SERVICE
— LOCK OUT / TAG OUT —
To avoid serious injury or death from electrical
shock, always disconnect the electrical power
at the main disconnect when servicing or
replacing any electrical component. This
includes, but is not limited to, such items as
doors, lights, fans, heaters, and thermostats.
11 . Close air gaps under fan plenum . Warmer
air moving into refrigerated air reduces
effective cooling . If the plenum does not
rest against the case bottom without gaps,
apply foam tape to the bottom of the fan
plenum to reduce improper air movement .
Use silicone sealant to close other gaps .
12 . Reinstall display pans . Bring merchandiser
to operating temperature before restocking .

and number of fans will
