Installation
DH80 Recessed, FP Escutcheon
To install the DH80 with the FP Escutcheon as a recessed
sprinkler cut a 2 58
²diameter hole in the wall as shown in
Figure1. Remove temporarily the plastic protective cap, then
use the GFR1 wrench to tighten the sprinkler until secured in
the sprinkler fitting. NOTE: The GFR1 wrench has a notch in
it to accommodate the deflector top. This wrench can only
be inserted one way. Care must be taken not to damage the
deflector during tightening. Apply a Teflon* based sealant
to the sprinkler threads before installing in the fitting. When
inserting or removing the wrench from the sprinkler cup,
care must be taken to prevent damage to the sprinkler.
Wrench only on the square boss. DO NOT WRENCH ON
ANY OTHER PART OF THE SPRINKLER. It is
recommended that the sprinkler be protected during
plastering and painting operations by reinstalling the
protective cap P/N 6802710003. Installation is completed
by removing the protective cap and inserting the push-on
escutcheon. Turn clockwise to adjust the escutcheon
against the wall.
DH80 Recessed, F2 Escutcheon
To install the DH80 with the F2 Escutcheon as a recessed
sprinkler cut a 2 ¼” diameter hole in the wall as shown in
Figure 2. Thread the DH80 into the collar hand tight. Apply a
Teflon* based sealant to the sprinkler threads and install in
the fitting. Wrench only on the square boss. NOTE: The
GFR1 wrench has a notch in it to accommodate the deflector
top. This wrench can only be inserted one way. When
inserting or removing the wrench from the sprinkler cup care
must be taken to prevent damage to the sprinkler. DO NOT
WRENCH ON ANY OTHER PART OF THE SPRINKLER. It is
recommended that the sprinkler be protected during
plastering and painting operations by using the protective
cap P/N 6999991009. These must be ordered separately.
Installation is completed by removing the protective cap and
inserting the F2 Escutcheon over the collar.
DH80 with SWC Cover Plate Concealed
To install the sprinkler, cut a 2 58
²diameter hole into the wall
as shown in Figure1. A Teflon* based thread sealant should
be applied to the sprinkler threads only. Remove the
protective cap (P/N 6802710003) and then position the
GFR1 wrench into the sprinkler/cup assembly until the
wrench engages the flats of the square boss. Then tighten
the sprinkler into the pipe fitting. When inserting or removing
the wrench from the sprinkler/cup assembly, care should be
taken to prevent damage to the sprinkler. DO NOT
WRENCH ON ANY OTHER PART OF THE SPRINKLER. The
protective caps should be reinstalled for protection during
plastering and painting. Remove caps only when covers are
being installed. The cover assembly is then pushed onto the
cup. Cover assemblies provide ½²(13mm) of adjustment.
Final adjustment is made by turning the cover clockwise until
the skirt flange makes full contact with the wall surface. Cover
removal requires turning in the counter- clockwise direction.
Concealed cover/cup assemblies are listed only for use
with specific sprinklers. The use of any other concealed
cover/cup assembly with the Model DH80 Horizontal Sidewall
Maintenance
Model DH80 should be inspected quarterly and the
sprinkler maintained in accordance with NFPA 25. Do not
clean sprinklers with soap and water, ammonia or any other
cleaning fluids. Remove dust by using a soft brush or gentle
vacuuming. Remove any sprinkler/cover assembly, which has
been painted (other than factory applied) or damaged in any
way. A stock of spare sprinklers should be maintained to allow
quick replacement of damaged or operated sprinklers. Prior to
installation, sprinklers should be maintained in their original
cartons and packaging until used to minimize the potential for
damage to sprinklers that would cause improper operation or
non-operation.

Sprinkler or the use of the concealed cover assembly on any
sprinkler with which it is not specifically listed will void all
guarantees, warranties, listings and approvals.
Note: DH80 and DH80 Recessed Sprinklers have orange
bulb protectors to minimize bulb damage during shipping,
handling, and installation. REMOVE THIS PROTECTION AT
THE TIME THE SPRINKLER SYSTEM IS PLACED IN SERVICE
FOR FIRE PROTECTION. Removal of the protectors before
this time may leave the bulb vulnerable to damage. RASCO
wrenches are designed to install sprinklers when covers are in
place. REMOVE PROTECTORS BY UNDOING THE CLASP
BY HAND. DO NOT USE TOOLS TO REMOVE THE
PROTECTORS.
