Facility Requirements (Continued):

Water Plumbing Requirements:

This unit is typically supplied with a single inlet and outlet water connection located just inside the rear of
the cabinet. The connections are arranged vertically and do not offset from the horizontal center of the
unit. The inlet plumbing should also include a means to drain the unit for service. There are also
connections for the PRV valve and the leak pan drain. Reference the unit's model number and the model
number key to identify the specific plumbing connections provided with your unit.

Electrical Requirements:

Reference the unit's model number and model number key or the Electrical Specifications Table inside
the front door to identify the electrical power requirements of this unit. In addition, the model number tag
on the front of the unit includes the unit's Wattage, Voltage, Amperage draw and Phase. Verify that the
incoming electrical service is rated and fused for the required amperage draw.

NOTE: Ensure electrical power fusing and disconnects meet local jurisdictional
requirements. Fuse ratings noted in this document are for reference only.

Purge Gas Requirements:

A source of purge gas, nitrogen (N
system. All Lufran fluoropolymer inline water heaters use 6.4-mm (0.25-inch) compression fittings as the
purge gas inlet connection.
The purge gas supply must be regulated between 1.75 – 6.9 bar (25 – 100 psig) gas pressure. Each
heating column inside the unit will use approximately 141 l/hr (5 SCFH) of purge gas.
If the gas pressure is supplied lower than 1.75 bar (25 psi), the control's safety circuitry will disable the
heater and indicate a safety alarm. If the gas pressure exceeds 6.9 bar (100 psi) equipment damage will
result.
