RO Cooler only - complete instruction 6,
Filter models - proceed to instruction 7.
Connect a ¼” OD copper tube to the drain fitting
located on the back of the unit. This tube should
be routed to the most convenient drain location
such as a sink drain. (See the Drain Clamp
Assembly instructions in this manual if
applicable). Drain applications routing tubing
from a cooler to the ceiling and then into a drain
is acceptable. Some reduction in membrane
productivity may occur, however, depending on
the height of the ceiling and the source water line
pressure. Some local plumbing codes require
an air gap to be installed between the cooler and
the drain connection. Air gaps are available
from the service department. Check your local
plumbing codes to assure compliance.
7)
To speed up the process of priming the unit, you
may wish to pour 4 gallons (15 liters) of filtered
water into the reservoir. To do so, first remove
the cooler top and remove the reservoir lid (see
“Reservoir Replacement Procedure” under the
service information for the easiest method).
Replace the lid and top after pouring the water
into the reservoir.
8)
Check the available power supply against the
water cooler data plate to assure proper
electrical service. The voltage specification is
115v + 10% and voltage outside of this
specification will affect cooler performance and
could permanently damage the refrigeration
system.
9)
Verify that the hot tank switch is in the “off”
position. Plug power supply cord into receptacle.
10)
Turn on water supply to cooler.
11)
Open each faucet until water flows freely.
12)
On hot tank models, turn on the hot tank by
depressing the switch toward the reset position.
The switch is located inside the access door,
mounted on the column support.
CAUTION: WATER FROM HOT FAUCET CAN
SCALD.
DO NOT USE THE FIRST THREE
RESERVOIRS OF WATER.
SERVICE INFORMATION & GUIDELINES
A)
Lubrication
This unit is equipped with a hermetically sealed
compressor and no periodic lubrication is necessary.
Replacement filter/RO cartridge o-rings should be
lubricated with Dow Corning® Compound 111 or
equivalent, when they are installed.
B)
Periodic Maintenance
1)
The black static condenser on the rear of the
unit must be kept clean of dirt and lint. Visually
inspect every 3 months.
Cleaning Procedure:
a)
Unplug the cooler.
b)
Clean condenser with a small stiff non-wire
brush.
2)
Periodic replacement of the filter/RO cartridges
will be required. The frequency of the change
will be determined by the attributes of the source
water. Foul taste or odor may occur if filters are
not changed at proper intervals.
Filter change procedure:
a)
Prepare a spare filter/RO vessel set in your
shop. Clean and sanitize the vessels and
then install the replacement cartridges per
the instructions in the filter “Installation and
Service Guide”. Then continue with the
following flushing and installation
procedures.
b)
On filtration versions, run a ¼” OD tube from
the blue collet port of the manifold to an off-
center port on the quad lead filter vessel.
Run a ¼” OD tube from the center port to
the nearest drain location. Plug the other
off-center port. Connect a ¼” OD tube from
the water supply to the white collet on the
manifold. Turn on water and flush filters for
10 minutes. Disconnect tubing and plug the
ports. Take this vessel set to the installation
and install it in place of the existing vessel
set. Take the old vessel set back to the
shop for refurbishment.
c)
On reverse osmosis versions, run a ¼” OD
tube from the blue collet port of the manifold
to an off-center port on the quad carbon filter
vessel. Run a ¼” OD tube from the center
port to the nearest drain location. Plug the
other off-center port. Connect a ¼” OD tube
from the gray collet elbow to the yellow collet
elbow. Connect a ¼” OD tube from the
water supply to the right hand white collet
port on pre-filter side. Plug the red collet
port and the smartap port located behind
pre-filter inlet and outlet ports. Turn on
water and flush pre-filter and carbons for 10
minutes. Turn off water. Remove
membrane vessel and discard water. Insert
membrane per “filter installation” on page 2
of the filter “Installation and Service Guide”.
Connect ¼” OD tube from red collet port to
drain. Turn on water and flush 3-4 minutes.
Disconnect tubing used for flushing and plug
all ports.
3)
Reservoir cleaning and sanitizing should be done
each time the filters are changed. Prepare a
spare reservoir assembly following the “Reservoir
Flushing” procedures outlined in the filter
“Installation and Service Guide”. On hot models,
inspect the o-rings in the hot tank fitting and the
reservoir which seal the hot tank opening. These
should be replaced if they show signs of a
flattened diameter.
Reservoir Replacement Procedure:
a)
Remove the top by lifting it up and pressing
in on the cabinet back about 4” (100mm) in
from the side and 2” (5mm) down from the
top.
