InSinkErator HWT300 Digital Instant Hot Water Tank Installation Guide

Welcome and thank you for purchasing this InSinkErator digital instant hot water tank.
WHAT YOU SHOULD KNOW BEFORE YOU BEGIN

Please refer to the Installation, Care & Use manual packaged with your hot water dispenser for additional Important Safety Information and dispenser installation instructions.
⚠ For your satisfaction and safety, read all instructions, cautions and warnings before installing or using this tank. · This particular unit is not for commercial/industrial use. SYSTEM REQUIREMENTS (HOT WATER TANK, DISPENSER AND OPTIONAL FILTRATION SYSTEM):
Make sure that all electrical, plumbing and connections conform to local codes.
A standard, earthed (grounded), ground fault circuit interrupter (GFCI) electrical outlet, with continuous supplied power, is required under the sink for the tank.
This ground fault circuit interrupter (GFCI) outlet must be fused and should not be controlled by the same wall switch that operates the disposer, unless you have a SinkTop SwitchTM from InSinkErator®. Fuse/circuit breaker required is 15 amp for 120 volt.
Do not install on hot water supply lines. The maximum operating water temperature of this system is 100 °F (38 °C). Attach to cold water supply only.
It is recommended that a dedicated control valve be installed on the cold water line supplying water to this system.
To prevent damage or unit not operating properly, the water pressure must be between 30 psi – 80 psi (2.0 bar – 5.5 bar; 103 kPa – 550 kPa). Ambient (room) temperature between 40 °F (4 °C) and 110 °F (43 °C).
Do not install if water pressure exceeds 80 psi (550 kPa). If your water pressure exceeds 80 psi (550 kPa), you must install a pressure limiting valve.
The use of a water filter should NOT result in the water pressure dropping below 15 psi (103 kPa).
Do not install where water hammer conditions occur. If water hammer conditions exist you must install a water hammer arrester.
The flexible vent and outlet tubes must be correctly connected to the dispenser supplied by the manufacturer. They must not be obstructed or connected to a normal type faucet or any other type.
Protect from freezing, shut off water supply, remove filter cartridge, drain hot water tank and tubing when ambient temperatures are expected to drop below 40 °F (4 °C); see Seasonal Storage/Drainage section.
Do not use a torch or other high temperature sources near system, cartridges, plastic fittings or plastic plumbing.
Do not install near water pipes which will be in path of a drilling tool when selecting the position to mount the bracket.
Mount system in such a position as to prevent it from being struck by other items used in the area of installation.
Ensure that the location and fasteners will support the weight of the system when installed and full of water.
When mounting tank and filter, screws provided are for use in wood studs or cabinets only. Use wall anchors (not supplied) for installation into plasterboard.
Ensure all tubing and fittings are secure and free of leaks.
Do not install using rigid piping. System intended for use with plastic water lines (such as PEX tubing, PE tubing, PP tubing).
Do not install this system if any of the quick connect collets are missing from the filter head or Y-Quick Connector. Contact InSinkErator if collets are missing from any fittings.
For systems using two handle HC model faucets, operate only one handle at a time.
Important: Do not allow the unit to continuously boil.
Regularly inspect the system. If there are signs of water leakage, turn off the water supply and contact InSinkErator.
A drain pan, plumbed to an appropriate drain or outfitted with a leak detector, should be used in those applications where any leakage could cause property damage.
If you suspect elevated levels of chlorine in your water, or your water has a rusty appearance before the installation of this unit, use of our water filtration system is recommended.
This product contains stainless steel. The manufacturer cannot guarantee against rusty water because of the number of factors that are involved beyond the manufacturer’s control. However, the sudden appearance of rusty water discharged from the hot water dispenser may indicate the need for service or replacement of this product.
Moving parts inside the tank causing a rattling noise is normal.
For questions or concerns, please contact InSinkErator (see back page for contact information).

ADDITIONAL CONSIDERATION WHEN UTILIZING FILTRATION SYSTEM:
NOTICE

The disposable filter cartridge MUST be replaced every 6 months, or sooner if a noticeable reduction in flow rate occurs.
Failure to replace the disposable filter cartridge may lead to reduced filter performance and cracks in the filter housing, causing water leakage or flooding.
After the recommended usage life, the filter should be disposed of per applicable rules and regulations.
Protect from freezing, remove filter cartridge when ambient temperatures are expected to drop below 40 °F (4 °C).
Do not install systems in areas where ambient temperatures may go above 110 °F (43 °C).
Do not install in direct sunlight or outdoors.

Systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts. A hot water tank, like any water heater, has a limited life and will eventually fail. To avoid possible property damage and personal injury, this hot water tank should be regularly examined for leakage and/or corrosion and replaced when necessary. A drain pan, plumbed to an appropriate drain or outfitted with a leak detector, should be used in those applications where any leakage could cause property damage.
