Skew Adjustment - Aquamatic HYDRAMATIC Operational Manual

SKEW ADJUSTMENT - COVER ALIGNMENT
* A two to three inch variation on opening side to side is considered an acceptable tolerance. You may find this
even more so on vanishing edges or freeform pools that have a lot of deck drag.
Step 1
Prior to adjustment make sure that the cover is fully closed
(i.e. fabric covers pool water) before attempting any skew
adjustment. Remove pit housing lid.
Step 2
Loosen (do not remove) the two wing nuts (or 9/16 Hex Head
Bolts) by two complete revolutions on drive unit. Insert a
screwdriver into pre-cut slots (see diagram below) adjust roller
tube.
Step 3
Depending on which way the skew needs to be adjusted will
depend on which way you move the slots located on the
drive unit.
If for example, you need to move the leading edge bar towards the pit housing as in fig. A. you will need to insert a
screwdriver and adjust the slots 1/2" - (10mm) at a time.
Step 4
Close and reopen the cover and repeat above procedure if more adjustment is required.
For surface mounted cover systems:- remove the end lid panel above drive unit, loosen the wing nuts and adjust the
motor base by hand or by leveraging against a stationary area. The same principal of adjustment as described
above applies.
On some Cover Installations more than one adjustment will be necessary until
fabric material has been rolled onto the roller drum a number of times and
created it's own memory.
The same method of skew adjustment is the same for either left or
right hand Drive Units.
