Product Description
DESCRIPTION
All sensitive electronic equipment
requires a stable environment for
optimum performance. The
Ecosaire®Precision Environmental
Control system provides the best
possible protection for any
application.
®
The Ecosaire
product line is
made up of feature-rich, energy efficient premium products that are
available in sizes and configurations
to suit any application - even corrosive industrial process environments.
Ecosaire®contains unique, highly
engineered subsystems that no other
manufacturer duplicates, ensuring
continuous, simultaneous control of
temperature, humidity, air purity and
air flow at each operating site.
Ecosaire®performs with the high-
est energy efficiency through intelligent design: less energy wasted on
undesired latent cooling, on-demand
dehumidification, and the state-ofthe-art Supervisaire®Control
System. These new controls offer
maximum design flexibility, networkable units, BACNETTM, and
TM
MODBUS
compatibility. This
allows remote monitoring and alarm
logging from either a graphics display
panel, personal computer, or via
modem.
The Ecosaire
®
product line offers
the maximum in environmental control performance and the lowest lifecycle cost of ownership.
Stable environmental conditions
are further ensured by on-demand
dehumidification. Unlike conventional computer-grade systems that con-
®
stantly dehumidify, Ecosaire
eliminates the costly process of removing
and then replacing moisture.
The Supervisaire®Microprocessor
Controls provide extremely userfriendly, programmable monitoring
and control for all Ecosaire
®
Precision Environmental Control systems. Individual Ecosaire®units can
be connected on a built-in local area
network together with a supervisory
panel complete with a backlit graphics display for robust, redundant
environment control. At the same
time, the network can be connected
to a personal computer supervisory
system, or to a BACNETTM, or MOD-
TM
BUS
network.
The LCD panel is large and easy
to read (4 x 20 characters) and the
simple layout provides an easy-touse interface for the operator.
English language menus (other languages available) and built-in diagnostics walk the user step-by-step
through the monitoring and control of
the system.
A powerful 16-bit microprocessor
ensures high program-execution
speed and efficient real-time management of even the fastest transients.
The computer-site conditions and
utilities will determine the type of
environmental control units selected.
A cooling-load calculation based on
design criteria should be performed
according to standard air-conditioning practice. The calculation should
include the heat gains of: exterior
walls and windows; area exposed to
unconditioned spaces (i.e. partitions,
ceilings, and floors); people; lighting;
and all computer and auxiliary
equipment. With this information
the type, size and number of
®
Ecosaire
units can be selected to
best match the equipment configuration in the computer room.
Allowances for expansion and redundancy should be considered at this
time.
While many important factors
require evaluation when designing a
computer room, the most important
are security, expandability, location
within the building, proximity of related data processing operations and
proximity to outdoor air-conditioning
components. Computer rooms are
best located in a central part of a
building so as not to be affected by
outside temperature and humidity.
When a room must be designed with
an outside wall, the wall should be
insulated and windows should be
kept to a minimum. Thermopane
windows should be used to prevent
condensation. Equipment access
through doors, elevators, etc., as well
as elevator capacity, must be
carefully considered.

Air-Cooled Direct Expansion
The Ecosaire®unit operates its refrigeration system as needed to
control room conditions.
Heat is transported via refrigerant-vapor flow to an outdoor air-cooled
condenser. The refrigerant liquifies in the condenser and returns to the
Ecosaire®unit.
Outdoor condensers are rated for 95°F (35°C) ambient with optional
models available for higher or lower ambient temperatures. They are
constructed of copper tubes and aluminum fins. A factory-wired control
panel is provided for field connection. Fan cycling and pressureactuated fan speed control maintain head pressure of either compressor
down to -20°F (-29°C). Optional flood-back controls are available for
either 30°F (-34°C) or -40°F (-40°C) operation.

