GENERAL

INTRODUCTION

These instructions are for Hobart HP/HR/HPR,

BXP/BXR/BXPR Series Proofer/Retarder. Certain

steps may only apply to HP Series, HPR Series or

HR Series and will be indicated as such. The

HP1/HPR1, BXP1/BXPR1 single wide

proofer/retarder can be shipped assembled requiring

minimal field assembly. All proofer/retarder can be

shipped unassembled requiring field assembly. Both

shipping methods will require leveling and

connection to utilities.

All information, illustrations and specifications

contained in this manual are based on the latest

product information available at the time indicated on

the cover of the manual.

UNPACKING

Remove the crating from proofer/retarder and check

for possible shipping damage. If the proofer/retarder

is found to be damaged after uncrating, save

packaging material and contact the carrier within 15

days of delivery.

If location has multiple proofer/retarders, keep serial

numbered crates together.

Check contents against packing list (included) with

shipment.

LOCATION
