HT-7450 Troubleshooting Guide 5
Massage Comfort Control
This section assumes that the air bags are not inflating/deflating as you
adjust the Massage Comfort Number.
1. While adjusting the Massage Comfort Number, listen carefully for
the sound of the air pump.
2. If you can hear the air pump running softly:
a. Check the air tubing connection to the back of the left-hand
armrest to make sure the connection is secure.
b. Remove the tubing from the armrest, then check to see if the
white plastic end of the fitting has broken off and is stuck inside
the armrest. If this is the case, replace the tubing/fitting.
3. If you can hear the air pump running loudly:
a. Using two hands, pull outward on the left-hand side panel to
separate it from the chair.
b. Check to see if the air hose tubing has detached from the fitting.
c. If the tubing is detached from the fitting, reattach it, then secure
it by sliding the white zip tie firmly over the fitting connection.
4. If you cannot hear the motor running, the air pump is not working
properly. Replace the chair base.
DEALER NOTE: You may wish to replace the air pump instead of the
chair base.
