Mounting Equipment; Omnilogic Enclosure - Hayward OmniLogic HLEXPAND Owner's Manual

Installation Steps
DANGER of Death, Injury or Property Damage if procedure not followed. Dead front removal is required for this installation. Power to the HLEXPAND MUST
be shut off whenever the dead front is removed. This means a complete shutdown of power to the entire Expansion Panel.
This manual assumes that you have already installed the OmniLogic that will control this Expansion Panel. Follow the similar installation steps on the following
pages.
Mounting the Equipment
HLEXPAND Enclosure
The HLEXPAND is contained in a raintight enclosure that is suitable for outdoor mounting. The control must be mounted a minimum of 6 ft. (2 meters) horizontal
distance from the pool/spa (or more, if local codes require). The HLEXPAND is designed to mount vertically on a flat surface with the knockouts facing downward.
Because the enclosure also acts as a heat sink (disperses heat from inside the box), it is important not to block the four sides of the control. Do not mount the
HLEXPAND inside a panel or tightly enclosed area.
When selecting a location, note that the standard cables supplied with the included temperature sensors, as well as optional accessories like a Hayward Turbo-
Cell and actuators are all 15 ft. (5m) long. Also, a 15 ft. Ethernet cable is included for connection to the OmniLogic so if mounting further away, you will need
to supply your own cable. An additional Ethernet connection must be made to the home's router or a HLWLAN if remote web connected devices are to be used.
The HLEXPAND weighs close to 60lbs and will require two people to position and install. Select the proper location and mounting hardware given the size and
weight of the unit. The mounting brackets require a total of 6 mounting bolts to fasten the enclosure to the mounting surface.
Note that there is a heat sink on the back of the enclosure. In all cases the heat sink on the back of the enclosure should not contact the wall behind the panel.
This restricts air flow and makes the heat sink less efficient. A minimum separation of 1/8" (except for vinyl siding) should be maintained between any heat
sink pin and the siding on the wall behind the enclosure. In the case of a
flat wall the mounting flanges on the enclosure ensure that the minimum
clearance is maintained. For shingles, clapboards or other siding with a
non-flat profile, the installer must ensure the minimum separation. Refer
to the adjacent diagram.
Special Installation Instructions for Vinyl Siding
IMPORTANT: The heat sink on the back of the HLEXPAND enclosure can-
not be allowed to contact vinyl siding; during normal chlorinator operation
the heat sink pins get warm enough to deform vinyl siding on contact. An
increased minimum separation of 3/8" should be maintained between any
heat sink pin and the vinyl siding behind the enclosure.
Minimum Clearance between heat sink and mounting surface - 1/8"
For Vinyl Siding - 3/8"
