HANDLING SECTION 1

1.1 HANDLING INSTRUCTIONS

WARNING

DO NOT LIFT THE DRYER BY THE INLET PIPING (BELOW
VESSELS). THIS PIPING IS NOT DESIGNED TO SUPPORT THE
WEIGHT OF THE DRYER. PERSONAL INJURY AND/OR EQUIP­MENT DAMAGE MAY RESULT.

Lift the dryer by the outlet piping (above vessels).

When lifting the dryer, make sure that the chains or cables are clear of
all tubing and fragile components.

If outside storage is required, the unit MUST BE adequately covered to
prevent rain or snow from accumulating on the dryer. The unit must be
placed on a paved surface to keep it out of standing water and mud.

1.3 EQUIPMENT CHECK

Inspect the dryer for any damage that may have occurred during ship-

ment. Inspect all ttings, piping connections, fasteners, etc. for loose

connections. Also check gauges and lights for cracks or breakage.

IF DRYER HAS BEEN DAMAGED DURING SHIPMENT:

(1) NOTIFY CARRIER IMMEDIATELY AND FILE A CLAIM.
(2) CONSULT FACTORY BEFORE OPERATING THE DRYER.

1.2 STORAGE INSTRUCTIONS

The unit should be stored indoors and covered with a tarpaulin to
keep it clean. The location should be free from corrosive gasses and
extreme humidity, which will cause damage to the unit.

SAFETY SECTION 2

2.1 HANDLING

LIFT THE DRYER BY THE OUTLET PIPING (ABOVE THE VES­SELS) AS THE OTHER COMPONENTS ARE NOT DESIGNED
TO SUPPORT THE WEIGHT OF THE DRYER.

LIFTING BY OTHER COMPONENTS MAY CAUSE PERSONAL
INJURY AND/OR EQUIPMENT DAMAGE.

2.2 INSTALLATION

BEFORE STARTING INSTALLATION PROCEDURES, TURN
OFF POWER TO THE AREA WHERE THE DRYER WILL BE IN­STALLED. SERIOUS PERSONAL INJURY MAY RESULT IF THIS
SAFETY RULE IS NOT FOLLOWED.

DO NOT REMOVE, REPAIR, OR REPLACE ANY ITEM ON
DRYER WHILE IT IS PRESSURIZED.

THESE ASME CODE VESSELS MUST BE PROTECTED BY
PRESSURE RELIEF VALVES. Refer to OSHA 1910.169 Par.
b, Sub. Par (3) and ASME Boiler and Pressure Vessel Code,
Section VIII, Division 1, UG-125 through UG-136. Also com­ply with all state and local codes.

WHEN INSTALLING AND OPERATING THIS EQUIPMENT, COM­PLY WITH THE NATIONAL ELECTRICAL CODE AND ALL AP­PLICABLE FEDERAL, STATE, AND LOCAL CODES.

2.3 OPERATION

DO NOT OPERATE DRYER IF EITHER OF THE VESSELS IS
LEAKING. IMMEDIATELY TAKE THE DRYER OUT OF SERVICE.

DO NOT OPERATE THIS DRYER ABOVE THE MAXIMUM RATED
WORKING PRESSURE.

NOTE
OPERATING CONDITIONS FOR PROPER PERFORMANCE OF
THIS DRYER ARE DIFFERENT FROM MAXIMUM OPERATING
CONDITIONS FOR THE VESSELS. BE SURE TO CHECK THE
DRYER OPERATING CONDITIONS. SEE SECTION 3.1

USE THIS DRYER FOR COMPRESSED AIR ONLY.

DO NOT OPERATE THIS DRYER IF EITHER VESSEL HAS
BEEN DAMAGED BY FIRE. TAKE OUT OF SERVICE IMMEDI­ATELY AND NOTIFY YOUR CERTIFYING AUTHORITY.

2.4 MAINTENANCE

DO NOT REMOVE, REPAIR, OR REPLACE ANY ITEM ON
THE DRYER WHILE IT IS PRESSURIZED. TURN OFF MAIN
POWER TO THE DRYER AND DEPRESSURIZE THE DRYER
COMPLETELY BEFORE STARTING MAINTENANCE PROCE­DURES.

ALWAYS WEAR EYE PROTECTION, GLOVES AND A
RESPIRATORY PROTECTIVE DEVICE WHEN HANDLING THE
DESICCANT. DESICCANT DUST MAY CAUSE EYE AND
SKIN IRRITATION. AVOID BREATHING THE DUST AND
PROLONGED CONTACT WITH THE SKIN.

FIRST AID IN CASE OF EYE CONTACT WITH DESICCANT
DUST; IMMEDIATELY FLUSH THE EYES WITH PLENTY
OF WATER FOR AT LEAST 15 MINUTES. CONSULT A
PHYSICIAN.

IT IS CUSTOMER'S RESPONSIBILITY TO FILL ALL CONDUIT SEAL
FITTINGS (INCLUDING THE ONES TO THE SOLENOID VALVES)
WITH CHICO COMPOUND AND CHICO FIBER TO ENSURE THE
INTEGRITY OF THE EXPLOSION PROOF RATING.

PAGE 2

DO NOT WELD OR GRIND THE VESSELS. THEY WILL NOT
BE SAFE TO OPERATE. (Note: Any uncertified alteration to
the vessels VOIDS the ASME Code Certification.)

INSPECT OUTSIDE AND INSIDE OF VESSELS REGULARLY
FOR CORROSION AND DAMAGE (I.E. DENTS, GOUGES OR
BULGES). ANY DAMAGE TO THE VESSELS CAN MAKE
THEM UNSAFE TO USE. IF DAMAGED, TAKE OUT OF SER­VICE IMMEDIATELY.
