4.0 INSTALLATION
4.1 STRUCTURAL REQUIREMENTS
4.2 CONNECTION TO WATER SUPPLY
4.2.1 INSTALLATION ON HUM OR IVUM (SIDE A OPTION H)
1. Install the supplied O-ring onto the barb that protrudes from the bottom flange
of the Booster. Apply silicone grease over the O-ring.
2. Align the Booster with the HUM or IVUM as shown.
3. For the IVUM only, the IVUM Flange Adapter must be oriented such that the
non-threaded counter-bored holes are aligned with screw locations 3 and 5,
and the threaded holes are aligned with the other six screw locations.
Orientation of the Booster to the IVUM is flexible; however it is critical to
choose an orientation such that the LDH Inlet Port C3 on the Booster will not
interfere with the crank handle on the IVUM.
4. Apply Loctite 242 (blue) thread-locking adhesive to (8) supplied ½-13 x 1.5”
screws, then hand tighten into the locations shown until the screw heads are
bottomed out. Screw numbers 3 and 5 are inserted up thru the HUM or IVUM,
then into the Booster. The other six screws are inserted through the Side A
Inlet flange of the Booster.
5. Tighten the (8) screws to 40 to 45 ft-lb (54-61 N-m) torque in the alternating
sequence shown on Figure 4.2.1. Tighten at graduated intervals of 30%, then
60%, and finally 100% of the specified torque.
4.2.2 BOOSTER OSC INSTALLATION ON HUM OR IVUM (SIDE A
OPTION H)
1. Depress the red latch and remove the safety Guard from Oscillating Booster.
2. Use 5/16” hex key to remove four 3/8”-16 x 1” long socket head cap screws
from the cover plate surrounding the oscillating gearbox. Remove gearbox from Oscillating Booster and set it aside.
3. Loosen the belts by using an adjustable wrench to tighten the belt tensioner. Remove the top belt from the pulleys first, then
remove the bottom belt. Set parts aside.
4. Use 5/16” hex key to remove four 3/8”-16 x 1.5” long socket head cap screws from the pulley housing. Lift pulley housing away
from Booster body. It may be necessary to pry gently to overcome the adhesion of residual Loctite in the screw holes.
5. Follow steps 1 through 5 in
.
6. Install pulley housing using the four 3/8”-16 x 1.5” long screws that were originally installed. Apply Loctite 242 blue to screws, then
tighten snug against pulley housing. Maximum torque allowed is 200 in-lb (17 ft-lb, 23 N-m).
7. The two belts are identical. Install one belt over silver-colored input shaft and lower-right pulley. Install other belt between upper
left pulley and lower-right pulley. Back the belt tensioner out until it bottoms out. Verify that belts are seated properly and are taut
between pulleys.
8. Install gearbox over pulleys by pivoting gearbox until the gearbox shaft slides into the socket of the top pulley. Then, pivot the
cover plate until it seats flush against the pulley housing.
9. Apply blue Loctite to four 3/8-16 x 1” long screws and install snug against cover plate. Maximum torque allowed is 200 in-lb (17 ft-
lb, 23 N-m).
CAUTION
Mismatched or damaged waterway connections may cause equipment to leak or uncouple under
pressure. Failure could result in injury. Equipment must be mated to matched connections.
CAUTION
Dissimilar metals coupled together can cause galvanic corrosion that can result in the inability to
uncouple the connection, or complete loss of engagement over time. Failure could cause injury. Per
NFPA 1962, if dissimilar metals are left coupled together, an anti-corrosive lubricant should be
applied to the connection and the coupling should be disconnected and inspected at least
quarterly.
WARNING
Reaction forces generated by master stream flows are capable of causing injury and property
damage if not properly supported. Monitors should be securely installed by qualified individuals.
• Mounting objects must be capable of withstanding maximum nozzle reaction force listed in
SPECIFICATIONS.
• The monitor must be securely mounted to rigid support members.
• Do not use flanges or pipe made from plastic for monitor mounting.
• Torque all fasteners to specified values.
