Vacuum pump
A vacuum pump will allow you to fully benefit from the capabilities of your Surveyor sensor.
Your pump kit (either #19228 or #19233) includes the following parts:
If your pump was not factory installed or bought separately, you will need to install the
pressure valve bulkhead on your housing. You have two optional emplacements to install your
vacuum pump system:
Rear ½’’ bulkhead
port, compatible with pump kit #19228
Front 16mm bulkhead port, compatible with pump kit #19233
While it is possible to mount your pump in the front 16mm port, it is recommended to use the
dedicated ½’’ port.
Using the front 16mm port will prevent you from using an external
monitor bulkhead.
To install your valve:
STEP 1:
Remove the existing plug by unscrewing the hexagonal nut inside.
STEP 2:
Lubricate the valve bulkhead O-ring using provided Aquatica O-ring lubricant (see
the O-rings section at page
28 for more information).
STEP 3:
Carefully insert the valve bulkhead into the selected port, slightly rotating the
valve while pushing will facilitate the insertion.
STEP 4:
Tighten the retaining nut using a 5/8’’ wrench.
