CAUTION

CAUTION CAUTION

CAUTION

The manufacturer cannot be responsible for the damages caused by improper installation or by failure to follow instructions in this pamphlet. Comply with the installation instructions before completing electric connection.

The thermostat has been pre-set at the factory between 41°C (105° F) and 45° C (113° F).

Hydrogen gas can be produced in a hot water system served by this heater that has not been used for a long period of time (generally 2 weeks or more). Hydrogen gas is extremely flammable. To reduce the risk of injury under these conditions, it is recommended that the hot water faucet be opened for several minutes before using any electrical appliance connected to the hot water system. If hydrogen gas is present, there will probably be an unusual sound such as air escaping through the pipe as the water begins to flow. There should be no smoking or open flame near the faucet at this time.

Any water heater should be installed in such a manner that if it should leak, the resulting flow of water will not cause damage to the area in which it is installed. National Plumbing codes require a drain pan for any water heater installation. Failure to install one is the sole responsibility of owner and/or installer. Reference UPC 2000 (Uniform Plumbing Code) Section 510- Protection from Damage or IPC 2000 (International Plumbing Code) Section 504- Safety Devices.

Installation instructions

MODEL GL 6+

The GL 6+ water heater can be installed under the sink.

Wall mounting (only for vertical installation)

Floor

Mounting

Wiring and Grounding instructions

Fasten the supplied mounting bracket to the wall. Use screws that are suitable for the wall material and the weight of the heater. Hang the water heater on the bracket. Tug down wards on the heater to ensure that both “fingers” of the bracket are seated in the mounting slots. Confirm water piping orientation before wall mounting. Wall bracket will not support the GL6+ when the plumbing connections are installed horizontally.

Heater can sit on floor. Confirm water piping orientation before locating on floor location.

As per the National Electric Code the GL6+ needs to be wired with 12 GA. wire to a minimum

20 amp/ maximum 20 amp branch circuit. To wire the GL6+ model:

1.Pry off the round cover plate (V Fig. 3/1) from its right hand edge (W Fig. 3/1) with a small flat-head screwdriver.

2.Remove the Phillips screw revealed beneath the round cover plate.

3.The cover (C Fig. 3/1) can now be removed by pulling out its left-hand edge. When reassembling, work in the opposite way being careful to insert the tongue of the cover into the slot.

4.Insert 12 AWG through conduit at rear of heater. Secure internal wire connector (A Fig. 3/2) and connect wiring to right side of thermostat control and ground. Positive

(+)to lower terminal marked “L” (E Fig. 3/2) and Neutral to upper terminal marked “N” (H Fig. 3/2). Unit must be grounded at groundscrew (T Fig. 3/2) on element base.

5.When the GL6+ is not within sight of the electrical circuit breakers, a circuit breaker lockout or additional local means of disconnection for all non grounded conductors must be provided that is within sight of the appliance. [REF NEC 422.31]

Pipe connections

Connect the cold water inlet pipe to the inlet nipple (marked with a blue ring) and the hot water outlet pipe to the outlet nipple (marked with a red ring).

The model GL 6+ can be piped horizontally from the side or vertically from the top. If you wish to install the unit horizontally, with the piping connections on the right side, you will have to be certain the tap between the two water tappings is plugged, the supplied Temperature and Pressure Relief Valve will need to be installed on top. See location of T&P relief valve in Fig. 2/2.
