Service Manual or Service Request

We are looking for a service manual to perform a PM on a Tosoh G8 HLC-723G8 or alternatively if we are looking for someone that can perform this in the filed. The customer is located in Irvine California. Tosoh no longer performs this service as this unit has been purchased from a company down the hall. If anybody knows of a company that can do this service or anybody has the service manual or procedure please let us know at support@medrun.com We really appreciate it.
