C. STORAGE
All radiators are prime painted and top coated prior to being shipped unless a special
finish is specified.
When the radiator is not going to be used immediately and is to be stored, it should be
kept in a clean, dry place, not subject to rapid change in temperature or humidity and
away from heavily traveled areas to avoid the possibility of damage.
To prevent premature drying of gaskets, avoid storage of the radiator outdoors for long
periods of time in direct sunlight, in temperatures above 90°F and relative humidity
below 50%.
For outdoor storage, covering the radiators is recommended. This will provide protection
from weather and elements. For indoor storage, covering is not mandatory, however,
radiators should be kept away from areas where airborne particulates or contaminates
may affect the cosmetics/integrity of the product (i.e. grinding, painting, chemicals,
etc.).
A water-soluble fogging in the radiator tanks will help provide some protection to
prevent gaskets becoming dry and brittle and can coat interior surfaces to prevent
premature surface rusting.
For radiators that include motors or fan shaft bearings, rotate the shafts several turns,
once per month, to redistribute the grease in the bearings.
D. MOVING AND LIFTING
When the radiator is moved from the receiving area, use the following recommended
procedures:
It is recommended that the radiator remain on its skid and be moved with a forklift.
The small horizontal radiators may be shipped in the horizontal position, but the larger
horizontal radiators may be shipped in the vertical position. In this case, extreme
caution must be taken when lifting and rotating the radiator from the vertical to
horizontal position (See Fig. 1A), because the weight will shift as it is being rotated. Use
the following procedure:
1. While lifting, hold the lower legs in place. While continuing to lift, move the lifting
points in the direction of the lower legs (pivot point).
2. While rotating, the weight of the unit will shift when the center of gravity moves
from one side of the pivot point to the other side.
3. When the radiator is resting on all (4) legs, it can now be lifted as shown in
Figure 1B
When a forklift is not available, and for final lifting and placement of the radiator, lifting
holes are provided near the top of both sidemembers on vertical radiators, and at the
ends of both sidemembers (4 corners) on horizontal radiators (See Fig. 1B). Refer to
the radiator assembly drawing for more exact lifting hole locations.

E. SAFETY AND ADVISORY MESSAGES
1. WARNING! Vertical radiators are
subject to wind effects and installation
should consider the potentially
dramatic effect of prevailing winds on
cooling system performance.
2. CAUTION! Caution must be used
when city water make up lines are
connected to the cooling system. City
water supply pressure may exceed the
20 PSI maximum limit of the radiator.
3. CAUTION! Piping to radiators
should be externally supported and
not hung on the radiator. Flexible
connections should be used when
piping to the radiator.
4. DANGER! For radiators that
include fan, motors, etc.: before initial
startup, inspect the fan to make sure
the blade tips do not hit the shroud, fan
ring or fan guard. Also, inspect all
moving parts (such as fans, motors,
shafts, sheaves and belts) for damage
and/or loose bolts.
5. DANGER! Failure to observe safety
precautions could cause personal injury
or equipment damage.
6. DANGER! Do not operate without
guards. Turn off power to install or
service. Use approved lockout/tagout
procedures.
7. DANGER! High voltage and
rotating parts may cause serious or fatal
injury.
8. WARNING! Over-tensioning belts
shortens belt and bearing life. (See
Section IV. B. for correct belt tensioning)
9. WARNING! Under-tensioning belts
can cause the following (See Section
IV. B. for correct belt tensioning):
− Premature belt wear
− Reduced radiator cooling
performance as a result of slower fan
speed
− Fan failure. Some types of fans may
have critical or resonant frequencies
that must be avoided.
10. DANGER! Do not make any
changes to any fan drive components
that may change or vary the original
design fan speed. All fans have a
maximum safe operating speed and
some fans may have minimum and/or
resonance speeds that must be
considered. Consult with Rocore
engineering before considering, changing
or varying a fan’s speed.
11. DANGER! Avoid extended exposure to
equipment with high noise levels.
12. CAUTION! Do not overfill the
radiator or surge tank. As the system
heats up, the coolant will expand and hot
coolant or steam will be forced out of the
overflow hose. (See Section III. F. for
correct filling instructions)
13. CAUTION! Check with engine
manufacturer to ensure that the coolant
used is compatible with their
requirements.

