Maintenance 139 Maintenance Maintenance and service For information on maintenance and service, refer to the HP website ( http://www.hp.com ). Air and water heat exchanger maintenance The air and water heat exchanger requires no mainte nance. If particulates are present in the cooling water, a filter must be fitted.
Maintenance 140 Before storage or transportation at sub-zero temper atures, the water cycle must be drained completely using compressed air. Avoi d setting the target temper atur e low er than is ne cess ary because the danger of falling below the dew point increases as water temper ature decreases (condensation buildup).
