HANDLING THE DRYER SECTION 1
1.1 HANDLING INSTRUCTIONS
WARNING
DO NOT LIFT THE DRYER BY THE INLET PIPING OR CONTROL
BOX. THESE COMPONENTS ARE NOT DESIGNED TO HOLD 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 INSTRUCTIONS 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 applicable 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 NATURAL GAS 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
WHEN INSTALLING AND OPERATING THIS EQUIPMENT,
COMPLY WITH THE NATIONAL ELECTRICAL CODE AND
ALL APPLICABLE FEDERAL, STATE, AND LOCAL CODES.
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.
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.
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.)
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 SOLENIOD
VALVES) WITH CHICO COMPOUND AND CHICO FIBER TO ENSURE THE INTEGRITY OF THE EXPLOSION PROOF RATING.
PAGE 2
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.
