INTRODUCTION

These instructions cover installation of 30HX liquid chillers
with electronic controls and units with factory-installed options
(FIOPs).

INSTALLATION

Step 1 - Inspect Shipment -

age upon arrival. If damage is found, immediately file a claim
with the shipping company. Verify proper unit delivery by
comparing the model number on the nameplate with the data in
Fig. 1. Do not store units in an area exposed to weather because
of sensitive control mechanisms and electronic devices.

Locate unit indoors. When considering unit location, con-
sult National Electrical Code (NEC, U.S.A.) and local code
requirements. Allow sufficient space for wiring, piping, and
service. Install unit in an area which will not be exposed to am-
bient temperatures below 50 F (10 C). See Fig. 2-10 for clear-
ance details.

Be sure surface beneath unit is level and is capable of
supporting the operating weight of the unit. See Fig. 11 and 12
and Tables 1A and 1B for unit mounting and operating
weights. If necessary, add supporting structure (steel beams or
reinforced concrete slabs) to floor to transfer weight to nearest
beams.
