OPERATING PROCEDURES
3.0. Operating Procedures
3.1. Initial Set-Up
3.1.1. Connect the power cord to a standard 115-Volt, Single Phase, 60 Hertz,
grounded power source. Assure that the circuit is sized to provide sufficient
amperage as noted on the Hospi-Gard
IsoClean
®
data plate.
3.1.2. Locate the “ON/OFF” switch on the right side of the unit. The switch is a
maintain contact rocker type.
3.1.3. Turn the Hospi-Gard
IsoClean
®
unit on by pressing downward on the raised
portion of the rocker switch. A slight whirring sound will be heard as the motor
starts. Within 5 to 10 seconds, the module will start to provide clean air into the
environment.
3.2. Speed Adjustment
NOTE:
The Hospi-Gard
IsoClean
unit is set on low at the factory.
3.2.1. To change speeds, remove the exhaust grille by pulling down and lifting out.
3.2.2. Turn the 3-speed switch to the desired setting.
3.2.3. Replace the exhaust grille.
3.3. Airflow Indicator
3.3.1. Locate the airflow indicator on the right side of the unit above the “ON/OFF”
switch. On high speed, the light will turn on when there is sufficient pressure,
indicating the need for a filter change. The airflow indicator should not be used as
the only guide for when a filter change is necessary. The unit should be checked
on a periodic basis to insure recommended room air changes per hour are being
met.
3.3.2. The air velocity generated by the unit may be checked using an airflow
measurement device. The volume of air entering the lower intake grille should
be approximately 550 CFM on low, 700 CFM on medium and 800 CFM on high
with a new filter. See Section 9 for the recommended airflow measurement
procedure.
