Installation

section.
General Instructions
Do not install any bulb type sprinkler
if the bulb is cracked or there is a loss
of liquid from the bulb. With the sprin-
kler held horizontally, a small air bubble
should be present. The diameter of the
air bubble is approximately 1,6 mm.
A 1/2 in. NPT sprinkler joint should be
obtained with a minimum to maximum
torque of 9,5 to 19,0 N
·
m. Higher levels
of torque may distort the sprinkler inlet
and cause leakage or impairment of the
sprinkler.
Do not attempt to make-up for insuf-
ficient adjustment in the escutcheon
plate by under- or over-tightening the
sprinkler. Re-adjust the position of the
sprinkler fitting to suit.

Care and
Maintenance
The Model EC-HS Sprinklers must be
maintained and serviced in accordance
with this section.
Before closing a fire protection system
main control valve for maintenance
work on the fire protection system that
it controls, permission to shut down the
affected fire protection system must be
obtained from the proper authorities
and all personnel who may be affected
by this action must be notified.
The owner must assure that the sprin-

objects; otherwise, non-operation in
the event of a fire or inadvertent oper-
ation may result.
Absence of an escutcheon, which is
used to cover a clearance hole, may
delay the time to sprinkler operation in
a fire situation.
Sprinklers that are found to be leaking
or exhibiting visible signs of corrosion
must be replaced.
