1. COMPACTSTEAM OPERATION
Range of isothermal humidifiers for steam production in rooms. The steam is produced from the water
contained in the cylinder (connected to the mains). The water boils and evaporates due to the electric
current generated by two immersed electrodes in the cylinder.
1.1 Operating stages
• the humidifier opens the fill valve (1) connected to the main water supply;
• the water flows through the hose (2) to the tank (3), the flow restrictor (4) controls the filling speed;
• when the tank is full, the water overflows into the hose (6) and starts filling the cylinder (5);
• once the level of water in the cylinder has been reached, the humidifier closes the fill valve (1);
• the current generated by the immersed electrodes in the cylinder (7) heats the water until it boils;
• the steam exits the cylinder through the outlet (8) and - depending on the model of humidifier - is
distributed directly into the room (using a fan), or into the duct (via a steam line).
Note:
• if the water in the cylinder exceeds the level sensor (9), the humidifier opens the drain pump (11)
and drains the excess quantity;
• if the current generated in the cylinder reaches excess levels, the humidifier opens the drain pump
(11) and drains the quantity of water required to restore the level of current;
• before emptying the humidifier activates the tempering valve (10) to cool the water to 60°C/140°F;
• the humidifier automatically controls the quantity of mineral salts dissolved in the water by activating
the fill (1) and drain (11) pumps;
• the cylinder is fitted with a filter (12) to prevent the mineral debris from blocking the drain pump (11);
• if the humidifier is in standby and does not produce steam for more than 3 days (72 hours), the
water in the cylinder is automatically emptied;
• the fill tank (3) is connected to an overflow hose (13) to prevent contact between the mains water
and the water in the cylinder;
• the current running through the cylinder is controlled by the current transformer connected to the
electrodes (7).

Cylinder life
1.2 Cylinder life
Basic information
The plastic cylinder containing the electrodes is the heart of the humidifier. In the cylinder, during operation, the water is
boiled to produce steam. As the steam does not carry away the minerals dissolved in the water, the concentration of these
increases in proportion to the quantity of steam generated; in addition, some of the salts (above all calcium and magnesium
bicarbonates) tend to foul the electrodes until these are electrically insulated. When a part of the electrodes is covered by lime
scale, the level of the water in the cylinder is raised so that a new section of clean electrodes can conduct the current. At the
end, the electrodes will be completely covered with lime scale and will no longer be able to conduct the current required to
produce steam. The humidifier controller can measure such low levels of current between the electrodes, and signalling that
the life of the cylinder is coming to an end by displaying alarm code E6. Several factors affect the life of the cylinder, which
may range from 500 to 2000 operating hours.
Cylinder life and characteristics of the water
The characteristics of the water, which vary very depending on the site in question, significantly affect the life of the cylinder.
The main characteristics are the quantity of minerals dissolved in the water and their composition. If, for example, the
content of calcium and magnesium bicarbonates is high, significant deposits form and consequently the life of the cylinder is
shortened. If on the other hand the water contains a considerable percentage of chlorides, corrosion may occur, with possible
electric discharges between the electrodes.
Cylinder life and humidity load
Humidity load demands have an effect on cylinder life. Normal installations where humidity capacity is properly sized require
only intermittent periods where full humidifier capacity is required. This allows the water level in the cylinder to be increased
only as electrode segments become insulated by lime scale, which tends to maximise cylinder life.
In certain installations that require constant operation at full capacity, cylinder life is reduced because the water level in the
cylinder is generally much higher, and the electrodes become covered with lime scale more quickly. Installations like this may
result in a cylinder life of less than 1000 hours. Consequently, it is extremely important to correctly size the capacity of the
humidifier in relation to the required humidity load.
Maximum production
Fig.1.c
20%100%
Cylinder life and maximum production
Another factor affecting cylinder life is the maximum production setting. A higher production rate will result in a shorter
cylinder life, and vice-versa. For this reason, models CH*05***** are preset with a maximum production of 70% of the rated
value. Figure 1.c shows the relationship between the maximum steam production and cylinder life.

2. MODELS
Two versions of compactSteam humidifiers are available:
Duct steam distribution Direct room distribution
ENGLISH
Fig.2.a
compactSteam is made in various models that differ in terms of capacity (kg of steam produced per
hour) and voltage (the voltage depends on the national grid). Each model is identified by a 10-character
alphanumeric code. The meaning of each character is shown below:
CH m ss c v xx r
CH means compactSteam Humidifier and is fixed;
m = model: 0 for injection in the duct, F for direct room distribution;
ss = rated steam flow in kg/h (see the table on page 27 for the complete list with the rated steam flow);
c = type of control: V = ON/OFF or 0 to 10 Vdc proportional control;
v = power supply: 1 = 110 VAC single-phase, 2 =230 VAC single-phase;
xx = customisation or xH = complete package (compactSteam + CLIMA);
r = version.
Examples:
CH002V1001: compactSteam for injection in the duct (m = 0), rated steam flow 5.5 pounds/hour /
2.5kg/h (ss = 02), 110 VAC single-phase (v = 1), not customised, (xx = 00), version 1
(r = 1, with drain pump)
Note: Some models may not be available in all countries.

