O. REPLACEMENT OF WATER COOLED
CONDENSER
1. Remove front/top and side/rear panels on
models SP125-255, SPN405-605 and the front
and right side panel on model SPN1205.
2. Remove the condenser temperature sensor
probes from condenser.
3. Remove bolts which secure the condenser
to the unit base.
4. Remove the corbin clamps and disconnect
the plastic hoses from the water cooled
condenser.
5. Recover the refrigerant from the system
and transfer it in a container so to reclaim or
recycle it.
6. Unsolder the refrigerant lines from the
condenser and remove it from the unit.
NOTE. It is imperative to install a replacement
drier whenever the sealed refrigeration
system is open.
Do not replace the drier until all other repairs
or replacements have been completed.
7. To install the replacement condenser follow
the above steps in reverse.
NOTE. Thoroughly evacuate the system to
remove moisture and non condensables after
condenser replacement.
P. REPLACEMENT OF WATER
REGULATING VALVE (WATER COOLED
MODELS)
1. Remove the front/top and side/rear panels
on models SP125-255, SPN405-605 and left
side panel on model SPN 1205.
2 Close the shut-off valve on the water supply
line and disconnect it at the rear of the flaker.
3. Remove corbin clamp and disconnect the
water hose from the outlet of water regulating
valve.
4. Unloose the nut securing the water
regulating valve to the unit frame.
5. Recover the refrigerant from the system
and transfer it in a container so to reclaim or
recycle it.
6. Trace the water regulating valve capillary
tube and unsolder its end from the refrigerant line
then remove it from the unit.
NOTE. It is imperative to install a replacement
drier whenever the sealed refrigeration
system is open. Do not replace the drier until
all other repairs or replacements have been
completed.
7. To install the replacement water regulating
valve follow the above steps in reverse.
NOTE. Thoroughly evacuate the system to
remove moisture and non condensables after
water regulating valve replacement.
NOTE. The water flow that passes through
the valve can be adjusted by means of the
valve setting stem in order to have a
condensing pressure of 8.5 bar on SP12 5
and of 17 bar on SP255 SPN 405-605-1205
Q. REPLACEMENT OF COMPRESSOR
1. Remove front/top and side/rear panels on
models SP125-255, SPN405-605 and the
front panel on model SPN 1205.
2. Remove the cover and disconnect the
electrical leads from the compressor junction
box.
3. Recover the refrigerant from the system
and transfer it in a container so to reclaim or
recycle it.
4. Unsolder and disconnect both the suction
line and the discharge line from the compressor.
5. Remove the four compressor mounting bolts
and the compressor from the unit base.
6. Unsolder suction and process header from
compressor and retain it to be used on new
compressor.
NOTE. Always install a replacement drier
whenever the sealed refrigeration system is
open.
Do not replace the drier until all other repairs
or replacements have been completed.
7. To install the replacement compressor
follow the above steps in reverse.
NOTE. Thoroughly evacuate the system to
remove moisture and non condensables after
compressor replacement.
