InRow Half-Rack RC Installation
Room Preparation
During the design of the data center, consider ease of entry for the equipment, floor loading factors, and
accessibility to piping and wiring.
Seal the room with a vapor barrier to minimize moisture infiltration. (Polyethylene film is recommended
for ceiling and wall applications.) Apply rubber- or plastic-based paints to concrete walls and floors.
Insulate the room to minimize the influence of exterior heat loads. Use the minimum required amount of
fresh air for make up to comply with local and national codes and regulations. Fresh air imposes extreme
load variation on the cooling equipment from summer to winter and causes increased operating costs.
The equipment is designed as a sensible cooling air conditioning unit for in-row use in data centers. The
equipment does not have humidification or dehumidification control. Room humidity must be within
acceptable operating conditions before starting equipment. If operated in spaces where the humidity
is in the unacceptable operating conditions section of the Operating Guidelines chart (see the InRow RC
Operation and Maintenance manual) the equipment condenses excess water vapor from the air. This will
exceed the pumping capacity of the condensate pump, causing the equipment to send an alarm and shut
down to avoid overflowing the condensate pan. The condensate pump runs until the fluid level in the pan
is reduced, and the alarm is automatically reset. The equipment self-regulates in this manner until normal
operating conditions are present.
Note: The InRow RC is not intended to be used in an occupied office environment, due to
potentially high noise levels during peak loads. Install the InRow RC in a computer room
where people are normally present only for maintenance.
Incoming power supply requirements
See the electrical rating label on the equipment to determine the maximum possible current draw of the
equipment. Provide either a single outlet circuit or a Power Distribution Unit (PDU) with sufficient
capacity to handle all loads. Do not plug two InRow RC units into the same branch circuit or PDU.
The equipment must be grounded. Electrical service must conform to national and local electrical codes
and regulations.

See “Piping Diagrams,” beginning on page 8, for recommended valve, flexible adapter, and
strainer installation locations.
1. Route all piping  to the InRow RC in compliance with all local and national codes.
Note: Circuit setters are required to regulate the flow of chilled water to each piece of
equipment. When a CDU is used in conjunction with the equipment, circuit setters are
not required, as the CDU provides the flow-regulating function.
Note: The figure shows a top piping installation with a PEX fitting. Bottom piping
installations or rigid piping fittings are handled similarly.
2. Disassemble the union on the entering or exiting water line:
a. Remove the nut  from the body .
b. Remove the disc  and gasket . Save the gasket.
c. The disc  prevents water flow through the union.
Discard the disc .
3. Repeat step 2 for the union on the other water line.
4. Assemble the union on the entering or exiting water line:
a. Use thread sealant and thread sealing tape in accordance
with local and national codes.
b. Slide the nut  onto the fitting .
c. Seat the gasket  into the body .
d. Tighten the body  onto the nut , using a properlysized open end wrench.

Condensate pump. The pump is factory-wired and piped
internally to the lower condensate pan. The pump is capable of
moving liquid a maximum of 15.2 m (50 ft), including a
maximum lift of 4.9 m (16 ft). For example, if your lift is 3 m
(10 ft), you have 12.2 m (40 ft) of usable run. The pump also
uses an on-board condensate high level float switch, which is
wired into the InRow RC alarm input for local
and remote alarm capabilities.

Feeds A and B. The equipment is capable of receiving power through one of two separate feeds, feed
A or feed B. Use the display interface to configure the unit to receive power through feed A, feed B, or
both). If connected, feed B is the primary power input to the equipment by default; feed A is the backup
power input. The equipment receives power through feed B regardless of whether feed A is receiving
power. If power is removed from feed B, feed A takes over and supplies power to the equipment (if feed
A is connected). Connect the feed A and feed B cables to individual, breaker-controlled branch circuits
or to PDUs backed by separate Uninterruptible Power Supplies (UPSs).
Note: Feed A and feed B must not use the same branch circuit, PDU, or UPS.
For more information on configuring power input feeds, see the InRow RC Operation and
Maintenance manual.

Form C alarm contacts and shutdown input
A relay internal to the user interface is typically controlled by a user-defined alarm (malfunctioning fans,
for example). Before an alarm is detected, the voltage on the COM terminal is routed to the NC terminal.
When the alarm is activated, the relay is energized, causing the voltage on the COM terminal to be
routed to the NO terminal. The NO and NC terminals may be connected to remote indicator lights, a
warning buzzer, or another device to alert an operator to the presence of an alarm condition.
A remote disconnect switch may be connected to the shutdown inputs.

position of the rack temperature sensors will vary from installation to installation, but should be
located in the airflow to allow accurate readings.
Servers most likely to have insufficient air or inadequately cooled air due to the recirculation of
hot air from the hot aisle include:
a. Servers positioned at the top of a rack.
b. Servers positioned at any height in the last rack at an open end of a row.
c. Servers positioned behind flow-impairing obstacles such as building elements.
d. Servers positioned in a bank of high-density racks.
e. Servers positioned next to racks with Air Removal Units (ARU).
f. Servers positioned very far from the equipment.
g. Servers positioned very close to the equipment.
