Pre-Installation
Receiving Inspection
When the unit arrives, verify the information on the
unit nameplate agrees with the order
acknowledgement and shipping papers. Inspect the
equipment for any visible damage and verify all
items shown on the bill of lading are present. If
damage is evident, document it on the delivery
receipt by clearly marking any item with damage as
“unit damage” and notify the carrier. In addition,
notify our Customer Service Department and they
will provide assistance with preparing and filing
freight damage claims, including arranging for an
estimate on repair costs; however, filing the shipping
damage claim is the responsibility of the receiving
party. Do not install damaged equipment without
getting the equipment repaired.
Shipping damage is the responsibility of the carrier.
To protect against possible loss due to damage
incurred during shipping and to expedite payment
for damages, it is important to follow proper
procedures and keep records. Photographs of
damaged equipment are excellent documentation
for your records.
Start unpacking the unit, inspect for concealed
damage, and take photos of any damage found.
Once received, equipment owners have the
responsibility to provide reasonable evidence that
the damage did not occur after delivery. Photos of
the equipment damage while the equipment is still
partially packed will help in this regard. Check for
broken lines, oil leaks, damaged controls, or any
other major component torn loose from its
mounting point.
Record any signs of concealed damage and file a
shipping damage claim immediately with the
shipping company. Most carriers require concealed
damages be reported within 15 days of receipt of
the equipment. In addition, notify our Customer
Service Department and they will provide assistance
with preparing and filing freight damage claims,
including arranging for an estimate on repair costs;
however, filing the shipping damage claim is the
responsibility of the receiving party.
Unit Storage
When storing the unit it is important to protect it
from damage. Blow out any water from the unit;
cover it to keep dirt and debris from accumulating
on or getting in and store in an indoor sheltered
area that does not exceed 145°F.
Installation - Mechanical
Foundation
Install the unit on a rigid, non-warping mounting
pad, concrete foundation, or level floor suitable to
support the full operating weight of the equipment.
When installed the equipment must be level within
¼ inch over its length and width.
Unit Location
The unit is available in many different configurations
for various environments. Refer to the proposal and
order acknowledgement document for the
equipment to verify the specific design conditions in
which it can operate.
To ensure proper airflow and clearance space for
proper operation and maintenance allow a minimum
of 12 inches of clearance between the sides of the
equipment and any walls or obstructions. Avoid
locating piping or conduit over the unit to ensure
easy access with an overhead crane or lift to lift out
heavier components during replacement or service.
Rigging
Pumps decks and reservoir systems typically have a
structural steel frame to facilitate easy movement
and positioning. Follow proper rigging methods to
prevent damage to components. Avoid impact
loading caused by sudden jerking when lifting or
lowering the reservoir. Use pads where abrasive
surface contact may occur. Use the frame supporting
the unit for positioning it with a crane or a forklift.

3
Water Piping
Proper insulation of chilled process fluid piping is
crucial to prevent condensation. The formation of
condensation adds a substantial heat load to the
cooling system.
The importance of properly sized piping cannot be
overemphasized. See the ASHRAE Handbook or
other suitable design guide for proper pipe sizing. In
general, run full size piping out to the process and
then reduce the pipe size to match the connections
on the process equipment. One of the most
common causes of unsatisfactory unit performance
is poor piping system design. Avoid long lengths of
hoses, quick disconnect fittings, and manifolds
wherever possible as they offer high resistance to
water flow. When manifolds are required, install
them as close to the use point as possible. Provide
flow-balancing valves at each machine to assure
adequate water distribution in the entire system.
Install shut-off valves at each machine to allow for
isolation of the unit.
CAUTION: Do not use the reservoir as a means of
supporting piping. Supporting piping on the reservoir
can result in fiberglass fractures, sidewall stresses, and
piping deflections that could develop into a leak or a
complete loss of the water reservoir structural
integrity.
Installation - Electrical
All wiring must comply with local codes and the
National Electric Code. Minimum circuit amps (MCA)
and other unit electrical data are on the unit
nameplate. A unit specific electrical schematic ships
with the unit. Measure each leg of the main power
supply voltage at the main power source. Voltage
must be within the voltage utilization range given on
the drawings included with the unit. If the measured
voltage on any leg is not within the specified range,
notify the supplier and correct before operating the
unit. Voltage imbalance must not exceed two
percent. Excessive voltage imbalance between the
phases of a three-phase system can cause motors to
overheat and eventually fail. Voltage imbalance is
determined using the following calculations.
%Imbalance = (Vavg – Vx) x 100 / Vavg
Vavg = (V1 + V2 + V3) / 3
Vx = phase with greatest difference from Vavg
For example, if the three measured voltages were
442, 460, and 454 volts, the average would be:
(442 + 460 + 454) / 3 = 452
The percentage of imbalance is then:
(452 – 442) x 100 / 452 = 2.2 %
This exceeds the maximum allowable of 2%.
There is a terminal block for main power connection
to the main power source. The main power source
should be connected to the terminal block through
an appropriate disconnect switch. There is a separate
lug in the main control panel for grounding the unit.
Check the electrical phase sequence at installation
and prior to start-up. Operation with incorrect
electrical phase sequencing will result in mechanical
damage to components. Check the phasing with a
phase sequence meter prior to applying power. The
proper sequence should read “ABC” on the meter. If
the meter reads “CBA”, open the main power
disconnect and switch two line leads on the line
power terminal blocks (or the unit mounted
disconnect). Do not interchange any load leads that
are from the unit contactors or the motor terminals.
WARNING: This equipment contains hazardous
voltages that can cause severe injury or death.
WARNING: This equipment may contain fan blades or
other sharp edges. Make sure all fan guards and other
protective shields are securely in place.
WARNING: The exposed surfaces of motors, piping,
and other fluid circuit components can be very hot
and can cause burns if touched with unprotected
hands.
CAUTION: Disconnect and lock out incoming power
before installing, servicing, or maintaining the
equipment. Connecting power to the main terminal
block energizes the entire electric circuitry of the unit.
Electric power at the main disconnect should be shut
off before opening access panels for repair or
maintenance.
CAUTION: Wear eye protection when installing,
maintaining, or repairing the equipment to protect
against any sparks, debris, or fluid leaks.

CAUTION: Wear protective gloves when installing,
maintaining, or repairing the equipment to protect
against any sparks, debris, or fluid leaks.
CAUTION: Wire the unit ground in compliance with
local and national codes.
