8. This unit must be grounded per the requirements of applicable electrical codes.
9. Warranty is voided if installation is not made following current Acorn Engineering installation instructions
and if components are assembled to the fixture that is not approved by Acorn Engineering.
10. Fixture is to operate within a water pressure range of 20 PSIG (138 kPa) to 105 PSIG (724 kPa).
Warranty is void if the unit is allowed to operate outside the range of 20 PSIG (138 kPa) to 105 PSIG
(724 kPa). Consult with UPC and local codes for maximum allowable water pressures.
11. Due to cold waste water, Acorn Engineering recommends that p-trap supplied by installer be insulated to
prevent excessive condensation.
12. Per UPC 609.10- All building water supply systems in which quick acting valves are installed shall be
provided with devices to absorb the hammer caused by high pressure resulting from the quick closing of
the valve. These pressure-absorbing devices shall be approved mechanical devices. Water pressure-
absorbing devices will be installed as close as possible to the quick closing valve.
INSTALLATION:
1. Mount hanger bracket to wall horizontally level as shown in Roughing-In and Dimensional Drawing.
Note: Adjust height of bracket if bubbler outlet height is required to vary from that shown. Hanger
Bracket MUST be securely anchored to wall with fasteners sufficient to support 3 times weight of cooler.
If wall can not provide adequate support, order and install optional fixture support carrier.
2. Remove the bottom cover from the water cooler and set aside in a safe place. Save the screws in a
secure location for re-use in later stages of installation.
3. Hang the water cooler on the hanger bracket, ensuring the bracket tabs engage AND seat in the slots in
the back of the water cooler. Verify water cooler is level, left to right AND front to back from bottom of
unit. NOTE: The bubbler stream may be adversely affected if unit is not square and level. Bottom of unit
and louvers should be used as reference to verify unit is square and plumb.
4. Anchor water cooler to wall at other mounting points in base. Shim lower rear mounting points to level
unit if necessary.
5. Thoroughly flush the 3/8” O.D. supply line and then connect water cooler to water supply angle stop
valve (by others) with supplied 3/8” O.D. copper tube.
6. Make up 1-1/4” O.D. p-trap (by others) waste connection.
START UP:
1. Do not connect electrical power to unit: With Bottom Cover removed, turn on fixture water supply and
check all connections for leaks.
2. Air within the Water Cooler system or the structure supply piping will cause an irregular Bubbler outlet
stream until purged out by incoming water. Thoroughly flush and purge air from supply line by
depressing the Pushbutton or activating infrared sensor, until steady water stream is achieved.
3. If water flow requires adjustment, insert a slotted narrow blade screwdriver through the hole centered on
the pushbutton to the flow regulator. Turning clockwise will increase flow and turning counterclockwise
will decrease flow.
4. Recheck all water and drain connections with water flowing through system.
5. With power still NOT connected, carefully manually rotate cooling fan to insure proper clearance and
free fan action.
6. Plug Water Cooler into Electrical Outlet and make sure unit begins to function. IMPORTANT: After turning
power on to initiate cooler and cool down, immediately purge (chiller) water by operating unit continuously for
approx. 1 minute.
IMPORTANT! Thoroughly, inspect all unit connections for water leaks.
7. Assemble bottom cover to water cooler with screws furnished.
