Maintenance And Housekeeping Recommendations
WARNING
Walk-in floors can become slippery and hazardous if allowed to become wet, greasy, or icy. Follow maintenance
and housekeeping recommendations outlined below to minimize any hazards.
• Inspect the conditions of abrasive coated anti-skid strips on ramps monthly. Replace or add additional strips when
necessary. Abrasive coated anti-skid strips are factory installed on ramps. Additional strips are available from the factory.
• Keep all walkway surfaces clean and free of spilled liquids and food particles. This includes the floor surface, hardwood
floor racks, and diamond tread plate.
• Inspect refrigeration equipment frequently for proper functioning of evaporators, drain pan heaters, defrost controls, and
drain line heaters. Refer to manufacturers' instructions for the refrigeration system.
• Condensate water must never be allowed to drip on the walk-in floor. Refer to refrigeration system instructions for proper
condensate drain line installation.
• If entry doors are to be held open for periods longer than 5 minutes, a vinyl strip curtain should be used. When doors are
opened for extended periods of time, frost can form on the ceiling and floor due to the excessive condensation of warm
moist air inside the walk-in. This can result in the formation of an ice film on wall, ceiling and floor surfaces or around
gaskets.
• Inspect the door hardware and sweep gasket monthly for ease of operation. Door hardware is self-lubricating and does not
require periodic lubrication. Sweep gasket must be adjusted to allow free movement and proper seal. Any damaged
hardware should be replaced immediately to prevent permanent damage to the door.
• Frost or condensation appearing around the door jamb or heated pressure relief vent indicates that the electric heater is
inoperable, or excessive moisture is present. Check power supply and electrical connections. Replace heaters if necessary.
• All metal surfaces, magnetic door gaskets and door sweep gaskets should be cleaned frequently with a mild detergent and
hot water. Remove all soap film and dry thoroughly with a clean cloth. Never use high pressure hose or large amounts of
water to clean walk-in.
