8. Start the source water flow and purge the water piping as
well as the evaporator in the unit.
9. Start the auxiliary equipment for the installation by turning on
the time clock, ambient thermostat and/or remote on/off switch.
10. Adjust the setpoint on the MicroTech II controller to the
desired hot water temperature.
11. Check resets of all equipment protection controls.
12. Switch the unit circuit breakers to “on.”
13. Start the system by pushing the system switch S1 to “on.”
WARNING
Most relays and terminals in the control center are powered
when S1 is closed and the control circuit disconnect is on.
Therefore, do not close S1 until ready for start-up or serious
equipment damage can occur.
14. Place pumpdown switch(es) PS1 and PS2 to the “auto
pumpdown” position for restart and normal operation.
15. After running the unit for a short time, check the oil level in
each compressor crankcase and for flashing in the refrigerant
sightglass (see Maintenance section).
WARNING
This unit contains POE lubricants that must be handled
carefully and the proper protective equipment (gloves, eye
protection, etc.) must be used when handling POE lubricant.
POE must not come into contact with any surface or material
that might be harmed by POE, including certain polymers
(e.g. PVC/CPVC and polycarbonate piping).
Daikin Applied recommends against the use of PVC and
CPVC piping for chilled water systems. In the event the pipe
is exposed to POE oil used in the refrigerant system, the pipe
can be chemically damaged and pipe failure can occur. Also,
do not use oil or refrigerant additives in the system.
General
The liquid line sightglass/moisture indicator on all circuits
must be checked to be sure the glass is full and clear and the
moisture indicator indicates a dry condition. If the indicator
shows that a wet condition exists or if bubbles show in the
glass, even with a full refrigerant charge, the filter-drier element
should be changed if acid test or oil analysis indicated acid
conditions.
Water supplies in some areas can tend to foul the TGZ
heat exchangers to the point where cleaning is necessary.
The fouled vessel will be indicated by an abnormally high
condensing pressure or low evaporating pressures and
can result in nuisance trip-outs. To clean the vessels, a
chemical descaling solution should be used according to the
manufacturer’s directions.
The condenser sensor should be cleaned anytime the
condenser is opened. This should typically be performed
at the annual inspection, however more frequent cleaning
may be required depending on the conditions of the jobsite.
Recommended maintenance includes checking the sensor tip
for buildup and cleaning the tip using a soft cloth. Stubborn
build up (e.g., lime) can be removed using a common vinegar
cleaning agent.
WARNING
Warranty is voided if wiring is not in accordance with
specifications. A blown fuse or tripped protector indicates a
short ground or overload. Before replacing fuse or restarting
compressor, the trouble must be found and corrected. It is
important to have a qualified control panel electrician service
this panel. Unqualified tampering with the controls can cause
serious damage to equipment and void the warranty.
Prior to attempting any service on the control center, study the
wiring diagram furnished with the unit so that you understand
the operation of the unit.
DANGER
The panel is always energized even if the system switch
is off. If it is necessary to de-energize the complete panel,
including crankcase heaters, pull the main unit disconnect.
Failure to do so may result in serious personal injury or
death.
If motor or compressor damage is suspected, do not restart
until qualified service personnel have checked the unit.
Electrical Terminals
DANGER
To avoid injury from electric shock hazard, turn off all power
before continuing with the following service.
All power electrical terminals should be checked for tightness
every six months, as they tend to loosen in service due to
normal heating and cooling of the wire.
