Commissioning, Startup, Operation, and Shutdown
a) Fill the bearing chamber through the main body of the Watchdog until it reaches the
optimum fluid level visible in the bullseye sight.
b) Fill the watchdog reservoir using a funnel.
c) Verify o-ring is on the Watchdog oiler spout.
d) Place your thumb over the reservoir spout. Invert and insert the spout into the internal
threaded boss on the main body.
e) Tighten reservoir. Do not over-tighten.
f)
Verify that proper oil level is maintained per the following diagram.
NOTICE:
Do not fill the oil reservoir of the bearing frame through the plug at the top.
2. Check that the oil level is correct. The correct oil level is centered in the bullseye sight
glass, when the pump is not in operation. During operation, bullseye sight gives a false oil
level reading. Shown is general schematic. Oil level is below outer race of bearing.

Lubricate the bearings with pure or purge-oil mist (optional)
NOTICE:
Do not expose an idle pump to freezing conditions. Drain all liquid that is inside the pump and
the cooling coils. Failure to do so can cause liquid to freeze and damage the pump.
Before lubricating with purge-oil mist, make sure that the bearing frame is properly lubricated.
See Lubricate the bearings with oil.
The oil requirements for ring-oil-lubricated bearings also apply to oil-mist-lubricated bearings.
NOTICE:
Oil mist is recommended for use on ball bearing arrangements only. See Convert to oil-mist
lubrication.
1. Prepare the oil-mist generator according to the manufacturer's instructions.
2. Connect the oil-mist supply lines to the oil-ring inspection plug connections.
Note that only one of the two connection ports in the radial bearing housing (134) is used
(immediately above the single row radial bearing). You must connect to both connections
on the thrust bearing housing, because there are two rows of bearings.
Oil-mist connections
A.
Radial and thrust
B.
Thrust only
C.
Radial and thrust drain
3. For pure-oil mist, connect the drain lines to the outlet connections.
This is not required for purge-oil mist.
