INSTALLATION
The Mizar S215 must be installed in accordance with the
following instructions:
NOTES
Do not install any bulb type sprinkler if the bulb is
cracked or there is a loss of liquid from the bulb. With
the sprinkler held horizontally, a small air bubble with
an approximate diameter of 1/16 inch should be pre-
sent.
A leak tight 1/2 inch NPT sprinkler joint should be ob-
tained with a torque of 7 to 14 ft.lbs. (9,5 to 19,0 Nm).
A maximum of 21 ft.lbs. (28,5 Nm) of torque is to be
used to install sprinklers. Higher levels of torque may
distort the sprinkler inlet with consequent leakage or
impairment of the sprinkler.
Do not attempt to compensate for insufficient adjust-
ment in an Escutcheon Plate by under- or over-tight-
ening the Sprinkler. Readjust the position of the sprin-
kler fitting to suit.
1. The sprinkler must only be installed with the centerline
of the waterway horizontal and perpendicular to the
backwall surface.
2. After installing the #2084 mounting plate (or other ac-
ceptable escutcheon, as applicable) over the sprinkler
pipe threads and with pipe thread sealant applied to the
pipe threads, hand tighten the sprinkler into the sprinkler
fitting.
3. Wrench tighten the sprinkler using only the W-Type 7
Sprinkler Wrench (Ref. Figure 4). The wrench recess of
the W-Type 7 is to be applied to the sprinkler wrench
flats (Ref. Figure 1). The word “TOP” on the Deflector is
to face towards the ceiling.
CARE AND MAINTENANCE
The Mizar S215 must be maintained and serviced in ac-
cordance with the following instructions:
NOTES
Wet pipe sprinkler systems must be maintained at a
minimum temperature of 40°F/4°C to prevent freezing
and bursting of the pipe and/or sprinklers.
Automatic sprinklers are not to be tested with a heat
source. Operation of the heat responsive element
(bulb) can result.
Absence of an Escutcheon Plate may delay the time
to sprinkler operation in a fire situation.
Before closing a fire protection system main control
valve for maintenance work on the fire protection sys-
tem which it controls, permission to shut down the af-
fected fire protection system must be obtained from
the proper authorities and all personnel who may be
affected by this action must be notified.
Do NOT enclose sprinklers within drapes, curtains, or
valances.
Do NOT hang anything from the sprinklers.
Do NOT cleanse the sprinklers with soap and water,
detergents, ammonia, cleaning fluids, or other chemi-
cals. Remove dust, lint, cobwebs, cocoons, insects,
and larvae by gently brushing with a feather duster or
gently vacuuming with a soft bristle (i.e., dusting)
brush attachment.
Exercise suitable safety precautions in the use and
storage of highly flammable materials. The rapid rate
of fire development and spread of which can be
caused by such materials can reduce the ability of
the sprinkler system to aid in the control of a fire in
which they are involved.
The minimum vertical clearance between the tops of
free standing partitions, room dividers, cabinets, stor-
age racks, stock piles, etc., and the sprinkler deflec-
tor is NOT to be less than the clearance given below.
Sprinklers which are found to be leaking or exhibiting vis-
ible signs of corrosion must be replaced.
Automatic sprinklers must never be shipped or stored
where its temperature will exceed 100°F/38°C and they
must never be painted, plated, coated, or otherwise al-
tered after leaving the factory. Modified sprinklers must
be replaced. Sprinklers that have been exposed to corro-
sive products of combustion, but have not operated,
should be completely cleaned by wiping the sprinkler with
a cloth or by brushing it with a soft bristle brush.
