1.1.7 Operating principle
The blower is connected to the power supply. When steam enters the blower, after a certain time either
the thermostat detects a temperature of 50°C or the output (terminal J19) on the c.pHC controller gives
the signal and the fans are activated. The air, taken in from the rear, is mixed with steam before being
delivered into the room, where it is easily absorbed. The blower features two different types of
operating logic:
1. independent of the humidifier;
2. managed directly by the humidifier (c.pHC). The controller delays blower activation for a set time.
Deactivation can also be delayed to allow the blower to dry.
Note: the 230 Vac power supply to the steam blower is supplied externally by a dedicated line. If the
humidifier has to manage the steam blower (with c.pHC controller), use the J19 contact as in the
following drawing.

Note: use the previous drawing to supply in parallel up to 3 steam blowers. With 4 steam blowers,
use an external relay (not supplied), managed by a 24 Vac command from the c.pHC controller. The
230 Vac power supply to the 4 steam blowers remains external.
Removing the jumper
Notes:
lif the humidifier is not fitted with the c.pHC controller, remove the jumper. The blower will be
activated by the built-in thermostat;
lfor the list of humidifiers where the jumper must be removed, see the following table.
Unscrew the screws to remove the jumper P.

2. Preparing for assembly
The blower must be mounted or on the wall and connected to the humidifier via the steam hose.
The maximum length of the steam hose is 4 m.
Note: observe the minimum distances shown in the following figures to prevent the flow of
humidified air from coming into contact with people, electrical equipment, false-ceilings and cold
surfaces before the steam is totally absorbed by the atmosphere.

Notes:
ldimension C+E can be lower if it is not possible to transit in front of the blower unit;
lsee the humidifier manual for details on positioning.
2.1
Requirements
2.1.1 Steam hose
Follow these instructions when installing the steam hose:
lonly use hoses supplied by CAREL; hoses made from other materials may adversely affect operation of
the system;
lthe steam hose must be secured by supports (clamps, brackets) so that it does not bend and does not
weigh on the humidifier. A hot hose is more likely to bend;
lthe minimum radius of curvature of the steam hose is 5 times the inside diameter;
lthe steam hose must have a minimum slope in order to drain condensate back to the humidifier; in
any case, always install a condensate drain at the lowest point on the steam hose;
lminimise the length of the steam hose so as to reduce heat loss. Avoid the formation of pockets or
traps where condensate may accumulate;
lchoking (due to bends or twisting of the hose) can cause excessive back-pressure in the humidifier
cylinder when the unit is operating and consequently sudden steam outlet.
Important:
ldo not install a stop valve in the steam hose;
lwhen installation is complete, flush the steam line to remove any contaminants and processing

residues.
lexposure of the skin to a jet of hot steam may cause severe burns;
ldo not over-tighten the hose clamps (max. torque=180 N·cm).
2.1.2 Condensate hose
Follow these instructions when installing the condensate hose:
lthe condensate hose may be filled with hot water or steam: contact with the skin can cause serious
burns;
lconnect the hose to a drain in accordance with national and local regulations in force;
lthe condensate hose must have a minimum downward slope and must flow into a 200 mm high drain
trap: the drain trap must be at least 300 mm below the connection to the blower.
lcondensate drains must be installed at all the lowest points and wherever the drain line goes from
horizontal to vertical. The drain line must be connected to a “T” connector and have a minimum
downward slope. The drain trap must be at least 300 mm below the connection.
lmake sure that the condensate drain lines are not blocked;
ldo not over-tighten the clamps on the condensate hose.
Important: before starting the humidifier, fill the drain traps with water.
