3. PRODUCT DESCRIPTION

Viking Micromatic® Special Response

Sprinklers are small thermosensitive

glass bulb sprinklers available in various

finishes, temperature ratings, and orifice

sizes to meet design requirements.

During fire conditions, the heat-sensitive

liquid in the glass bulb expands, causing

the bulb to shatter, releasing the pip cap

and sealing spring assembly. Water

flowing through the sprinkler orifice

strikes the sprinkler deflector forming a

uniform spray pattern to extinguish or

control the fire.

5. INSTALLATION

WARNING:Viking sprinklers are manufactured and tested to meet the rigid requirements of approving agencies. The

sprinklers are designed to be installed in

accordance with recognized installation

standards. Deviation from the standards

or any alteration to the sprinkler after it

leaves the factory including, but not limited to: painting, plating, coating, or

modification, may render the sprinkler

inoperative and would automatically nullify the approval and any guarantee

made by The Viking Corporation.

A. Viking sprinklers are to be installed

in accordance with the latest

edition of Viking technical data,

the latest standards of NFPA, FM

Global, LPCB, Assemblee

Pleniere, VdS, or other similar organizations, and also with the provisions of governmental codes,

ordinances, and standards whenever applicable. The use of Special

Response sprinklers may be limited

due to occupancy and hazard. Refer

to the Authority Having Jurisdiction

prior to installation.

B. Sprinklers must be handled with care.

They must be stored in a cool, dry

place in their original shipping container. Never install sprinklers that

have been dropped, damaged, or exposed to temperatures exceeding

(5 mm glass bulb is an alternate).the maximum ambient temperature

allowed (refer to Table 1). Never install any glass-bulb sprinkler if the

bulb is cracked or if there is a loss of

liquid from the bulb. Any sprinkler

with a loss of liquid from the glass

bulb should be destroyed immediately.

C. Sprinklers must be protected from

mechanical damage. Sprinklers subject to mechanical damage must be

protected with an approved sprinkler

guard.

D. Use only sprinklers listed as corrosion resistant when subject to corrosive environments. When installing

corrosion-resistant sprinklers, take

care not to damage the corrosion-resistant coating. Use only the special

wrench designed for installing coated

and recessed Viking sprinklers (any

other wrenchmay damage the unit).

E. Use care when locating sprinklers

near fixtures that can generate heat.

Do not install sprinklers where they

could be exposed to temperatures

exceeding the maximum recommended ambient temperature for the

temperature rating used.

F. Wet-pipe systems must be provided

with adequate heat. Sprinklers supplied from dry systems in areas subject to freezing must be listed dry

sprinklers, or upright or horizontal

sidewall sprinklers installed so that

water is not trapped. For dry systems, pendent sprinklers and sidewall sprinklers installed on return

bends are permitted, where the

sprinklers, return bend, and branch

line piping are in an area maintained

at or above 40 °F (4 °C). When installing Special Response Sprinklers on dry systems, refer to the installation standards and the Authority

Having Jurisdiction.

G. Before installation, be sure to have

the appropriate sprinkler model and

style, with the correct orifice size,

temperature rating, and response

characteristics. The sprinklers must

be installed after the piping is in place

to prevent mechanical damage.

Keep sprinklers with protective caps

or shields contained within the caps

or shields during installation and testing, and any time the sprinkler is

shipped or handled.

2. Apply a small amount of pipe-joint

compound or tape to the external

threads of the sprinkler only, taking care not to allow a buildup of

compound in the sprinkler inlet.

NOTE: Sprinklers with protective

caps or bulb shields must be contained within the caps or shields

before applying pipe-joint compound or tape.

3. Install the sprinkler onto the piping

using the special sprinkler wrench

only, taking care not to overtighten or damage the sprinkler

operating parts. DO NOT use the

deflector to start or thread the

sprinkler into a fitting.

H. After installation, the entire sprinkler

system must be tested. The test must

be conducted to comply with the installation standards.

Make sure the sprinkler has been

properly tightened. If a thread leak

occurs, normally the sprinkler must

be removed, new pipe-joint compound or tape applied, and then reinstalled. This is due to the fact that

when the joint seal is damaged, the

sealing compound or tape is washed

out of the joint.

Air testing the sprinkler piping prior to

testing with water may be considered

in areas where leakage during testing

must be prevented. Refer to the installation standards and the Authority

Having Jurisdiction.

I.Remove plastic protective sprinkler

caps or shields AFTER the ceiling

finish work is completed where

the sprinkler is installed and there

no longer is a potential for mechanical damage to sprinkler operating elements. To remove the

bulb shields, simply pull the ends of

the shields apart where they are

snapped together. To remove caps

from frame style sprinklers, turn the

caps slightly and pull them off the

sprinklers. SPRINKLER CAPS OR

BULB SHIELDS MUST BE REMOVED FROM SPRINKLERS BEFORE PLACING THE SYSTEM IN

SERVICE!Retain a protective cap in

the spare sprinkler cabinet.

J. If it is necessary to remove the entire

sprinkler unit, the system must be

taken out of service. See section 7.

MAINTENANCE and follow all warnings and instructions.

7. MAINTENANCE

NOTICE: The owner is responsible for

maintaining the fire protection system

and devices in proper operating condition. For minimum maintenance and inspection requirements, refer to the

NFPA standard that describes care and

maintenance of sprinkler systems. In

addition, the Authority Having Jurisdiction may have additional maintenance,

testing, and inspection requirements

that must be followed.

A. Sprinklers must be inspected on a

regular basis for corrosion, mechanical damage, obstructions, paint, etc.

The frequency of the inspections

may vary due to corrosive atmospheres, water supplies, and activity

around the device.

B. Sprinklers that have been painted,

caulked, or mechanically damaged

must be replaced immediately.

Sprinklers showingsigns of corrosion

shall be tested and/or replaced immediately as required. Installation

standards require sprinklers to be

tested, and if necessary, replaced after a specified term of service. Refer

to the installation standards (e.g.,

NFPA 25) and the Authority Having

Jurisdiction for the specified period of

time after which testing and/or replacement is required. Sprinklers

that have operated cannot be reassembled or re-used, but must be replaced. When replacing sprinklers,

use only new sprinklers.

C. The sprinkler discharge pattern is critical for proper fire protection. Nothing

should be hung from, attached to, or

otherwise obstruct the discharge pattern. All obstructions must be immediately removed or, if necessary, additional sprinklers installed.

D. When replacing existing sprinklers,

the system must be removed from

service. Refer to the appropriate sysSprinkler 125 c

Figure 1tem description and/or valve instructions. Prior to removing the system

from service, notify all Authorities

Having Jurisdiction. Consideration

should be given to employment of a

fire patrol in the affected area.

1. Remove the system from service,

drain all water, and relieve all

pressure on the piping.

2. Using the special sprinkler wrench,

remove the old sprinkler and install the new unit. Care must be

taken to ensure that the replacement sprinkler is the proper model

and style, with the correct orifice

size, temperature rating, and response characteristics. A fully

stocked spare sprinkler cabinet

should be provided for this purpose. Follow instructions in section 6. INSTALLATION.

3. Place the system back in service

and secure all valves. Check for

and repair all leaks. Sprinkler systems that have been subjected to

a fire must be returned to service

as soon as possible. The entire

system must be inspected for

damage and repaired or replaced

as necessary. Sprinklers that

have been exposed to corrosive

products of combustion or high

ambient temperatures, but have

not operated, should be replaced.

Refer to the Authority Having Jurisdiction for minimum replacement requirements.
