3. Provide mounting surface, sufficient to support the fixture and loads on the fixture.
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).
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.
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.
8.
This unit must be grounded per the requirements of applicable electrical codes.
11. Due to cold waste water, Acorn Engineering recommends that waste piping supplied by installer be insulated
appropriately to prevent excessive condensation.
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.
1. Read all installation instructions carefully, before proceeding.
IMPORTANT:
3.
Waste is 1-1/4” Outer Diameter. Chiller water inlet is 3/8” Outer Diameter copper tube. Chiller water outlet is
3/8” Outer Diameter copper tube. Drinking Fountain water inlet is 1/4” Outer Diameter connection. Bottle
Filler water inlet is 1/4” Outer Diameter connection. Water line by others from in-wall chiller to drinking
fountain must have adequate insulation.
7.
Power supply must be identical in voltage, cycle and phase to that specified on the chiller data plate. Refer to
submittal.
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.
6.
All burrs must be removed from outside of cut tubes before inserting into strainer or other components.
PRIOR TO INSTALLATION:
2.
Provide 4” minimum clear space in front of bottom trim panel and above in-wall chiller to allow for proper
ventilation.
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.
4. Provide rough-ins as shown on the roughing-in and dimensional drawing, including water supply, drain pipe
and electrical service. (See rough-in details)
6. Receptacle(s) must be wired to a GFCI protected circuit. Fixture must be earth grounded per NEC (National
Electrical Code).
7. Completely flush water supply lines of all foreign debris, before connecting to the fixture.
1.
Water Supply Service Stop Valve, Water Connections and Electrical Connections to be supplied by others in
accordance with local codes.
4.
Completely flush supply lines of all foreign debris before connecting to fixture. Chiller is designed to not
cause problems with taste, odor, color, or sediment. Optional water filters (WF1 & WF3), are available for
remote installation should any of these problems arise from the water supply.
