3.2 START UP / OPERATION PROCEDURE
A. System Fill
1. Foroperatingtemperaturesfrom48°Fto80°Fusewatertolltheunit.
For operating temperatures below 48°F a water and propylene glycol mixture
must be used. An inhibited propylene glycol can be used for operating
temperatures above 48°F if desired to prevent corrosion and scaling. Use the
minimum ratio that is recommended by the glycol manufacturer. See section 8 of
this manual for more information.
2. Theunithasaninternalreservoirwhichmustbelledandmaintainedforproper
operation. The unit has a level switch mounted at the proper water level in the
reservoir. Some units are customized to draw water from an owner supplied
external reservoir and will not have an internal reservoir. These units will normally
have an “R” in the model number. Example: M1D-10AR and are referred to as
“reverseow”.SeeSection6.3.Jformoreinformation.
Please note, Sections 3.2.A & 5.4 are not applicable for reverse ow units.
WARNING: Follow all Factory operations procedures. Failure to do so may create a hazardous
operating condition which may result in serious operator injury and/or unit damage.
NOTICE: See Section 8 of this Manual if using a water & glycol uid mixture.
