connection is at the top of the evaporator and both are on the same side. Pay particular attention
to evaporators with dual circuits. Avoid cross-circuiting when installing the new evaporator.
Water Strainer Maintenance
Factory-installed water strainer is a Y-type design. The stainer is equipped with a blow-down valve.
The strainer is a 16 mesh (approximately 1 mm) material.
For maximum efficiency, a differential pressure gauge installed across the inlet and outlet will
indicate pressure loss due to clogging and may be used as a guide to determine when cleaning is
required. The taps for the pressure gauges are included as standard from the factory.
Normally when differential pressure reaches 5-10psi, the screen must be cleaned. The strainer is
equipped with a blow-down valve on the cover plate. To clean open and flush out until any sediment
is removed.
Pump Package Maintenance
Rust Prevention
Pumps not immediately placed into service, or removed from service and stored, must be properly
prepared to prevent excessive rusting.
• Pump port protection plates must not be removed until the pump is ready to connect to the
piping.
• Rotate the shaft periodically (at least monthly) to keep rotating element free and bearings fully
functional.
• For long term storage (3 months or longer), prevent internal rust buildup and possibility of
freezing by performing the following steps:
• Remove the plugs at the top and bottom of the casing.
• Drain or blow out all water.
• As an optional step, it is acceptable to rustproof or pack the casing with moisture
absorbing material and cover the flanges.
