Econofrost 7000 Series Installation Guide

Before You Start

1. For maximum efficiency and cost savings, try to use as many 8-foot 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 the 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 the night covers where they will infringe upon merchandise and shelving. Try to avoid installing the night covers near sharp edges or in positions that will expose the fabric to undue wear and tear.

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


Installation Instructions

Step 1: Evaluate the case layout for the most symmetrical positioning of the units. Measure the distance from one end of the case to the other – install as many 8-foot units in parallel succession as possible.

Step 2: Lay the units out on the return air grill along the length of the case. This provides an accurate picture of the exact positioning of the units, ensuring a uniform installation.

Step 3: Using a pencil/scribe, mark the left hand side (LHS) of the case canopy where you will mount the first bracket.

Use 2 x #6 3/4″ self drilling/self tapping screws to secure this endcap bracket.
*You need an extended drill bit (Phillips #2) to fit into the hole & secure the screw.

Step 4: Hold the unit & use the level tool to verify that it is perfectly level then secure the right hand side (RHS) bracket.

Tip: You can use a deep vise grip or spring clamp to hold the unit in place while you secure the RHS endcap bracket.

Step 5: Insert the hole-cover tabs into both the LHS & RHS endcap brackets. Before installing the next unit, test the retraction of the night cover by pulling it down to the bumper and releasing it.

Standard factory-set retraction time is 3-5 seconds. If unit has lost tension, please refer to the re-tensioning instructions.

*If a hook-for-handle is required to secure the cassette’s handle to the bottom/bumper of the display case follow Step 6.1 otherwise proceed to Step 7.

Step 6.1: Installing a hook on the case bumper. To install the hook-for handle (optional), pull the cassette down by the handle in a straight and even manner. Mark the handle position in the middle of the case bumper. Using the drill, attach the hook to the case bumper and use your level to ensure it is even.

*When installing subsequent units, align all hooks at the same level.

Step 7: Repeat process with the remaining units ensuring flush and level mounts, again testing the tension of each unit prior to installing.

Tip: The magnet fasteners are easily removed with a bottle opener-like tool.

Econofrost 7000 Series Re-tensioning Guide

Econofrost night cover units come factory pre-tensioned. Occasionally during transport, the night cover may lose its original tension. Prior to installing the cassettes, the installer should confirm the tension is set. Standard retraction time is 3-5 seconds for complete retraction of the night cover.

Tools required: Phillips head screwdriver, impact drill with extended 1/16 drill bit, step ladder, vise grips


Re-tensioning Instructions

Removing a night cover that is currently installed

1. Remove the hole plugs from each end bracket (use a flat-head screwdriver or other thin blade).
2. Remove the night cover using the impact drill with extended 1/16 drill bit to undo the screws securing the unit to the case.

Option 1 – Setting Spring Tension Using Vise Grips

Step 1: With a Phillips screwdriver, remove the LHS endcap bracket screws (keep a solid hold on the endcap). If there is any tension left in the spring you will feel it  and the spring will want to unwind. Release remaining tension in the spring.

Step 2: Using the vise grips, pinch the metal end-pin and rotate clock-wise 18-25 complete turns. Hold onto the night cover unit so it does not unwind at the same time.

Step 3: After you have completed the rotations on the unit, carefully reverse the rotation 1/4 to 1/2 turn to lock the tension in place.

Important: To lock tension, “notch” and arrow (see picture right) must point up.

Re-insert the endcap bracket and re-fasten endcap bracket screws. We recommend you fasten them only part way first so you may test the tension of the unit.

If the tension is adequate, fasten them fully. If the tension is not adequate, repeat steps 2 and 3 (first part) until the desired tension is achieved.

Step 4: Once the tension has been adequately reset, re-install the unit onto the display case. Using the impact drill with extended drill bit (Phillips #2), secure the two self-drilling mounting screws back in place.

Unit is now fully tensioned with retraction time of 3-5 seconds.

Option 2 – Setting Spring Tension Using the Endcap Bracket

Step 1: With a Phillips screwdriver, remove the LHS endcap bracket screws (keep a solid hold on the endcap). If there is any tension left in the spring you will feel it and the spring will want to unwind. Release remaining tension in the spring.

Pull the roll out of the right hand endcap bracket slightly so that the night cover roll extends past the aluminum cassette housing.

Step 2: Using the LHS endcap bracket, rotate the spring clock-wise 18-25 complete turns. Hold onto the night cover unit so it does not unwind at the same time.

Caution: Do not over tension and do not apply side pressure (spring may break).

Step 3: It is important to lock the tension in place after winding the spindle. After you have completed the rotations on the unit, carefully reverse the rotation 1/4 to 1/2 turn to lock the tension in place.

Important: To lock tension, “notch” & arrow (see picture right) must point up.

Hold the endcap bracket in place and replace the RHS back into position and carefully maneuver the LHS endcap bracket into place on the cover.

With a firm grasp on the unit and endcap bracket, secure the two endcap screws. We recommend you fasten them only part way first so you may test the tension of the unit. If tension is adequate, fasten them fully. If tension is not adequate, repeat steps 2 and 3 (first part) until the desired tension is achieved.

Step 4: Once the tension has been adequately reset, re-install the unit onto the display case. Using the impact drill with extended drill bit (Phillips #2), secure the two self-drilling mounting screws back in place.

Unit is now fully tensioned with retraction time of 3-5 seconds
