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
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.
Important
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 -
MAC
1.Installation and maintenance are to be performed only by qualified refrigeration personnel. These technicians must have EPA certification (USA), are familiar with local codes and regulations, and are 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.
