PERFORMANCE

Performance data includes both reheat and DX coil installed.

Note there is little change in air flow with the DX coil removed.

Model 1000RHC and

Model 1000RHCAC

NOTE:

Hydronic reheat coil is designed to temper the ventilation air (after heat recovery) back to room temperature, and is not
intended for use as a primary heating source for the space.

•

Additional controls MUST be added to pump system (not included / not available from Nutech) feeding the coil to ensure
continuous water flow through it, and prevent freezing of the coil.

•

DX coil is designed to reduce humidity brought in from outside during ventilation. Coil MUST be connected to an outdoor
condensing unit (not included) by certified trades person. Not intended as a primary air conditioning system for the space.
