SAFETY CONSIDERATIONS

Installation and servicing of this unit can be hazardous due

to system pressure, electrical components and equipment
location (such as a ceiling or elevated structure). Untrained
personnel can perform the basic maintenance functions of
replacing filters. Only trained and qualified service personnel
should perform all other operations.

When installing this unit, observe precautions in the litera-

ture, tags and labels attached to the equipment, and any other
safety precautions that may apply.
•

Follow all safety codes.

•

Wear safety glasses and work gloves.

•

Use care in handling and installing this accessory.

•

Use quenching cloth for all brazing operations.

•

Have fire

extinguisher available for all brazing

operations.

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.

See submittal drawings for unit configurations, dimensions,

clearances, and pipe connections. Refer to unit wiring label for
all electrical connections; follow NEC (National Electrical
Code) and local codes.

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.
