Owner`s manual

Safety glasses and protective
clothing should be worn while
servicing the HS115. Refer
installation and service to
qualified personnel only.
Splash danger! Because the
flex tube contains chemical
product and is flexible, extra
caution should be taken while
changing the flex tube to
ensure that the chemical does
not splash in the eyes or in the
hands or clothing of the service
personnel.
Always wear protective eye
wear, gloves and clothing
when changing the flex tube.

Priming the Pump
1. Ensure that you are in Run Mode.
2. Press the Prime Button to operate the pump.
3. Hold prime button until the Heatsavr™ liquid has filled the lines all the
way to the injection point.
4. If any air bubbles are entering the lines at a fitting, tighten the fitting.
Maintenance
Periodic Maintenance:
Pump & Flex Tube Replacement Schedule
Since every installation is different (operating frequency varies) an exact
tube replacement schedule cannot be specified. With use, the tube slowly
evolves from round to oval, and the amount of Heatsavr
TM
pumped
decreases. By regularly checking the amount of Heatsavr
TM
pumped, you can
determine general tube life. We recommend that you closely monitor the
time it takes the original tube to reach the end of its flex life, and then
establish a replacement schedule. Replacing tubes at regularly scheduled
intervals ensures more accurate product use and reduces service calls. In
general, short feed lines of a large diameter will improve pump tube life.
Replacing Pump Cartridges
To Remove
1. Turn off power to the unit to ensure that the pump does not run
during maintenance.
2. Remove the cartridge from the motor housing by twisting the
snap pins at top and bottom 90° to the left or right.
3. Remove the supply and feed lines from the old pump flex tubing
and connect them to the new pump flex tubing.
To Install
1. Align and engage the pump drive spline with the motor gear by
rotating the roller assembly.
2. Turn the snap pins so that the arrow is pointed up; then push in
until you hear a distinct click.
Replacing Pump Flex Tubing
1. Remove the cartridge as described above.
2. Loosen but do not remove the small screw at the bottom of the
rear cover and lift the cover from the cartridge.
3. Pull the roller assembly out of the pump cartridge to release the
pump flex tubing.
4. Pull the tube inserts out of the pump cartridge.
5. Remove the flex tube and replace it with a new flex tube.
6. When inserting a new flex tube, coat the inside of the cartridge
with a liberal amount of the provided lubricant.
7. Press the two tube inserts into the cartridge so that the zip tie
wrap "buckles" face toward the center of the pump. Remember,
the tube must not be twisted during the assembly.
8. Replace the roller assembly and then the rear cover; re-tighten
the screw.
