Systems C250 Unit you would like to configure.
2.
Navigate to the "Diag" button in the bottom right corner of
your screen and select "IP Configuration"
Unit IP Address – This IP address is the designation for the unit
itself, Nyle recommends running the system on factory settings
(ex. 192.168.1.("Unit Number" AKA 1))
Unit IP Subnet – This number is used to determine the size of
the network the unit is connecting to. (ex. 255.255.255.0)
Master IP Address – This is the address of the Nyle Systems
Master Panel (ex. 192.168.1.50)
Unit Number – Only used for custom network configurations,
this configures your Nyle unit to connect to a Master Panel under
a desired number.
MAINTENANCE AND SERVICE
ROUTINE MAINTENANCE
Warning: When possible, disconnect all power to the unit and
follow the prescribed lock - out/tag - out procedure to
prevent accidental electrocution. Should the unit have to be
serviced with live electricity, only trained and qualified
technicians should carry out the service. Failure to follow all
of the safety warnings may result in serious injury or death.
The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken to ensure
26
that (1) no one is in front of or around the outlet
of the temperature pressure relief valve discharge line,
and (2) the water manually discharged will not cause any
bodily injury or property damage because the water may be
extremely hot. If after manually operating the valve, it fails to
completely reset and continues to release water, immediately close
the cold water inlet to the heat pump, follow the draining
instructions in the storage tank manual, and replace the
temperature-pressure relief valve with a properly rated/sized
new one.
If you do not understand these instructions or have any questions
regarding the temperature-pressure relief valve call the toll
free number listed on the back cover of this manual for technical
assistance.
CLEANING INTERNAL INSULATION
Inspect the internal insulation on a yearly basis for any microbial
growth. The insulation never has to be cleaned unless microbial
growth is detected. If microbial growth is detected, follow the
removal steps below:
1.
Disconnect all power to the unit and follow the prescribed
lock-out/tag-out procedure.
2.
Wear the prescribed personal protective equipment
prescribed from the cleaning product instructions.
3.
Remove as much dirt and organic material from the insu-
lation using a vacuum device with a HEPA filter (99.97%
efficient at 0.3 micron particles). Be careful not to tear the
insulation during the cleaning procedure.
4.
Apply the microbial cleaning agent as prescribed by the
application and usage instructions.
5.
Allow the unit to dry thoroughly.
6.
If necessary, apply an anti-microbial agent on the insulation
per the instructions provided on the product label.
Discard collected microbial contaminants as required by local
or state codes.
CHECKING REFRIGERANT CHARGE
Servicing of the refrigeration circuit must only be performed
by agencies or individuals possessing Type II or Universal
certification as defined in Section 608 of the Clean Air Act.
See Qualifications on page 3.
This HPWH unit is factory charged with 134a refrigerant. See
the rating label on the HPWH unit and Table 9 for refrigerant
charge by weight. It should not be necessary to add or
remove refrigerant during installation or start up. Refrigerant
lost during frequent refrigerant pressure testing can cause
low refrigerant conditions. Air and water flow should always
be checked first to eliminate other potential problems before
checking the refrigerant charge.
