  • Page 17: Adjusting Water Flow Using Δt (Delta-T)

    Operate water filtration devices per manufacturer's specifications. Dirty filters can cause a reduction of water flow to the heat pump. An increase of 7-10 psi (48 to 69 kPa) higher than the clean filter pressure typically reduces flow rates. This requires the filter to be cleaned or back-washed. Keep baskets free of debris.

  • Page 18: Maintaining Ability To Winterize

    Temperature differences are based on pool water temperatures of 69° to 75° F. (20.5° to 23.8° C) For water temperatures outside this range, contact Leisure Temp. See "Contacts" on page 1. 1.4.g Maintaining Ability to Winterize Do not glue the threaded portion of the unions. The unions are used to decouple the heat pump from the plumbing system during hard freeze conditions.
  • Page 19 Therefore a water flow switch must be used in place of a water pressure switch to determine if incoming water is being sent to the heat pump. See "Grid Flow Switch (# 0040S)" on page 67. 9. If the heat pump continues to operate without water flow, contact Leisure Temp. Page - 16...
