Resin Loading And Assembly - North Star PA101 Manual

1. Move the resin tank into installation location (see
page 8). Set it on a flat, level surface. If a twin installa-
tion, keep tanks separated for ease of service.
2. Remove the shipping cap, top distributor and o---
rings. On all models, place the bottom distributor into
the resin tank. Check the distributor length as shown
in Figure 1 and adjust if needed. Center the distributor
in the tank.
3. With a pail or hose, fill the tank with 1 to 2 feet of
water. The water acts as a cushion to protect the bot-
tom distributor while filling the tank with gravel and
resin.
4. Plug the end of the distributor tube with a clean
rag, to keep gravel and resin out.
5. Using a larger neck funnel, add the specified (see
pages 2 and 4) amount of gravel. Be sure the dis-
tributor remains centered.
Note: When coarse, medium and fine gravels are spe-
cified, add in that order.
6. Add the specified amount of resin, using water
sparingly to speed flow through the funnel.
7. Flush the tank opening with water to clean resin
beads from the top of the tank. Then, remove the rag
from the distributor tube.
8. Finish filling the tank with water, up to the top of the
tank.
Important: Be sure to fill with water. This will elimi-
nate air space and prevent excessive air---head pres-
sure when the water conditioner is pressurized.
9. Install the o---ring seals and top distributor exactly
as shown in Figure 2. If the o---rings need lubrication,
use a high quality silicone grease.

Note: Resin tank height can vary somewhat
within manufacturing tolerance. So the bot-
tom distributor riser pipe has proper clear-
ance with inside valve porting, check for
the correct length as shown above. Cut the
riser if needed to adjust the length. Be sure to
remove burrs and sharp edges.