Moisture Migration Building Construction
In order to prevent moisture migration, the room (including the ceiling
plenum, if any) must have a sealed
vapor retarder. Rooms with concrete
walls or floor should be painted with a
rubber- or plastic-based paint. Doors
should seal tightly and must not have
grilles in them.
Light fixtures must be selected to prevent overheating, and should not allow
room air to escape into the ceiling
plenum.
Because of the small number of personnel in a typical computer site, outdoor air should be reduced to less than
5% of the total circulated air. If outdoor
air is introduced, it must be filtered. The
effect of bringing in outdoor air must be
added to the cooling and dehumidification loads.

Unit-Duct Connection Ductwork Installation
Important!
Poor duct design can
reduce the amount of air
delivered.
Duct design must conform to the
ASHRAE low-pressure, low-velocity
duct standards. If there is a question concerning duct design, sizing,
choice of materials, air velocities,
or static pressures contact
Ecosaire for assistance.
Air velocities should be kept low
to allow good air movement and
low noise. Higher static pressures
result in higher power requirements
and increased noise. The maximum external static pressure is
specified for each unit. Static
pressures higher than specified
may reduce air flow below the minimum acceptable value.
Select grilles, registers, and diffusers for low static pressure loss,
required throw, and specified air
flow. Choose hardware resistant to
deterioration due to chemicals in
the pool enclosure.
Duct material
The Ecosaire®unit is suitable for
use with any duct material, subject
to the requirements of this section
and standard practice. Standard
galvanized steel duct is recommended.
All elbows must be equipped with
Return Duct
Poor return-duct design can prevent proper
dehumidification by causing uneven air distribution over the evaporator. Reduced
capacity and/or equipment damage may
result.
It is very important to allow straight length
in the return duct as shown. There should
be no elbows, transitions, offsets, or other
flow interruptions closer than 2.5 X WIDTH of
the return duct opening.
If turning vanes are not used in elbows,
allow a length of straight duct equal to at
least 5 X WIDTH.
The straight length is not required for units
with top or bottom return air connections.
aerofoil turning vanes and acoustic
insulation.
Where located in areas below
room temperature, ductwork must
be insulated on the outside with 2
inch fiberglass wrap with FSK facing. All ducts must be designed to
be dry. All seams must be sealed.
Flexible duct connectors
Use flexible duct connectors to
attach the ducts to the Ecosaire
unit. Install the flexible duct in
such a way as to prevent mechanical loads from being applied to the
unit, and to prevent unit vibration
from being transmitted to the ductwork.

IMPORTANT!
The fill-valve orifice is designed for a water
pressure range of 30 to 85 psig (ideally 55 to 60
psig). Contact the factory for water pressures
outside of this range.
INSTALLATION
The humidifier is designed to operate on cold hard
water.
DO NOT connect to a demineralized or distilled
water supply. (Demineralized water will prevent
operation.)
DO NOT use softened water or hot water.
An isolation valve MUST be installed in the supply
line ahead of the humidifier inlet.
Use at least 1/2” copper tube to within four feet of
the Ecosaire® unit. Reduce to 1/4”O.D. and connect
to the 1/4” compression fitting on the supply port as
shown.
IMPORTANT!
Be sure the shut-off valve is closed after the
connections are complete. Do NOT open it until
the humidifier checkout procedure.
The humidifier is equipped with a 7/8” O.D.
unthreaded drain outlet on the underside of the drain
canal on the bottom of the humidifier.
Keep drain lines as short as possible. Keep drain
lines sloped down, not level and not sloped up
since low spots in drain lines will accumulate sediment and cause backup. The drain line should be

