Make sure provisions are made for the following plumbing connections:
1. Use only approved sealants on the EZFill refill system. Class1 recom-
mends using:
❑ Plastic Pipe – Permatex #80724 (or equal) thread sealing compound
❑ Metal Pipe – Loctite PST (or equal) thread sealing compound
2. Install the tank FULL
level sensor near the
top of the appropriate
foam tank. (See Fig-
ure 3-3: ‘Sample, Tank
FULL Sensor Mount-
ing.’)
Note: Exact sensor posi-
tion may vary, depended
on tank design.
3. Drill and tap a 1/2”-14
NPT hole and install
the sensor. Apply
pipe sealant to avoid
leaks.
Tighten the sensor having the “arrow” on the base of the hex pointing
down. After installation, verify switch operation using a powered test
light. (See Figure 3-3: “Sample, Tank FULL Sensor Mounting.”)
Note: If a dual tank system is
used, a second tank FULL
level sensor must be installed
in tank “B” as well.
4. Install the quick discon-
nect suction hose
adapter and hardware by
drilling a 1-3/8" (35mm)
clearance
hole. The
adapter should be
located in a convenient
location on the operator’s
panel. (See Figure 3-4:
“Quick Disconnect Suc-
tion Hose Adapter Instal-
lation.”)
5. Connect a suction hose between the quick disconnect suction hose adapter
and the pump.
