9000 Series Retrofit Cassette Installation Guide

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.

Installation Instructions – 5000AK Series Cassette

Step 1Â Â 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.

Setting Spring Tension Using Allen Key Tool

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

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

Step 3Â Â 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 4Â Â 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 5Â Â 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 6Â Â 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.
