Water Installation - Seeley Breezair EAS265 Installation Manual

Water Installation

A permanent water supply is required to be connected to the float valve
that is factory fitted inside the cooler. The float valve controls the water
level in the pan automatically. The water connection point for DOWN
draft coolers is located underneath the pan, where the ½" float valve
nipple protrudes . (Fig. 12)

The water connection point for SIDE draft coolers is inside the cooler
directly onto the float valve. Route the water supply pipe either through
a hole in the blank front panel of the cooler, or, through a hole in the
pan drilled in any corner adjacent to the corner posts.
Install a manual water shut-off valve near the point of entry of the
water supply to the cooler. In areas subject to winter freezing
install a drain down feature. DO NOT FIT SHUT OFF VALVES
DIRECTLY ONTO THE FLOAT VALVE NIPPLE.
WARNINGS!
1) Flush foreign matter from water supply pipe before final
connection to avoid damage to the float valve.
2) Always ensure that the water supply pipe does not place
sideways pressure onto the float valve nipple as it is plastic.
Overflow & Bleed Off Feature
A special "bleed-off" fitting is supplied with the cooler or in the Power
Pack. It has a 3-fold function: it acts as an overflow, a drain and a
bleed-off. If the water level gets too high the excess water overflows
into the fitting and away to waste. If the user wants to drain the pan he
can lift the fitting out of the drain hole and the pan water will run away
to waste. The bleed function must always be commissioned, except in
areas where it is illegal to run water to waste.

The continuous
bleeding of a small
amount of water to
drain forces fresh water
to enter the cooler and
reduces the rate at
which salt and scale
build up on the pads.
The bleed-off fitting is
inserted into the large
hole already formed in
the pan. (Fig. 13, 20).
Screw the tank nut
firmly under the pan by
hand.
The bleed rate can be
varied according to
local conditions. With all
the plastic plugs
removed from the tray,
minimum bleed will
occur.

Insert plugs to increase the bleed rate to suit your salt build up
experience. See heading Operating Adjustments for further
details. In those areas where draining of bleed-off water is illegal,
the bleed must be disabled. Use the "bleed stop" shield supplied
with the cooler. (Fig. 13)
WARNING! In cases where bleed-off is not used the pads
will require frequent inspection and replacement. Failure to
do so may cause water to leak into the building or onto the
roof, which may enter electrical components creating an
electric shock or fire hazard. Where this condition is
allowed to exist, Seeley International (Americas) accepts no
responsibility for any damage or injury that might occur.
Make sure the fitting is located correctly in relation to the pads
and that the large O-ring is on before placing the fitting into the
hole in the pan. Secure with clips provided. (Fig. 14)

The drain adaptor allows the attachment of a ¾" drain hose to
run water to a waste point. Attach it to the bleed fitting
underneath the pan by using the drain nut. (Fig. 15)
