Section VI Maintenance and Service
For personal safety and equipment reliability, the following procedures
should only be performed by a qualified technician. Contact our
Service Department for assistance (see Preface, After-sale Support).

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).

Cleaning

Periodically inspect the reservoir. If cleaning is necessary, flush the reservoir
with a cleaning fluid compatible with the circulating system and the cooling
fluid.

Algae

To restrict the growth of algae in the reservoir, it is recommended that the
reservoir cover be kept in place and that all circulation lines be opaque.
This will eliminate the entrance of light which is required for the growth of
most common algae.
NESLAB recommends the use of Chloramine-T, one gram per gallon.

Pump Strainer

A wire mesh screen (under hex nut) is located in the pump suction line. If
debris is drawn into the system, the strainer will prevent the material from
being sucked into the pump and damaging the pump vanes.
After initial installation, the strainer may become clogged with debris and
scale. Therefore, the strainer must be cleaned after the first week of installa-
tion. After this first cleaning, a monthly visual inspection is recommended.
After several months, the cleaning frequency will be established.
PD-1 Pump: a wire mesh screen is located under the large acorn nut on the
head of the pump.
