A Few Words About Safety

Safety Information

Read and understand the entire manual before
operating or maintaining Stoelting equipment.

This manual provides the operator with information
for the safe operation and maintenance of Stoelting
equipment. As with any machine, there are hazards
associated with their operation. For this reason safety

The purpose of safety symbols is to attract your at­tention to possible dangers. The safety symbols, and
their explanations, deserve your careful attention
and understanding. The safety warnings do not by
themselves eliminate any danger. The instructions
or warnings they give are not substitutes for proper
accident prevention measures.

If you need to replace a part, use genuine Stoelting
parts with the correct part number or an equivalent
part. We strongly recommend that you do not use
replacement parts of inferior quality.

2.2 RECEIVING THE CUSTARD MACHINE

A. Upon arrival, check the entire machine for any

damage that may have occurred during transit.
With the method of packaging used, the machine
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 machine has 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.

B. Remove the top of the crate using a hammer or

pry bar.

C. Remove the eight lag bolts from the machine

using a 1/2” ratchet. Remove the front and rear
crate walls.

D. Remove the four lag bolts located inside the left

and right crate walls using 1/2” ratchet. Remove
the left and right crate walls.

E. Remove the plastic wrapping on the machine.

Remove the lower front and back panel on the
machine.

F . Remove the four lag bolts located inside machine

on the frame with a 9/16” ratchet. Remove the
two lag bolts that hold the skid together with a
9/16” socket.

G. If the machine has the shipping casters or if it is

water-cooled, the casters will be in a box located
in the hopper pan. A set of casters includes two
casters with locks and two casters without locks.
Screw the casters into the threaded holes and
tighten them using a pair of channel locks. After
installing the casters, knock out bottom 4” x 4” of
the machine skid.

NOTE

If the machine does not come with casters, install
the stainless steel legs. The legs are located in the
hopper pan on top of the machine. After installing
the legs, use a pallet jack to move machine into
place.

H. Put front and back panels on the machine.

2.3 MACHINE INSTALLATION

The following instructions are intended for a qualifi ed
electrician/refrigeration specialist. Do not attempt these
procedures unless you are qualifi ed.

CAUTION

Installation MUST be completed by a qualifi ed
electrician/refrigeration specialist

Incorrect installation may cause personal injury,
severe damage to the machine and will void fac­tory warranty.

A. RUNNING LINE SETS

NOTE

If the machine is water-cooled, proceed to “B. Run­ning Electrical Connections”.

Line sets are not supplied with the machine.
The lines sets can be installed prior to receiving the

custard machine.

1 An air-cooled machine requires a remote

condensing unit and line set for each freezing
cylinder. The line sets must be 3/8” for the liquid
line and 5/8” for the suction line. When running
the line sets, each 10’ of vertical rise, install a
p-trap in the suction line. For every horizontal
line set run, pitch the suction line towards the
compressor to assist with oil returning back to
the compressor.

2 After the line set is installed, perform a thorough

leak test. Malfunctions of the equipment due
to leaks in the line set are not covered by the
Stoelting/Ross warranty.
