2. I  Receiving Inspection

SECTION II 

INSPECTION 

Prior  to  using  your  controller  for  the  first  time,  remove  tJ:ie  two  screws  of  the  upper 

corners of  the  rear  panel  and  take  off  the  top  cover.  Visually inspect the unit  for  shipment 

damage.  Especially  check  to  see  that  all relays  are  seated in their  sockets properly, that the 

relay  retaining straps are  in place,  that the  inter-connect cable between the two P.C.  boards 

is  properly  seated,  that  the  line  voltage  selector  switches  are  in  the  proper  position  and 

finally  that  the  proper  fuse  is  provided.  Following  these  preliminary  inspection  steps  may 

save  substantial  time  delays  in  putting  your  new  unit  into  operation  in the  event  of shipping 

damage or human error. 

2.2  Domestic Shipments 

Confirm  that  your  shipment  includes  all material and options ordered.  If materials  are 

missing  or  damaged  the  carrier  that  made  the  delivery  must  be  notified  within  15  days  of 

delivery  in  accordance  with  Interstate  Commerce  regulations  in  order  to  file  a  valid  claim 

with  the  carrier.  Any  damaged  material  including  all  containers and  packing should  be  held 

for  carrier  inspection.  Contact  our  Customer  Service  Department,  5675  East  Arapahoe 

Avenue,  Boulder, Colorado  80303,  (303)  443-7660  if your  shipment  is not correct  for  reasons 

other than shipping damage. 

2.3  International Shipments 

If  items  are missing  or damaged the carrier making delivery to  the customs broker must 

be notified within  15  days of delivery. 

Example: 

If an airfreight  forwarder  handles  the  shipment and their  agent delivers the shipment to 

customs the  claim must be filed with the airfreight forwarder. 

If  an  airfreight  forwarder  delivers  the  shipment  to  a  specific  airline  and  the  airline 

delivers  the  shipment  to  customs  the  claim  must  be  filed  with  the  airline,  not  the 

freight  forwarder. 

Any  damaged  material  including  all  containers and  packaging  should  be  held  for  carrier 

inspection.  Contact our Customer Service  Department,  5675  East Arapahoe Avenue,  Boulder, 

Colorado  80303,  U.S.A.  Telex  045  791  GPVAC  Bldr  or  telephone  (303)  443-7660  if  your 

shipment is not correct for reasons other than shipping damage.
