PART 3 — EXECUTION
3.1 GUIDELINES FOR INSTALLATION
A. GENERAL
1. The InRow RC provides reliable, accurate temperature control of computer rooms, laboratories,
and other environments that require close tolerance control. The unit incorporates the latest system
design innovations to provide you with optimum efficiency, reliability, and accuracy of control.
2. The InRow RC unit will provide years of trouble-free service, when installed and maintained by
technically qualified personnel. For more detailed information, see the InRow RC Installation
Manual, 990-4705.
B. ROOM PREPARATION
1. During the design of the room, consideration should be given to the following factors:
a. Ease of entry for the system, floor-loading factors, and accessibility of piping and wiring.
b. The room must be sealed with a vapor barrier to minimize migration of moisture.
c. Polyethylene film (plastic sheeting) is a good vapor barrier for ceiling and wall applications.
d. Rubber-based or plastic-based paints should be applied to concrete floors and walls.
e. The room should be thoroughly insulated to minimize thermal loads and make-up air (if
required) should be preconditioned to reduce additional temperature, filtration, and moisture
loads.
C. SERVICE ACCESS
1. At least 914.4 mm (36 in.) of clear space must be left in front of and behind the unit for routine
service. In order to service the unit outside of the row, an area of 1219.2 mm (48 in.) of clear space
is required in front of and behind the unit while it is in the row.
D. RECEIVING THE UNIT
1. Your InRow RC unit has been completely tested and inspected before shipment. To ensure that you
have received the unit in excellent condition, perform a careful inspection of the crating and the
unit immediately upon receipt.
2. Verify that all parts ordered were received as specified and that the unit is the correct size and
voltage necessary to fulfill your environmental control needs.
3. Report any damage discovered to the freight carrier.
4. If necessary, contact the Schneider Electric field service department for help in repairing or
replacing damaged parts. While Schneider Electric is not responsible for damage incurred in
transit, we want to make sure that you have no undue delays in your system start-up.
E. RIGGING
1. The unit is manufactured with a formed steel frame for maximum strength and unit integrity.
However, as with all electrical and mechanical equipment, you must take care with proper rigging
of your unit.