Condensate Piping Installation
IMPORTANT!
The condensate drain must be
installed and the P-trap must be
filled before starting the unit.
Location
The condensate drain is a 3/4”
FPT connection in the bottom of the
unit.
Select materials
Ordinary schedule 40 PVC or ABS
plastic pipe is adequate in most
cases. Do not reduce the pipe size
below that provided on the unit.
Install P-trap
If there is no condensate pump, a
drain trap must be installed. The
trap must be at least two (2) inches
deep to maintain a water seal. For
long runs or possible unintentional
traps, a vacuum breaker on the outlet side of the P-trap may be necessary. Follow standard procedures.
Route drain pipe
Route the drain pipe so that the
only trap is the P-trap. In horizontal
runs, slope the pipe downward at
least 1/4” per foot (2 cm per meter).
Deliver the condensate to a suitable point. Check local codes for
allowable procedures.
Fill P-trap
To prevent air from being drawn
through the condensate drain pipe,
the P-trap must be filled with water
before starting the unit blowers.
Failure to do this will cause the
drain pan to overflow during
operation.
Condensate pump
Condensate pumps are available,
with the curve shown below.
If the condensate is to be delivered to a pipe that might be pressurized above atmospheric pressure, install a check valve to prevent backflow.

INSTALLATION
Ecosaire® unit, condenser, and tubes must be evacuated to a pressure below 500
microns of mercury as measured by an electronic vacuum gauge. Compound gauges
as found on refrigeration manifolds are inadequate.
IMPORTANT!
Under no circumstances use the compressor as a vacuum pump or apply power to a compressor under
vacuum. Damage to the motor windings will result.
Connect a good set of refrigeration service gauges, an electronic micron-level vacuum gauge, and a vacuum pump
as shown below. Use core-removal adapters to remove the cores from Schraeder-type access valves.
To insure a correct vacuum reading, install the electronic vacuum gauge far away from the vacuum pump
or use a reliable vacuum valve to isolate the gauge and system from the pump while reading the vacuum.
Colder ambient temperatures require longer evacuation times. Allow enough time at low pressures to remove any
water from the tubes. The triple-evacuation method can be helpful.
After proper evacuation, break the vacuum with vapor refrigerant until a positive pressure is reached.
Replace the access valve cores and remove the adapters.

IMPORTANT:
Contact the factory before using
a flow rate or temperature outside the ranges in the chart
INSTALLATION
below.
IMPORTANT:
Never allow dirt or other foreign
materials to enter the tubes connecting to the
Ecosaire®unit. Foreign
material may cause damage to
valves and other components.
If the inside of the tube is contaminated with dirt, oil, sludge, rust, or
other materials, then the pipes must
be thoroughly cleaned.
Where connection must be made
to metal tube other than copper
tube, install a dielectric union
between the different tubes to
reduce corrosion.
If tubes are silver-soldered, the
inside of the tube must be
protected from oxidation by
flooding the tube with an inert
gas such as nitrogen, argon, or
carbon dioxide. Silver soldering
copper tubes with air inside will produce a flaky copper oxide scale that
can contaminate the system and
damage components.
If flux must be used, use only
enough flux to solder. Excess flux
can contaminate the heat transfer
fluid.
IMPORTANT:
Constant water flow is essential.
All pumps, cooling towers, fans,
etc., involved in cooling the water
must be enabled whenever the
Ecosaire®unit is operational. Do
not allow a timer or other device
to inhibit operation at any time
the Ecosaire®unit is operational.
IMPORTANT:
Cooling water must be
protected from freezing if the
water flow could be interrupted
during low ambient temperatures.
Water-Pressure Switch
The flow-pressure switch must be
adjusted at installation. Adjust the
switch to close as the flow rate
approaches normal and to break as
the flow rate decreases to less than
1/2 of normal.
Condenser water pipes must be
sized to deliver the required condenser water flow. Pipe size is

Glycol Piping Installation
Glycol-Cooled Direct-Expansion, Glycol-Cooled DualCool, & FreeCool Units Only
On the remote
DryCooler, mount the
pump to its mounting plate
and mount the asembly
between the cooler legs.
An installer trained in
the application of closedloop systems should perform glycol-pipe size
selection. Improper pump
and/or glycol pipe selection can result in excessive noise, inadequate
solution flow or premature
pipe and pump impeller
erosion.
Glycol piping should be
installed according to
standard practice. The
factory-supplied expansion tank should be
installed upstream of the
pump. The air purger and
automatic float-type air
vent should be installed
downstream of the pump ideally at the system high
point. If not, manual or
automatic air vents must
be installed at the high
point along with the fill
funnel. Air vents must
upward in the direction of
flow to prevent trapping
air.
Insulate the pipes where
they run through conditioned spaces if the water
temperature is likely to
drop below room-air dew
point.
Install temperature
gauges (or wells), pressure gauges, valves, and
pipe unions according to
the factory piping diagrams.
Install a fill port at the
highest point of the system. To insure proper glycol/water ratio, never use
automatic fillers.
Where copper tubing
(use Type L only) is used,
joints should be hard soldered.
The inlet header is connected to the top of the
condensers and the outlet
header to the bottom.
FreeCool units include

