I. Important Safety Information

SAFETY INSTRUCTIONS

The equipment described in this Manual is designed and manufactured to operate within

defined design limits. Any misuse may result in electric shock, equipment damage, or

fire. To avoid injury and damage, the following rules should be observed for installation,

use and maintenance. Read the following safety instructions before operating the

instrument.

POWER

POWER CORD: Use only the power cord specified for this equipment and certified for the

country of use. If the power (mains) plug is replaced, follow the wiring connections

specified for the country of use. When installing or removing the power plug, hold the

plug, not the cord. The power cord provided is equipped with a 3-prong grounded plug (a

plug with a third grounding pin). This is both a safety feature to avoid electrical shock

and a requirement for correct equipment operation. If the outlet to be used does not

accommodate the 3-prong plug, either change the outlet or use a grounding adapter.

FUSES: Replace fuses only with those having the required current rating, voltage and

specified type such as normal blow, time delay, etc. DO NOT use makeshift fuses or

short the fuse holder. This could cause a shock or fire hazard or severely damage the

instrument.

OPERATION

CAUTION

DO NOT OPERATE WITH COVERS OR PANELS REMOVED. Voltages inside the

equipment consist of line (mains) voltages that can be anywhere from 100 to 240VAC.

DO NOT OPERATE WITH SUSPECTED EQUIPMENT FAILURES. If any odor or smoke

becomes apparent turn off the equipment and unplug it immediately. Failure to do so

may result in electrical shock, fire or permanent damage to the equipment. Contact the

factory for further instructions.

DO NOT IMPEDE THE DEVICE FROM VENTING. The dehumidification system is an open

loop systems that pumps air into the chamber. If the air output is impeded or the

chamber is not allowed to vent, pressure could build up and cause damage.

DO NOT USE IN ANY MANNER NOT SPECIFIED OR APPROVED BY THE

MANUFACTURER: Unapproved use may result in damage to the equipment or present an

electrical shock, injury, or fire hazard.

II. Description of Contents

The Model 5478 Self-Regenerating Dehumidification System is assembled in a 6” W x

9.5” L x 3.5” H (15.25 x 24.1 x 8.5 cm) plastic enclosure with vibration isolating feet. The

power switch and indicator light are both located on the front panel of the enclosure.

Internally, the system consists of a dual tower compressed air dryer (molecular sieve)

and a 3-way solenoid valve to direct the dried air and a flow regulator to control the

output flow. The dryer and valve are installed inside the enclosure.

III. SET-UP GUIDE

Step 1 –Dry Air Output The dry air

output is located on the rear, center of

the unit (with ¼” Quick Connect fitting

and a flow regulator).

Step 2 –Attach Dry Air Tubing

Use ¼” OD tubing between this fitting

and chamber. Insert the tubing firmly to

ensure it is properly sealed and won’t

come loose.

Step 3 –AC supply for circuitry

Power cord #1 is on the left. This

power source stays energized at all

times, Power is supplied to the air dryer,

(100VAC to 240VAC, single phase, 50-

60 Hz)

Step 4 –Controlled AC power input

Power cord #2 is on the right. The AC

power (100VAC to 240VAC, single

phase, 50-60 Hz), is to be connected to

a controlled AC circuit (see below).

When power Is applied, dehumidification

takes place.

Step 5 –Controlled AC power source

This AC line cord is normally plugged in

to the RH DECR outlet of a controller to

dry the chamber.

Step 6 –Connect Air Source. Connect

a Compressed air source to the air input

fitting on the top of the enclosure.

Regulate compressed air to 50 to 100

PSI.

IV. Quick Start Guide

Step 1 -- Turn the Power ON. Turn the

power switch on the front panel to the

right, or “ON” position. The dryer will

begin operating immediately to produce

dry air. Some sounds will be made by

the mechanism –this is normal.

V. Functionality

The Model 5478 Self- Regenerating Dehumidification System is designed to reduce the relative

humidity in a chamber to less than 12% RH. When used with an Automatic Humidity Controller,

the humidity inside the chamber can be controlled to within ± 0.5% RH of the setpoint. Using the

ETS Model 5100 or Model 5200 Microprocessor Humidity Controllers, the chamber may be

maintained to within ±0.1% RH of the set-point.

Operation of the Model 5478 can be controlled manually or by a controller, such as in a

chamber. The system consists of a dual tower compressed air dryer (molecular sieve) and a 3-

way solenoid valve to direct the dried air and a flow regulator to control the output flow. The

dryer and valve are installed inside the enclosure. Desiccant is automatically renewed while the

System is running. The System never has to be shut down to renew or replace desiccant. All

moisture-laden air is evacuated through a muffler inside of the enclosure. When energized, the

solenoid valve allows dried air to flow to the output. The power light on the front panel indicates

when dried air is flowing to the output. The Model 5478 is an open-loop system.

1. The Power switch controls power from both power cords. When the unit is turned on, the

valve and dryer (inside the box) begin to operate immediately.

2. In a controlled system, The Dehumidify Controller activates the 3-way valve. A. When “OFF”,

the dry air being produced is vented inside the box. B. When “ON”, the dry air is directed to the

air output on the rear of the unit.

3. The indicator light (on the front of the unit) indicates when the 3-way valve is “ON”.

4. The 5478 is a Positive Pressure System. The unit will cause a slight positive pressure in an

enclosure if not adequately ventilated.

5. The dryer operates using a house air system at 50 to 100 psi. At 100 psi, twice as much dry

air is produced, reducing drying time.

6. Air is dried to a -40°F pressure dewpoint with 85° to 90°F saturated inlet.

7. The Model 5478 can be used to dry any inert gas @ pressure.

V. Specifications

1. The average flow rate from the unit is 0.30 cfm (7.3 lpm) at 50 psi, 0.83 cfm at 100 psi.

2. The air will be dried to a minimum dewpoint of -40°F with a saturated input at 90°F.

3. Power –115 VAC/60 Hz @ 4.30Amps or less, or 230 VAC/50 Hz @ 2.15Amps or less

4. Working Pressure is 50-100 psig. Dryer unit may be used with compressed air systems up to

120 psig.

5. Dual column dryer uses a molecular sieve desiccant. 6. Output fitting is for ¼” OD tubing.
