Human Touch HT-7120 Quick Start Manual

To ensure that Human Touch products are repaired in a manner that is fully consistent with the practices used during the manufacturing process, Human Touch requires that all
®
product repairs are performed using only factory-new parts and in accordance with these product repair instructions.
Tools Required: Needle-nosed pliers, vice grip, Phillips-head screwdriver, 5/32-inch (4 mm) Allen key, small hammer, nail clipper or other instrument suitable for cutting zip ties, new zip ties.
NOTE: This procedure can be completed by one person, although having a second person is helpful when installing the new backrest. SAVE ALL SCREWS FOR USE DURING REASSEMBLY.
REMOVING THE BACKREST
DISCONNECT THE AIR PUMP
1. Power off the chair and unplug it.
2. Using a 5/32-inch (4 mm) Allen key, remove the four screws from the backrest cover.
3. Tip the backrest cover backward and lay it gently on the floor behind the chair. (Fig.1).
4. Locate the two air pump tube connections to the backrest (Fig.2).
5. Mark each tube and its corresponding fitting, to use as reference when reconnecting the new air pump. The tubes
must be connected to the correct fitting.
6. Using a nail clipper (or other instrument suitable for cutting zip ties), cut the zip ties that secure the two tubes to
the backrest, then remove the tubes from the backrest.
DISCONNECT THE BACKREST
1. Power the chair back on, use the remote control to completely recline the backrest, then power the chair
back off and unplug it.
2. Disconnect the three connectors at the base of the backrest cover, then remove the backrest cover from
the chair (Fig.1).
3. Place a sturdy object, such as a heavy box or ottoman, under the reclined backrest for support (Fig.3).
NOTE: This is necessary as, once the recline actuator is disengaged, the backrest swings freely.