each joint with soap solution or perform a pressure-drop vs. time test.
After testing, the system can be
charged with the glycol/water mixture.
First, determine the proper water-toglycol mixture to provide adequate
freeze protection in your area. This
may already have been determined
by a consulting engineer. Do not
exceed the recommended glycol concentration for your area since
increased concentrations reduce heat
exchange efficiency. These concentrations and corresponding freeze
temperatures are listed in the table
included here.
IMPORTANT!
Use only an inhibited ethylene
glycol suitable for HVAC applications, such as Dowtherm SR-1 or
equivalent. DO NOT use automotive antifreeze since it may damage components.
All glycol-cooled and FreeCool
data is based on forty-percent glycol by volume.
If possible use a pre-mixed
glycol/water solution. Where this is
not possible, mix the solution by volume in a clean non-galvanized container.
Open the fill valve and all air vents,
including the petcocks at the top of
the FreeCool coils on the right-hand
side of the unit. The pipe plugs on
the pump impeller housing and at the
top of the room unit inlet and outlet
headers should be carefully loosened
to permit air to escape. Do not

Chilled-water Piping Installation
Chilled-Water and DualCool Units Only
Chilled Water
Chilled-water piping must be sized to deliver the required water flow. Pipe size is determined by the available
water pressure, pressure drop within the pipe and unit, length of run, maximum velocity, water temperature and
flow requirements. See the table for capacity and flow-rate data for 45°F entering water at typical computerroom conditions.
Chilled-water connections are FPT and are the same size as the chilled-water valve for both the inlet and outlet. A shut-off valve (by others) should be installed on the the inlet and outlet line.
Insulate the chilled-water lines where they run through conditioned spaces if the water temperature is likely to
drop below the space dew point.

INPUT - FIRE ALARM
For units requiring a fire-alarm interlock, remove the
jumper between terminals 300 and 302, or as shown on
the unit wiring diagram. In the jumper’s place substitute an
isolated normally-closed switch closure from the fire alarm
(by others).
If the fire alarm is triggered, the resulting open circuit
between these terminals will cause the Ecosaire® to shutdown.
OPTIONAL EMERGENCY POWER INPUT
Some installations may use the optional emergency power
input. In this case, an open circuit on the input will register
an alarm and will cause the number of operating Ecosaire®
units in a group to be reduced to a predefined number to
reduce the load on the emergency generator.
Note that a reduction in number of operating units may
allow room temperature and humidity to go outside the

The remote air-cooled heat-exchanger con-
trols must be wired to the Ecosaire® controls (see unit
wiring diagram). The remote heat exchanger has its own
power supply.
Some condensers may require the use of Class 1 Remote
Control and Signalling Circuit wiring methods.
The Ecosaire® dry contacts are rated 5A at 24VAC 60Hz.
Do not overload these outputs. Do not attempt to use an
internal Ecosaire® power source.
The condenser control-wire size must be selected to
allow for contactor coil inrush currents. See the chart at
right. Alternatively, a pilot relay (by others) may be installed.
In some cases temperature switches inside the remote
condenser may have to be adjusted.

