INSTALLATION
BLEED FUNNEL
The bleed funnel reduces the accumulation of salts and
minerals in the cooler. It also acts as an overflow and a drain.
Assemble the bleed funnel as shown.
Make sure the bleed funnel is correctly oriented and that the
O-rings are fitted before placing it into the hole. Screw the nut
up tightly by hand underneath the cooler.
Make sure that you use the correct drain adaptor. Drain-
water from the bleed funnel must be carried away to a suitable
discharge point on the building or property in accordance with
local regulations. Do not drain directly onto the roof surface.
The bleed rate required will vary according to water quality,
but should initially be set to the minimum rate as set out in the
table.
Push the remaining plugs into the blind holes provided. In poor
quality water areas where the salt and mineral contents are
high, adjust the bleed rate by inserting one or more extra plugs
than specified in the table.
Note! In some locations due to regulatory requirements, the
use of bleed funnels are not allowed. In these locations ensure
the plugs are not inserted or are removed from the bleed funnel
entirely.

ELECTRICAL REQUIREMENTS
Installation of the cooler must conform to local electrical rules,
regulations and standards.
Important! It is a requirement of Seeley International that all
coolers be connected to a dedicated circuit to the distribution
board, with a separate circuit breaker and incorporate a separate
isolation switch in accordance with the local wiring rules.
The following specifications for the cooler electrical supply are
required: 115V/60Hz Single Phase.
It is up to the installer to provide a controller and mains power
