ASSEMBLY:
1. Inspect and clean the tank, ring threads and O-ring groove. Replace
damaged parts as necessary.
2. Install the filter module with the unplugged port over the tank outlet port.
Push down firmly to seal.
3. Ensure that the air bleed assembly on top of the module is clean and
properly mounted.
4. Lubricate O-ring only with the silicone grease provided or equivalent (Dow
Corning grade 111), as other lubricants may cause the ring to swell. DO
NOT lubricate Posi-Lok™ ring or threads on lower tank shell as this may
collect grit and make removal difficult.
5. Install the O-ring in the upper tank shell. Be sure that the O-ring is clean
and not twisted.
6. Push the upper tank shell into the lower tank shell to compress the O-ring.
7. Place the Posi-Lok™ ring squarely over the tank shell threads and rotate
COUNTERCLOCKWISE until the ring falls into the slots; then rotate
CLOCKWISE until securely latched (See Figure 4).
Safety Latch (See Figure 5)
NOTICE: The safety latch locks the Posi-Lok™ ring in position. DO NOT operate
the filter if the safety latch is damaged or will not hold the Posi-Lok™ ring in the
locked position. If the latch is damaged, replace it as follows:
1. Press down on the small catch behind the safety latch and press or tap the
latch out of the “Tee” slot in the tank (See Figure 5).
2. Snap the new latch into position.
START-UP
Be sure pump is OFF before starting procedure.
Do not operate this filter at more than 50 PSI (345 kPa) under any
circumstances!
1. Lock the Posi-Lok™ ring in place by rotating ring CLOCKWISE until one of
the ring tabs is captured by the safety latch. See Figure 4.
2. Fill trap on pump with water.
3. Open air release valve on top of filter; open isolation valves.
4. Start pump to purge air from system. When a steady stream of water comes
from air release valve, close the valve.
NOTICE: Leaking around the Posi-Lok™ ring may indicate that the ring is
not fully locked. In this case, make sure the O-Ring and seat are clean and
undamaged, and then again follow the instructions in this sheet under
“Disassembly” and “Assembly”.