There is no reliable relationship between hardness and conductivity of the water.
Important
do not treat the water with softeners, this may cause the entrainment of foam, affecting the operation of
the unit;
do not add disinfectants or anticorrosive compounds to the water, as these are potential irritants;
the use of well water, industrial water or water from cooling circuits and, in general, any potentially
chemically or bacteriologically contaminated water is not recommended.
IMPORTANT: When installation is completed, flush
the supply hose for around 30 minutes by piping
water directly into the drain, without sending it into the
humidifier. This will eliminate any scale or processing
residues that may block the drain pump and cause
foam when boiling.
3.4 Drain water
• this contains the same substances dissolved in the supply water, however in higher quantities;
• it is cooled to 60°C / 140°F by mixing it with supply water;
• it is not toxic and can be drained into the sewerage system.
3.5 Water connections
Before proceeding make sure that the humidifier is disconnected from the main power supply.
Connection to the main water supply
Install a manual valve upstream of the installation to be able to cut off the water supply, as illustrated in Fig.
3.h. Connect the humidifier to the main water supply using a hose capable absorbing water hammer, to
avoid damaging the fill valve. The hoses are identified by the following CAREL codes: FWH3415000 (1.5 m
/4ft long), FWH3 430000 (3 m /9.5ft long ). Alternatively, a hose with a minimum inside diameter of 6 mm
/ 1/4” can be used. If soft polymer tubing is used, secure this to the wall to prevent it from detaching from
the fill connector and this avoiding water leaks. The threaded fill valve fitting is located at the bottom of the
humidifier (see Fig. 3.g). Remember that the fill valve is fitted with a filter that requires periodical cleaning.
Make sure there is sufficient clearance for maintenance. The water line can be connected either through the
holes at the rear (so that these remain hidden behind the unit) or through the holes at the bottom of the unit.
14
compactSteam +030222070 - rel. 1.4 - 05.09.2017
Water drain
As well as the connection to the main water supply, compactSteam also requires connection to a drain
pipe for emptying the water in the cylinder whenever necessary. The drain tubing can be connected from
the rear (as shown in Fig. 3.i) or from the bottom of the unit using the elbow connector supplied (Fig.
3.g and 3.h).
The characteristics of the drain line are shown in Tab. 3.e.
The drain tubing must have a minimum inside diameter of 32 mm (1-1/4”) and must be secured to the
humidifier drain outlet without requiring additional support. The drain tubing must have a minimum slope
of 5°, and a drain trap must be installed to prevent the return of odors, as illustrated in Fig. 3.h and 3.i.
In addition, a funnel should be used to interrupt continuity in the drain line and prevent flooding inside
the unit.
The compactSteam unit is fitted with a tempering valve that, opening at the same time as the pump, adds
cold water to the drain line, thus ensuring a maximum temperature of the drain water of 60°C /140°F.

To drain the condensate, connect a drain hose (CAREL code 1312353APG) with a drain trap and a
minimum slope of 5° to the bottom of the humidifier (see Fig. 3.L). The condensate hose should run
through the hole located at the top of the fill tank inside the humidifier, as illustrated in Fig 3.k.
IMPORTANT WARNING: for correct operation, the drain trap should be filled with water before starting
the humidifier.
Steam hose
• make the connection between the humidifier and distributor using a hose (it is recommended to use
the steam hoses supplied by CAREL, code 1312360AXX). Unsuitable hoses may weaken and crack
causing steam leaks;
• avoid the formation of pockets or traps where condensate may form;
• avoid choking the hose due to tight bends or twisting.
fasten the end of the hose to the connectors on the humidifier and the steam distributor using metal
clamps (not supplied), so that these do not detach due to the high temperature.
To connect to the cylinder hose steam use the adapter code CHKADAP000.
WARNING: the length of the hose must not exceed 4 m / 13ft.

ROOM steam distribution
compactSteam can distribute the steam directly into the room being humidified. For direct humidification,
both the compactSteam with built-in blower (CAREL code CHF*******) and the duct model (code
CH0*******) can be used, the latter connected to a remote room blower (code VRDCHA1000 for 110 Vac
models, and VRDCHA2000 for 230 Vac models).
The following drawing (Fig 3.m) shows the minimum distance that must be observed when installing the
remote steam blower, so as to avoid burning and the condensation of steam on objects such as lights,
electrical equipment, cold surfaces, etc. For further details on the installation and use of the blower, see
the corresponding manual.