12
III. INSTALLATION
A. PLACEMENT AND MOUNTING
The radiator is designed for locations that allow adequate airflow to and from the
radiator. For engine mounted radiators, there should be no obstructions in the airstream
other than the engine. If ductwork is used on the radiator’s air discharge, its cross-
sectional area should be equal to or larger than the core area. The ductwork should be
straight or include large radius turns with no sharp corners. Consult Rocore for
recommendations regarding airflow restrictions caused by ducts, louvers, or other
obstructions.
Take precautions to allow a free flow of air to and from the radiator to prevent
recirculation of the heated discharge air from the radiator back into its intake system.
The unit should be no closer than one unit width away from any obstruction, wall or
another radiator. Keep a minimum clearance around the radiator for maintenance and
repair.
The installation should consider the potentially negative effects of prevailing winds on a
radiator’s performance. Do not face a vertical radiator’s discharge airstream into a
prevailing wind.
Remote radiators usually are not sized to accommodate engine room or any other air
rise, or external static restrictions to airflow, unless specified in the application design
data.
Standard remote radiators should be bolted to a level, solid foundation or structure.
Spring type isolators are not recommended for applications that require vibration
isolation between the radiator and the foundation or structure. Spring type isolators can
allow or induce vibration or movement to the radiator, which will void the warranty.
Instead, rubber-pad type vibration isolators are recommended.
Engine-mounted radiators must not be allowed to float freely from the engine. If
isolators are to be used, the radiator must be rigidly mounted to the engine, with the
engine/radiator combination mounted together on isolators.
CAUTION! Rocore standard radiators are designed for a maximum of 250 degrees
Fahrenheit and 20 psi(g) operation. Exceeding these limitations will void the warranty.
1. GENERAL
All Rocore radiator assembly drawings include mounting dimensions.
2. MODEL ‘N’TYPE RADIATORS (FAN ON ENGINE)
This type of radiator should be mounted to the engine skid with the mounting
holes provided at the bottom of each side member. The customer should provide
bracing from near the top of the radiator side member down to the engine skid
(See Fig. 2A).

13
3. MODEL ‘F’TYPE RADIATORS (FAN ON RADIATOR)
This type of radiator should be mounted to the engine skid with the mounting
holes provided at the bottom of each radiator side member and along the base
channels. The customer should provide bracing from near the top of the radiator
side member down to the engine skid (See Fig. 2B).
4. MODEL ‘V’TYPE RADIATORS
This type of radiator should be mounted with the mounting holes provided at the
bottom of each side member and along the base channels.
5. MODEL ‘H’TYPE RADIATORS
Horizontal radiators should be mounted with the holes provided at the bottom of
each leg.
B. MOUNTING SURGE TANKS ON REMOTE RADIATORS
On some remote radiators, the surge tank is shipped loose and must be installed by the
customer. See the radiator assembly drawing for the proper location and orientation of
the surge tank on the radiator.
See Figure 3 for additional details on connecting the surge tank to a horizontal remote
radiator.
To help prevent pump cavitation on horizontal radiators, it is recommended that the
surge tank be mounted on the radiator water outlet end (pump suction side), and that a
1/4 inch to 1/2 inch (*) vent line be installed from the radiator inlet piping or tank to
the surge tank, as shown schematically in Figures 8, 9 & 11.
The surge tank should be 1/4 to 1/3 filled when cold. The additional volume
accommodates the approximately five percent system expansion when hot and to
maintain some air space at all times in the top of the surge tank.
(*) Size of vent lines or filling lines is dependent on engine size and the
engine manufacturer’s recommendations.

C. PIPING
The following pages show piping schematics for various applications, one of which
should suit your needs.
All piping connections to the radiator should be externally supported; not hung on the
radiator. Flexible connections are required when connecting piping to a radiator. Piping
and connections should be designed to isolate the radiator from vibration and thermal
expansion loading. Piping should be of ample size and with as few bends or elbows as
possible. Use long sweep elbows or long bends.
CAUTION! When piping is higher than the radiator, the piping high points (both
supply and return) must also be vented to the surge tank!
WARNING! Improper connection of piping or improper filling may cause engine
damage.
1. ENGINE-MOUNTED RADIATORS
All engine-mounted radiators should be piped as shown in Figure 4. The radiator top
tank must be the highest point in the system and a 1/4 inch to 1/2 inch (*) vent line
from the engine thermostat housing to the radiator top tank may be required.
When the radiator has a deaeration baffle in the top tank, the plumbing is as illustrated
in Figure 5. A 3/4 inch to 1 inch (*) line from the engine water pump to the radiator
top tank pump suction port is required, and a 1/4 inch to 1/2 inch (*) vent line from the
engine thermostat housing to the radiator top tank is recommended. A fast fill port may
be provided on radiators with a deaeration baffle. This port is used to initially fill the
radiator. If a fast fill port is not available, fill through the radiator inlet(s). After initial run
up, recheck the system to be sure it is filled. Connection of the deaeration system
should be in accordance with the engine manufacturer’s recommendations.
2. VERTICAL REMOTE MOUNTED RADIATORS
Vertical type remote mounted radiators should be piped as shown in Figure 6. The
radiator top tank should be the highest point in the system. The customer should also
install a drain valve at the lowest point in the system.
When a separate surge tank is required with a vertical remote radiator, the system is
piped as in Figure 7. The surge tank should be the highest point in the system and a
3/4 inch to 1 inch (*) fill line is required from the bottom of the surge tank to the
radiator outlet pipe or pump suction line. Connecting the surge tank fill line to the
radiator top tank may cause pump cavitation, depending on the elevation of the radiator
with respect to the engine. If the engine is higher than the radiator or the engine
requires it, a 1/4 inch to 1/2 inch (*) vent line is required to the surge tank from the
thermostat housing or the highest point in the system. The customer should install a
drain valve at the lowest point in the system.
(*) Size of vent lines or filling lines is dependent on engine size and the
engine manufacturer’s recommendations.
