other recessed escutcheon will void all approvals and negate
all warranties. When installing Model F1S5-56 and F1S5 LO
Recessed Pendent use the Model GFR2 Sprinkler Wrench.
Any other type of wrench may damage these sprinklers.
Note:
A leak tight sprinkler joint can be obtained with a torque
of 8-18 ft-lb (10.8 - 24.4 N-m). Do not tighten sprinklers over
maximum recommended torque. It may cause leakage or
impairment of the sprinklers.
Glass bulb sprinklers have orange covers to protect
the bulb during the installation process. REMOVE THIS
PROTECTION ONLY AFTER THE SYSTEM HAS BEEN
HYDROSTATICALLY TESTED AND, WHEN APPLICABLE,
THE ESCUTCHEONS HAVE BEEN INSTALLED. RASCO
wrenches are designed to install sprinklers when covers are
in place.
