Section 2
Installation
INSULATING CONNECTIONS
1. Make sure all exposed carbonated water and
syrup lines are well insulated on towers to conduit,
conduit junctions, refrigeration unit to conduits, and
drivethrough junction.
2. To insulate the above, use the leftover conduit sections
and tape.
3. Cut the conduit sections to fit snugly over the exposed
lines and fittings. A little extra time spent doing a
thorough job initially will eliminate a call back in
several days to make corrections.
NOTE: Do not inject foam material directly on the
connections where the tubing connects to the barb fittings
or directly on poly tubing.
Aerosol Foam
Chase
4. The can of foam is to be used to fill the openings
between the conduit insulation and the inside
diameter of the floor chases. The purpose is to provide
an air tight seal at the floor level to prevent foreign
matter from entering the chases. Please read the foam
manufacturer’s instructions carefully. We recommend
using the adapter with the right angle extension.
5. Insert the adapter into the openings approximately 1"
to 2" (2.5 to 5.1 cm) while depressing the adapter.
6. Move the extension around throughout the area
where the foam is to be placed. Do not over fill, allow
room for expansion. If the chase opening is too deep,
insert a section of the leftover conduit insulation in the
opening prior to using the foam insulation.
Aeroquip Connection
1. Lubricate male half diaphragm and synthetic rubber
seal with refrigerant oil.
2. Thread male coupling to its proper female half by hand
to ensure proper mating of threads.
3. Use proper wrenches (on coupling body hex and its
union nut) and tighten union nut until coupling bodies
“bottom”.
NOTE: You must use a wrench on the body to keep the body
from turning while tightening the nut with the second
wrench. If the body turns excessively, the piercing seal will
be damaged.
4. Use proper wrenches to tighten an additional 1/4
turn (90°). This final 1/4 turn is necessary to ensure the
formation of a leak proof joint. Alternately, use a torque
wrench to tighten the 1/2" coupling to 40 ft-lbs and
3/8" fitting to 11 ft-lbs.
5. Leak check all your connections. If you detect any leaks,
repair and recheck.
Condenser and Pre-charged Lines Installation
Before proceeding with installation, verify that all
requirements for roof mounted remote condenser units
(if applicable) have been satisfied. If unit has a remote
condenser, refer to the instructions on installing the remote
condenser supplied with the condensing unit and refer to
the section on installation of remote refrigeration line sets.
,
Caution
If you are installing a remote unit, there is a refrigeration
king valve located behind the compressor. This valve
must be back-seated prior to starting the compressor.
Failure to do so will short cycle and may damage the
compressor.
REMOTE CONDENSER REQUIREMENTS
APPROVED CONDENSERS
Multiplex Condenser - TS0895-271
MAC Multi-Pass Condensers
1. Installation and maintenance are to be performed only
by qualified refrigeration personnel. These technicians
must have EPA certification (USA), must be familiar with
local codes and regulations, and must be experienced
with this type of remote refrigeration equipment.
2. As a condition of the warranty, the check, test and
start-up procedure must be performed by qualified
personnel. Because of possible shipping damage, check
both the condensing unit and refrigeration unit(s) for
refrigerant leaks.
3. If the refrigeration unit is located on a roll out platform,
you must coil up to one round between the back
of the stand and the wall. This allows pull out of the
refrigeration unit for servicing.
4. If the refrigeration unit is located in a stationary
location, you must remove excess refrigeration tubing
as described below.
