CARE AND CLEANING
Adherence to regular and proper cleaning procedures will preserve the appearance of your
device. Scratched or damaged surfaces caused by misuse, mishandling, improper storage, or
improper cleaning are not covered under the limited warranty.
A LIST OF "DON'TS"
Don't
store the device without the protective plastic shipment bag.
Don't
store or place the device face down on any surface.
Don't
use abrasive or highly alkaline cleaners.
FOREIGN SUBSTANCE REMOVAL
The use of the following products should help remove foreign substances from your Masterclock
device:
Butyl Cellosolve
(Removal of paints, marking pens, lipstick, etc.)
The use of adhesive tape or lint removal tools work well for lifting off old weathered paints.
Kerosene, naphtha, or petroleum spirits
is generally effective to remove labels, stickers, etc.
When the solvent will not penetrate sticker material, apply heat (hair dryer) to soften the
adhesive and promote removal.
Gasoline should never be used.
JOB SITE PRECAUTIONS
We recommend that devices be removed from the wall and stored face up in their protective
shipment bags during painting and construction.
New construction and renovations frequently require that the job site be cleaned of any excess
mortar, paint, sealant, primers or other construction compounds. Only recommended cleaners
should be used to clean the polycarbonate lens. Contact with harsh solvents such as methyl ethyl
ketone (MEK) or muriatic acid can result in surface degradation and possible crazing of the
polycarbonate.
