation. The fresh water inlet must be

connected to the supply line with a flanges set.
Figure 15 indicates the fresh water inlet for evaporative humidifier sections equipped with a recirculating pump.
The fresh water flow is controlled with a floating valve located into the internal water tank. It is recommended to fit a
shutoff valve on the fresh water inlet to facilitate maintenance. The freshwater inlet must be connected to the supply
line with a flanges set.
The height of the U-trap varies upon the pressure inside the section and is given in mm of water column.
