Routine Maintenance Instructions
All Bobrick Dryers require cleaning every 6 months to ensure that they function
effectively. Please note that failing to clean the dryer may result in malfunction and
can void the warranty.
If the dryer is installed in an area prone to dust and dirt this cleaning procedure
should be carried out more frequently.
Check the length of motor brushes, where applicable, when performing the cleaning
procedure.
Cleaning Instructions:
a) The Exterior of Cover
Should be cleaned with a damp cloth, DO NOT use aggressive cleaners or solvents
as they may permanently damage the surface.
Bobrick dryers are drip proof (IP21 or better, see rating label). DO NOT spray with
liquids to an extent that they could enter the unit.
b) The Interior
Having turned off all power to the dryer, remove the cover.
Using a small brush or vacuum, carefully clean out the build up of dust and lint.
Check the length of the motor brushes. If less than ½" replace. Check that motor
brushes are installed correctly and that brushes are worn evenly.
Replace the cover.
Turn the power back on.

Installation Of Touch Controller
To Remove Existing Timer
1. Disconnect the power supply and remove the cover.
2. Remove the timer from the base plate by unscrewing the two screws securing the timer bracket to the
base. On recessed dryers the timer bracket is secured to a metal angle bracket, this bracket with its
screws must be removed and retained for use on the replacement timer.
3. Disconnect the pink or yellow, red, and black timer wires from the terminal block and the white wire
push on connector from the triac (115V only). Place the timer aside for return to the Service
Department.
To Install New Timer
1. Mount the timer assembly to the base plate . In the case of recessed dryers, it is first necessary to
attach the metal angle bracket removed from the faulty timer to the new timer.
2. Route the timer wiring under the element tube and attach the white wire push on connector to the
small spade terminal on the triac (115V only), older 208 –240V units may have a base plate mounted
triac, this is no longer required and can be removed.
3. Connect the remaining three timer wires to the terminal block, black wire to terminal 1, red wire to
terminal 2, pink wire to terminal 3.
4. Secure wiring with cable ties provided.
5. Replace dryer cover. Switch on electrical supply and test
operation.
