Normal maintenance on any V-Cube Slim™ unit in-
cludes buy may not be limited to:
 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 heating 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 filters be checked every 60 days and
changed as required until a regular interval can be
established. An air filter needs to be replaced if no
light can be seen through it when it is held up to a
light.
 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.
General Maintenance
 Data recording. Recording current draw of blower
motors at regular intervals is recommended to ver-
ify their condition. Recording differences in water
temperature and air temperature at regular inter-
vals can help identify any performance degrada-
tion. Annual comparison of the data will aid in de-
termining 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 tempera-
ture, airflow rates and incoming air temperature.
Take corrective action necessary to enable unit
operation.

Heating Cooling Possible Cause Solution
Insufficient Capacity X X Dirty Filter Replace or clean
Not cooling or heating
properly

Reduced or no air flow in
heating
Check for dirty air filter and clean or replace, Check fan motor operation
and airflow restriction. Too high of external static? Check static vs. blower
table
X X Leaky ductwork
Check supply and return air temperatures at the unit and at distant duct
registers: If significantly different, duct leaks are present
