Chilled Water, Hot Water and Steam Coils
Startup
Visually check the coils and system piping for proper
installation and any signs of leakage. Repair as needed.
Check motorized valves and linkages for the following
points of operation.
•
The motor should be free to run through its complete
stroke.
• The linkage should work freely without binding.
• The valve must close off tightly at the bottom of its
stroke.
Controls Startup
For controls startup procedures, see the EPIC ® Sequence
of Controls documentation that is included in the packet
of information that is zip-tied to the inside of the main
control panel.
Final System Check
• Verify that controller read out values are equal to
actual gauge or temperature readings, as applicable.
• Install all refrigeration fitting caps, etc., that were
removed during the startup procedure.
• Check the refrigeration system for leaks.
• Clean up all debris.
General Maintenance
Normal maintenance on any V-Cube Slim™ 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 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.
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 equip-
ment 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.
Electrical terminals are located within the main unit con-
trol panel. Tighten all terminals per the torque value listed
on the connector. Where no torque value is given, use
the tightening torques provided in this manual. See “Elec-
trical Terminal Tightening Torques” on page 16.
On all units with electric heat, check the condition of
contactors and wiring at the beginning of each heating
season.
Data recording
Recording current draw of blower motors at regular inter-
vals is recommended to verify their condition. Recording
differences in water temperature and air temperature at
regular intervals can help identify any performance deg-
radation. Annual comparison of the data will aid in deter-
mining 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 temper-
ature, airflow rates and incoming air temperature. Take
corrective action necessary to enable unit operation.
