HIBLOW HP-100 & HP-120 REPAIR INSTRUCTIONS
Below are instructions on how to install this repair kit in a Hiblow air
pump. Please be sure to disconnect power from the unit before completing
TOOLS NEEDED TO COMPLETE INSTALLATION:
- 7mm or 1/4in Wrench, Socket, or Nut Driver
- Phillips Screwdriver
- Flathead Screwdriver
- Needlenose Pliers (Optional)
- Time to complete: 15-30 minutes
STEP 1: REMOVE THE AIR PUMP UPPER HOUSING
Hiblow Repair Step 1
Remove all the bolts from the four corners. NOTE: DO NOT DISCARD BOLTS,
THEY WILL BE REUSED. This is done easier using a 7mm or 1/4in socket
instead of a phillips screwdriver. Using a phillips screwdriver could
cause you to strip out the bolts. If upper pump housing is difficult to
remove due to the heavily stuck internal seal, pry it open by inserting
the tip of a flat-head screwdriver into the clearance between the
exhaust nozzle and upper housing.
Pull off the white sound absorber from around the internal pumping unit
and disconnect the L-TUBES on each end from the diaphragm head.
STEP 3: REMOVE THE DIAPHRAGM HEADS
Hiblow Repair Step 2
Using a phillips screwdriver. Remove the four screws that hold the
chamber block and the casing block on both side (4 screws on each side).
NOTE: DO NOT DISCARD SCREWS, THEY WILL BE REUSED.
STEP 4: REMOVE THE DIAPHRAGMS
Hiblow Repair Step 3
Using a 7mm (1/4in) wrench or nut driver remove the U-lock nuts that
hold the diaphragm to the magnetic rod block. Remove one of the
diaphragms from the actuating rod and pull out the other diaphragm with
the magnetic rod. Finally separate the diaphragm mounting block and rod.
STEP 5: INSTALL THE NEW DIAPHRAGMS
Hiblow Repair Step 4
Install the new diaphragm on the actuating rod before inserting the rod
back into the pump. Use new U-lock and washer that come with the kit to
prevent loosening and causing failure of the pump.
Insert the actuating rod in accordance with the gap of the frame. Secure
the diaphragm on the other side and tighten the U-lock nut with the box
driver. Make sure the gapes between the actuating rod and the
electromagnet are even.
STEP 5: INSTALL THE NEW DIAPHRAGM HEADS
Hiblow Repair Step 5
Install the heads on both sides with the 4 screws that were removed
originally. Reconnect the L-Tubes to the diaphragm head on each side.
STEP 6: INSTALL THE NEW SAFETY SCREW
Hiblow Repair Step 6
Draw a new safety screw through the hole in the SP switch and the holes
in the L shaped lever and spring contact. Fasten the screw with the nut
supplied and tighten with a flathead screwdriver. The screw is designed
so that the nut will turn freely when it is properly fastened. Stop
tightening when this happens.
A trick to getting the nut on the safety screw is to use a pair of
needlenose pliers to hole the nut in place while you turn the screw into it.
STEP 7: INSTALL THE SOUND ABSORBER AND UPPER HOUSING
Hiblow Repair Step 7
Replace the sound absorber removed in STEP 2 and place the upper housing
back on the body. Secure the upper housing with the bolts that were
removed in STEP 1.
STEP 8: ALL DONE!
Hook your air pump back up to your system!
