CONDENSING UNITS
NOTE
The remote condensing units may be sent prior to
delivery of the freezer.
The freezer requires one remote condensing unit
per cylinder.
Remote condenser models 285092 and 285093
are shipped from the factory charged with 20 lbs
of R404a refrigerant.
Remote condenser models CU-0010 and CU-0020
are shipped from the factory without a refrigerant
charge.
1 Upon arrival, check the entire remote condenser
units for any damage that may have occurred
during transit. With the method of packaging used,
the remote condensers should arrive in excellent
condition. The carrier is responsible for all damage
in transit, whether visible or concealed. Do not
pay the freight bill until the remote condenser
units have been checked for damage. Have the
carrier note any visible damage on the freight
bill. If concealed damage or a shortage is found
later, advise the carrier within 10 days and request
inspection. The customer must place a claim for
damages and/or shortages in shipment with the
carrier. Stoelting cannot make any claims against
the carrier.
2 Remove cardboard covering off the condensing
units.
3 Place the condensing units in their predetermined
location, either on the roof or on the ground. A
crane or forklift will be needed if the units will be
placed on a roof. The condensing units weigh
approximately 200 lbs. each.
4 Using ratchet with a 1/2” socket, remove the two
lag bolts that secure the condensing unit to the
pallet.
5 Place the condensing units on 4” x 4” treated
wood or similar material so that the units are not
sitting directly on the ground or the roof. Secure
the condensing units to the 4” x 4” using lag
bolts. Adhere to all local, state, and federal codes
governing this type of installation. Some areas
have specifi c “hurricane-proof” requirements
for roof installations. Allow at least 3 feet of
clearance on the air intake and discharge sides
of the condensers. Do not set the condensers
so that one is blowing air directly into the other
condensing unit. The ideal set up is to have all
the condensing units set in a row (Fig. 2-1).
NOTE
On CU-0010 and CU-0020 remote condenser
models, use an Allen wrench to open the shut off
valves and release some of the nitrogen charge in
the condensing unit. The shut off valves are located
on the outside of the condensing unit. If no nitrogen
is present then the unit needs to be leak checked
prior to connecting the refrigeration lines.
7 Braze the suction line and liquid line from the
line sets to the condensing unit. When brazing,
wrap the shut off valve with a cold wet rag. If the
valve is not wrapped, damage to the valve may
result. When installing the suction line, angle it
towards the condensing unit so that oil can fl ow
back towards the compressor.
8 Use good piping practices. Keep pipes as clean as
possible. Do not let any debris or copper shavings
get inside system otherwise the refrigeration
valves may not work properly.
E. SETTING IN PLACE AND MAKING MACHINE
CONNECTIONS
1 Roll the machine into the desired location. Leave
adequate space around the machine for the
removal of service panels. Remove the left, right,
back and lower front service panels.
NOTE
After the refrigeration lines are connected, air-
cooled machines cannot be moved.
2 Use a pallet jack or fl oor jack to lift the front of the
machine, remove the two shipping casters with
a pair of channel locks, and install the stainless
steel legs. Make sure the legs are adjusted all the
way in, and screw two of the legs into the frame.
Secure them tightly using channel locks. Repeat
with the back of the machine.
NOTE
If the machine is water-cooled, casters are standard
with machine.
3 Accurate leveling is necessary to ensure
proper operation. Place a bubble level on top
of the machine at each corner to check for level
condition. If adjustment is necessary, level the
machine by turning the bottom part of each leg
or caster in or out.
To fi nish installing a water-cooled machine,
proceed to “F. Running product and setting
pressures for the custard machine”.
