INTRODUCTION
This document contains general installation instructions for
the 40UV,UH unit ventilators and information and trouble-
shooting of the Product Integrated Control (PIC) option.

PREINSTALLATION
Unpack and Inspect Units
Remove shipping wraps
from all units. Check the shipment against shipping order. If
shipment is damaged or incomplete, file claim with transporta-
tion company and advise Carrier immediately.
Protect Units From Damage To maintain war-
ranty, protect units against adverse weather, theft, vandalism,
and debris on jobsite. Do not allow foreign material to fall into
drain pan. Prevent dust and debris from being deposited on
motor and fan wheels.
If the equipment is stored for any length of time before in-
stallation, it should remain in its shipping container in a clean,
dry, and climate controlled area.
Prepare Jobsite for Unit Installation To save
time and to reduce the possibility of costly errors, set up a com-
plete sample installation in a typical room at jobsite. Check all
critical dimensions such as pipe, wire, and duct connection
requirements. Refer to job drawings and product dimension
drawings as required. Instruct all trades in their part of the
installation.
Before performing service or maintenance operations, turn
off main power switch to the unit. Electrical shock could
cause personal injury.
