Below is an outline of the general installation and retension instructions for the 5000 series retrofit cassette and the 5000 series non-cassette OEM version. We also have included installation/retension instructions for the 5000 series in Spanish too.

To assist you with your night cover installation we are also providing a set of instructions which you can download.

If you ever have any questions regarding the installation of the ECONOFROST brand of night covers, please give us a call (toll free in North America) at 1-800-519-1222 or at (250) 743-1222.

Before You Start

1. For maximum efficiency and cost savings try to use as many 8ft units as possible. This will allow you to cover the greatest linear length using the least number of units.

2. When installing the night covers, be careful of any wiring inside the display case canopy and within the installation area.

3. When installing ECONOFROST night covers, be sure to install the blinds in such a manner that the refrigerated cold air curtain remains behind the night cover (inside the case) as it was intended.

4. Be aware of any misting systems (produce cases) and be sure not to block access to the refrigeration controls. Try to avoid installing ECONOFROST night covers where they will infringe upon merchandise and shelving. Try to avoid installing the night covers near sharp edges of in positions that will expose the fabric to undue wear and tear.

5. Before officially starting, be sure to remove all signage, boards and bag racks as required.

Step 1   Choose the location for mounting - typically on the front of the display case canopy. Hold the ECONOFROST cassette up to the location where it will be mounted. Ensure the cover is level before marking the location. Mark the intended position on the mounting surface by scribing the case at each end of the cassette.

Step 2    Slide the mounting tabs (A) out of the end caps (B). Line up the mounting tabs with marks made on the display case canopy. Use the tabs as a template and mark where the holes are to be drilled

Step 3   Drill the holes to accept the sheet metal screws. Affix mounting tabs to display case using sheet metal screws. Slide the cassette unit onto the mounting tabs and secure by placing a set screw in the holes provided on the nylon end caps.

Step 4    Determine place at the bottom of the case to mount hook for the handle - usually below bumper or moulding. Ensure the hook is centered with the handle. Use hook as a template to marke the holes to be drilled. Drill the holes and mount the hook using sheet metal screws. Pull the ECONOFROST cover down and slip the handle onto the hook.

Retension Instructions - 9000 Series Cassette

Removal of an ECONOFROST unit that is currently installed
1. Remove the set screws on both mounting brackets.
2. Slide off the cassette unit and spindle roll assembly from the plastic mounting end-cap "ear" tabs (mounting Endcap tabs remain affixed to the case).

Setting Spring Tension Using Allen Key Tool

Step 1   Re-tensioning mechansim access is located at the left side of the unit. It can be identified by the Philips screw head.

Step 2   Remove the locking screw to reveal the hexagonal pin-end of the spring mechanism.

Step 3   Insert a 5mm hexagonal key for re-tensioning. Push the key in until it unlocks the setting, and spring tension is loosened. Turn the hexagonal key (keep it pushed in) 18-25 times clockwise, or until the tension feels sufficient. Caution: Do Not over tension.

Step 4   Once the expected tension is reached, bring lock pin to its original set position (out) using the hexagonal key. This holds the spring tension.

Step 5   Replace the locking screw gently. Ensure the screw does not push in the lock pin in order to avoid loosening the tension. With the end-caps re-attached, hold up the cassette unit and pull down on the fabric and release to test tension and retraction. If tension is not acceptable repeast steps 4-5 with either more turns (more tension is added) or less turns (loosens tension).

Step 6   Re-attach the cassette unit to the case, sliding the end caps over the mounting tab "ears". Important: Ensure the small set screws at the bottom of the end caps are in the place to lock the unit to the mounting tabs.
