General Maintenance
General Maintenance
Normal maintenance on any HydroBank MS unit
includes but may not be limited to the following.
Air filter changes
Air filters must be replaced a minimum of two times
per year. A good standard to follow is at the beginning
of the cooling season and the beginning of the heating
season. In certain environments, more frequent filter
changes may be required.
For new installations, it is recommended that the air fil-
ters be checked every 60 days and changed as required
until a regular interval can be established.
The filter is changed by sliding it out of the filter rack as
shown in Figure 27. On units equipped with the four-sid-
ed filter rack option, the filter door pivots open for easy
filter removal and replacement.

Dirty Filter Switch Option
The dirty filter switch option is designed to inform main-
tenance personnel when it is time to change filters. The
switch senses the pressure drop across the filter.
On units equipped with Mammoth EPiC controls, a
warning will be indicated when filters need changing. If
the filters are not changed, the EPiC control will go into
an alarm status and the unit will shut down. The alarm
must be cleared before the switch will reset.
Condensate drain
The condensate drain and drain pan should be checked
on an annual basis to verify positive drainage and
cleaned or flushed as necessary.
Electrical
Check the tightness of all electrical terminals twice each
year. Retighten as needed.
WARNING!
Loose electrical terminals can
lead to erratic unit operation and arcing
which may cause fires.
WARNING!
Electric shock and moving
equipment hazard. Can cause severe injury
or death. Lock and tag out all electric power
before carrying out these procedures. More
than one disconnect may be required to de-
energize the unit.
Data recording
Recording current draw of blower motors at regular
intervals is recommended to verify their condition.
Recording differences in water temperature and air tem-
perature at regular intervals can help identify any perfor-
mance degradation. Annual comparison of the data will
aid in determining the overall condition and operation of
the unit.
Nuisance trips and/or lockouts
Occasional trips and/or lockouts are generally caused
by water or airflow restrictions. When a trip or lockout
occurs, check the water flow rate, incoming water tem-
perature, airflow rates and incoming air temperature.
Take corrective action necessary to enable unit operation.
See the troubleshooting guide on page 21 for more tips.
