Section V Maintenance
To avoid electrical shock, disconnect the mains cord prior to removing
any access panels or covers.
Service Contracts
NESLAB offers on-site Service Contracts that are designed to provide
extended life and minimal down-time for your unit. For more information,
contact our Service Department (see Preface, After-sale Support).
Condenser
For proper operation, the unit needs to pull substantial amounts of air
through a condenser. A build up of dust or debris on the fins of the
condenser will lead to a loss of cooling capacity.
Periodic vacuuming of the condenser is necessary. To access the condenser
the front grille must be removed.
The unit must be turned off before the front panel is removed.
RTE-111 units have a one-piece grille assembly. Pull forward to remove.
RTE-211 and RTE-221 units have a two piece grille assembly. First remove
the left (blue-colored) section by simply pulling it forward. Pull forward on the
remaining (white-colored) section to remove it.
The frequency of cleaning depends on the operating environment. After initial
installation, we recommend a monthly visual inspection of the condenser.
After several months, the frequency of cleaning will be established.