Humidifier (if any)
Some units may be equipped

Access the humidifier as shown in
the diagram below.
IMPORTANT!
The electrode plugs on top of
the cylinder must be pressed firmly
onto the electrode pins. If a plug is
loose, temporarily disconnect electric power and squeeze the plug
with pliers. Loose plugs will
cause overheating and prossible
melting of the plugs.
Components burnt due to loose
STARTUP
connections are not covered under
warranty.
Open the field-installed shut-off
valve on the water inlet line. Push
the AUTO/ON/OFF/DRAIN switch
to “ON.”
The humidifier light will come on.
The humidifier contactor and the fill
solenoid valve will energize, slowly
filling the cylinder with water. The
water level will rise until the current
draw through the electrodes reaches the pre-set value determined by
the capacity control setting.
Normally, this is before the water
reaches the top.
While the cylinder is filling, locate
the three power leads on the top of
the cylinder and check that the line
voltage is present at all leads.
IMPORTANT!
Low conductivity water will
cause the water level to rise to
the top of the cylinder activating
the High Water Level alarm light.
This is NOT a concern. The
cylinder will continue to heat,
boil and refill in short cycles
until the mineral concentration
within the cylinder increases to
normal. As it does, the water
level will also drop to normal.
The water cylinder will begin to
boil shortly after it stops filling. As
the water boils away, the water
level in the cylinder will drop.
When it has dropped a preset
amount, the fill valve will open to
refill the cylinder. Optimum conductivity is automatically maintained with short drain cycles only
when necessary.
Check the current on all power
lines to the cylinder. The current
will vary with water level. The maximum current will be reached just
as the fill valve closes and should
agree with the nominal amps listed
below.
Should normalization of the unit
be required immediately after startup, the installer may speed up the
process by artificially increasing
water conductivity. During a fill
cycle, the installer should dissolve
half a teaspoon of table salt (NO
MORE) in a cup of water and add it
to the cylinder by means of the fill
cup attached to the plumbing section.
Open the plumbing compartment
and add salt solution through the
cylinder outlet. Excessive amounts
of salt will result in erratic operation
of the unit; however, normalization
of the unit will occur automatically
through the solid-state control
sequence.

The evaporator superheat must be adjusted at startup. It should be 12°F ± 2°F

The temperature sensors and pressure gauges were connected under Startup - Prepare to Adjust TXV.
C)1. Adjust the set points to cause a compressor to operate for at least 15 minutes.
2. Be sure the refrigerant sight glass shows all liquid. If bubbles are present, additional refrigerant may be needed.
3. Read the temperature of the suction tube by the temperature sensor.
4. Read the suction pressure. NOTE: The expansion valves cannot be adjusted if the suction pressure
is over 85 psig. Decrease the room temperature and start over.
5. Use the chart below to determine the suction saturation temperature.
6. Subtract the suction saturation temperature from the temperature sensor temperature.
7. Adjust the expansion valve to cause the difference in step 5 to be 12°F ± 2°F (6°C ±1°C).
8. Repeat steps 1 through 7 for a other refrigerant circuit, if any.
9. When the room temperature reaches 68°F (20°C) to 73°F (23°C), run the unit for an additional 15 minutes, then

Ex:
After 15 minutes, the conditions are
as shown at right.
As shown at left, a suction pressure of
75 psig corresponds to about 44°F
(6.7°C) saturation temperature.
Subtracting 44°F (6.7°C) from the
62°F (16.7°C) measured by the thermocouple yields a difference of 18°F
(10°C).
Since this is more than 12°F (6.7°C),
the expansion valve should be opened
a little by removing its cap and turning
its stem counter-clockwise about 1/2
turn.
Repeat as needed to get about 12°F

