Maintenance Guide - Omega VSHP SERIES Installation And Operation Manual

10. MAINTENANCE GUIDE

Proper unit maintenance will result in optimal unit performance
and prevent potentially costly repairs or property damage. Turn
unit disconnect switch to off and turn unit off at circuit breaker/
fuse panel before starting maintenance procedure.
Do not operate unit without filters or during any
temporary construction that could clog the air filter
or air coil.
Do not use any cleaning solutions that contain acids
on the air-refrigerant coil or any refrigerant compo-
nents.
30 DAY MAINTENANCE
1. Visually inspect filter monthly for dirt and clogging. Re-
place as required with a quality filter.
2. Vacuum dust from unit air grilles and surrounding coil area
with soft bristle brush attachment as required.
3. Filters with a rating higher than MERV 11 may reduce
airflow and increase fan power consumption and unit cool-
ing or heating performance.
4. Every month visually inspect unit for any signs of water
leaks, or water damage around floor or surrounding dry-
wall.
3 MONTH MAINTENANCE
1. Inspect condensate drain every 3 months for signs of
stagnant water, microbial growth, and mineral buildup.
Clean drain pan with an appropriate cleaning solution as
required to prevent condensate hose blockages and mi-
crobial growth.
2. Check valves and hoses for signs of leaks, cracking or
deterioration.
6 MONTH MAINTENANCE
1. Check condensate flow to ensure adequate drainage and
test for signs of impending blockages.
2. Check that condensate alarm is operating correctly. Alarm
trips whenever water level rises above sensor threshold
and locks unit operation.
3. Visually inspect the air coil for signs of dirt accumulation.
Use a mild detergent or coil-cleaning agent. DO NOT use
any cleaning solutions that contain an acid, including ace-
tic acid (vinegar). Damage to the air coil may occur result-
ing in possible refrigerant leaks.
ANNUAL MAINTENANCE
1. Perform an annual maintenance inspection of the fan and
blower motor assembly. All units come with permanently
lubricated fan motors. DO NOT oil or lubricate fan motors.
Clean up any dirt or debris that may have accumulated.
2. Visually inspect the electrical box annually for signs of

component damage due to overheating or poor electrical
contact.
3. Completely clean the interior of the cabinet. Vacuum any
dust or debris.
