WATER CONNECTIONS

Before proceeding, make sure that the humidifier
is disconnected from the main power supply.
Connection to the main water supply
Connect the fill valve and the water supply line using a
soft ¼" poly hose capable of absorbing water hammering
in order to avoid damage to the fill valve. Route the water line
through the bottom of the unit. As soft poly tubing is used in the
installation, install tubing support to prevent tubing collapse and
leaks. The fitting threads onto the fill valve inlet located on the
bottom of the humidifier using a 3/4" G connection (supplied).
NOTE:
A strainer is built into the fill valve fitting
underneath the unit that requires periodic cleaning. Be
sure to allow clearance for access (See Fig. 3.d.).
Water Drain and Drain Hose
The 5500 Steam Humidifier requires a connection to an open
drain. A 10' length of ¾" ID drain hose is included with unit.
Attach the drain hose to the water drain fitting and secure
with the hose clamp provided. The hose must have a constant
downward slope (cannot be kinked, blocked, or create a trap)
and can be routed directly to a floor drain, condensate pump,
or drain standpipe. Trim the drain hose as needed and ensure
that that drain hose is located such that it cannot be blocked
or pinched after installation.
Note: The drain hose should have a smooth bend to an open
drain. A 90 degree elbow or closed piping may cause the
water to back up into the drain pan area of the humidifier,
possibly overflowing under unit.
See Technical Specifications for drain flow rate.
Condensate Pump
When using a condensate pump, ensure pump is capable of
storing about 1.1 gallons in 15 seconds with a pump output of
3 gpm or more.

3.6 STEAM DISTRIBUTION & INSTALLATION
The maximum allowed duct static pressure is 2 in. WC.
IMPORTANT: Allow 5 feet (1-1/2 M) of straight return duct
downstream of the distributor pipe or nozzle for absorption of
the steam. Always allow 3 feet (0.9M) of straight supply duct
upstream of the distributor pipe or nozzle for evaporation of
the steam. Turbulent air flow may require longer lengths.
8" Steam Manifold (included)
The model 5500 Steam Humidifier comes standard with
an 8" steam manifold. An optional steam nozzle and steam
manifolds are available separately for other installations.
The 8" steam manifold should be installed on a vertical surface
and must be angled up (see Fig. 3.e.). The steam distribution
holes must always be facing up; the holes should never be
installed facing downward. A condensate hose is not required.
To install the 8" steam manifold, drill a 1" diameter hole in the
vertical surface of the duct as shown in Fig. 3.g. Apply silicone
sealant to the mounting plate of the tube. Attach the manifold
to the duct using (4) #10 sheet metal screws (supplied).
Connect the steam hose with the hose clamps provided.