Operation Maintenance Schedule
The following list is IMPORTANT to the proper function and long life of the unit.
Every Week
Check for Alarms
· Check that the red alarm light is not activated. If the alarm light comes on at any time, call a service
technician.
Check Room Temperature and Relative Humidity
· Check that the room temperature and relative humidity are within acceptable limits.
Every Month
Check the Air Filters
For units equipped with Dirty Filter alarm, change filters immediately upon alarm, then reset.
· All units have return air filters. The unit cannot work properly with dirty filters.
· All dirty filters should be replaced with identical new filters.
· Do not operate the unit for any amount of time without all filters in place.
Check the Humidifier
· Make sure the strainer is clean.
· If the High Water Sensor light on the humidifier is illuminated (except during startup, see Startup Humidifier), the cylinder must be replaced. For replacement instructions, see Operation Maintenance - Humidifier.
Check the blower belt
OPERATION
· Check for excessive wear. Be sure the belt will operate another month.
· Check the blower belt tension. Belts should not be so loose as to cause increased slip, nor so tight as
to cause excessive shaft bearing wear. See Operation - Maintenance - Blower.
Check that the condensate drain pan(s) is clean.
For units so equipped, check that the remote heat exchanger is clean.
Clean any trash or leaves that might interfere with proper airflow.
Check remote heat exchanger (if any) fan operation.
See Operation - Maintenance - Remote Heat Exchanger.
Every Six Months
For units with mechanical refrigeration, check that there are no bubbles in the sight glass after 10
minutes of compressor operation. See Startup - Adjustments.
Check the evaporator superheat. See Startup - TXV Adjustment.
With the unit disconnect switch open, check that all power connections and terminal screws are tight.
Refer to NEC 110.14 or other applicable codes.
Every Twelve Months
Check for blower bearing wear.
Grease the blower bearings.
· Use a high quality grease for HVAC applications.
· Do not over-grease. Add grease until just a little oozes out from the bearing shield.
Check the condensate drain pan for any accumulated residue. Clean as necessary.
Check the air heat transfer coils for dirt and/or trash.
· If the coils are dirty
-- Clean the coils with a solution of mild soap in warm water. Do not use corrosive cleaning agents.
-- Increase the frequency of filter replacement. Dirty filters leak dirt onto the coils.
In the event of a future shutdown, leave power on the unit for the crankcase heaters if safe to do so. To
start the Ecosaire® unit again, follow the steps in the STARTUP section of this manual.

Belts should not be frayed, glazed, or excessively worn. Follow standard belt inspection procedures recom-
mended by the belt manufacturer.
To check belt tension, first disconnect electric power from the unit and follow all recommended safety precautions. Obtain a V-Belt tension gauge and use it according to the instructions provided with it. Most major belt
manufacturers provide or recommend a suitable gauge for their belts.
In an emergency, the guidelines below may help until a belt tension gauge is obtained.
Measure the distance in inches between
the shaft centers. Multiply the number of
inches by 1/64. This will be the deflection
(D) in the diagram at right.
ex: For S=32 inches,
D= 32in x 1/64 = 1/2 in.
Measure the diameter of the smaller
sheave.
OPERATION
Read the V-belt cross-section size from
the belt label.
Adjust the belt tension to cause the
force needed to produce the deflection D
to be near that shown in the table on the
next page.
ex: For the above example of 32 inches
between shaft centers, assume that
the belt is a new B60 and that the
smaller sheave is 7 inches in
diameter. From the table on the
next page, a new B60 belt with a 7inch small sheave should require
6.3 pounds of force to produce the
1/2 inch deflection.
Adjust the belt tension until the
measured force necessary to produce the
1/2 inch deflection is about 6.3 pounds.

Where sheaves carry more than one belt, never replace only
one belt. If any belt must be replaced, replace all the belts
with new ones. When replacing multiple belts use only new
belts from the same manufacturer and the same lot number, or
use matched belts. Failure to do this will result in severe belt
wear.
When removing or replacing belts, always relieve the belt tension to position the belts. Never prize the belts with a screwdriver or other tool.
Belt sheaves must be properly aligned, as shown below.
Sheave
Straight edge
While the sheaves were aligned at the factory, future adjustments may cause varying degrees of misalignment. A common
problem is parallel misalignment, as shown below. Parallel misalignment causes excessive belt, sheave, and bearing wear.

