5.
Do NOT solder tubes inserted into the chiller, bottle filler or the fountain strainer as damage to the o-rings on
the push-in fittings may result.
2.
Provide 4” minimum clear space in front of upper trim panel and above in-wall chiller to allow for proper
ventilation.
3.
Waste is 1-1/4” Outer Diameter. Chiller water inlet is 3/8” OD copper tube. Chiller water outlet is 3/8” Outer
Diameter copper tube. Drinking Fountain water inlet is 3/8” OD copper tube. Bottle Filler water inlet is 3/8”
OD copper tube. Water line by others from in-wall chiller to drinking fountain must have adequate insulation.
11. Due to cold waste water, Acorn Engineering recommends that waste piping supplied by installer be insulated
appropriately 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 shall be installed as close as possible to the quick closing valve.
PRIOR TO INSTALLATION:
4.
Completely flush supply lines of all foreign debris before connecting to fixture. Water cooler designed to not
cause problems with taste, odor, color, or sediment. Optional water filter (Wf1), is available should any of
these problems arise from the water supply.
6.
All burrs must be removed from outside of cut tubes before inserting into strainer or other components.
1.
Water Supply Service Stop Valve, Water Connections and Electrical Connections to be supplied by others in
accordance with local codes.
1. Read all installation instructions carefully, before proceeding.
8.
This unit must be grounded per the requirements of applicable electrical codes.
5. It is common for electrical equipment to be grounded to water lines either within a structure or away otherwise
remains unchanged by the materials in the water cooler. Every attempt should be made to prevent this kind of
grounding from generating feedback into the water cooler creating electrolysis. Electrolysis will cause a
metallic taste or cause water content to increase.
9.
WARNING: Warranty is voided if installation is not made following current Acorn Engineering installation
instructions and if components are assembled to the fixture that are not approved by Acorn Engineering.
7.
Power supply must be identical in voltage, cycle and phase to that specified on the chiller data plate. Refer to
submittal.
10. Fixture operates within water pressure range of 174 kPa (25 psig) to 724 kPa (105 psig). Acorn Engineering
will not warranty chiller damaged when connected to supply lines with flow pressure lower than 174 kPa (25
psig) or higher than 724 kPa (105 psig). A pressure regulator must be furnished by others on supply line if
inlet pressure is greater than 724 kPa (105 psig).
3. Provide mounting surface, sufficient to support the fixture and loads on the fixture.
2. Carefully remove all fixture components from packaging, preventing scratching or damage. Inspect fixture and
all parts from damages and all parts are bolted on.
4. Provide rough-ins as shown on the roughing-in and dimensional drawing, including water supply, drain pipe
and gravel drain well. (See rough-in details)
7. Completely flush water supply lines of all foreign debris, before connecting to the fixture.
IMPORTANT:
6. Receptacle(s) must be wired to a GFCI protected circuit. Fixture must be earth grounded per NEC (National
Electrical Code).
