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. Ensure external electrical components comply with local
requirements before operating this unit.

Purge Gas Requirements:

A source of purge gas, nitrogen (N
element purge system. All Lufran fluoropolymer inline water heaters use 6.4-mm (0.25-
inch) compression fittings as the purge gas inlet and outlet connections.
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.