The steam cylinder is disposable and must be replaced
at the end of cylinder life. Cylinder life is dependent on
left side of unit
water supply conditions and humidifier usage.
HOW TO REMOVE THE STEAM CYLINDER
1. Turn off water supply to unit.
2. Turn off branch circuit disconnect for unit. Take all safety
precautions.
3. The used cylinder must be drained completely before
removal. If the water has just been boiling, allow it to
cool before draining. Push the ON/OFF/DRAIN switch to
the MANUAL DRAIN position. Leave it in this position

just long enough to drain the cylinder (usually less than ten minutes).
4. When completely drained, push the main ON/OFF/DRAIN switch back to the OFF position.
5. Open the acess door.
6. Cylinder plugs are attached to the primary voltage cylinder wires. (The plugs remain attached to the wires
unless they have to be replaced due to damage.) The plugs are press-fitted over the electrode pins
protruding from the top of the cylinder. Remove cylinder plugs from cylinder by pulling vertically.
7. Using a flat screwdriver, loosen the steam hose clamp(s) and pull steam hose off the cylinder vertically.
8. Using a small flat screwdriver, depress the tab on the reusable tie wrap (if present) around the middle of the
cylinder. This will loosen the tie wrap to come apart for re-use later on.
9. Cylinder is now ready to be lifted out of the unit.
CAUTION: Cylinder and any undrained water might still be HOT.
OPERATION
MANDATORY CLEANING OF THE DRAIN VALVE
Always clean the drain valve before installing a new cylinder since the valve port may be as dirty as the used
cylinder.
1. Note that the ring terminal for the drain valve green ground wire is sandwiched between the drain valve body
and the drain pan.
2. Remove two screws securing the drain valve body to the drain pan. Disconnect the two slip-on terminals from
the two tabs on the (24VAC) drain valve coil.
3. Remove the hose clip and hose connection from drain valve body.
4. Drain valve assembly is now free to be taken to a sink for disassembly and cleaning.
5. Remove the snap-fit red cap from coil assembly and slide coil off the actuator.
6. Loosen actuator with wrench and unscrew from the plastic valve body.
7. Clean the exposed core and spring and plastic drain valve port.
8. IMPORTANT! The tapered end of the spring MUST BE INSTALLED TOWARD THE SOLENOID.
Reassemble, tighten the actuator 1/4 turn past hand-tight.
9. Clean out the end of the hose, then reconnect it to the drain valve body with the clamp.
10. Fit mounting screws through the drain valve body, one through the ring terminal on the green ground wire.
11. IMPORTANT! To prevent the possibility of electrical shock the green ground wire must be installed
before the power is restored.
12. Push the two slip-on terminals back onto the two tabs on the coil. The terminals, although not identical, are
reversible.

Humidifier Maintenance Operation
HOW TO INSTALL THE REPLACEMENT CYLINDER
1. Reverse procedure should be followed to install the new cylinder. The branch-circuit disconnect is to be left
open until the cylinder is completely installed and reconnected.
2. Ensure that the cylinder is secured properly by the re-usuable tie wrap and mounting brackets within the unit.
3. The cylinder plug wires are color-coded in accordance with the colored dots beside the electrode pins on top of
the cylinder. This color-coding MUST be adhered to when replacing cylinder plugs on pins.
4. With cylinders having six primary voltage cylinder plugs, it should be noted that there are two of each color.
5. Care MUST be taken so that the cylinder leads of the same color are always directly opposite each other
as indicated by the dot formation on the top of the cylinder.
6. The white cylinder plug on all units is for the sensor electrode which always goes on the single pin surrounded
by a plastic shoulder.
7. Ensure that cylinder plugs fit snugly on the pins.
8. If cylinder plugs become loose, it is best to obtain a new replacement plug.
EXTENDED SHUTDOWN
Before disconnecting power to the humidifier for a period of extended shutdown, ALWAYS DRAIN the cylinder
first. Otherwise, the electrodes are subject to harmful corrosion which drastically shortens cylinder life. DO NOT
leave the switch in the DRAIN position indefinitely as the drain coil could burn out. Leave the switch in the OFF
position and “open” the main external fused disconnect to stop power to the humidifier. Close the shut off valve in
the water supply line feeding the humidifier.
