To re-start your heater, follow these steps:
1. Make sure all hot water taps are closed
and the drain plugs are securely attached.
2. Purge the water line of debris.
3. Open the manual water shut-off valve
located on the water supply line.
4. Open all the hot water taps to verify water
flows to the taps. Then close the hot water
taps.
5. Open the manual gas shut-off valve located
on the gas supply line.
6. Turn on the power supply to the T-M1
Water Heater.
Note:
Do not reverse the hot outlet and cold inlet
connections to the T-M1 Water Heater. This will not
activate the water heater.
Pressure Relief Valve
The MOBIUS T-M1 has a high-temperature
shut off switch built in as a standard safety
feature (called a Hi-Limit switch) therefore a
“pressure only” relief valve is required.
This unit does not come with an approved
pressure relief valve. An approved pressure
relief valve must be installed on the hot water
outlet. The pressure relief valve must conform
to ANSI Z21.22 or CAN 1-4.4 and installation
must follow local code.
The discharge capacity must be at least
235,000 BTU/hr and rated for 150 psi. The
discharge piping for the pressure relief valve
must be directed so that the hot water cannot
splash on anyone or on nearby equipment.
Attach the discharge tube to the pressure relief
valve and run the end of the tube to within 6"
from the floor. This discharge tube must allow
free and complete drainage without any
restrictions.
If the pressure relief valve installed on the T-
M1 discharges periodically, this may be due to
a defective thermal expansion tank or defective
pressure relief valve.
The pressure relief valve must be manually
operated periodically to check for correct
operation.
ELECTRICAL CONNECTIONS
WARNING:
Follow the electrical code
requirements of the local authority having
jurisdiction. In the absence of such
requirements, follow the latest edition of the
National Electrical Code ANSI/NFPA 70 in the
U.S. or the latest edition of CSA C22.1
Canadian Electrical Code, Part 1, in Canada.
The heater must be electrically grounded. Do
not attach the ground wire to either the gas or
the water piping. Plastic pipe or dielectric
unions may isolate the water heater
electrically.
CAUTION:
When servicing or replacing parts
within the T-M1, label all wires prior to
disconnection to facilitate an easy and error
free reconnection. Wiring errors can cause
improper and dangerous operation. Verify
proper operation after servicing.
The MOBIUS T-M1 water heater requires AC
120V 60 Hz electrical power supply that is
properly grounded.
•
An on/off switch controlling the main power
to the T-M1 must be provided for service
reasons;
•
Connect the power supply to the T-M1
exactly as shown in the wiring diagram;
A green screw is provided in the junction box
to ground the connection.
Wiring diagrams are also located on the
inside panel of the appliance.
