Connecting Refrigerant Lines
Connection of refrigeration lines is to be undertaken by qualified persons only.
Refrigeration pipes are located under the pan decks and can be run from case to case through designated access holes in
the end frames and/or out via the bungs at the rear and base of the case. See Fig (1): service layout for location of the
refrigerant up-stand, and Fig (15) for the location of access holes.
Up to four cases can share one refrigeration up-stand, however, to ensure best performance, it is recommended that no
more than three cases share an up-stand.
The evaporator coils have been charged with dry nitrogen in the factory.
Fig (15) Refrigeration access holes
CAUTION
Do not run refrigeration lines from another compressor through
a case. Since pressure in the first system responds to the
coldest location, refrigeration lines from the first system running
through a second system may be chilled to the point that its
pressure control will respond to the pressure from the second
system. This is called cross controlling and should be avoided.
To connect refrigeration lines:
1. Ensure the evaporator coils are fully charged by checking the dry nitrogen holding charge against the pressure
written on the tag attached to the coil.
2. Drill holes through bungs and foam and run pipes as per store requirements.
3. Braze the pipes to the coil using dry nitrogen to prevent any foreign matter being left in the lines. Keep pressure
below 1700kPa (250 Psig).

4. Insulate all external pipe work to Standard practice and Customer specifications.
5. Seal off all external access holes with polyurethane foam and then bituminous paint to prevent leakage and
condensation.
6. Connect to condensing unit or compressor.
7. Pressure test all welded and fastened connections to ensure they are free of leaks.
8. Dehydrate the refrigeration system using the triple evacuation method. Use a vacuum pump to 1000 microns for
the first two evacuations and 500 microns on the third, or to the customer’s specific requirements. Break
evacuations 1 and 2 with dry nitrogen, allowing the pressure to rise above atmospheric pressure each time.
9. Charge with refrigerant after final (3rd) evacuation.
Installing a Waste Drain
NOTES
Drains must be connected as per
stipulated local council requirements.
All joins must be solvent welded.
Each case must be connected to its own waste drain See Figure 1: service layout for of the drain up-stand. It is
recommended that 40mm DWV (PVC) piping be used.
To install a waste drain:
1. Fit an elbow and pipe to the existing pipe work.
2. Check that the drain is as per Fig (16a).

Daily Checks
•If an alarm system is not part of the refrigeration installation, the temperature of each case should be checked on
a daily basis via the thermometer that may be located in the left hand side of the ceiling panel, or via another reliable
method.
The case temperature should be in the range of 0C - 2C for both case types.
Up to three separate readings may have to be taken to ensure the case temperature isn’t being taken during a
defrost cycle (which would give a higher than desired reading).
If it is consistently outside this range, contact Hussmann or your service contractor.
•Visually check the case for damage or spills and take appropriate remedial action.
CAUTION
If any damaged electrical components are
identified during inspection isolate case
power and contact service contractor.
•Visually inspect drain strainer and drain for any debris which could result in the drains becoming blocked with the
possibility of spilling on the floor creating a slip hazard
Cleaning
A thorough cleaning and service of the case should be carried out by qualified refrigeration and electrical engineers on a
six monthly basis. Please contact your service contractor.
Cases should also be cleaned by store staff on at least a weekly basis; some cases may, however, require more frequent
cleaning.
Important Notes
•Do not use hot water on cold glass surfaces as the glass may shatter and cause serious injury.
•Do not use abrasive, solvent, ammonia or oil-based cleaners.
•Do not use steam or a high-pressure system to clean the case.
•When flushing the waste drain, do not use high-pressure water hoses and be careful not to introduce water faster
than the waste outlet/drain can drain it.
Cleaning Procedure
1. Turn off the cleaning switch. Isolate power and remove stock.
